North Korean Malware Targets Mac Users in Crypto Sector via Calendly and Telegram

 

Cybersecurity researchers have identified a sophisticated malware campaign targeting Mac users involved in blockchain technologies. According to SentinelLabs, the attack has been linked to North Korean threat actors, based on an investigation conducted by Huntabil.IT. 

The attack method is designed to appear as a legitimate interaction. Victims are contacted via Telegram, where the attacker impersonates a known associate or business contact. They are then sent a meeting invite using Calendly, a widely-used scheduling platform. The Calendly message includes a link that falsely claims to be a “Zoom SDK update script.” Instead, this link downloads malware specifically designed to infiltrate macOS systems. 

The malware uses a combination of AppleScript, C++, and the Nim programming language to evade detection. This mix is relatively novel, especially the use of Nim in macOS attacks. Once installed, the malware gathers a broad range of data from the infected device. This includes system information, browser activity, and chat logs from Telegram. It also attempts to extract login credentials, macOS Keychain passwords, and data stored in browsers like Arc, Brave, Firefox, Chrome, and Microsoft Edge. Interestingly, Safari does not appear to be among the targeted applications. 

While the campaign focuses primarily on a niche audience—Mac users engaged in crypto-related work who use Calendly and Telegram—SentinelLabs warns that the tactics employed could signal broader threats on the horizon. The use of obscure programming combinations to bypass security measures is a red flag for potential future campaigns targeting a wider user base. 

To safeguard against such malware, users are advised to avoid downloading software from public code repositories or unofficial websites. While the Mac App Store is considered the safest source for macOS applications, software downloaded directly from reputable developers’ websites is generally secure. Users who rely on pirated or cracked applications remain at significantly higher risk of infection. 

Cyber hygiene remains essential. Never click on suspicious links received via email, text, or social platforms, especially from unknown or unverified sources. Always verify URLs by copying and pasting them into a text editor to see their true destination before visiting. It’s also crucial to install macOS security updates promptly, as these patches address known vulnerabilities.  

For additional protection, consider using trusted antivirus software. Guides from Macworld suggest that while macOS has built-in security, third-party tools like Intego can offer enhanced protection. As malware campaigns evolve in complexity and scope, staying vigilant is the best defense.

Why Exploring the Dark Web Can Lead to Legal Trouble, Malware, and Emotional Harm

 

Venturing into the dark web may seem intriguing to some, but even well-intentioned users are exposed to significant risks. While many people associate the dark web with illegal activity, they may not realize that just browsing these hidden spaces can lead to serious consequences, both legal and emotional. Unlike the regulated surface web, the dark web operates with little to no oversight, which makes stumbling across disturbing or illicit content dangerously easy.

A simple click on an unfamiliar link can redirect users to graphic or illegal material. This content is not always clearly labeled, and visitors may not realize what they’re seeing until it’s too late. In several jurisdictions, merely viewing certain types of content—whether or not you meant to—can have legal repercussions. Users may also experience lasting psychological impact after encountering explicit or violent media. Reports of anxiety, stress, and trauma are not uncommon, even among casual users who were simply exploring out of curiosity.  

Malware, spyware, and keyloggers are often disguised as legitimate downloads or hidden in popular tools. Many websites host dangerous files designed to infect your device as soon as they are opened. Even privacy-focused platforms like Tor can’t fully shield users from malicious code or phishing attempts, especially when browsers are misconfigured or when users interact with suspicious content. 

Technical errors—like enabling JavaScript, resizing your browser window, or leaking DNS requests—can also expose your identity, even if you’re using encrypted tools. Cybersecurity professionals warn that mistakes like these are common and can be exploited by attackers or even government agencies. Law enforcement agencies actively monitor known dark web nodes and can use advanced techniques to track user behavior, collect metadata, and build profiles for surveillance. 

Additionally, scammers thrive in the anonymous environment of the dark web. Fake login portals, spoofed forums, and crypto wallet traps are rampant. And if you’re scammed, there’s little you can do—there are no refund options or customer service teams to help you recover lost funds or data. 

The dark web is often underestimated, constant exposure to unsettling content and the need to stay hyper-aware of threats can wear down a person’s sense of safety and trust. In many cases, the psychological damage can linger far longer than the browsing session itself. 

In short, exploring the dark web without a thorough understanding of the dangers can backfire. It’s a space where curiosity offers no protection, and the consequences—ranging from infections and identity loss to legal charges and emotional distress—can affect even the most cautious users.

Lostkeys Malware: Russian Group Coldriver Targets Western Officials in Espionage Campaign

 

A new wave of cyber espionage has emerged, with Russian hackers deploying a sophisticated malware strain known as “Lostkeys” to infiltrate the systems of Western officials, journalists, and NGOs. According to researchers from Google’s Threat Intelligence Group, the malware is linked to Coldriver, also known as UNC4057, Star Blizzard, or Callisto—a threat actor believed to be part of Russia’s Federal Security Service (FSB), the successor to the KGB. 

Coldriver has traditionally been involved in phishing operations to steal credentials, but the emergence of Lostkeys demonstrates a significant leap in their cyber capabilities. Lostkeys appears to mark a shift in strategy for the group, moving beyond phishing and into deeper system infiltration. The malware is deployed in a targeted manner, reserved for high-value individuals such as political advisors, think tank members, journalists, and people with known connections to Ukraine.

Activity related to Lostkeys was observed by Google in the early months of 2024—specifically January, March, and April—with evidence suggesting its use might have started as far back as December 2023. The attack begins with a deceptive Captcha page, tricking victims into copying a malicious PowerShell script into the Windows Run dialog. This method, known as “ClickFix,” bypasses typical security filters and exploits user behavior rather than software vulnerabilities. 

Once executed, the script connects to a command-and-control server, downloading a series of payloads uniquely tailored to each victim. In an effort to avoid detection, the malware includes anti-sandbox measures. During the second stage of infection, the script checks the screen resolution of the host machine and halts if it matches known virtual machine environments used by analysts and cybersecurity researchers. If the device passes this check, the malware proceeds to the final stage—a Visual Basic Script that steals data, including specific file types, system details, and active processes. These are exfiltrated back to the attackers using an encoded system that applies a unique two-key substitution cipher for each infected machine. 

