Cybercriminals Behind DOGE Big Balls Ransomware Demand $1 Trillion, Troll Elon Musk

 

A cybercrime group notorious for its outrageous tactics has resurfaced with a ransomware attack demanding an unbelievable $1 trillion from its victims. The group, responsible for the DOGE Big Balls ransomware campaign, has updated its ransom demands with bizarre references to Elon Musk and the Dogecoin meme culture, blending humor with a highly dangerous threat.  

According to a report by Trend Micro researchers Nathaniel Morales and Sarah Pearl Camiling, the attackers are leveraging a modified form of the FOG ransomware to carry out these intrusions. The malware exploits a long-known Windows vulnerability (CVE-2015-2291) through a multi-step PowerShell script that allows deep access into infected systems. Delivered via deceptive shortcut files inside ZIP folders, the malware initiates a chain reaction to execute its payload. Though the ransom note may appear comical—mocking Musk’s past corporate directives and making false claims about stealing “trilatitude and trilongitude” coordinates—the security community warns against taking this threat lightly. 

The ransomware performs environment checks to avoid detection, analyzing machine specs, RAM, and registry entries to detect if it’s being run in a sandbox. If any signs of monitoring are detected, the malware will exit silently. The FBI, in its April 2025 Internet Crime Report, highlighted ransomware—particularly FOG variants—as a dominant threat, impacting critical infrastructure and organizations across the U.S. The report revealed over 100 known FOG ransomware infections between January and March 2025, making it the most reported strain of the year thus far. Beyond encryption, the malware also exfiltrates sensitive data and pressures victims to communicate via the Tor network for instructions. 

The attackers claim stolen files and urge victims not to involve law enforcement, adding a “don’t snitch now” line in their taunting ransom message. Despite its absurd tone, security leaders emphasize the seriousness of the attack. Dr. Ilia Kolochenko, CEO of ImmuniWeb, cautions that many victims discreetly pay ransoms to groups known for not leaking data—urging companies to seek legal and cybersecurity advice before making decisions. 

Although the group hides behind memes and internet jokes, their ability to cause significant operational and financial disruption is very real. Their humor might distract, but the threat demands urgent attention.

Blockchain cryptocurrency Cyber Attacks Cybersecurity GitHub Hacker JavaScript Linkedin malware python

North Korean Hacker Group Targets Cryptocurrency Developers via LinkedIn

 

A North Korean threat group known as Slow Pisces has launched a sophisticated cyberattack campaign, focusing on developers in the cryptocurrency industry through LinkedIn. Also referred to as TraderTraitor or Jade Sleet, the group impersonates recruiters offering legitimate job opportunities and coding challenges to deceive their targets. In reality, they deliver malicious Python and JavaScript code designed to compromise victims' systems.

This ongoing operation has led to massive cryptocurrency thefts. In 2023 alone, Slow Pisces was tied to cyber heists exceeding $1 billion. Notable incidents include a $1.5 billion breach at a Dubai exchange and a $308 million theft from a Japanese firm. The attackers typically initiate contact by sending PDFs containing job descriptions and later provide coding tasks hosted on GitHub. Although these repositories mimic authentic open-source projects, they are secretly altered to carry hidden malware.

As victims work on these assignments, they unknowingly execute malicious programs like RN Loader and RN Stealer on their devices. These infected projects resemble legitimate developer tools—for instance, Python repositories that claim to analyze stock market data but are actually designed to communicate with attacker-controlled servers.

The malware cleverly evades detection by using YAML deserialization techniques instead of commonly flagged functions like eval or exec. Once triggered, the loader fetches and runs additional malicious payloads directly in memory, making the infection harder to detect and eliminate.

One key malware component, RN Stealer, is built to extract sensitive information, including credentials, cloud configuration files, and SSH keys, especially from macOS systems. JavaScript-based versions of the malware behave similarly, leveraging the Embedded JavaScript templating engine to conceal harmful code. This code activates selectively based on IP addresses or browser signatures, targeting specific victims.

Forensic investigations revealed that the malware stores its code in hidden folders and uses HTTPS channels secured with custom tokens to communicate. However, experts were unable to fully recover the malicious JavaScript payload.

Both GitHub and LinkedIn have taken action against the threat.

"GitHub and LinkedIn removed these malicious accounts for violating our respective terms of service. Across our products, we use automated technology, combined with teams of investigation experts and member reporting, to combat bad actors and enforce terms of service. We continue to evolve and improve our processes and encourage our customers and members to report any suspicious activity," the companies said in a joint statement.

Given the increasing sophistication of these attacks, developers are urged to exercise caution when approached with remote job offers or coding tests. It is recommended to use robust antivirus solutions and execute unknown code within secure, sandboxed environments, particularly when working in the high-risk cryptocurrency sector.

Security experts advise using trusted integrated development environments (IDEs) equipped with built-in security features. Maintaining a vigilant and secure working setup can significantly lower the chances of falling victim to these state-sponsored cyberattacks.

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.

'Fog' Attackers Mock Victims With DOGE Ransom Notes

 

Fog ransomware assaults over the last month have included a new ransom note mentioning the US Department of Government Efficiency (DOGE) and enticing victims to propagate the malware to other PCs, Trend Micro said earlier this week. 

Analysis of the latest samples of Fog ransomware, which were published to VirusTotal between March 27 and April 2, 2025, found that they propagated via the transfer of a ZIP file containing an LNK file disguised as a PDF called "Pay Adjustment." This shows that attacks were carried out via phishing emails to employees.

Once the "Pay Adjustment" LNK file is clicked, a PowerShell script named stage1.ps1 is executed, which retrieves multiple payloads from a hacker-controlled domain. These include the ransomware loader cwiper.exe, a bring-your-own-vulnerable-driver (BYOVD) privilege escalation tool named Ktool.exe, a QR code image directing to a Monero wallet, a ransom letter called RANSOMNOTE.txt, and more malicious PowerShell scripts. 

