CountLoader and GachiLoader Malware Campaigns Target Cracked Software Users

 

Cybersecurity analysts have uncovered a new malware campaign that relies on cracked software download platforms to distribute an updated variant of a stealthy and modular loader known as CountLoader. According to researchers from the Cyderes Howler Cell Threat Intelligence team, the operation uses CountLoader as the entry point in a layered attack designed to establish access, evade defenses, and deploy additional malicious payloads. 

CountLoader has been observed in real-world attacks since at least June 2025 and was previously analyzed by Fortinet and Silent Push. Earlier investigations documented its role in delivering widely used malicious tools such as Cobalt Strike, AdaptixC2, PureHVNC RAT, Amatera Stealer, and cryptomining malware. The latest iteration demonstrates further refinement, with attackers leveraging familiar piracy tactics to lure victims. 

The infection process begins when users attempt to download unauthorized copies of legitimate software, including productivity applications. Victims are redirected to file-hosting platforms where they retrieve a compressed archive containing a password-protected file and a document that supplies the password. Once extracted, the archive reveals a renamed but legitimate Python interpreter configured to run malicious commands. This component uses the Windows utility mshta.exe to fetch the latest version of CountLoader from a remote server.  

To maintain long-term access, the malware establishes persistence through a scheduled task designed to resemble a legitimate Google system process. This task is set to execute every 30 minutes over an extended period and relies on mshta.exe to communicate with fallback domains. CountLoader also checks for the presence of endpoint protection software, specifically CrowdStrike Falcon, adjusting its execution method to reduce the risk of detection if security tools are identified. 

Once active, CountLoader profiles the infected system and retrieves follow-on payloads. The newest version introduces additional capabilities, including spreading through removable USB drives and executing malicious code entirely in memory using mshta.exe or PowerShell. These enhancements allow attackers to minimize their on-disk footprint while increasing lateral movement opportunities. In incidents examined by Cyderes, the final payload delivered was ACR Stealer, a data-harvesting malware designed to extract sensitive information from compromised machines. 

Researchers noted that the campaign reflects a broader shift toward fileless execution and the abuse of trusted, signed binaries. This approach complicates detection and underscores the need for layered defenses and proactive threat monitoring as malware loaders continue to evolve.  

Alongside this activity, Check Point researchers revealed details of another emerging loader named GachiLoader, a heavily obfuscated JavaScript-based malware written in Node.js. This threat is distributed through the so-called YouTube Ghost Network, which consists of hijacked YouTube accounts used to promote malicious downloads. The campaign has been linked to dozens of compromised accounts and hundreds of thousands of video views before takedowns occurred. 

In some cases, GachiLoader has been used to deploy second-stage malware through advanced techniques involving Portable Executable injection and Vectored Exception Handling. The loader performs multiple anti-analysis checks, attempts to gain elevated privileges, and disables key Microsoft Defender components to avoid detection. Security experts say the sophistication displayed in these campaigns highlights the growing technical expertise of threat actors and reinforces the importance of continuously adapting defensive strategies.

Microsoft 365 Users Targeted by Russia-Linked Device Code Phishing Operations


The global network infrastructure is experiencing a wave of sophisticated cyber intrusions as states-sponsored and financially motivated hackers are increasingly exploiting a legitimate Microsoft authentication mechanism to seize control of enterprise accounts in a broad range of sectors. 

There has been a recent investigation which uncovered attackers with ties to both Russian and Chinese interests have been exploiting Microsoft's OAuth 2.0 device authorization grant flow in an effort to deceive users into unknowingly granting them access to their Microsoft 365 environments through this feature designed to simplify secure logins. 

Through the use of fraudulently masquerading institutions and convincing targets to authenticate using authentic Microsoft services, attackers are able to obtain valid access tokens that enable persistent account compromises without requiring the compromise of the target's password. The Russian-linked threat actor Storm-2372 has been targeting government bodies and private organizations since August 2024 and has been one of the most active groups in this regard. 

In order to get the highest level of effectiveness from the device code phishing tactics, it has been proven to be more effective than conventional spear-phishing tactics. It has been conducted throughout Africa, Europe, the Middle East, and North America. Government, defence, healthcare, telecommunications, education, energy, and non-government organizations have been included in the campaign. 

It has been determined that the scale, targeting patterns, and operational discipline of the activity strongly point towards a coordinated nation-state effort aligned with Russian strategic objectives, as confirmed by Microsoft's Threat Intelligence Center. 

The campaign is now more clearly connected to an organization believed to be aligned with the Russian government. It has been a sustained phishing operation that leveraged Microsoft's device code authentication workflow to compromise Microsoft 365 accounts by using a sustained phishing operation. Under the designation UNK_AcademicFlare, Proofpoint has tracked this activity since September 2025 under the designation UNK_AcademicFlare. 

Investigators believe the attackers used email accounts that had previously been compromised from government and military organizations so that they could lend legitimacy to their outreach efforts. In both the United States and Europe, the messages were targeted at individuals and organizations within government agencies, policy think tanks, higher education institutions, and transportation-related organizations. 

There are deliberate steps involved in the approach. It begins with seemingly innocuous correspondence tailored to the recipient’s professional background, usually framed as preparations for an interview or collaboration. In order for victims to be informed, the sender will offer a document purported to outline discussion topics. The document will be hosted at a link that appears to be a Microsoft OneDrive account impersonating the sender.

There is a link within the email that actually redirects users to a Cloudflare Worker, which redirects the user to Microsoft's legitimate account lock page, during which the user enters the provided authentication code, which unwittingly authorizes access and generates a valid token that enables full account hijacking. 

Researchers in the field of cybersecurity note that this technique has gained traction, having been extensively documented earlier this year by Microsoft and Volexity and linked to clusters that are associated with Russia, such as Storm-2372 and APT29. 

Recent warnings from Amazon Threat Intelligence and Volexity have shown that it is still being used by Russian attackers. According to the latest technical details published by Microsoft and independent researchers, there have been several mechanisms behind the campaign that can shed light on the mechanisms that operate behind it. 

A Microsoft disclosure dated February 14, 2025 confirmed that Storm-2372 had begun authenticating through a specific Microsoft Authentication Broker client ID while using the device code sign-in method, which in turn allowed attackers to get refresh access tokens with the new Authentication Broker client ID. 

A device registration token can be exchanged into credentials linked to the device registration service after it has been acquired by an adversary, which makes it possible for that adversary to enroll attacker-controlled systems into Microsoft Entra ID and maintain persistent access for massive email harvesting operations. 

As a result of investigations, high-profile institutions such as the United States Department of State, the Ukrainian Ministry of Defense, the European Parliament, and prominent research organizations have been impersonated in the activities. Researchers have concluded that APT29, a group of malicious actors also known as Cozy Bear, Midnight Blizzard, Cloaked Ursa, and The Dukes, may be the cluster that is driving this activity. 

According to Volexity's case studies, operators are exploiting real-time communication channels as a means of accelerating victim compliance through real-time communication channels. In one incident, UTA0304 contacted a victim via Signal before moving the conversation to Element, and ultimately directed the target to a legitimate Microsoft page asking for an account code, pretending to be a secure chat service provider. 