Lostkeys appears to be a more refined successor to a previous malware strain known as Spica, which Coldriver also deployed in 2024. While both strains focus on data exfiltration, Lostkeys features a more intricate delivery system and improved obfuscation techniques. Some earlier samples of Lostkeys mimicked legitimate software like Maltego and used executable files instead of PowerShell, though Google has not confirmed if these instances were part of the same campaign or the work of a different threat actor reusing Coldriver’s tactics. 

This development highlights an alarming evolution in state-backed cyber operations, where advanced social engineering and stealth techniques are being increasingly used to infiltrate high-profile targets. As geopolitical tensions persist, the risks posed by such targeted cyber espionage campaigns are expected to grow.

Understanding Cybersquatting: How Malicious Domains Threaten Brands and Individuals

 

Cybersquatting remains a persistent threat in the digital landscape, targeting businesses, individuals, and public figures alike. This deceptive practice involves registering domain names that closely resemble those of legitimate brands or individuals, often with malicious intent. Despite rising awareness and improved security measures, cybersquatting continues to flourish. According to the World Intellectual Property Organization (WIPO), nearly 6,200 domain disputes related to cybersquatting were filed with its Arbitration and Mediation Center in 2024, indicating the scale of the problem. 

Typically, cybersquatters aim to exploit the reputation of an existing brand by acquiring a domain that looks similar to the original. They might register a domain before a business secures it, or take advantage of minor spelling variations that are easily overlooked by users. This allows them to mislead consumers, drive traffic to fraudulent websites, or sell the domain back to the rightful owner at a premium. In more dangerous scenarios, these domains are used to host phishing scams, distribute malware, or promote counterfeit products. One common technique employed by cybersquatters is typosquatting, where domains are registered with intentional misspellings or typographical errors. Unsuspecting users who mistype a URL may unknowingly land on malicious sites. 

A notable example occurred in 2006 when a domain resembling “Google.com” was used to trick visitors into installing fake antivirus software. Another tactic involves registering domains tied to celebrities or public figures, often with the intent to damage reputations or spread spam. A high-profile case involved Madonna, who successfully reclaimed a domain bearing her name that was being used to host adult content. Some cybersquatters engage in identity-based attacks, closely imitating official company domains to carry out fraud or data theft. For example, Dell once had to legally pursue entities that had registered over 1,100 domains using names resembling its brand. Others use a tactic called reverse cybersquatting, where they first register a business and then secure the corresponding domain, falsely claiming legitimacy to obstruct the actual brand’s efforts to recover it.

In another method, known as domain name warehousing, attackers monitor expiring domains and quickly register them if the original owner forgets to renew. In one case, a former campaign domain linked to politician Nigel Farage was redirected to an opponent’s site as a form of protest. While legal frameworks exist to combat cybersquatting, enforcement can be complex. In the United States, the Anti-Cybersquatting Consumer Protection Act (ACPA) empowers victims to take legal action and potentially reclaim their domains along with financial damages. 

The European Union Intellectual Property Office (EUIPO) also provides mechanisms to enforce trademark rights in domain disputes. Additionally, WIPO can facilitate domain transfers when bad faith registration is proven. Despite these protections, prevention remains key. Organizations are encouraged to register not only their primary domains but also common misspellings, different extensions, and regional variations to minimize the risk of cybersquatters exploiting their identity.

FBI Warns Consumers to Replace Outdated Routers Hijacked by TheMoon Malware

 

The FBI has issued an urgent warning to American consumers and businesses: replace outdated internet routers immediately or risk becoming an unwitting accomplice in cybercrime. According to the agency, cybercriminals are actively targeting “end-of-life” routers—older models that no longer receive security updates from manufacturers—and infecting them with a sophisticated variant of TheMoon malware. Once compromised, these routers are hijacked and repurposed as proxy servers that enable criminals to mask their identities while conducting illegal activities online. 

These include financial fraud, dark web transactions, and cyberattacks, all executed through unsuspecting users’ networks. Because these routers lack updated firmware and security patches, they are especially vulnerable to remote infiltration and control. TheMoon malware, which first emerged in 2014, has evolved into a more potent threat. It now scans for open ports and installs itself without requiring a password. Once embedded, it silently operates in the background, routing illicit activity and potentially spreading to other devices within the network. The malware’s stealthy behavior often leaves users unaware that their home or business network has become part of a criminal infrastructure. 

The FBI specifically warned that routers manufactured in 2010 or earlier are particularly at risk—especially if features like remote administration are still enabled. Older Linksys models such as E1200, E2500, E1000, E4200, E1500, E300, E3200, WRT320N, E1550, WRT610N, E100, M10, and WRT310N are listed among the most vulnerable devices. Signs of a compromised router may include overheating, unexplained changes to settings, or erratic internet connectivity. In many cases, users may not even realize their equipment is outdated, making them easy targets for attackers seeking anonymous access to the web. 

To defend against these threats, the FBI strongly advises replacing unsupported routers with modern, secure models. Users should also disable remote access functions, install the latest security patches, and use complex, unique passwords to further protect their networks. If anyone suspects their router has been hijacked or detects suspicious activity, they are encouraged to file a report with the FBI’s Internet Crime Complaint Center (IC3). 

As cybercriminals become more innovative, relying on outdated technology increases exposure to serious digital threats. This latest alert is a stark reminder that cybersecurity begins at home—and that even something as common as a router can become a gateway for criminal exploitation if not properly secured.

Malware Hides in Fake PDF to DOCX Converters to Target Crypto Wallets and Steal Data

 

Cybercriminals have launched a deceptive malware campaign that disguises itself as online file converters, specifically targeting users searching for PDF to DOCX tools. This scheme uses convincing replicas of popular converter sites to execute hidden PowerShell scripts and deploy a Remote Access Trojan designed to steal sensitive data, including cryptocurrency wallets and browser credentials. 

Security researchers at CloudSEK investigated the threat following an FBI warning issued last month. They discovered that attackers are using a malware variant called Arechclient2, derived from the known info-stealing family SectopRAT. The campaign works by luring unsuspecting users to malicious websites that impersonate legitimate services like PDFCandy. These fake platforms feature realistic user interfaces, including loading indicators and CAPTCHA forms, to establish trust before delivering the malware. When a user attempts to convert a file, they are redirected multiple times before receiving a ZIP archive named “adobe.zip.” Inside the archive is the malicious payload, which installs the Arechclient2 Remote Access Trojan. 