Ktool.exe extracts the vulnerable Intel Network Adapter Diagnostic Driver iQVW64.sys to the %TEMP% folder, passing the target process ID (PID) and a hardcoded key as arguments. Lootsubmit.ps1 and Trackerjacker.ps1 are PowerShell scripts that collect and exfiltrate system information such IP addresses, CPU configurations, MAC addresses, and system geolocations. 

Before dropping the Fog ransomware, the ransomware loader checks to ensure it is not in a sandbox environment. It also drops dbgLog.sys, which tracks encryption-related activities, and readme.txt, an additional ransom note. This ransom note is identical to those found in past Fog ransomware assaults. 

Odd political references

While the final ransom note, readme.txt, is identical to prior attacks, the initial ransom note, RANSOMNOTE.txt, refers to DOGE and includes the names of specific individuals involved with the department. 

The note reads, "Give me five bullet points on what you accomplished for work last week," and refers to emails sent to federal employees in February as part of a DOGE campaign. The note further offers to decrypt the user's data for free if they deliver the malicious files to another person or manually execute the malicious PowerShell commands on someone else's PC. 

Earlier this year, the DoNex ransomware group followed a similar tactic, promising payment to targets in exchange for sharing sensitive company data or spreading the malware throughout their organisation. The PowerShell script also contains bizarre political references, such as the statement "The CIA didn't kill Kennedy, you idiot." The script also launched several politically orientated YouTube videos, including an episode of "Last Week Tonight with John Oliver.”

Advanced persistent threat (APT) Advanced Social Engineering Cyber Attacks cyber espionage espionage Fake Website Phishing emails PowerShell

ClickFix Attacks: North Korea, Iran, Russia APT Groups Exploit Social Engineering for Espionage

ClickFix attacks are rapidly becoming a favored tactic among advanced persistent threat (APT) groups from North Korea, Iran, and Russia, particularly in recent cyber-espionage operations. This technique involves malicious websites posing as legitimate software or document-sharing platforms. Targets are enticed through phishing emails or malicious advertising and then confronted with fake error messages claiming a failed document download or access issue. 


To resolve the supposed problem, users are instructed to click a “Fix” button that directs them to run a PowerShell or command-line script. Executing this script allows malware to infiltrate their systems. Microsoft’s Threat Intelligence division highlighted earlier this year that the North Korean group ‘Kimsuky’ utilized a similar approach through a fake “device registration” page. 

A new report from Proofpoint now confirms that Kimsuky, along with Iran’s MuddyWater, Russia’s APT28, and the UNK_RemoteRogue group, deployed ClickFix techniques between late 2024 and early 2025. Kimsuky’s campaign, conducted between January and February 2025, specifically targeted think tanks involved in North Korean policy research. The attackers initially contacted victims using spoofed emails designed to appear as if they were sent by Japanese diplomats. After gaining trust, they provided malicious PDF attachments leading to a counterfeit secure drive. Victims were then asked to manually run a PowerShell command, which triggered the download of a second script that established persistence with scheduled tasks and installed QuasarRAT, all while distracting the victim with a harmless-looking PDF. 

In mid-November 2024, Iran’s MuddyWater launched its campaign, targeting 39 organizations across the Middle East. Victims received phishing emails disguised as urgent Microsoft security alerts, prompting them to run PowerShell scripts with administrative rights. This led to the deployment of ‘Level,’ a remote monitoring and management (RMM) tool used to conduct espionage activities. Meanwhile, Russian group UNK_RemoteRogue focused on two organizations tied to a leading arms manufacturer in December 2024. Attackers used compromised Zimbra servers to send fake Microsoft Office messages. Clicking the embedded links directed victims to fraudulent Microsoft Word pages featuring Russian-language instructions and a video tutorial. 

Victims executing the provided script unknowingly triggered JavaScript that ran PowerShell commands, connecting their systems to a server managed through the Empire C2 framework. Proofpoint also found that APT28, an infamous Russian cyber-espionage unit, used ClickFix tactics as early as October 2024. In that instance, phishing emails mimicked Google Spreadsheet notifications, including a fake reCAPTCHA and a prompt to execute PowerShell commands. Running these commands enabled attackers to create an SSH tunnel and activate Metasploit, providing them with covert access to compromised machines. 

The growing use of ClickFix attacks by multiple state-sponsored groups underscores the method’s effectiveness, primarily due to the widespread lack of caution when executing unfamiliar commands. To avoid falling victim, users should be extremely wary of running scripts or commands they do not recognize, particularly when asked to use elevated privileges.

Interlock Ransomware Gang Deploys ClickFix Attacks to Breach Corporate Networks

 

Cybersecurity researchers have revealed that the Interlock ransomware gang has adopted a deceptive social engineering technique called ClickFix to infiltrate corporate networks. This method involves tricking users into executing malicious PowerShell commands under the guise of resolving system errors or completing identity verification steps, leading to the deployment of file-encrypting malware. 

While ClickFix attacks have previously been associated with ransomware campaigns, this marks the first confirmed use by Interlock, a ransomware operation that surfaced in late September 2024. The group targets both Windows systems and FreeBSD servers and maintains a dark web leak portal to pressure victims into paying ransoms that can reach millions of dollars. Interlock does not seem to operate as a ransomware-as-a-service (RaaS) model. 

According to Sekoia researchers, Interlock began using ClickFix tactics in January 2025. Attackers set up fake websites mimicking legitimate IT tools—such as Microsoft Teams and Advanced IP Scanner—to lure victims. These fake sites prompt users to click a “Fix it” button, which silently copies a malicious PowerShell script to the user’s clipboard. If run, the command downloads a 36MB PyInstaller payload that installs malware under the guise of a legitimate tool. 