A malicious attacker might use immediacy and context to convince the victims to act quickly, a tactic similar to those employed by marketing groups to promote Microsoft Teams meetings held by groups related to the phishing attack. 

A response from Microsoft has been to disable the device code flow whenever possible, restrict Entra ID access to trusted networks and devices via Conditional Access, and actively monitor sign-in logs for anomaly activity related to device code, including rapid authentication attempts and logins that originate from unknown locations, in order to prevent this from happening.

It is highly likely that organisations will have to implement layered technical controls in order to reduce exposure to this evolving threat in light of the fact that employee awareness alone cannot counter this evolving threat. In its recommendation to enterprises, Proofpoint recommends explicitly limiting the use of device code authentication. This can be described as the most effective way to prevent misuse of the OAuth device flow by enterprises. 

The adoption of such control systems begins with auditing or report-only deployments, which allows security teams to evaluate potential operational impacts by analyzing historical sign-in data before implementing them in their entirety. 

Providing a more granular, allow-list-based approach where a complete block is not feasible, researchers recommend that device code authentication be limited to narrowly defined and approved scenarios, for example, specific users, operating systems that are trusted, or network locations that are well known.

In addition to these safeguards, additional safeguards can also be implemented by requiring Microsoft 365 sign-ins to originate from compliant or registered devices, particularly in environments that use device registration or Microsoft Intune as authentication methods. Proofpoint warns, however, that misuse of OAuth authentication mechanisms is likely to increase as organizations begin adopting FIDO-compliant multifactor authentication, thus highlighting the need to implement proactive policies and continuous monitoring of these systems. 

Furthermore, researchers have also discovered a broader ecosystem of infrastructure and social engineering techniques that are being used to maintain and expand the campaign, which is ongoing. During the analysis of the phishing URLs, researchers noted that some of them were temporarily inactive. However, the accompanying emails instructed recipients to copy and share the full URL of the browser in case of an error, which is consistent with the tactics used for OAuth device code phishing to extract usable authentication data.

Among the domains involved, ustrs[.]com, seems to have been purchased as a result of a domain auction or resale service. Though the domain was originally registered in early 2020, WHOIS records indicate that it was updated in late 2025, a strategy that has long been used as a way of evading reputation-based security controls that rely heavily on domain age as a signal of trustworthiness.

It was Volexity that observed the same sender approach additional organizations in November 2025, promoting a conference registration link on brussels-indo-pacific-forum[.]org, which has been created to mimic the Brussels Indo-Pacific Dialogue, in an attempt to fool the target audience.

As soon as the victims attempted to sign up for the site, they were presented with a Microsoft 365 authentication process disguised as a legitimate signup process, which then sent them to a benign confirmation page. According to research conducted in connection with Belgrade Security Conference earlier campaigns, subsequent access to compromised accounts was routed through proxy network infrastructures to conceal the attackers' origin, as seen in earlier campaigns. 

Further research has demonstrated that by exploiting standard professional courtesies, operators were systematically extending their reach. When targets declined event invitations, multiple times, as tracked as activity associated with UTA0355, they were urged to register for updates, to share contact details with colleagues who might be interested, and to share contact information with other colleagues who may have been interested as well. 

At least one example involved an unwitting intermediary introducing a new target to the threat actor through an unwitting intermediary, which enabled the attackers to gather new leads organically. In addition, domain registration data related to impersonated events revealed other infrastructure that may have been associated with the same cluster, according to WHOIS data for bsc2025[.]org, a domain resembling Belgrade Security Conference, which was registered using the address mailum[.]com, a relatively unknown e-mail service. 

The Volexity investigation was expanded to identify other domains masquerading as the World Nuclear Exhibition scheduled for November 2025, including world-nuclear-exhibition-paris[.]com, wne-2025[.]com, and confirmyourflight-parisaeroport[.]com, that gave the impression that the World Nuclear Exhibition was being held in Paris. In spite of the fact that researchers do not believe their domains were specifically utilized in confirmed attacks, they can assess that they might have assisted the campaign in its early stages. 

Overall, these findings illustrate a shift in how advanced threat actors are increasingly relying on trusted identity frameworks in place of traditional malware and credential theft in order to carry out their attacks. It has been demonstrated that these campaigns reduce the likelihood of detection, increase user compliance, and decrease the likelihood of detection by weaponizing legitimate authentication flows and embedding them within credible professional interactions.

Organisations may have to deal with longer-term risks associated with persistent access in addition to immediate account compromise, data exposure, internal reconnaissance, and follow-up attacks resulting from persistent access. As a result, security teams are urged to revisit assumptions regarding "trusted" login mechanisms, to improve identity governance, and to ensure visibility into events that do not involve interactive interaction and that are based on a device. 

An attack surface can be significantly reduced by taking proactive measures such as tightening OAuth permissions, auditing registered devices and applications, and stress testing Conditional Access policies. Moreover, leadership and security stakeholders need to be aware that modern phishing campaigns are increasingly modeled on legitimate business workflows, and that defense strategies must be complemented by context-aware user education in order to protect themselves. 

A number of low-friction, high-impact attack techniques are being refined by attackers to gain a higher degree of sophistication, which makes it more challenging for organisations that treat this aspect of their operations as a core operational priority to stop intrusions before they become systemic breaches.

CyberVolk Ransomware Fails to Gain Traction After Encryption Misstep


 

CyberVolk, a pro-Russian hacktivist collective, has intensified its campaign of ransomware-driven intimidation against entities perceived as hostile to Moscow in the past year, marking a notable change in both scale and presentation, marking a notable shift in its operations. 

In addition to its attacks, the group has become increasingly adept at constructing carefully constructed visual branding, including the release of stylized ransomware imagery to publicize successful intrusions in addition to attacking. It seems that these visuals, which were enhanced by deliberately inflammatory language and threatening tone, were not intended simply to announce breaches, but rather to amplify psychological pressure for victims and broader audiences alike. 

In October 2024, CyberVolk appeared to have a clear strategy in the ransoming of several Japanese organizations, including the Japan Oceanographic Data Center and the Japan Meteorological Agency, in which they claimed responsibility for the ransoming. CyberVolk has reportedly altered the desktop wallpapers of several victims prior to starting the encryption process, using the act itself as a signal of control and coercion to control and coerce them. 

CyberVolk's plans to venture into the ransomware-as-a-service ecosystem, however, seem to have been undermined by fundamental technical lapses that were clearly underhand. As part of its strategy to attract affiliates, this group has recently launched a new ransomware strain called VolkLocker, positioning it as a RaaS offering designed to expand its operational reach and attract affiliates. 

A SentinelOne research team has found that the malware has severe cryptographic and implementation weaknesses that greatly reduce its effectiveness, according to a study conducted by researchers. It is worth noting that the encryptor is specifically hardcoded directly into the ransomware binary as well as written in plaintext to a hidden file on compromised systems, compounding the error. 

VolkLocker's credibility and viability within the cybercrime market is severely undermined by the vulnerability of extracting and reusing the exposed key, which could possibly allow organizations to recover their data without having to pay a ransom. As a consequence, affected organizations could potentially recover their data without paying a ransom. 