This malware, active since 2019, is capable of scanning for browser-saved credentials, cryptocurrency wallet seed phrases, and even tapping into decentralized finance tools via Web3 APIs. Stephen Ajayi, Technical Lead at Hacken’s Dapp Audit division, explained that the malware not only lifts crypto wallet details but also enables attackers to “ghost-drain” assets after a transaction approval—making it especially dangerous for Web3 users. CloudSEK advises users to avoid downloading tools from unofficial or unverified sites, particularly free online file converters. Instead, they recommend trusted offline software or tools from official sources. 

They also warn that malicious files often disguise themselves using harmless-looking extensions, so users should inspect file types carefully and use reliable antivirus or endpoint detection software. Ajayi emphasized the importance of a proactive security mindset. “In cybersecurity, trust should be earned. Assume nothing is safe by default,” he said. He advised crypto users and general web users alike to adopt a zero-trust approach, keep their security tools updated, and monitor systems for unusual activity such as rogue msbuild.exe processes. 

As threats like these evolve, staying vigilant, maintaining strong security protocols, and preparing for worst-case scenarios are critical steps for avoiding compromise. Regular training and a well-tested incident response plan remain key defenses against such deceptive but damaging attacks.

SK Telecom Malware Attack Exposes USIM Data in South Korea

 

SK Telecom, South Korea’s top mobile carrier, has disclosed a security incident involving a malware infection that exposed sensitive information tied to users’ Universal Subscriber Identity Modules (USIMs). The breach was detected on the night of April 19, 2025, during the weekend when many companies operate with reduced cybersecurity staffing. 

With nearly half of South Korea’s mobile market share and around 34 million subscribers, SK Telecom holds a crucial position in the country’s telecommunications sector. In an official statement, the company explained that malware had infiltrated parts of its network, prompting immediate action to contain the threat. 

The affected systems were isolated swiftly, and the malicious software was removed. So far, SK Telecom has stated there is no confirmed misuse of customer data linked to this breach. This was reported to the Korea Internet & Security Agency (KISA) on April 20, and to the Personal Information Protection Commission. 
Investigations are ongoing to determine how the attackers gained access and the extent of the data exposed. USIM cards store essential data such as International Mobile Subscriber Identity (IMSI) numbers, phone numbers (MSISDN), encryption keys for network authentication, and sometimes even stored contacts or text messages. Unauthorized access to this information could enable cybercriminals to conduct targeted surveillance, track users’ locations, or perform SIM-swapping attacks that could compromise online accounts and digital assets. 

In response, SK Telecom has strengthened security around USIM card management, increasing checks on SIM card replacement activities and monitoring authentication processes for suspicious behavior. Accounts showing irregular activities could face automatic suspension to prevent potential fraud. Additionally, the carrier is advising customers to activate their USIM protection service, a preventive measure that restricts unauthorized SIM swaps, adding extra protection to user accounts. 

A hacking group is yet to claim responsibility for the breach. SK Telecom emphasized that while the malware was neutralized quickly, they remain vigilant and are working closely with cybersecurity authorities to uncover more details about the intrusion and enhance future protections. 

This breach highlights ongoing risks faced by large mobile operators, especially during periods when cyber defenses might be less robust. It also underscores the critical need for mobile carriers to adopt continuous security monitoring and proactive measures to protect customer data from emerging threats. 

As investigations continue, SK Telecom has committed to updating customers and regulators about any new findings or developments related to the incident.

Windows CLFS Zero-Day CVE-2025-29824 Exploited by Ransomware Group Storm-2460

 

A newly disclosed Windows zero-day vulnerability, tracked as CVE-2025-29824, is being actively exploited in cyberattacks to deliver ransomware, Microsoft has warned. This flaw affects the Windows Common Log File System (CLFS) driver and enables local privilege escalation—a method often used by attackers after gaining initial access. 

Microsoft’s Threat Intelligence and Security Response teams revealed that the bug is classified as a “use-after-free” vulnerability with a severity score of 7.8. While attackers need to compromise a system before they can exploit this flaw, it remains highly valuable in ransomware operations. Cybercriminals often rely on these types of vulnerabilities to turn a limited foothold into full administrative control across networks. 

The cybercrime group currently leveraging this zero-day is known as Storm-2460. Microsoft reports that the group is using the exploit to deploy a custom backdoor named PipeMagic, which in turn facilitates the installation of RansomEXX ransomware—a variant not commonly observed but still capable of serious disruption. So far, Storm-2460 has targeted organizations in industries such as IT, finance, and retail, with victims located in countries including the United States, Spain, Saudi Arabia, and Venezuela. 

Microsoft emphasized that the number of known cases remains small, but the sophistication of the exploit is concerning. This attack is notable for being part of a “post-compromise” campaign, meaning the attacker already has a presence within the system before using the flaw. These types of exploits are frequently used to escalate privileges and move laterally within a network, eventually leading to broader ransomware deployment. Microsoft issued a security advisory for CVE-2025-29824 on April 8 and urged organizations to install updates immediately. Failure to do so could leave critical systems vulnerable to privilege escalation and full network compromise. 

To mitigate risk, Microsoft advises businesses to prioritize patch management, restrict unnecessary administrative privileges, and closely monitor for unusual behavior across endpoints. Cybersecurity teams are also encouraged to review logs for any indicators of compromise related to PipeMagic or RansomEXX. As ransomware tactics continue to evolve, the exploitation of vulnerabilities like CVE-2025-29824 reinforces the need for proactive defense strategies and rapid incident response protocols.

WhatsApp Windows Vulnerability CVE-2025-30401 Could Let Hackers Deliver Malware via Fake Images

 

Meta has issued a high-priority warning about a critical vulnerability in the Windows version of WhatsApp, tracked as CVE-2025-30401, which could be exploited to deliver malware under the guise of image files. This flaw affects WhatsApp versions prior to 2.2450.6 and could expose users to phishing, ransomware, or remote code execution attacks. The issue lies in how WhatsApp handles file attachments on Windows. 