Researchers found the malicious campaign hosted on spoofed domains like microsoft-msteams[.]com, microstteams[.]com, ecologilives[.]com, and advanceipscaner[.]com. Only the last domain led to the actual malware dropper disguised as Advanced IP Scanner. When users unknowingly run the script, a hidden PowerShell window executes actions such as system reconnaissance, persistence via Windows Registry, and data exfiltration. The attackers deploy a range of malware via command-and-control (C2) servers, including LummaStealer, BerserkStealer, keyloggers, and the Interlock RAT—a basic remote access trojan capable of dynamic configuration, file exfiltration, shell command execution, and DLL injection. 

Post-compromise, Interlock operators use stolen credentials to move laterally through networks via RDP, leveraging remote access tools like PuTTY, AnyDesk, and LogMeIn. Data is exfiltrated to Azure Blob Storage, after which the Windows variant of Interlock ransomware is scheduled to run daily at 8:00 PM—a redundancy tactic to ensure encryption if the initial payload fails. The gang’s ransom notes have also evolved, now placing emphasis on the legal and regulatory consequences of leaked data. 

ClickFix attacks are gaining popularity among various cybercriminal groups, with recent reports also linking them to North Korean state-sponsored actors like the Lazarus Group, who use similar tactics to target job seekers in the cryptocurrency sector.

Backdoor Cyber Attacks FortiGate devices Security Patch Symbolic

Over 16,000 Fortinet Devices Infected With the Symlink Backdoor

 

Over 16,000 internet-connected Fortinet devices have been identified as having a new symlink backdoor that permits read-only access to sensitive data on previously compromised systems. 

The Shadowserver Foundation, a threat monitoring platform, has stated that 14,000 machines were exposed. Earlier this week, Shadowserver's Piotr Kijewski told a local media source that the cybersecurity firm now recognises 16,620 devices affected by the newly discovered persistence method. 

Last week, Fortinet notified customers that they had found a new persistence mechanism employed by a threat actor to maintain read-only remote access to files in the root filesystem of previously hacked but now patched FortiGate devices. 

Fortinet stated that this was not due to the exploitation of new vulnerabilities, but rather to attacks beginning in 2023 and continuing into 2024, in which a threat actor used zero days to compromise FortiOS devices. 

After gaining access to the devices, they made symbolic connections to the root file system on SSL-VPN-enabled devices in the language files folder. Even after the initial vulnerabilities were fixed, the threat actor could still access the root file system by browsing to the language files, which are publically available on FortiGate devices with SSL-VPN enabled. 

"A threat actor used a known vulnerability to implement read-only access to vulnerable FortiGate devices. This was achieved via creating a symbolic link connecting the user filesystem and the root filesystem in a folder used to serve language files for the SSL-VPN. This modification took place in the user filesystem and avoided detection," Fortinet stated. 

"Therefore, even if the customer device was updated with FortiOS versions that addressed the original vulnerabilities, this symbolic link may have been left behind, allowing the threat actor to maintain read-only access to files on the device's file system, which may include configurations.” 

Earlier this month, Fortinet began discreetly notifying customers via email about FortiGate devices that FortiGuard discovered as being infected with this symlink backdoor. In order to identify and eliminate this malicious symbolic link from compromised devices, Fortinet has released an improved AV/IPS signature.

Additionally, the firmware has been updated to the most recent version in order to detect and remove the link. The upgrade also stops the integrated web server from serving unrecognised files and folders. Finally, if a device was identified as hacked, it is probable that the threat actors had access to the latest configuration files, including credentials.

Symantec Links Betruger Backdoor Malware to RansomHub Ransomware Attacks

 

A sophisticated custom backdoor malware called Betruger has been discovered in recent ransomware campaigns, with Symantec researchers linking its use to affiliates of the RansomHub ransomware-as-a-service (RaaS) group. The new malware is considered a rare and powerful tool designed to streamline ransomware deployment by minimizing the use of multiple hacking tools during attacks. 

Identified by Symantec’s Threat Hunter Team, Betruger is described as a “multi-function backdoor” built specifically to aid ransomware operations. Its functions go far beyond traditional malware. It is capable of keylogging, network scanning, privilege escalation, credential theft, taking screenshots, and uploading data to a command-and-control (C2) server—all typical actions carried out before a ransomware payload is executed. Symantec notes that while ransomware actors often rely on open-source or legitimate software like Mimikatz or Cobalt Strike to navigate compromised systems, Betruger marks a departure from this norm. 

The tool’s development suggests an effort to reduce detection risks by limiting the number of separate malicious components introduced during an attack. “The use of custom malware other than encrypting payloads is relatively unusual in ransomware attacks,” Symantec stated. “Betruger may have been developed to reduce the number of tools dropped on a network during the pre-encryption phase.” Threat actors are disguising the malware under file names like ‘mailer.exe’ and ‘turbomailer.exe’ to pose as legitimate mailing applications and evade suspicion. While custom malware isn’t new in ransomware operations, most existing tools focus on data exfiltration. 

Notable examples include BlackMatter’s Exmatter and BlackByte’s Exbyte, both created to steal data and upload it to cloud platforms like Mega.co.nz. However, Betruger represents a more all-in-one solution tailored for streamlined attack execution. The RansomHub RaaS operation, previously known as Cyclops and Knight, surfaced in early 2024 and has quickly become a major threat actor in the cybercrime world. Unlike traditional ransomware gangs, RansomHub has focused more on data theft and extortion rather than just data encryption. Since its emergence, RansomHub has claimed several high-profile victims including Halliburton, Christie’s auction house, Frontier Communications, Rite Aid, Kawasaki’s EU division, Planned Parenthood, and Bologna Football Club. 

The group also leaked Change Healthcare’s stolen data after the BlackCat/ALPHV ransomware group’s infamous $22 million exit scam. More recently, the gang claimed responsibility for breaching BayMark Health Services, North America’s largest addiction treatment provider. BayMark serves over 75,000 patients daily across more than 400 locations in the US and Canada. According to the FBI, as of August 2024, RansomHub affiliates have compromised over 200 organizations, many of which are part of critical infrastructure sectors such as government, healthcare, and energy. 