It was last year when the Infosec Shop and other researchers first started documenting CyberVolk's activities that it caught the attention of the security community, and when it became known that the hacktivist collective was pro-Russian. CyberVolk appears to be operating in the same ideological space as outfits such as CyberArmyofRussia_Reborn and NoName057(16) — both of which have been linked to the Russian military intelligence apparatus and President Vladimir Putin by US authorities. 

However, CyberVolk has yet to be proven to maintain direct ties with the Russian governing authorities. Additionally, CyberVolk has a distinctive operational difference from many of its peers. Compared to comparable hacktivist teams, which tend to focus their efforts on disruption but low-impact distributed denial-of-service attacks, CyberVolk has consistently utilized ransomware as part of its campaigns. 

Researchers have noted that after repeated bans from Telegram in 2025, the group almost disappeared from public view for the first half of 2025, only to resurface in August with a revamped ransomware service based on VolkLocker. In analyzing the operations, it is evident that an uneven scaling attempt has taken place, combining fairly polished Telegram automation with malware payloads that retain signs of testing and incomplete hardening. 

VolkLocker is written in Go and designed to work across both Windows and Linux environments. In addition to enabling user communication, Telegram-based command-and-control functionality, it also handles system reconnaissance, decryption requests, and the decryption of sensitive data. In order to configure new payloads, affiliates must provide operational details such as Bitcoin payment addresses, Telegram bot credentials, encryption deadlines, file extensions, and self-destruct parameters. 

Among the backbones of this ecosystem is Telegram, which is responsible for providing communication, tool distribution, and customer support services. However, some operators have reported extending the default C2 framework to include keylogging and remote access capabilities. As of November, the group was advertising standalone remote access trojans and keyloggers in addition to its RaaS offerings, and these packages included tiered pricing options. 

The ransomware is capable of escalating privileges, bypassing Windows User Account Control, selectively encrypting files based on pre-defined exclusion rules, and applying AES-256 encryption in GCM mode, which emphasizes CyberVolk's ongoing attempts to mix ideological messaging with the increasingly commercialized nature of cybercrime. 

In the course of further technical analysis of VolkLocker, it has been revealed that the ransomware has been shaped by an aggressive design choice and critical implementation errors. One of the most notable features of the program is its integration of a timer function written in Go that can be configured to initiate a destructive wipe upon expiration of the countdown or upon entering an incorrect password into the ransom note in HTML.

Upon activation, the routine targets the most common user directories, such as Documents, Downloads, Pictures, and the Desktop, making the users vulnerable to permanent data loss. In order to access CyberVolk's ransomware-as-a-service platform, one must pay approximately $800 to $1,100 for an operating system that supports just one operating system, or $1,600 to $2,200 for a build that supports both Windows and Linux operating systems. 

In the early days of the group, affiliates obtained the malware by using Telegram-based builder bots that were able to customize encryption parameters and create customized payloads, indicating that the group relied heavily on Telegram as a delivery and coordination platform. 

As of November 2025, the same operators have expanded their commercial offerings, advertising standalone remote access trojans and keyloggers for $500 each, further signaling a desire to diversify their offerings from merely ransomware to a wide range of security technologies. Nevertheless, VolkLocker’s operations have a serious cryptographic weakness at the core of their operation that makes it difficult for them to be effective. 

As part of the encryption process, AES-256 is employed in Galois/Counter Mode and a random 12-byte nonce is generated for each file before it deletes the original and adds extensions such as .locked or .cvolk to the encrypted copies after destroying the original files. Although the system seems to be designed to be quite strong, researchers found that all files on a victim's system are encrypted using a single master key which is derived from a 64-character hexadecimal string embedded directly in the binary files. 

Additionally, the same key is stored in plaintext to a file named system_backup.key, which is never removed, compounding the problem. This backup appears to be a testing artifact that was inadvertently left in production builds, and SentinelOne suggests that it might be able to help victims recover their data without paying a ransom for it. 

While the flaw offers a rare advantage to those already affected, it is expected that when it is disclosed to the public, the threat actors will take immediate steps to remedy the issue. The majority of security experts advise that, generally, the best way to share such weaknesses with law enforcement and ransomware response specialists while an operation is ongoing, is by utilizing private channels. This is done in order to maximize victim assistance without accelerating adversary adaptation, thus maximizing victim assistance without accelerating adversary adaptation. 

The modern cyber-extortion economy is sustained by networks of hackers, affiliates, and facilitators that work together to run these campaigns. In order to understand this landscape effectively, open-source intelligence was gathered from social media activity and media reporting. These activities highlighted the existence of a broad range of actors operating within it. 

One such group is the Ukrainian-linked UA25 collective, whose actions retaliate against Russian infrastructure are often accompanied by substantial financial and operational damage, with a claim to responsibility publicly made in the media. In such cases, asymmetrical cyber conflict is being highlighted, where loosely organized non-state actors are able to cause outsized damage to much larger adversaries, underscoring the asymmetrical nature of contemporary cyber conflict. 

In this climate, Russian cybercriminal groups are often able to blur the line between ideological alignment and financial opportunism, pushing profit-driven schemes under the banner of political activism in an effort to achieve political goals. CyberVolk is an example of this hybrid model: CyberVolk aims to gain legitimacy through hacktivist rhetoric while also engaging in extortion and tool sales to monetize its ransomware activity. 

Security firms and independent researchers have been continuously scrutinizing the situation, which has led, in the past few years, to expose internal operational weaknesses, including flawed cryptographic practices, insecure key handling, which can be leveraged to disrupt campaigns and, in some cases, aid law enforcement and takedown efforts on a broader scale. This has been reported as well by publications such as The Register. 

In the near-term, analysts warn that ransomware operations will likely get more sophisticated and destructive - with future strains of ransomware increasingly incorporating elements commonly associated with wiper malware, which encrypts data rather than issuing ransoms. There have been several regulatory actions, sanctions, and government advisories issued throughout 2025 that have laid the foundation for a more coordinated international response to these threats. 

However, experts warn that meaningful progress will depend on a sustained cooperation between governments, technology companies, and private sector firms. In the case of CyberVolk, the technical ambition often outweighs the execution, yet even faulty operations demonstrate a persistent threat from Russian-linked actors, who continue to adapt despite mounting pressures from the West. 

In the wake of recent sanctions targeting key enablers, some parts of this ecosystem have been disrupted; however, new infrastructure and service providers are likely to fill these gaps as time goes on. Defensers should take note of the following lesson: continued vigilance, proactive threat hunting, as well as adopting advanced detection and response capabilities remain essential for preventing ransomware from spreading, as the broader contest against ransomware increasingly depends on converting adversaries' mistakes into durable security advantages to ensure the success of the attack. 

It should be noted that the rise and subsequent missteps of CyberVolk can be considered a timely reminder that the ransomware landscape is evolving in multiple ways, not only in terms of technical sophistication but also in terms of narrative strategy and operational ambition. 

Although advocates of groups may work to increase their impact by using political messaging, branding, and service models that are tailored for commercialization, long-term success remains dependent on disciplined engineering and operational security-areas in which even ideologically motivated actors continue to fail. 

Organizations should take this episode as an example of the importance of building multilayered defenses that go beyond perimeter security to include credential hygiene, behavioral monitoring, and rapid incident response planning in addition to regular patching, offline backups, and tabletop exercises. This episode emphasizes how vital it is to engage with threat intelligence providers in order to identify emerging patterns before they turn into operational disruptions. 