The platform displays files based on their MIME type but opens them according to the true file extension. This inconsistency creates a dangerous opportunity for hackers: they can disguise executable files as harmless-looking images like .jpeg files. When a user manually opens the file within WhatsApp, they could unknowingly launch a .exe file containing malicious code. Meta’s disclosure arrives just as new data from online bank Revolut reveals that WhatsApp was the source of one in five online scams in the UK during 2024, with scam attempts growing by 67% between June and December. 

Cybersecurity experts warn that WhatsApp’s broad reach and user familiarity make it a prime target for exploitation. Adam Pilton, senior cybersecurity consultant at CyberSmart, cautioned that this vulnerability is especially dangerous in group chats. “If a cybercriminal shares the malicious file in a trusted group or through a mutual contact, anyone in that group might unknowingly execute malware just by opening what looks like a regular image,” he explained. 

Martin Kraemer, a security awareness advocate at KnowBe4, highlighted the platform’s deep integration into daily routines—from casual chats to job applications. “WhatsApp’s widespread use means users have developed a level of trust and automation that attackers exploit. This vulnerability must not be underestimated,” Kraemer said. Until users update to the latest version, experts urge WhatsApp users to treat the app like email—avoid opening unexpected attachments, especially from unknown senders or new contacts. 

The good news is that Meta has already issued a fix, and updating the app resolves the vulnerability. Pilton emphasized the importance of patch management, noting, “Cybercriminals will always seek to exploit software flaws, and providers will keep issuing patches. Keeping your software updated is the simplest and most effective protection.” For now, users should update WhatsApp for Windows immediately to mitigate the risk posed by CVE-2025-30401 and remain cautious with all incoming files.

Cyber Security Extension Malware Detection Malwares Marketplace Microsoft Microsoft security Ransomwares Security Flaws

Ransomware Found in VSCode Extensions Raises Concerns Over Microsoft’s Security Review

 

Cybersecurity experts have discovered ransomware hidden within two Visual Studio Code (VSCode) Marketplace extensions, raising concerns about Microsoft’s ability to detect malicious software in its platform. The compromised extensions, named “ahban.shiba” and “ahban.cychelloworld,” were downloaded by users before security researchers flagged them and they were subsequently removed. 

Despite Microsoft’s security measures, the extensions remained publicly accessible for a significant period, highlighting potential gaps in the company’s review process. The “ahban.cychelloworld” extension was first uploaded on October 27, 2024, followed by “ahban.shiba” on February 17, 2025. The VSCode Marketplace, designed to provide developers with additional tools for Microsoft’s popular coding platform, has come under scrutiny for failing to identify these threats. 

Researchers at ReversingLabs determined that both extensions included a PowerShell script that connected to a remote Amazon Web Services (AWS) server to download further malicious code. This secondary payload functioned as ransomware, though evidence suggests it was still in a testing phase. 

Unlike traditional ransomware that encrypts entire systems, this malware specifically targeted files stored in C:\users%username%\Desktop\testShiba.  Once the encryption was complete, victims received a Windows notification stating: “Your files have been encrypted. Pay 1 ShibaCoin to ShibaWallet to recover them.” However, no further instructions or payment details were provided, suggesting the malware was not yet fully developed.  

Although Microsoft eventually removed the extensions, security researcher Italy Kruk from ExtensionTotal disclosed that their automated detection system had identified the malicious code much earlier. Kruk stated that they had alerted Microsoft about the issue but received no response. Further analysis revealed that the initial version of “ahban.cychelloworld” was clean, but the ransomware was introduced in version 0.0.2, which was released on November 24, 2024. ExtensionTotal flagged this version to Microsoft on November 25, yet the extension remained available for months. 

During this time, five more versions were uploaded, all containing the same ransomware. This case has intensified concerns about Microsoft’s ability to monitor third-party extensions effectively. The security lapse within the VSCode Marketplace highlights the risk developers face when downloading extensions, even from official sources. Microsoft has previously faced criticism for both slow responses to security threats and for mistakenly removing non-malicious extensions. 

A notable example involved two popular VSCode themes, ‘Material Theme – Free’ and ‘Material Theme Icons – Free,’ which were taken down due to suspected obfuscated JavaScript. However, after further review, Microsoft determined the extensions were safe, reinstated them, and apologized, promising improvements to its security screening process. The presence of ransomware in widely used developer tools underscores the need for stronger security measures. Developers must stay cautious, regularly update security protocols, and carefully evaluate third-party extensions before installing them, even when they come from official platforms like the VSCode Marketplace.

Arcane Malware Steals VPN, Gaming, and Messaging Credentials in New Cyber Threat

 

A newly identified malware strain, Arcane, is making headlines for its ability to steal a vast range of user data. This malicious software infiltrates systems to extract sensitive credentials from VPN services, gaming platforms, messaging apps, and web browsers. Since its emergence in late 2024, Arcane has undergone several modifications, increasing its effectiveness and expanding its reach. 

Unlike other cyber threats with long-established histories, Arcane is not linked to previous malware versions carrying a similar name. Analysts at Kaspersky have observed that the malware primarily affects users in Russia, Belarus, and Kazakhstan. This is an unusual pattern, as many Russian-based cybercriminal groups tend to avoid targeting their home region to steer clear of legal consequences. 

Additionally, communications linked to Arcane’s operators suggest that they are Russian-speaking, reinforcing its likely origin. The malware spreads through deceptive content on YouTube, where cybercriminals post videos promoting game cheats and cracked software. Viewers are enticed into downloading files that appear legitimate but contain hidden malware. Once opened, these files initiate a process that installs Arcane while simultaneously bypassing Windows security settings. 

This allows the malware to operate undetected, giving hackers access to private information. Prior to Arcane, the same group used a different infostealer known as VGS, a modified version of an older trojan. However, since November 2024, they have shifted to distributing Arcane, incorporating a new tool called ArcanaLoader. This fake installer claims to provide free access to premium game software but instead delivers the malware. 

It has been heavily marketed on YouTube and Discord, with its creators even offering financial incentives to content creators for promoting it. Arcane stands out because of its ability to extract detailed system data and compromise various applications. It collects hardware specifications, scans installed software, and retrieves login credentials from VPN clients, communication platforms, email services, gaming accounts, and cryptocurrency wallets. Additionally, the malware captures screenshots, which can expose confidential information visible on the victim’s screen. 