As ransomware groups evolve and adopt more custom-built malware like Betruger, cybersecurity experts warn that defenses must adapt to meet increasingly sophisticated threats.

Cyberattacks Hit U.S. Healthcare Firms, Exposing Data of Over 236,000 People

 


Two separate data breaches in the U.S. have exposed sensitive information of more than 236,000 people. These incidents involve two organizations: Endue Software in New York and Medical Express Ambulance (MedEx) in Illinois.

Endue Software creates software used by infusion centers, which help treat patients with medication delivered directly into their bloodstream. In February this year, the company found that hackers had broken into its system. This breach led to the exposure of personal details of around 118,000 individuals. The leaked information included full names, birth dates, Social Security numbers, and unique medical record identifiers. While there is currently no proof that the stolen data has been used illegally, the company isn’t taking any chances. It has added more safety tools and measures to its systems. It is also offering one year of free credit monitoring and identity protection to help affected people stay safe from fraud.

In a different case, MedEx, a private ambulance service provider based in Illinois, reported that it was also hit by a cyberattack. This breach happened last year, but the details have recently come to light. Information belonging to more than 118,000 people was accessed by attackers. The data included health records, insurance information, and even passport numbers in some cases.

These events are part of a larger pattern of cyberattacks targeting the healthcare industry in the U.S. In recent months, major organizations like UnitedHealth Group and Ascension Health have also suffered large-scale data breaches. Cybercriminals often go after hospitals and medical companies because the data they store is very valuable and can be used for scams or identity theft.

Both Endue and MedEx are working with cybersecurity experts to investigate the breaches and improve their systems. People affected by these incidents are being advised to be extra cautious. They should use the free protection services, monitor their bank and credit accounts, and immediately report anything unusual.

Top U.S. Banks Cut Off Digital Data Sharing With OCC After Major Cyberattack

 

Several of the largest banks in the United States have curtailed or reassessed how they share sensitive data with the Office of the Comptroller of the Currency (OCC), after a significant cyberattack compromised the regulator’s email system. 

According to Bloomberg, JPMorgan Chase and Bank of New York Mellon have paused all electronic communications with the OCC. Bank of America is continuing to share data, but through what it considers more secure digital channels. The decision follows the discovery that hackers had accessed over 100 email accounts at the OCC for more than a year—a breach labeled a “major incident” by both the OCC and the U.S. Treasury Department. 

The hackers reportedly obtained highly sensitive information related to financial institutions, although their identities remain unknown. The OCC, a bureau under the Treasury, oversees over 1,000 national banks and savings associations, including the U.S. branches of foreign institutions. Among the materials potentially exposed are reports on cybersecurity protocols, internal vulnerability assessments, and National Security Letters—documents that may contain classified intelligence regarding terrorism or espionage. 

Banks have raised concerns about the extent of the breach and the OCC’s communication about the incident. Some financial institutions reportedly did not learn of the scope of the compromise until media coverage surfaced. As a result, there is growing distrust among regulated institutions regarding how the OCC has handled disclosure and mitigation. The OCC said it is actively working with independent cybersecurity experts, including Mandiant and Microsoft, to investigate the breach and determine whether stolen data has surfaced on the dark web. 

A contractor is also reviewing two internal communication systems—BankNet and another used for transferring large files—to assess whether they were affected. While JPMorgan and BNY Mellon have suspended digital transmissions, Citigroup has continued data sharing due to its existing consent order with the OCC. It remains unclear whether other major banks like Wells Fargo or Goldman Sachs have taken similar steps. Experts warn that the breach could enable targeted cyberattacks or extortion attempts, as the stolen material may offer insight into institutional vulnerabilities. 

According to former Treasury CIO Eric Olson, the exposed data is “as sensitive as it gets.” The incident has drawn attention from Congress, with both the House Financial Services Committee and the Senate Banking Committee seeking more information. Experts view the banks’ decision to reduce data sharing as a sign of eroding trust in the OCC’s ability to safeguard critical regulatory communications.

Fourlis Group Confirms €20 Million Loss from IKEA Ransomware Attack

 

Fourlis Group, the retail operator responsible for IKEA stores across Greece, Cyprus, Romania, and Bulgaria, has revealed that a ransomware attack targeting its systems in late November 2024 led to significant financial losses. The cyber incident, which coincided with the busy Black Friday shopping period, disrupted critical parts of the business and caused damages estimated at €20 million (around $22.8 million). 

The breach initially surfaced as unexplained technical problems affecting IKEA’s e-commerce platforms. Days later, on December 3, the company confirmed that the disruptions were due to an external cyberattack. The attack affected digital infrastructure used for inventory restocking, online transactions, and broader retail operations, mainly impacting IKEA’s business. Other brands under the Fourlis umbrella, including Intersport and Holland & Barrett, were largely unaffected.  

According to CEO Dimitris Valachis, the company experienced a loss of approximately €15 million in revenue by the end of 2024, with an additional €5 million impact spilling into early 2025. Fourlis decided not to comply with the attackers’ demands and instead focused on system recovery through support from external cybersecurity professionals. The company also reported that it successfully blocked a number of follow-up attacks attempted after the initial breach. 

Despite the scale of the attack, an internal investigation supported by forensic analysts found no evidence that customer data had been stolen or exposed. The incident caused only a brief period of data unavailability, which was resolved swiftly. As part of its compliance obligations, Fourlis reported the breach to data protection authorities in all four affected countries, reassuring stakeholders that personal information remained secure. Interestingly, no known ransomware group has taken responsibility for the attack. This may suggest that the attackers were unable to extract valuable data or are holding out hope for an undisclosed settlement—though Fourlis maintains that no ransom was paid. 