In the eyes of policymakers and industry leaders, the case highlights the benefits of coordinated disclosure practices and cross-border collaboration as means of weakening ransomware ecosystems without inadvertently making them more refined. 

Iterating and rebranding ransomware groups can be equally instructive as iterating and rebranding their malware, providing defenders with valuable opportunities to anticipate next moves and close gaps before they are exploited. The ability to survive in an environment characterized by both sides adapting will increasingly depend on turning visibility into action and learning from every flaw that has been exposed.

Aisuru Botnet Unleashes Record 29.7 Tbps DDoS Attack

 

A new record-breaking 29.7 Tbps distributed denial-of-service (DDoS) attack launched via the Aisuru botnet has set a new standard for internet disruption and reinforced that multi-terabit attacks are on track to soon be an everyday event for DDoS defenders. According to Cloudflare’s latest DDoS threats report, Aisuru launched an intense hyper-volumetric DDoS on a network layer with traffic that reached 29.7 Tbps and 14.1 billion packets per second, reaching new heights beyond previous records that topped 22 Tbps. 

The DDoS attack employed a UDP ‘carpet bombing’ technique that targeted 15,000 destination ports every second with random packet components constantly varying so as not to get filtered out at traditional scrubbing centers. Despite these efforts, Cloudflare reports that Aisuru traffic took mere seconds for an autonomous mitigation system to identify and remove. 

Behind the incident is a botnet Cloudflare now estimates at 1 million to 4 million compromised devices, making Aisuru the biggest DDoS botnet in active circulation. Since the start of 2025, Cloudflare has mitigated 2,867 Aisuru incidents, with 1,304 hyper-volumetric attacks in the third quarter alone - a 54% quarter-over-quarter increase that equates to about 14 mega-events a day. Segments of the botnet are openly leased as "chunks", allowing buyers to rent enough power to take down backbone connections or perhaps even national ISPs for mere hundreds or thousands of dollars apiece.

Cloudflare thwarted a total of 8.3 million DDoS attacks in the third quarter of 2025, a 15% increase from the prior quarter and 40% year-over-year, while marking the 2025 year-to-date total at 36.2 million - already 170% of all attacks recorded in 2024 and still one full quarter away. 

About 71% of Q3 attacks were network-layer traffic, which soared 87% QoQ and 95% YoY, while HTTP-layer events fell 41% QoQ and 17% YoY, indicating a strategic swing back to pure bandwidth and transport-layer exhaustion. The extremes are picked up the most: incidents over 100 Mpps jumped 189% QoQ, and those above 1 Tbps increased by 227%, though many ended within 10 minutes, too late for any effective intervention by manual actions or DDoS-on-demand mitigation programs.

Collateral damage continues to escalate as well. KrebsOnSecurity reports Aisuru-driven traffic has already caused severe outages at U.S. internet services not targeted as main victims. Cloudflare data shows Aisuru and actors like it have targeted telecoms, gaming, hosting, and financial services intensely. Information Technology and Services, telecoms, gambling and casinos are among the toughest hit sectors in Q3. 

Geopolitics and societal unrest are increasingly reflected in attack behavior. DDoS traffic against generative AI service providers jumped as high as 347% month-over-month in September, and DDoS attacks on mining, minerals and metals, and autos failed to lag as tensions escalated involving EV tariffs and China and the EU.

Indonesia continues as source number one for DDoS traffic, registering an astonishing 31,900% increase in HTTP DDoS requests since 2021, and there were sharp increases in Q3 2025 for the Maldives, France, and Belgium, reflecting massive protests and worker walkouts. China stayed the most‑targeted country, followed by Turkey and Germany, with the United States climbing to fifth and the Philippines showing the steepest rise within the top 10, underscoring how modern DDoS campaigns now track political flashpoints, public anger, and regulatory fights over AI and trade almost in real time.

Rising Prompt Injection Threats and How Users Can Stay Secure

 


The generative AI revolution is reshaping the foundations of modern work in an age when organizations are increasingly relying on large language models like ChatGPT and Claude to speed up research, synthesize complex information, and interpret extensive data sets more rapidly with unprecedented ease, which is accelerating research, synthesizing complex information, and analyzing extensive data sets. 

However, this growing dependency on text-driven intelligence is associated with an escalating and silent risk. The threat of prompt injection is increasing as these systems become increasingly embedded in enterprise workflows, posing a new challenge to cybersecurity teams. Malicious actors have the ability to manipulate the exact instructions that lead an LLM to reveal confidential information, alter internal information, or corrupt proprietary systems in such ways that they are extremely difficult to detect and even more difficult to reverse. 

Malicious actors can manipulate the very instructions that guide an LLM. Any organisation that deploys its own artificial intelligence infrastructure or integrates sensitive data into third-party models is aware that safeguarding against such attacks has become an urgent concern. Organisations must remain vigilant and know how to exploit such vulnerabilities. 

It is becoming increasingly evident that as organisations are implementing AI-driven workflows, a new class of technology—agent AI—is beginning to redefine how digital systems work for the better. These more advanced models, as opposed to traditional models that are merely reactive to prompts, are capable of collecting information, reasoning through tasks, and serving as real-time assistants that can be incorporated into everything from customer support channels to search engine solutions. 

There has been a shift into the browser itself, where AI-enhanced interfaces are rapidly becoming a feature rather than a novelty. However, along with that development, corresponding risks have also increased. 

It is important to keep in mind that, regardless of what a browser is developed by, the AI components that are embedded into it — whether search engines, integrated chatbots, or automated query systems — remain vulnerable to the inherent flaws of the information they rely on. This is where prompt injection attacks emerge as a particularly troubling threat. Attackers can manipulate an LLM so that it performs unintended or harmful actions as a result of exploiting inaccuracies, gaps, or unguarded instructions within its training or operational data. 

Despite the sophisticated capabilities of agentic artificial intelligence, these attacks reveal an important truth: although it brings users and enterprises powerful capabilities, it also exposes them to vulnerabilities that traditional browsing tools have not been exposed to. As a matter of fact, prompt injection is often far more straightforward than many organisations imagine, as well as far more harmful. 

There are several examples of how an AI system can be manipulated to reveal sensitive information without even recognising the fact that the document is tainted, such as a PDF embedded with hidden instructions, by an attacker. It has also been demonstrated that websites seeded with invisible or obfuscated text can affect how an AI agent interprets queries during information retrieval, steering the model in dangerous or unintended directions. 

It is possible to manipulate public-facing chatbots, which are intended to improve customer engagement, in order to produce inappropriate, harmful, or policy-violating responses through carefully crafted prompts. These examples illustrate that there are numerous risks associated with inadvertent data leaks, reputational repercussions, as well as regulatory violations as enterprises begin to use AI-assisted decision-making and workflow automation more frequently. 

In order to combat this threat, LLMs need to be treated with the same level of rigour that is usually reserved for high-value software systems. The use of adversarial testing and red-team methods has gained popularity among security teams as a way of determining whether a model can be misled by hidden or incorrect inputs. 