Though Arcane is currently targeting specific regions, its rapid evolution suggests it could soon expand to a broader audience. Cybersecurity experts warn that malware of this nature can lead to financial theft, identity fraud, and further cyberattacks. Once infected, victims must reset all passwords, secure compromised accounts, and ensure their systems are thoroughly cleaned. 

To reduce the risk of infection, users are advised to be cautious when downloading third-party software, especially from unverified sources. Game cheats and pirated programs often serve as delivery methods for malicious software, making them a significant security threat. Avoiding these downloads altogether is the safest approach to protecting personal information.

The Growing Threat of Infostealer Malware: What You Need to Know

 

Infostealer malware is becoming one of the most alarming cybersecurity threats, silently stealing sensitive data from individuals and organizations. This type of malware operates stealthily, often going undetected for long periods while extracting valuable information such as login credentials, financial details, and personal data. As cybercriminals refine their tactics, infostealer attacks have become more frequent and sophisticated, making it crucial for users to stay informed and take preventive measures. 

A significant reason for concern is the sheer scale of data theft caused by infostealers. In 2024 alone, security firm KELA reported that infostealer malware was responsible for leaking 3.9 billion passwords and infecting over 4.3 million devices worldwide. Similarly, Huntress’ 2025 Cyber Threat Report revealed that these threats accounted for 25% of all cyberattacks in the previous year. This data highlights the growing reliance of cybercriminals on infostealers as an effective method of gathering personal and corporate information for financial gain. 

Infostealers operate by quietly collecting various forms of sensitive data. This includes login credentials, browser cookies, email conversations, banking details, and even clipboard content. Some variants incorporate keylogging capabilities to capture every keystroke a victim types, while others take screenshots or exfiltrate files. Cybercriminals often use the stolen data for identity theft, unauthorized financial transactions, and large-scale corporate breaches. Because these attacks do not immediately disrupt a victim’s system, they are harder to detect, allowing attackers to extract vast amounts of information over time. Hackers distribute infostealer malware through multiple channels, making it a widespread threat. 

Phishing emails remain one of the most common methods, tricking victims into downloading infected attachments or clicking malicious links. However, attackers also embed infostealers in pirated software, fake browser extensions, and even legitimate platforms. For example, in February 2025, a game called PirateFi was uploaded to Steam and later found to contain infostealer malware, compromising hundreds of devices before it was removed. Social media platforms, such as YouTube and LinkedIn, are also being exploited to spread malicious files disguised as helpful tools or software updates. 

Beyond stealing data, infostealers serve as an entry point for larger cyberattacks. Hackers often use stolen credentials to gain unauthorized access to corporate networks, paving the way for ransomware attacks, espionage, and large-scale financial fraud. Once inside a system, attackers can escalate their access, install additional malware, and compromise more critical assets. This makes infostealer infections not just an individual threat but a major risk to businesses and entire industries.  

The prevalence of infostealer malware is expected to grow, with attackers leveraging AI to improve phishing campaigns and developing more advanced evasion techniques. According to Check Point’s 2025 Cybersecurity Report, infostealer infections surged by 58% globally, with Europe, the Middle East, and Africa experiencing some of the highest increases. The SYS01 InfoStealer campaign, for instance, impacted millions across multiple continents, showing how widespread the issue has become. 

To mitigate the risks of infostealer malware, individuals and organizations must adopt strong security practices. This includes using reliable antivirus software, enabling multi-factor authentication (MFA), and avoiding downloads from untrusted sources. Regularly updating software and monitoring network activity can also help detect and prevent infections. Given the growing threat, cybersecurity awareness and proactive defense strategies are more important than ever.

CISA & FBI CISA advisory Cyber Attacks Malwares Medusa Attacks Medusa Ransomware RaaS ransomware attacks ransomware-as-a-service (RaaS) Ransomwares

Medusa Ransomware Attacks: CISA, FBI, and MS-ISAC Issue #StopRansomware Advisory

 

The Cybersecurity and Infrastructure Security Agency (CISA), in partnership with the FBI and the Multi-State Information Sharing and Analysis Center (MS-ISAC), has issued a #StopRansomware advisory, warning organizations about the increasing threat of Medusa ransomware. 

Medusa, a ransomware-as-a-service (RaaS) variant, was first detected in 2021 and has since targeted over 300 victims across multiple critical infrastructure sectors. Industries such as healthcare, law, education, insurance, technology, and manufacturing have been particularly affected, highlighting the wide reach and severity of the ransomware’s impact. Medusa initially operated as a closed ransomware variant, meaning its developers had full control over its deployment and operations. 

Over time, it transitioned to an affiliate-based model, allowing external cybercriminals to use the ransomware while keeping certain aspects, such as ransom negotiations, under the control of the original developers. This shift has allowed Medusa to expand its reach, increasing its effectiveness as a cyber threat. Medusa demands ransoms ranging from $100,000 to as much as $15 million. 

Like many modern ransomware variants, it employs double extortion tactics—stealing sensitive data before encrypting victim networks. This strategy puts additional pressure on victims, as attackers can threaten to leak or sell stolen data if the ransom is not paid. Cybersecurity researchers from Symantec’s Threat Hunter team recently reported a rise in Medusa-related attacks over the past year. 

Medusa’s developers use initial access brokers (IABs) to gain entry into victim networks. These brokers operate within cybercriminal forums and marketplaces, selling access to compromised systems for amounts ranging from $100 to $1 million. Medusa affiliates rely on phishing campaigns and vulnerability exploitation to gain initial access, making it crucial for organizations to bolster their email security and patch known vulnerabilities. Once inside a system, Medusa operators use “living-off-the-land” (LotL) techniques, leveraging legitimate system tools to evade detection while conducting reconnaissance, data theft, and lateral movement.

Given Medusa’s evolving tactics, cybersecurity experts stress the importance of proactive defense measures. Organizations should deploy security patches, implement network segmentation, and restrict access to critical services from untrusted sources. Dan Lattimer, area vice president for Semperis in the UK and Ireland, emphasized the need for an “assumed breach” mindset, urging companies to shift from a prevention-focused approach to rapid detection, response, and recovery. 

As ransomware attacks grow more sophisticated, organizations must remain vigilant, continuously updating their cybersecurity strategies to mitigate risks and strengthen their defenses against threats like Medusa.