The incident highlights the growing risks faced by digital retail ecosystems, especially during peak sales periods when system uptime is critical. As online platforms become more central to retail operations, businesses like Fourlis must invest heavily in cybersecurity defenses. Their experience reinforces the importance of swift response strategies, external threat mitigation support, and robust data protection practices to safeguard operations and maintain customer trust in the face of evolving cyber threats.

Ransomware Attacks Surge in Q1 2025 as Immutable Backup Emerges as Critical Defense

Ransomware attacks have seen a dramatic rise in the first quarter of 2025, with new research from Object First revealing an 84% increase compared to the same period in 2024. This alarming trend highlights the growing sophistication and frequency of ransomware campaigns, with nearly two-thirds of organizations reporting at least one attack in the past two years. 

The findings suggest that ransomware is no longer a matter of “if” but “when” for most businesses. Despite the increased threat, Object First’s study offers a silver lining. A large majority—81% of IT decision-makers—now recognize that immutable backup storage is the most effective defense against ransomware. Immutable storage ensures that once data is written, it cannot be changed or deleted, offering a critical safety net when other security measures fail. This form of storage plays a key role in enabling organizations to recover their data without yielding to ransom demands. 

However, the report also highlights a concerning gap between awareness and action. While most IT professionals acknowledge the benefits of immutable backups, only 59% of organizations have actually implemented such storage. Additionally, just 58% maintain multiple copies of their data in separate locations, falling short of the recommended 3-2-1 backup strategy. This gap leaves many companies dangerously exposed. The report also shows that ransomware actors are evolving their methods. A staggering 96% of organizations that experienced ransomware attacks in the last two years had their backup systems targeted at least once. Even more concerning, 10% of them had their backup storage compromised in every incident. 

These findings demonstrate how attackers now routinely seek to destroy recovery options, increasing pressure on victims to pay ransoms. Many businesses still place heavy reliance on traditional IT security hardening. In fact, 61% of respondents believe this approach is sufficient. But ransomware attackers are adept at bypassing such defenses using phishing emails, stolen credentials, and remote access tools. That’s why Object First recommends adopting a “breach mentality”—an approach that assumes an eventual breach and focuses on limiting damage. 

A Zero Trust architecture, paired with immutable backup, is essential. Organizations are urged to segment networks, restrict user access to essential data only, and implement multi-factor authentication. As cloud services grow, many companies are also turning to immutable cloud storage for flexible, scalable protection. Together, these steps offer a stronger, more resilient defense against today’s aggressive ransomware landscape.

CVE CVEs Cyber Attacks Malware Attack Malwares Microsoft ransomware attacks Ransomware group Ransomwares

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.

NSA Warns of Fast Flux DNS Evasion Employed by Cybercrime Outfits

 

The FBI, the Cybersecurity and Infrastructure Security Agency, and a group of international partners have warned that cyber threat groups are utilising a technique known as "fast flux" to conceal the whereabouts of malicious servers, which poses a substantial threat to national security. 

Authorities have warned that both criminal and state-linked threat outfits have exploited Domain Name System records that change frequently to obscure the locations of these servers. They can also build extremely resilient command and control (C2) infrastructure to mask their malicious activities, particularly when dealing with botnets. 

Security officials also stated that fast flux techniques are utilised not only for C2 communications, but also in phishing attempts to prevent social engineering websites from being blacklisted or taken down. 

Authorities did not directly identify any threat actors currently employing the approach or indicate whether a campaign utilising fast flux is underway. They did, however, make reference to earlier activities, pointing out that fast flux was utilised in ransomware attacks connected to Hive and Nefilim. The advisory further claims that Gamaredon, a threat actor supported by Russia, has concealed threat activity using rapid flux. 

According to Andy Piazza, senior director of threat intelligence at Unit 42 of Palo Alto Networks, quick flux is a tactic used by attackers to put a financial burden on security operations teams by making it extremely expensive and challenging to identify ongoing threat activities.

Piazza stated that Trident Ursa employed fast flux during the early stages of Russia's invasion of Ukraine. According to Piazza, fast flux enables an opponent to quickly modify their infrastructure by changing hundreds of domains per minute. 

The advisory notes that there are two variations of the method known as single flux and double flux. Multiple IP addresses are linked to a single domain name using single flux. Double Flux modifies the DNS name server in addition to the domain name. 

Prevention tips

Authorities recommended a number of actions to recognise and mitigate the activity: 

  • Configure anomaly detection systems for DNS query logs. 
  • Employ threat intelligence feeds to detect known fast flux domains and associated IP addresses. 
  • Increase the logging and monitoring of DNS traffic. 
  • Consider sinkholing a hostile domain.

DragonForce Asserts Dominance Over RansomHub Ransomware Network

 


A series of targeted attacks involving DragonForce, a ransomware group that has reportedly been operating in the Middle East and North Africa region (MENA) are reported to have been launched against companies in the Kingdom of Saudi Arabia (KSA) amidst the escalating cyber threats throughout the region. A significant incident involving a real estate and construction company based in Riyadh, which underscored the group's commitment to targeting high-value targets within critical sectors, was one of the most significant incidents involving the group. 

In the recent past, there has been an increase in the sophistication of cyberattacks targeting major companies and vital infrastructure around the region, resulting in this recent development. In addition to demonstrating the increasing capabilities of threat actors such as DragonForce, this breach also emphasizes the need to maintain enhanced vigilance and preparedness among cybersecurity professionals and law enforcement agencies within the Kingdom of Saudi Arabia and its surrounding countries. 

Experts are anticipating that as the group's tactics continue to be effective, they will expand beyond MENA in terms of geographic scale. This incident has wider implications than just the immediate victims. As a cautionary marker of the rapidly evolving threat landscape, this incident serves as a warning of the threats that may threaten global digital security systems in the future. 

Cyble, a cybersecurity firm, has confirmed that a threat actor known as DragonForce recently posted a message on the RAMP cybercrime forum announcing a new “project.” This announcement was later mirrored on DragonForce's onion-based data leak site (DLS), marking the beginning of a new operational infrastructure for DragonForce. A part of this initiative was the introduction of two new onion domains that DragonForce launched, both protected by CAPTCHA verification, which aligned with the group's traditional Tor-based deployment practices. 