There has been a growing focus on strengthening the structure of prompts, ensuring there is a clear boundary between user-driven content and system instructions, which has become a critical defence against fraud, and input validation measures have been established to filter out suspicious patterns before they reach the model's operational layer. Monitoring outputs continuously is equally vital, which allows organisations to flag anomalies and enforce safeguards that prevent inappropriate or unsafe behaviour. 

The model needs to be restricted from accessing unvetted external data, context management rules must be redesigned, and robust activity logs must be maintained in order to reduce the available attack surface while ensuring a more reliable oversight system. However, despite taking these precautions to protect the system, the depths of the threat landscape often require expert human judgment to assess. 

Manual penetration testing has emerged as a decisive tool, providing insight far beyond the capabilities of automated scanners that are capable of detecting malicious code. 

Using skilled testers, it is possible to reproduce the thought processes and creativity of real attackers. This involves experimenting with nuanced prompt manipulations, embedded instruction chains, and context-poisoning techniques that automatic tools fail to detect. Their assessments also reveal whether security controls actually perform as intended. They examine whether sanitisation filters malicious content properly, whether context restrictions prevent impersonation, and whether output filters intervene when the model produces risky content. 

A human-led testing process provides organisations with a stronger assurance that their AI deployments will withstand the increasingly sophisticated attempts at compromising them through the validation of both vulnerabilities and the effectiveness of subsequent fixes. In order for user' organisation to become resilient against indirect prompt injection, it requires much more than isolated technical fixes. It calls for a coordinated, multilayered defence that encompasses both the policy environment, the infrastructure, and the day-to-day operational discipline of users' organisations. 

A holistic approach to security is increasingly being adopted by security teams to reduce the attack surface as well as catch suspicious behaviour early and quickly. As part of this effort, dedicated detection systems are deployed, which will identify and block both subtle, indirect manipulations that might affect an artificial intelligence model's behaviour before they can occur. Input validation and sanitisation protocols are a means of strengthening these controls. 

They prevent hidden instructions from slipping into an LLM's context by screening incoming data, regardless of whether it is sourced from users, integrated tools, or external web sources. In addition to establishing firm content handling policies, it is also crucial to establish a policy defining the types of information that an artificial intelligence system can process, as well as the types of sources that can be regarded as trustworthy. 

A majority of organisations today use allowlisting frameworks as part of their security measures, and are closely monitoring unverified or third-party content in order to minimise exposure to contaminated data. Enterprises are adopting strict privilege-separation measures at the architectural level so as to ensure that artificial intelligence systems have minimal access to sensitive information as well as being unable to perform high-risk actions without explicit authorisations. 

In the event that an injection attempt is successful, this controlled environment helps contain the damage. It adds another level of complexity to the situation when shadow AI begins to emerge—employees adopting unapproved tools without supervision. Consequently, organisations are turning to monitoring and governance platforms to provide insight into how and where AI tools are being implemented across the workforce. These platforms enable access controls to be enforced and unmanaged systems to be prevented from becoming weak entry points for attackers. 

As an integral component of technical and procedural safeguards, user education is still an essential component of frontline defences. 

Training programs that teach employees how to recognise and distinguish sanctioned tools from unapproved ones will help strengthen frontline defences in the future. As a whole, these measures form a comprehensive strategy to counter the evolving threat of prompt injection in enterprise environments by aligning technology, policy, and awareness. 

It is becoming increasingly important for enterprises to secure these systems as the adoption of generative AI and agentic AI accelerates. As a result of this development, companies are at a pivotal point where proactive investment in artificial intelligence security is not a luxury but an essential part of preserving trust, continuity, and competitiveness. 

Aside from the existing safeguards that organisations have already put in place, organisations can strengthen their posture even further by incorporating AI risk assessments into broader cybersecurity strategies, conducting continuous model evaluations, as well as collaborating with external experts. 

An organisation that encourages a culture of transparency can reduce the probability of unnoticed manipulation to a substantial degree if anomalies are reported early and employees understand both the power and pitfalls of Artificial Intelligence. It is essential to embrace innovation without losing sight of caution in order to build AI systems that are not only intelligent, but also resilient, accountable, and closely aligned with human oversight. 

By harnessing the transformative potential of modern AI and making security a priority, businesses can ensure that the next chapter of digital transformation is not just driven by security, but driven by it as a core value, not an afterthought.

CastleLoader Widens Its Reach as GrayBravo’s MaaS Infrastructure Fuels Multiple Threat Clusters

 

Researchers have now identified four distinct threat activity clusters associated with the malware loader CastleLoader, bolstering previous estimates that the tool was being supplied to multiple cybercriminal groups through a malware-as-a-service model. In this, the operator of this ecosystem has been dubbed GrayBravo by Recorded Future's Insikt Group, which had previously tracked the same actor under the identifier TAG-150. 

CastleLoader emerged in early 2025 and has since evolved into a dynamically developing malware distribution apparatus. Recorded Future's latest analysis underscores GrayBravo's technical sophistication, the ability to promptly adapt operations after public reporting, and the growing infrastructure currently supporting multiple threat campaigns. 

GrayBravo's toolkit consists of several components, including a remote access trojan dubbed CastleRAT and a modular malware framework named CastleBot. CastleBot is composed of three interconnected main elements: a shellcode stager, a loader, and a core backdoor. The loader injects the backdoor into memory, following which the malware communicates with command-and-control servers to receive instructions. These further enable downloading and executing a variety of payloads in the form of DLL, EXE, and PE files. CastleLoader has been used to distribute various well-known malware families, including RedLine Stealer, StealC, DeerStealer, NetSupport RAT, SectopRAT, MonsterV2, WARMCOOKIE, and other loaders, such as Hijack Loader, which demonstrates how well the CastleBot and CastleLoader combo serves as a widely useful tool.  

Recorded Future's new discoveries uncover four separate operational clusters, each using CastleLoader for its purposes. One cluster, attributed to TAG-160, has been operational since March 2025, targeting the logistics industry by leveraging phishing lures and ClickFix for CastleLoader delivery. Another one, referred to as TAG-161, started its operations in June 2025 and has used Booking.com-themed ClickFix campaigns for spreading CastleLoader and Matanbuchus 3.0. One more cluster has utilized infrastructure that spoofs Booking.com, complementing the spoofing with ClickFix and leveraging Steam Community pages as dead-drop resolvers to distribute CastleRAT via CastleLoader. A fourth cluster, which has been active since April 2025, leverages malvertising and fake update notices posing as Zabbix and RVTools for delivering CastleLoader together with NetSupport RAT. 

The actor's infrastructure spans from victim-facing command-and-control servers attributed to CastleLoader, CastleRAT, SectopRAT, and WARMCOOKIE to several other VPS servers, presumably held as spares. Of special interest are the TAG-160 operations, which feature the use of hijacked or fake accounts on freight-matching platforms, including DAT Freight & Analytics and Loadlink Technologies, to create rather plausible phishing messages. The customised lures suggest that the operators have extensive domain knowledge of logistics processes and related communication practices in the industry. 

Recorded Future concluded that the continued expansion in the use of CastleLoader by independent threat groups testifies to how rapidly such advanced and adaptive tools can diffuse in the cybercrime ecosystem once they get credit. Supporting this trend, the recent case documented by the researchers at Blackpoint involved a Python-based dropper chain in which the attackers used ClickFix to download an archive, stage files in the AppData directory, and execute a Python stager that rebuilt and launched a CastleLoader payload. Continued evolution of these delivery methods shows that the malware-as-a-service model behind CastleLoader is really enabling broader and more sophisticated operations through multiple threat actors.