New Malware Impersonates Browser Extensions to Steal Login Credentials

 

Cybercriminals are continually evolving their tactics to evade antivirus detection and trick users into installing malicious software. One of the latest threats involves malware that impersonates legitimate browser extensions, allowing attackers to steal login credentials while remaining undetected. Although this discovery is concerning, researchers have identified the vulnerability before it could be widely exploited, giving security teams time to respond. 

According to a report by SquareX Labs, this attack starts with scammers developing seemingly useful browser extensions, such as an AI-powered transcription tool. To avoid malware detection, they distribute the extension outside official platforms like the Chrome Web Store or Google Play. Users are then encouraged to pin the extension for easy access, allowing it to quietly monitor their browsing habits over time. 

Once installed, the malicious extension collects data on the user’s existing extensions, particularly those used for handling sensitive information, such as password managers. When the right opportunity arises, it disables the legitimate extension and replaces its icon with an identical version. If the user attempts to access their password manager, they unknowingly interact with the fake extension instead. 

To further deceive users, the fraudulent extension displays a message stating that their session has expired, requiring them to log in again. However, rather than accessing their accounts, victims unknowingly submit their credentials directly to cybercriminals. With this information, attackers can break into password vaults, gaining access to sensitive data, stored passwords, and linked accounts. This method is particularly dangerous because it exploits trust in well-known extensions. 

Unlike traditional phishing attempts, which rely on fake websites or deceptive emails, this attack leverages the user’s own browser environment, making it harder to detect. Victims may not realize they’ve been compromised until they notice unauthorized activity on their accounts. Despite the sophistication of this attack, there is no immediate reason for panic. Security researchers identified the exploit before cybercriminals could widely deploy it, and browser developers have been alerted to the risk. 

However, this incident underscores the importance of practicing good cybersecurity habits. Users should only install browser extensions from trusted sources like the Chrome Web Store, avoid third-party downloads, and check reviews before installation. 

Additionally, enabling multi-factor authentication (MFA) on important accounts can provide an extra layer of security, reducing the risk of credential theft. As cyber threats continue to evolve, staying informed and cautious about software installations remains crucial to maintaining online security.

Strengthening PC Security with Windows Whitelisting

 

Windows Defender, the built-in antivirus tool in Windows, provides real-time protection against malware by scanning for suspicious activity and blocking known threats using an extensive virus definition database. However, no antivirus software can completely prevent users from unknowingly installing harmful programs. 

Just like the famous Trojan horse deception, malicious software often enters systems disguised as legitimate applications. To counter this risk, Windows offers a security feature called whitelisting, which restricts access to only approved programs. Whitelisting allows administrators to create a list of trusted applications. Any new program attempting to run is automatically blocked unless explicitly authorized. 

This feature is especially useful in environments where multiple users access the same device, such as workplaces, schools, or shared family computers. By implementing a whitelist, users cannot accidentally install or run malware-infected software, significantly reducing security risks. Additionally, whitelisting provides an extra layer of protection against emerging threats that may not yet be recognized by antivirus databases. 

To configure a whitelist in Windows, users can utilize the Local Security Policy tool, available in Windows 10 and 11 Pro and Enterprise editions. While this tool is not included by default in Windows Home versions, it can be manually integrated. Local Security Policy enables users to manage Applocker, a built-in Windows feature designed to enforce application control. 

Applocker functions by setting up rules, similar to how a firewall manages network access. Applocker supports both whitelisting and blacklisting. A blacklist allows all applications to run except those explicitly blocked. However, since thousands of new malware variants emerge daily, it is far more effective to configure a whitelist—permitting only pre-approved applications and blocking everything else. This approach ensures that unknown or unauthorized programs do not compromise system security. 

Microsoft previously provided Software Restriction Policies (SRP) to enforce similar controls, but this feature was disabled starting with Windows 11 22H2. For users seeking a simpler security solution, Windows also provides an option to limit installations to only Microsoft Store apps. This setting, found under Apps > Advanced settings for apps, ensures that users can only download and install verified applications. 

However, advanced users can bypass this restriction using winget, a command-line tool pre-installed in newer Windows versions that allows software installation outside the Microsoft Store. Implementing whitelisting is a proactive security measure that helps safeguard PCs against unauthorized software installations. 

While Windows Defender effectively protects against known threats, adding a whitelist further reduces the risk of malware infections, accidental downloads, and security breaches caused by human error. By taking control of which programs can run on a system, users can enhance security and prevent potential cyber threats from gaining access.

LegionLoader Malware Resurfaces with Evasive Infection Tactics

 

Researchers at TEHTRIS Threat Intelligence have uncovered a new wave of LegionLoader, a malware downloader also known as Satacom, CurlyGate, and RobotDropper. This sophisticated threat has been rapidly gaining momentum, with over 2,000 samples identified in recent weeks. 

According to TEHTRIS, the ongoing campaign began on December 19, 2024, and has since spread globally, with Brazil emerging as the most affected country, accounting for around 10% of reported cases. LegionLoader primarily infects systems through drive-by downloads, where users unknowingly download malicious software from compromised websites. 

Cybercriminals behind this campaign frequently leverage illegal download platforms and unsecured web pages, which are quickly taken down after redirecting victims to Mega cloud storage links containing a single ZIP file. These ZIP archives house a 7-Zip password-protected file, making it difficult for security tools to scan the contents. 

To further deceive users, a separate image file displays the password required for extraction, enticing them to execute the malware. Once extracted, LegionLoader is deployed as an MSI (Microsoft Installer) file, requiring user interaction to execute. TEHTRIS researchers found that antivirus detection rates for these MSI files range between 3 and 9 out of 60, indicating the malware’s ability to evade traditional security measures. 

The MSI file also includes two key anti-sandbox mechanisms: a fake CAPTCHA prompt to prevent automated analysis and a virtual environment detection feature using Advanced Installer. These obstacles make it challenging for security researchers to analyze the malware in controlled environments. Upon execution, LegionLoader extracts multiple files into the system’s %APPDATA% directory, including clean DLLs, executables, and a password-protected archive containing the primary payload. 

The malware then uses UnRar.exe to extract a DLL file, which is sideloaded using obsffmpegmux.exe to execute the next stage of the attack. Notably, the obs.dll payload is crafted to evade detection by security tools. TEHTRIS analysis found that most of its exports are empty, while the few containing code appear intentionally misleading, likely to slow down forensic investigation. 