Interestingly, both of these sites are prominently branded and emblazoned with RansomHub, a group that specializes in ransomware. While it is still unclear whether DragonForce has seized control of RansomHub in the past or has just infiltrated its systems, Cyble has observed that RansomHub's onion site has been unavailable since March 31. As a result of this prolonged downtime, there has been considerable speculation within the cyber security community as to whether DragonForce may be planning to acquire or hostilely take over the RansomHub infrastructure. 

In addition to this development, DragonForce recently formally announced its plans to expand its ransomware-as-a-service operations, which are aligned with DragonForce's broader strategy of expanding the company's ransomware-as-a-service operations. As part of this initiative, the group introduced an affiliate-based model in which third-party actors—or “franchisees”—can operate under DragonForce brand names. 

As part of the new model, affiliates will reportedly be provided with comprehensive backend support, which includes anti-DDoS defences, advanced encryption protocols, and specialized toolkits that allow them to manage infections across a range of environments, including ESXi, NAS, BSD, and Windows. A significant investment is being made into infrastructure to attract and empower partners, thereby enhancing the group's reach and impact as a whole. This is a deliberate attempt by the group to streamline operations and present a more organized and business-like ransomware platform to victims by including features like encryption status monitoring and persistent communication mechanisms. 

Despite the uncertainty that surrounds RansomHub's future, it is currently possible that it will become fully absorbed under the DragonForce brand or continue to operate independently, but current indicators suggest that a possible consolidation within the ransomware ecosystem may result in increased sophistication and coordination among cybercriminals. 

Despite the increased competition in the ransomware-as-a-service (RaaS) market, DragonForce is positioning itself as a prominent player by offering its affiliates one of the most attractive commission structures on the dark web. This aggressive profit-sharing model aims to attract skilled cybercriminals in an attempt to build an affiliate network that is loyal, results-driven and enables partners to keep up to 80% of ransom payments successfully extorted from victims. A key component of DragonForce's communication strategy is TOX, a Tor-based instant messaging platform that serves as the main channel for communicating with both victims and affiliates as well as serving as a secure, secure means of communicating. 

In addition to providing the public key to the group, RAMP, an underground forum used by ransomware operators and access brokers, is also available to anyone interested in further securing these exchanges. This persistent presence on the platform, especially a forum visit traced back to February 24, 2025, indicates a sustained effort by them to maintain visibility and engagement within the key cybercriminal community. In addition to serving as a recruitment hub, the DragonForce affiliate network is also highlighted in advertisements displayed on RAMP as one of the most reliable networks within the dark web. With support for multiple platforms, including Windows, Linux, and ESXi, the ransomware framework is marketed as a robust system that can deliver consistent payouts while offering extensive back-end support. 

As of January 20th, 2025, the most recent affiliate-related announcements have been posted, but the associated PGP encryption key has been generated since September 2024, further demonstrating the organization's systematic approach to security. A prior operational leak involved sensitive affiliate-facing URLs that were used for extortion from victims. DragonForce underwent significant internal reforms after this. Among these reforms was the implementation of a new vetting process that requires prospective affiliates to provide verifiable evidence of victim access, such as data volume metrics and file trees, to justify their eligibility. 

Essentially, this shift was meant to ensure that only committed and capable individuals could be onboarded, which would lead to improved operational security and integrity for the organization. Furthermore, DragonForce offers a variety of premium services to vetted affiliates, including call services, which allow direct pressure to be applied to victims, as well as advanced decryption capabilities that can be used on NTLM and Kerberos hashes. A lot of these services are especially useful when access brokers are trying to navigate post-compromise stages in environments like Active Directory that are complex. 

It is important to remember that DragonForce ransomware is an independent entity and should not be confused with the Malaysian hacktivist group that operates under the same name. This group has been known for defacing websites and launching DDoS attacks, among other things. While the two organizations share a name, they are completely different in their motivations, structures, and methods, and they are not known to be affiliated with each other. 

As ongoing speculation continues regarding the nature of a potential alliance between RansomHub and DragonForce continues to surface, Cyble reports that this latest development closely follows DragonForce's announcement of a significant expansion of its ransomware service (RaaS) operations on March 18. The DragonForce Ransomware Cartel, as part of this strategic shift, introduced the franchise-style affiliate program, whereby partners can operate and launch their own ransomware campaigns under the umbrella of DragonForce Ransomware Cartel. 

Affiliates can take advantage of this model because it allows them to maintain a high degree of operational independence while still being overseen by a central management team. Backend support is provided in a comprehensive way to all participants, including dedicated admin and client panels as well as secure data hosting environments and a resilient, always-on infrastructure that is secured with anti-DDoS mechanisms that keep the system running smoothly. This structure is designed to maintain the group's overarching operational standards as well as balance affiliate autonomy with consistency and control. 

It is worth noting that DragonForce has also introduced a series of advanced technical upgrades to its ransomware payloads targeted at ESXi, NAS, BSD, and Windows platforms along with its structural expansion. In addition, several sophisticated features have been added to the security system, including real-time encryption tracking, detached execution processes, persistent user interface messages to reinforce ransom demands, and better recovery protocols to reduce disruption. In addition, the group developed the two-pass header protection technology to enhance the cryptographic robustness of the encryption engine by using external entropy sources. This technique is also integrated with the BearSSL AES-CTR encryption protocol to enhance its cryptography. 

In addition to the technological and infrastructure advances made by DragonForce, Cyble points out that DragonForce's commitment to scale its operations at a very high level of professionalism will be reflected in these advancements. By creating a more refined and affiliate-focused ransomware ecosystem, the company hopes to attract experienced cybercriminals to collaborate with them. During the past year, DragonForce has continued to grow as a more structured and formidable player within the ransomware-as-a-service ecosystem. 