Researchers Find Massive Increase in Hypervisor Ransomware Incidents


Rise in hypervisor ransomware incidents 

Cybersecurity experts from Huntress have noticed a sharp rise in ransomware incidents on hypervisors and have asked users to be safe and have proper back-up. 

The Huntress case data has disclosed a surprising increase in hypervisor ransomware. It was involved in malicious encryption and rose from a mere three percent in the first half to a staggering 25 percent in 2025. 

Akira gang responsible 

Experts think that the Akira ransomware gang is the primary threat actor behind this, other players are also going after hypervisors to escape endpoint and network security controls. According to Huntress threat hunters, players are going after hypervisors as they are not secure and hacking them can allow hackers to trigger virtual machines and manage networks.

Why hypervisors?

“This shift underscores a growing and uncomfortable trend: Attackers are targeting the infrastructure that controls all hosts, and with access to the hypervisor, adversaries dramatically amplify the impact of their intrusion," experts said. The attack tactic follows classic playbook. Researchers have "seen it with attacks on VPN appliances: Threat actors realize that the host operating system is often proprietary or restricted, meaning defenders cannot install critical security controls like EDR [Endpoint Detection and Response]. This creates a significant blind spot.”

Other instances 

The experts have also found various cases where ransomware actors install ransomware payloads directly via hypervisors, escaping endpoint security. In a few cases, threat actors used built-in-tools like OpenSSL to run encryption of the virtual machine volume without having to upload custom ransomware binaries.

Attack tactic 

Huntress researchers have also found attackers disrupting a network to steal login credentials and then attack hypervisors.

“We’ve seen misuse of Hyper-V management utilities to modify VM settings and undermine security features,” they add. “This includes disabling endpoint defenses, tampering with virtual switches, and preparing VMs for ransomware deployment at scale," they said.

Mitigation strategies 

Due to the high level of attacks on hypervisors, experts have suggested admins to revisit infosec basics such as multi-factor authentication and password patch updates. Admins should also adopt hypervisor-specific safety measures like only allow-listed binaries can run on a host.

For decades, the Infosec community has known hypervisors to be an easy target. In a worst-case scenario of a successful VM evasion where an attack on a guest virtual machine allows hijacking of the host and its hypervisor, things can go further south. If this were to happen, the impact could be massive as the entire hyperscale clouds depend on hypervisors to isolate tenants' virtual systems.

Initial Access Brokers Now Central to Cyberattacks: Report

 

The market for initial access brokers has expanded rapidly over the past two years, creating a system that allows advanced threat actors to outsource the early stages of an intrusion, according to new research from Check Point. The report says this growth has made it easier for both nation-state groups and criminal actors to breach a larger number of targets. 

Check Point notes that the rise of the IAB economy coincides with the growing use of cyberspace by governments as a tool for projecting power. The firm is urging policymakers and businesses to strengthen identity security, secure software supply chains and improve the resilience of operational technology systems. 

“Once considered peripheral players, IABs have become a critical node in the cyber-criminal supply chain, lowering barriers to entry for sophisticated operations and enabling rapid campaign scaling,” Check Point said. 

By paying IABs to handle initial access at scale, threat actors can move faster and avoid the risks associated with the early stages of an attack. According to the report, “state-backed groups and sophisticated criminal actors can reduce operational risk, accelerate execution timelines, and scale their campaigns across dozens of targets simultaneously.” 

This growing reliance on brokers also complicates attribution. When an IAB is involved, IT teams and investigators often struggle to determine whether an attack was carried out by a government-backed group or by a criminal operation. 

For this reason, Check Point says that “IAB activity is no longer a peripheral criminal phenomenon but a force multiplier in the broader offensive ecosystem, one that directly supports espionage, coercive operations, and potential disruption of U.S. government and critical infrastructure networks.” 

The report also highlights a sharp rise in IAB activity targeting essential sectors. Healthcare saw nearly 600 percent more IAB-related attacks in 2024 compared with 2023. Government, education and transportation networks were also significantly affected. 

Check Point says these increases reflect both higher demand from adversaries for access to sensitive environments and the growing professionalisation of the IAB marketplace, where access to critical systems is treated as a commodity. 

The research links this broader trend to rising geopolitical tensions and the changing role of nation-state hacking. “Cyber operations have evolved from opportunistic disruptions and intelligence-gathering into deliberate, coordinated campaigns designed to achieve political, economic, and strategic outcomes,” the report says. 

According to Check Point, the line between geopolitics and cyber activity has largely disappeared. State-aligned groups are using digital operations to shape crises, signal intent and impose costs on rivals, often below the threshold of open conflict. 

The firm notes that spikes in geopolitical risk are closely followed by spikes in targeted cyberattacks against U.S. government systems. “Cybersecurity is no longer just a technical issue; it is a strategic imperative,” Check Point said. The report argues that resilience, deterrence and rapid recovery must now be treated as national security priorities on the same level as traditional defence planning.

Critical CVE-2025-66516 Exposes Apache Tika to XXE Attacks Across Core and Parser Modules

 

A newly disclosed vulnerability in Apache Tika has had the cybersecurity community seriously concerned because researchers have confirmed that it holds a maximum CVSS severity score of 10.0. Labeled as CVE-2025-66516, the vulnerability facilitates XXE attacks and may allow attackers to gain access to internal systems along with sensitive data by taking advantage of how Tika processes certain PDF files. 

Apache Tika is an open-source, highly-used framework for extracting text, metadata, and structured content from a wide array of file formats. It is commonly used within enterprise workflows including compliance systems, document ingestion pipelines, Elasticsearch and Apache Solr indexing, search engines, and automated content scanning processes. Because of its broad use, any severe issue within the platform has wide-ranging consequences.  

According to the advisory for the project, the vulnerability exists in several modules, such as tika-core, tika-parsers, and the tika-pdf-module, on different versions, from 1.13 to 3.2.1. The issue allows an attacker to embed malicious XFA -- a technology that enables XML Forms Architecture -- content inside PDF files. Upon processing, Tika may execute unwanted calls to embedded external XML entities, thus providing a way to fetch restricted files or gain access to internal resources.  

The advisory points out that CVE-2025-66516 concerns an issue that was previously disclosed as CVE-2025-54988, but its scope is considerably broader. Whereas the initial advisory indicated the bug was limited to the PDF parser, subsequent analysis indicated that the root cause of the bug-and therefore the fix-represented in tika-core, not solely its parser component. Consequently, any organization that has patched only the parser without updating tika-core to version 3.2.2 or newer remains vulnerable. 

Researchers also provided some clarification to note that earlier 1.x releases contained the vulnerable PDF parser in the tika-parsers module, so the number of affected systems is higher than initial reporting indicated. 

XXE vulnerabilities arise when software processes XML input without required restrictions, permitting an attacker to use external entities (these are references that can point to either remote URLs or local files). Successfully exploited, this can lead to unauthorized access, SSRF, disclosure of confidential files, or even an escalation of this attack chain into broader compromise. 