Further examination using BinDiff revealed that while different obs.dll samples were structurally identical, variations existed in their second-stage payloads. During dynamic analysis, researchers observed shellcode decryption, leading to the execution of another malicious component. This secondary stage communicates with hardcoded command-and-control (C2) servers, though all identified C2 domains were inactive at the time of analysis, preventing further insights into the malware’s final objective. 

If all infection stages are completed, LegionLoader attempts to execute a final payload using rundll32.exe. The malware downloads an additional file, places it in a randomly named directory under %TMP%, and launches it as svchost.exe. Given the use of rundll32.exe, researchers suspect the final payload is another malicious DLL, though its specific function remains unknown.

To protect against LegionLoader, security experts advise avoiding software downloads from unverified sources and implementing behavior-based detection strategies. These proactive measures can help mitigate the risks posed by evolving malware threats.

2024’s Most Dangerous Malware: A Wake-Up Call for Cybersecurity

 

OpenText, a leader in cybersecurity insights, has released its eagerly awaited “Nastiest Malware of 2024” list, highlighting some of the most destructive and adaptive cyber threats of the year. The list illustrates how ransomware and other malicious software continue to evolve, particularly regarding their impact on critical infrastructure. As cybercriminals refine their tactics, the need to strengthen cybersecurity measures has become increasingly urgent. Organizations around the globe are projected to boost their cybersecurity spending by 14.3% in 2024, raising total investments to over $215 billion, which reflects the magnitude of the challenges posed by these threats. 

LockBit claimed the title of the most dangerous malware of the year. This ransomware-as-a-service (RaaS) entity has demonstrated its ability to evade law enforcement efforts, including those from the FBI. Its ongoing attacks on critical infrastructure showcase its resilience and technical prowess. According to the FBI, LockBit was responsible for 175 reported attacks on essential systems in 2023 alone. The group’s bold ambition to target one million businesses emphasizes its threat level and solidifies its position in the ransomware landscape. 

Akira, a relatively new player, has rapidly gained infamy for its aggressive tactics. This ransomware has been particularly active in industries such as healthcare, manufacturing, and finance, using advanced encryption methods to cause significant disruption. Its retro-inspired branding contrasts sharply with its destructive potential, making it a popular choice among cybercriminal affiliates. 

Meanwhile, RansomHub, which may have connections to the infamous Black Cat (ALPHV) group, has made headlines with its high-profile attacks, including a daring strike on Planned Parenthood that compromised sensitive patient data. 

Other significant threats include Dark Angels, recognized for its precision-targeted attacks on Fortune 50 companies, and Play Ransomware, which takes advantage of vulnerabilities in FortiOS systems and RDP servers. Redline Stealer, while not technically ransomware, this type of threat significantly endangers organizations by focusing on stealing credentials and sensitive information. Each of these threats illustrates how cybercriminals are continually pushing the limits, employing advanced tactics to stay ahead of defenses. 

Muhi Majzoub, OpenText’s EVP and Chief Product Officer, notes that the increase in ransomware targeting critical infrastructure highlights the growing risks to national security and public safety. At the same time, the heightened emphasis on cybersecurity investments is a positive indication that organizations are recognizing these threats. However, the ability of ransomware groups to adapt remains a significant worry, as these criminals continue to leverage new technologies, including artificial intelligence, to create more sophisticated attacks. 

The findings from this year reveal a harsh truth: while progress in cybersecurity is being made, the rapid pace of innovation in malware development poses an ongoing challenge. As companies enhance their vigilance and dedicate more resources to protect vital systems, the battle against cyber threats is far from finished. The changing nature of these attacks requires ongoing adaptation, collaboration, and investment to protect the essential services that support modern society.

Comprehensive Hacker Toolkit Uncovered: A Deep Dive into Advanced Cyberattack Tools

 

Cybersecurity researchers have recently uncovered a vast and sophisticated hacker toolkit that provides a comprehensive suite of tools for executing and maintaining cyberattacks. Found in an open directory in December 2023, the discovery offers a rare glimpse into the methodologies and tools employed by modern cybercriminals. The toolkit includes a range of batch scripts and malware targeting both Windows and Linux systems, showcasing the attackers’ ability to compromise systems, maintain long-term control, and exfiltrate data.  

Among the most significant tools identified were PoshC2 and Sliver, two well-known command and control (C2) frameworks. Although these open-source tools are typically used by penetration testers and red teams to simulate attacks and test security, they have been repurposed by threat actors for malicious purposes. The presence of these frameworks within the toolkit indicates the attackers’ intent to establish persistent remote access to compromised systems, allowing them to conduct further operations undetected. In addition to these frameworks, the toolkit contained several custom batch scripts designed to evade detection and manipulate system settings. 

Scripts such as atera_del.bat and atera_del2.bat were specifically crafted to remove Atera remote management agents, thereby eliminating traces of legitimate administrative tools. Other scripts, like backup.bat and delbackup.bat, were aimed at deleting system backups and shadow copies, a common tactic employed in ransomware attacks to prevent data recovery. Researchers from DFIR Report also noted the presence of clearlog.bat, a script capable of erasing Windows event logs and removing evidence of Remote Desktop Protocol (RDP) usage. This highlights the attackers’ emphasis on covering their tracks and minimizing the chances of detection. 

Additionally, the toolkit included more specialized tools such as cmd.cmd, which disables User Account Control and modifies registry settings, and def1.bat and defendermalwar.bat, which disable Windows Defender and uninstall Malwarebytes. The discovery of this hacker toolkit underscores the growing sophistication of cyberattacks and the need for organizations to adopt robust cybersecurity measures. With tools designed to disable critical services, delete backups, and evade antivirus software, the toolkit serves as a stark reminder of the evolving threat landscape. 

Cybersecurity experts advise organizations to implement comprehensive security strategies, including regular system updates, employee training, and advanced threat detection systems, to protect against such sophisticated attack toolkits. The presence of tools like Sliver and PoshC2 within the toolkit suggests that these servers were likely used in ransomware intrusion activities. Many of the scripts found attempted to stop services, delete backups and shadow copies, and disable or remove antivirus software, further supporting this theory. 