However, its recent activities indicate a broader shift in cybercriminal activity, characterized by a shift towards increasing sophistication, strategic alliances, and operational maturity in the cybercriminal underground. The apparent takeover or alignment of RansomHub with the company and the dramatic advancements in infrastructure and technology, along with the emergence of a series of threats, highlight the urgent need for the cybersecurity stakeholders to reevaluate threat models and strengthen their defensive positions. 

The most effective way for organizations, particularly those in critical sectors and high-risk regions, is to implement proactive threat intelligence strategies, enforce stringent access controls, and seriously prioritize incident response preparedness in order to counter evolving threats. With a digital landscape in which adversaries adopt business-like approaches to cause greater impact, only a cohesive and anticipatory security approach can prove robust in the face of the rising tide of cyber-extortion, which is becoming more organized and sophisticated by the day.

Fake CAPTCHAs Are the New Trap: Here’s How Hackers Are Using Them to Install Malware

 

For years, CAPTCHAs have been a familiar online hurdle—click a box, identify a few blurry images, and prove you’re human. They’ve long served as digital gatekeepers to help websites filter out bots and protect against abuse. But now, cybercriminals are turning this trusted security mechanism into a tool for deception. Security researchers are sounding the alarm over a growing threat: fake CAPTCHAs designed to trick users into unknowingly installing malware. 

These phony tests imitate the real thing, often appearing as pop-up windows or embedded verification boxes on compromised websites. At first glance, they seem harmless—just another quick click on your way to a webpage. But a single interaction can trigger a hidden chain reaction that compromises your device. The tactic is subtle but effective. By replicating legitimate CAPTCHA interfaces, attackers play on instinct. Most users are conditioned to complete CAPTCHAs without much thought. That reflexive click becomes the entry point for malicious code. 

One reported incident involved a prompt asking users to paste a code into the Windows Run dialog—an action that launched malware installation scripts. Another campaign tied to the Quakbot malware family used similar deception, embedding CAPTCHAs that initiated background downloads and executed harmful commands with a single click. These attacks, often referred to as ClickFix CAPTCHA scams, are a form of social engineering—a psychological manipulation tactic hackers use to exploit human behavior. 

In this case, attackers are banking on your trust in familiar security prompts to lower your guard. The threat doesn’t stop at just fake clicks. Some CAPTCHAs redirect users to infected web pages, while others silently copy dangerous commands to the clipboard. In the worst cases, users are tricked into pressing keyboard shortcuts that launch Windows PowerShell, allowing attackers to run scripts that steal data, disable security software, or hijack system functions. 

Experts warn that this method is particularly dangerous because it blends in so well with normal browsing activity. Unlike more obvious phishing scams, fake CAPTCHA attacks don’t rely on emails or suspicious links—they happen right where users feel safe: in their browsers. To defend against these attacks, users must remain skeptical of CAPTCHAs that ask for more than a simple click. 

If a CAPTCHA ever requests you to enter text into system tools, press unusual key combinations, or follow unfamiliar instructions, stop immediately. Those are red flags. Moreover, ensure you have reliable antivirus protection installed and keep your browser and operating system updated. Visiting lesser-known websites? Use an ad blocker or security-focused browser extension to reduce exposure to malicious scripts. 

As CAPTCHA-based scams grow more sophisticated, digital vigilance is your best defense. The next time you’re asked to “prove you’re not a robot,” it might not be your humanity being tested—but your cybersecurity awareness.

Cyber Attacks Europe hybrid attacks Russia

Russia Accused of Carrying Out Over 50 Secret Operations Across Europe

 



In the last few years since the war in Ukraine began, several European countries have experienced unusual and suspicious activities. These events include online attacks, spying, fires, and efforts to spread false information. Investigations suggest that many of these actions may be linked to Russia or groups working in its interest.

According to a report studied by journalists from a global news agency, at least 59 such incidents have taken place. These actions are believed to be part of a broader strategy known as "hybrid attacks" which mix cybercrime, sabotage, and misinformation to confuse or harm other countries without direct warfare.

Some of these incidents involved hackers breaking into politicians' accounts or important systems. In other cases, there were attempts to cause damage through arson or even plans to smuggle explosives onto cargo flights. These activities have raised serious concerns among security agencies.

Officials from NATO believe these attacks serve two purposes: to create political tension within countries and to reduce international support for Ukraine. Nations that have supported Ukraine the most— like Poland, Finland, Estonia, and Latvia—have been targeted more often.

In the Baltic Sea, mysterious shipping activity has raised suspicions of Russian involvement in damaging undersea cables and pipelines. On land, authorities in some countries have accused Russia and its close ally Belarus of creating border tensions by pushing migrants toward their borders. Fires in Lithuania and Poland have also been publicly connected to these efforts.

When asked for a response, Russian officials denied all the accusations and claimed there was no solid proof of their involvement.

In a separate investigation, journalists from a European media alliance managed to secretly join an online group linked to Russian hackers. The journalist, after gaining the group's trust, was asked to perform tasks such as putting anti-West stickers in European cities and gathering personal data about people and groups.

This group was also linked to cyberattacks targeting vital infrastructure in European and NATO member countries. They appear to be part of a growing number of hacker collectives that act on behalf of Russian interests.

A European Union representative described these operations as an invisible form of war that is becoming more common across the continent— not just in countries near Russia.

Security experts say Russian intelligence may be hiring short-term agents through online channels to carry out small-scale missions. Because these people work anonymously and are hard to trace, it's difficult to hold anyone directly responsible.

According to the Czech foreign minister, there have been around 500 suspicious cases across Europe. Of these, about 100 have been officially blamed on Russia. He added that such attacks are happening more frequently now.