Project maintainers strongly recommend immediate updates for all deployments. As no temporary configuration workaround has been confirmed, one can only install patched versions.

FinCEN: Ransomware Gangs Extorted Over $2.1B from 2022 to 2024

 

FinCEN’s most recent report has revealed that ransomware activity reached a new peak in 2023, accumulating over $1.1 billion in payments before a decline in 2024, as law enforcement pursued major gangs such as ALPHV/BlackCat, LockBit. In general, FinCEN data reveals $2.1 billion in ransoms paid from 2022 through 2024, and about $4.5 billion from 2013 to 2024. 

FinCEN’s findings draw on thousands of Bank Secrecy Act reports, that registered 4,194 ransomware incidents between January 2022 and December 2024. Ransomware earnings peaked 2023 with 1,512 incidents and a 77% increase in payouts from 2022, but dropped to nearly $734 million in 1,476 incidents during 2024, decrease attributed to the global disruption of the BlackCat and LockBit operations. These takedowns left affiliates to either transition to other ransomware brands or try to rebuild. 

The report does note that most single ransom amounts were under $250,000, although some sectors consistently took the biggest hits. By number of incidents, manufacturing, financial services, healthcare, retail, and legal services were the most frequently targeted industries from 2022 to 2024. By total losses, financial services led with about $365.6 million paid, followed by healthcare, manufacturing, science and technology, and retail, each suffering hundreds of millions in extorted funds.

Over the period under review, FinCEN counted 267 unique ransomware families; however, a handful caused the majority of distraught. Akira accounted for the most reports (376), followed by ALPHV/BlackCat with the highest earnings at close to $395 million, and LockBit with $252.4 million. As for the top 10 most active groups, they were a combined $1.5 billion between 2022 and 2024, featuring Black Basta, Royal, BianLian, Hive, Medusa, and Phobos. 

The flow of money is still largely in cryptocurrency, with around 97% of ransom payments in Bitcoin and the remainder in Monero, Ether, Litecoin and Tether. Notification of Ransomware Incident to FBI FinCEN stressed that routine, detailed reporting of ransomware incidents to the FBI and ransom payments to FinCEN continues to be critical to enable tracking of funds, further disrupting them, and sustaining the pressure that resulted in the decline noted in 2024.

Cyberattacks Target Seven Major Indian Airports Through GPS Spoofing

 

The Indian Ministry of Home Affairs has revealed that seven key airports in the country were hit by GPS spoofing cyber attacks in November 2025, Union Civil Aviation Minister Ram MohanNaidu said. The airports affected are the Indira Gandhi International Airport in Delhi, the Chhatrapati Shivaji Maharaj International Airport in Mumbai, and those in Kolkata, Hyderabad, Bengaluru, Chennai and Amritsar. 

Nature of the attack 

GPS spoofing, which consists of sending fake satellite signals to navigation receivers and makes the aircraft systems believe that it is at a different location and altitude. A number of flights to Runway 10 at the Delhi airport reported being misled by false GPS signals in the midst of GPS approach routines. A number of aircraft suffered navigation systems falsely displaying their locations as far as 60 nautical miles from their actual position, causing some to divert to nearby cities. 

While highlighting the gravity of these attacks, Minister Naidu said, that “no incidents of flight operations being interfered or flights being delayed on account of GPS spoofing were reported.” The aviation regulators were forced to invoke contingency procedures for GPS-spoofed flights, which did not affect scheduled operations on other runways, equipped with more traditional navigational aids. The seamless operations were attributed to India’s strong backup systems and safety procedures in place.

In addition, India operates a Minimum Operating Network (MON) of ground-based navigation and surveillance systems as a backup in the event of disruption of space-based systems. Such a fail-safe model, applied all over the world among satellite navigation and communication providers, ensures the continued availability of traditional navigation means over the skies, when the reception of signals from satellites is lost. The use of the MON enable the aviation community to keep the skies open even in the face of sophisticated cyber attacks on GPS. 

Government response and investigation 

Earlier, the DGCA had issued advisories on GNSS signal jamming and spoofing in the airspace on 24 November 2023, and subsequently Standard Operating Procedure (SOP) guidelines on 10 November 2025 for reporting in real-time GPS jamming and spoofing incidents. Post the recent attacks, Airports Authority of India (AAI) has approached Wireless Monitoring Organization (WMO) to trace the source of interference/spoofing. During a high-level meeting, the WMO was directed to mobilize additional resources to pinpoint the spoofing source based on approximate location details shared by DGCA and AAI. 

Minister Naidu believes that the threats are global, and now more frequently in the form of ransomware and malware attacks targeting aviation. As a result, AAI is rolling out state-of-the-art cybersecurity solutions for IT networks and infrastructure in lieu with the directions from the National Critical Information Infrastructure Protection Centre (NCIIPC) under the Ministry of Home Affairs and the Indian Computer Emergency Response Team (CERT-In). India is also actively engaging in global platforms for learning and sharing of most recent best practices, tools, and techniques to enable real time implementation of security measures.

Cloudflare Blocks Largest DDoS Attack in History as Global Cyber Threats Surge

Cloudflare announced on Wednesday that it has detected and stopped the largest distributed denial of service (DDoS) attack ever recorded. 

The attack peaked at 29.7 terabits per second and lasted 69 seconds. The company said the traffic came from a botnet-for-hire called AISURU, which has been behind several extreme DDoS incidents over the past year. Cloudflare did not reveal the name of the targeted organization. 

AISURU has repeatedly targeted telecommunication companies, gaming platforms, hosting providers and financial services. 

Cloudflare said it also blocked another massive attack from the same botnet that reached 14.1 billion packets per second. Security researchers estimate that AISURU is powered by one to four million infected devices across the world. 

According to Cloudflare, the record-breaking event was a UDP carpet bombing attack that hit around 15,000 ports per second. The attackers randomised packet properties to get past defences, but Cloudflare’s automated systems detected and neutralised the traffic. Cloudflare has recorded 2,867 AISURU attacks since the beginning of 2025. 

Out of these, 1,304 hyper volumetric attacks happened in the third quarter of this year alone. In total, the company blocked 8.3 million DDoS attacks during the same period. That number is 15 percent higher than the previous quarter and 40 percent higher than the same period last year. 

So far in 2025, Cloudflare has mitigated 36.2 million DDoS attacks, and the year is not yet over. The company highlighted a rapid increase in network layer attacks, which now make up 71 percent of all recorded attacks. 

Meanwhile, HTTP DDoS attacks declined in comparison. The report also shows major changes in the global DDoS landscape. The number of attacks that went above 100 million packets per second jumped by 189 percent quarter over quarter. In addition, 1,304 attacks exceeded one terabit per second. 

Cloudflare noted that most attacks last for less than 10 minutes, which leaves very little time for manual intervention and can still cause long service disruptions. 

The list of attack sources is dominated by Asia. Indonesia has remained the world’s biggest source of DDoS attacks for an entire year, followed by other locations such as Thailand, Bangladesh, Vietnam, India, Hong Kong and Singapore. Ecuador, Russia and Ukraine make up the remaining top ten. 

Several industries have seen major increases in targeting. Attacks against the mining, minerals and metals sector rose sharply and pushed it to the 49th most attacked industry worldwide. The automotive industry experienced the largest jump and is now the sixth most attacked. 