As cyber threats continue to evolve, the discovery of this toolkit provides valuable insights into the methods and tools employed by modern cybercriminals. Organizations must remain vigilant and proactive in their cybersecurity efforts to protect against the increasingly sophisticated tactics used by threat actors.

Customer Data Exposed Cyberattacks Cybersecurity Data Breach Malwares MyGov App NSW Bug

Data of 3700 Customers Exposed by the Service NSW Bug

 


It has been confirmed that Greg Wells, Service NSW's chief executive, said that the personal information of 3,700 customers was left exposed. This incident occurred on March 20 between 1:20 pm and 2:54 pm. 

Earlier this week, 3700 affected customers received an email from Service NSW's chief executive Greg Wells. The email informed them that their information may have been exposed for 90 minutes due to an update on the company's website on March 20. 

The agency says logged-in individuals could now access the personal information of other logged-in customers who also use Service NSW services due to a privacy incident. The exposed information could include details such as the customer's driving license number, vehicle registration number, mobile number, and your child's name. 

As stated in the email to those affected, Service NSW believes the risk of being harmed by this incident is very low. In addition, this incident was not a cyberattack. Based on Service NSW information, the incident was meant to affect only the website and did not impact the mobile app. 

There were only a few customers affected by this problem who logged on to the website during that period. There was a possibility that they could access other users' data simultaneously. As far as app users are concerned, it does not apply to them. There was no breach of personal data involved in the matter, according to a representative of the government agency in NSW. The issue affected only the landing dashboard page. After 90 minutes, the dashboard page on the landing page was taken down, and the issue was resolved quickly. 

In the email, the customer was advised to be aware of suspicious communications. They should keep an eye out for them as soon as they receive them. Affected customers are informed by email that they do not have to act immediately. This is because their details were “only accessible for a short period to another logged-in individual and were not searchable” because they were not available to anyone else at any time. 

Service NSW has begun an investigation into the incident to prevent similar issues in the future. In addition, the agency has suggested that customers contact ID Support NSW to find out what they can do to better their chances of regaining their identity and for counseling. 

There was an incident that occurred just a few days after federal officials announced they were planning to add a digital Medicare card to the Service NSW app. This was as a means of improving accessibility.

The digital card can be used by MyGov app users from Thursday (31 March) and there has been no interruption in service. In their view, the government believes the digital version will provide more security and be more accessible to the public, both of which will increase efficiency.

iCloud Keychain Data and Passwords are at Risk From MacStealer Malware

 


Uptycs, a cybersecurity company that discovered the information-stealing malware while searching for threats on the dark web, is warning that Mac computers have been the latest targets of updated info-stealing malware. 

The iCloud Keychain can easily access cryptocurrency wallets with the help of MacStealer. This is an innovative malware that steals your credentials from your web browsers, cryptocurrency wallets, and potentially sensitive files stored in your iCloud Keychain. 

The MacStealer malware is distributed as malware-as-a-service (MaaS), whereby the developer sells pre-built builds for $100, allowing customers to run their marketing campaigns and spread the malware to their victims. 

On the dark web, cybercriminals use Mac computers as a breeding ground to launch malware and conduct illegal activities. This makes the dark web a prime place to conduct illegal activities and launch malware. 

Upon discovering the newly discovered macOS malware, the Uptycs threat research team reported that it could run on multiple versions of Mac OS. This included the current Mac OS, Catalina (10.15), and the latest and greatest Apple OS, Ventura (13.2). 

Sellers claim that the malware is still in beta testing and that there are no panels or builders available. In China, Big Sur, Monterey, and Ventura provides rebuilt DMG payloads that infect macOS with malware. 

To charge a low $100 price for a piece of malware without a builder and panel, the threat actor uses this fact. Despite this, he will release more advanced features as soon as possible. 

A new threat named MacStealer is using Telegram as a command and control (C2) platform to exfiltrate data, with the latest example being called PharmBot. There is a problem that affects primarily computers running MacOS Catalina and later with CPUs built on the M1 or M2 architecture. 

According to Uptycs' Shilpesh Trivedi and Pratik Jeware in their latest report on the MacStealer exploit, the tool steals files and cookies from the victim's browser and login information. 

In its first advertising on online hacking forums at the beginning of the month, this project was advertised for $100, but it is still far from being finished. There is an idea among the malware authors of adding features to allow them to access notes in Apple's Notes app and Safari web browser. 

Functioning of Malware

MacStealer is distributed by the threat actors using an unsigned DMG file which is disguised as being something that can be executed on Mac OS if it is tricked into going into the system.

As a result, the victim is presented with a fake password prompt to run the command, which is made to look real. The compromised machine becomes vulnerable to malware that collects passwords from it. 

Once it has collected all the data described in the previous section, the malware then begins to spread. As soon as the stolen data is collected, it is stored in a ZIP file. It is then sent to a remote server for processing and analysis. Later on, the threat actor will be in a position to collect this information as well.

Additionally, MacStealer is also able to send some basic information to a pre-configured Telegram channel, which allows the operator to be notified immediately when updates to the stolen data have been made, which will enable him to download the ZIP file immediately as well.

What can You do to Protect Your Mac?

You can do a few things right now to ensure that you have the latest software update installed on your Mac computer, beginning with opening the Settings app and checking that it is the latest version. 

The first thing you should do is install it as soon as possible if it has not been installed already. You should make sure that all of your Apple devices are up-to-date before you begin using them since Apple is constantly improving its security. 

Your devices will be protected from malware if you use antivirus software, which protects you from potentially malicious links on the internet. By clicking the magnifying glass icon at the top of my webpage, you can find my expert review of the highest-rated antivirus protection for your Windows, Mac, Android, and iOS devices, which includes reviews of which ranked antivirus protection for Windows, Mac, Android, and iOS devices.  

Different forms of malware, such as email attachments, bogus software downloads, and other techniques of social engineering, are utilized to spread stealer malware. 

Keeping up-to-date the operating system and security software of the computer is one of the best ways to mitigate such threats. In addition, they should not download files from unknown sources or click on links they find on the internet. 

"It becomes more important for data stored on Macs to be protected from attackers as Macs become more popular among leadership teams as well as development and design teams within organizations", SentinelOne researcher Phil Stokes said in a statement last week.