Check Point Downplays Hacker’s Claims Amid Alleged Data Breach

 

A hacker using the alias “CoreInjection” has claimed responsibility for stealing what they describe as a “highly sensitive” dataset from cybersecurity firm Check Point. 
According to several media reports, the alleged stolen data includes user login credentials, employee contracts, and internal network blueprints. Despite these claims, Check Point has downplayed the incident, describing it as an outdated and isolated event involving a single account with restricted access. 

The company emphasized that no customer systems, production environments, or core security infrastructure were affected. In an official statement, Check Point clarified that the incident had occurred months ago and was addressed at the time. 

The firm criticized the hacker’s claims as misleading, suggesting they are reusing old data to create a false narrative. Cybersecurity expert Alon Gal, CTO of Hudson Rock, expressed concerns over the situation, noting that there is a strong possibility the breach involved access to a privileged administrator account—though he acknowledged that the event has yet to be fully confirmed. 

This isn’t the first time Check Point has faced such scrutiny. In 2024, its VPN software was targeted by attackers attempting to exploit it to breach corporate networks. However, those efforts were largely unsuccessful, and the company quickly issued a straightforward fix. 

While Check Point continues to reassure stakeholders that no major security risk was posed, the incident highlights the persistent threats facing even the most established cybersecurity firms.

Ukrzaliznytsia Cyberattack Disrupts Online Ticket Sales but Train Services Remain Unaffected

 

Ukraine’s national railway operator, Ukrzaliznytsia, has fallen victim to a large-scale cyberattack, severely disrupting its online ticket sales and forcing passengers to rely on physical ticket booths. The attack, which began on March 23, has caused significant delays, long queues, and overcrowding at train stations as people struggle to secure their travel arrangements. Despite the disruption to digital services, train schedules have remained unaffected, ensuring that rail transportation across the country continues without major interruptions.

In response to the attack, Ukrzaliznytsia has taken steps to mitigate the inconvenience by deploying additional staff at ticket offices to accommodate the surge in demand. However, the company acknowledged that waiting times remain long and urged passengers not to overcrowd sales points unnecessarily. To ensure that military personnel are not affected by the disruption, they have been granted the option to purchase tickets directly from train conductors. Meanwhile, civilians who had bought their tickets online before the cyberattack are advised to use the PDF copies sent to their email or arrive at the station early to seek assistance from railway officials. 

Ukrzaliznytsia confirmed the cyberattack in an official statement across multiple communication platforms, apologizing for the inconvenience caused to passengers. The company emphasized that, despite the challenges, train operations were running smoothly and schedules had not been impacted. Officials noted that prior experience with cyberattacks had helped strengthen the railway’s response mechanisms, allowing it to implement backup protocols that ensured continuity of service. 

However, online ticket sales remain unavailable as efforts continue to restore affected systems. Describing the attack as highly systematic and multi-layered, Ukrzaliznytsia stated that it was working closely with cybersecurity specialists from Ukraine’s Security Service (SBU) and the Government Computer Emergency Response Team (CERT-UA) to identify vulnerabilities and strengthen its defenses. While the company did not specify the origin of the attack, cyber threats targeting Ukrainian infrastructure have been a persistent issue since the start of Russia’s full-scale invasion. Both state agencies and private companies have faced frequent cyber incidents, highlighting the growing challenges in securing critical infrastructure. 

Despite the cyberattack, Ukrzaliznytsia remains committed to maintaining uninterrupted rail service. The company reassured passengers that its backup systems were in place to handle such incidents, ensuring that transportation across Ukraine and beyond continues without disruption. However, no specific timeline has been given for when online ticketing services will be fully restored, leaving passengers to rely on in-person ticket purchases for the foreseeable future.

600 Phishing Campaigns Emerged After Bybit Heist, Biggest Crypto Scam in History

600 Phishing Campaigns Emerged After Bybit Heist, Biggest Crypto Scam in History

Recently, the cryptocurrency suffered the largest cyberattack to date. The Bybit exchange was hit by the "largest cryptocurrency heist in history, with approximately $1.5 billion in Ethereum tokens stolen in a matter of hours," Forbes said.

After the Bybit hack, phishing campaigns steal crypto

Security vendor BforeAI said around 600 phishing campaigns surfaced after the Bybit heist, which was intended to steal cryptocurrency from its customers. In the last three weeks, after the news of the biggest crypto scam in history, BforeAI found 596 suspicious domains from 13 different countries. 

Dozens of these malicious domains mimicked the cryptocurrency exchange itself (Bybit), most using typosquatting techniques and keywords like “wallet,” “refund,” “information, “recovery,” and “check.” 

According to BforeAI, there were also “instances of popular crypto keywords such as ‘metaconnect,’ ‘mining,’ and ‘airdrop,’ as well as the use of free hosting and subdomain registration services such as Netlify, Vercel, and Pages.dev.” 

Malicious free domains used for attacks

The use of free hosting services and dynamics is a common practice in this dataset. Many phishing pages are hosted on forums that offer anonymous, quick deployment without asking for domain purchases.  Also, the highest number of verified malicious domains were registered in the UK.

After the incident, Bybit assured customers that they wouldn’t lose any money as a result. But the hackers took advantage of this situation and intentionally created a sense of anxiety and urgency via deceptive tactics like ‘fake recovery services and ‘phishing schemes.’ A few phishing websites pretended to be the “Bybit Help Center.”

The end goal was to make victims enter their crypto/Bybit passwords. A few weeks later, campaigns changed from “withdrawals, information, and refunds” through spoof Bybit sites to providing “crypto and training guides” and special rewards to trick potential investors. 

Regardless of the change in these crypto and training guides, the campaigns persevered a “connection to the earlier withdrawal scams by including ‘how to withdraw from Bybit guides,’ BforeAI explained. This results in “a flow of traffic between learning resources fakes and withdrawal phishing attempts,” it added.

Bybit has accused North Korean hackers behind the attacks, costing the firm a massive $1.5 billion in stolen crypto. The campaign has contributed to Q1 2025 with an infamous record: a $1.7 billion theft in the first quarter, the highest in history.