DDoS attacks targeting artificial intelligence companies rose by 347 percent in September alone. Across all sectors, information technology and services faced the most attacks. Telecommunications, gambling, gaming and internet services were also among the hardest hit. 

The most attacked countries this year include China, Turkey, Germany, Brazil, the United States and Russia. Cloudflare said the scale and sophistication of current DDoS activity marks a turning point for global cybersecurity. 

The company warned that many organizations are struggling to keep up with attackers who now operate with far more power and speed than ever before.

AI-Assisted Cyberattacks Signal a Shift in Modern Threat Strategies and Defense Models

 

A new wave of cyberattacks is using large language models as an offensive tool, according to recent reporting from Anthropic and Oligo Security. Both groups said hackers used jailbroken LLMs-some capable of writing code and conducting autonomous reasoning-to conduct real-world attack campaigns. While the development is alarming, cybersecurity researchers had already anticipated such advancements. 

Earlier this year, a group at Cornell University published research predicting that cybercriminals would eventually use AI to automate hacking at scale. The evolution is consistent with a recurring theme in technology history: Tools designed for productivity or innovation inevitably become dual-use. Any number of examples-from drones to commercial aircraft to even Alfred Nobel's invention of dynamite-demonstrate how innovation often carries unintended consequences. 

The biggest implication of it all in cybersecurity is that LLMs today finally allow attackers to scale and personalize their operations simultaneously. In the past, cybercriminals were mostly forced to choose between highly targeted efforts that required manual work or broad, indiscriminate attacks with limited sophistication. 

Generative AI removes this trade-off, allowing attackers to run tailored campaigns against many targets at once, all with minimal input. In Anthropic's reported case, attackers initially provided instructions on ways to bypass its model safeguards, after which the LLM autonomously generated malicious output and conducted attacks against dozens of organizations. Similarly, Oligo Security's findings document a botnet powered by AI-generated code, first exploiting an AI infrastructure tool called Ray and then extending its activity by mining cryptocurrency and scanning for new targets. 

Traditional defenses, including risk-based prioritization models, may become less effective within this new threat landscape. These models depend upon the assumption that attackers will strategically select targets based upon value and feasibility. Automation collapses the cost of producing custom attacks such that attackers are no longer forced to prioritize. That shift erases one of the few natural advantages defenders had. 

Complicating matters further, defenders must weigh operational impact when making decisions about whether to implement a security fix. In many environments, a mitigation that disrupts legitimate activity poses its own risk and may be deferred, leaving exploitable weaknesses in place. Despite this shift, experts believe AI can also play a crucial role in defense. The future could be tied to automated mitigations capable of assessing risks and applying fixes dynamically, rather than relying on human intervention.

In some cases, AI might decide that restrictions should narrowly apply to certain users; in other cases, it may recommend immediate enforcement across the board. While the attackers have momentum today, cybersecurity experts believe the same automation that today enables large-scale attacks could strengthen defenses if it is deployed strategically.

Beer Firm Asahi Not Entertaining Threat Actors After Cyberattack


Asahi denies ransom payment 

Japanese beer giant Asahi said that it didn't receive any particular ransom demand from threat actors responsible for an advanced and sophisticated cyberattack that could have exposed the data of more than two million people. 

About the attack

CEO Atsushi Katsuki in a press conference said that the company had not been in touch with the threat actors. But Asahi has delayed the release of financial results. Even if the company received a ransom demand, it would not have paid, Katsuki said. Asahi Super Dry is one of Japan's most popular beers. Asahi suffered a cyberattack on 29th September. However, the company clarified on October 3 that it was hit by a ransomware attack.

Attack tactic 

In such incidents, threat actors typically use malicious software to encrypt the target's systems and then ask ransom for providing encryption keys to run the systems again.

Asahi said threat actors could have hacked or stolen identity data like phone numbers and names of around two million people- employees, customers and families.

Qilin gang believed to be responsible 

The firm didn't disclose details of the attacker at the conference. Later, it told AFP via mail that experts hinted towards a high chance of attack by hacking group Qilin. The gang issued a statement that the Japanese media understood as a claim of responsibility. Commenting on the situation, 

Katsuki said the firm thought it had taken needed measures to prevent such an incident. "But this attack was beyond our imagination. It was a sophisticated and cunning attack," Katsuki said. 

Impact on Asahi business 

Interestingly, Asahi delayed the release of third-quarter earnings and recently said that the annual financial results had also been delayed. "These and further information on the impact of the hack on overall corporate performance will be disclosed as soon as possible once the systems have been restored and the relevant data confirmed," the firm said.

The product supply hasn't been affected. Shipments will resume in stages while systems recover. "We apologise for the continued inconvenience and appreciate your understanding," Asahi said.

London Councils Hit by Cyberattacks Disrupting Public Services and Raising Security Concerns

 

Multiple local authorities across London have been hit by cyber incidents affecting operations and public services, according to reports emerging overnight. The attacks have disrupted essential council functions, including communication systems and digital access, prompting heightened concern among officials and cybersecurity experts. 

Initial reporting from the BBC confirmed that several councils experienced operational setbacks due to the attack. Hackney Council elevated its cybersecurity alert level to the highest classification, while Westminster City Council acknowledged challenges with public contact systems. The Royal Borough of Kensington and Chelsea also confirmed an active investigation into the breach. Internal messages seen by the Local Democracy Reporting Service reportedly advised employees to follow emergency cybersecurity protocols and noted that at least one affected council temporarily shut down its networks to prevent further compromise. 

In a public statement, Kensington and Chelsea Council confirmed the incident and stated that it was working alongside cybersecurity consultants and the U.K. National Cyber Security Centre to secure systems and restore functionality. The council also confirmed that it shares certain IT infrastructure with Westminster City Council, and both organisations are coordinating their response. However, Hackney Council later clarified that it was not impacted by this specific incident, describing reports linking it to the breach as inaccurate. 

The council stated that its systems remain operational and emphasised that staff have been reminded of ongoing data protection responsibilities. Mayor of London Sadiq Khan commented that cybercriminals are increasingly targeting public-sector systems and stressed the importance of improving resilience across government infrastructure. Security specialists have also issued warnings following the incident. Dray Agha, senior director of security operations at Huntress, described the attack as a stark example of the risks associated with shared government IT frameworks. Agha argued that while shared digital systems may be cost-efficient, they can significantly increase exposure if an attacker gains access to one connected organisation. 

Rebecca Moody, head of data research at Comparitech, said the disruption aligns with common indicators of ransomware activity, noting both operational outages and possible data exposure. She added that government bodies remain among the most frequent targets of cyber extortion, with global data showing 174 confirmed attacks on government institutions so far in 2025, affecting more than 780,000 records and averaging ransom demands of roughly $2.5 million. Ian Nicholson, head of incident response at Pentest People, warned that the consequences extend beyond system outages. 

Councils hold highly sensitive and regulated personal information, he noted, and cyber incidents affecting the public sector can directly impact citizen-facing services, particularly those tied to social care and emergency support. As investigations continue, affected authorities have stated that their primary focus remains on safeguarding resident data, restoring services, and preventing further disruption.
