Developers using the AI-powered coding assistant Cursor have fallen victim to a sophisticated crypto heist, losing an estimated $500,000. The incident involved a malicious extension, disguised as a legitimate tool for Solidity developers, which was distributed through the Open VSX marketplace. This marketplace, which serves as a source for extensions for AI development tools like Cursor, does not undergo the same stringent security checks as other marketplaces, creating a vulnerability that attackers exploited. The fake extension, titled "Solidity Language," managed to gain tens of thousands of downloads, likely boosted by bot activity, and successfully deceived even experienced users.

The malicious extension operated by silently executing PowerShell scripts and installing remote access tools on the victim's computer. Upon installation, the extension contacted a command-and-control server to download and run these harmful scripts. The attackers then leveraged the installed remote access application, ScreenConnect, to gain full control of the compromised system. This allowed them to upload additional malicious payloads, specifically targeting the developer's crypto wallet passphrases and ultimately siphoning off approximately $500,000 in cryptocurrency assets. The attackers also employed algorithm tricks to ensure the malicious extension ranked highly in search results, further increasing its visibility and the likelihood of it being downloaded by unsuspecting developers.

This incident highlights a growing trend of attacks that leverage vulnerabilities within the open-source software ecosystem. While the Solidity Language extension itself offered no actual functionality, its deceptive appearance and elevated search ranking allowed it to trick users into installing malware. Security experts are urging developers to exercise extreme caution when installing extensions, emphasizing the importance of verifying extension authors and using robust security tools. The weaponization of AI-enhanced development tools serves as a stark reminder that the very tools designed to enhance productivity can be turned into vectors for significant financial loss if not handled with the utmost security awareness.

The Rare Werewolf APT group, also known as Librarian Ghouls and Rezet, has been actively targeting Russian enterprises and engineering schools since at least 2019, with activity continuing through May 2025. This advanced persistent threat group distinguishes itself by primarily utilizing legitimate third-party software instead of developing its own malicious tools. The attacks are characterized by the use of command files and PowerShell scripts to establish remote access to compromised systems, steal credentials, and deploy the XMRig cryptocurrency miner. The campaign has impacted hundreds of Russian users, with additional infections reported in Belarus and Kazakhstan.

The group's initial infection vector typically involves targeted phishing emails containing password-protected archives with executable files disguised as official documents or payment orders. Once the victim opens the attachment, the attackers deploy a legitimate tool called 4t Tray Minimizer to obscure their presence on the compromised system. They also use tools like Defender Control to disable antivirus software and Blat, a legitimate utility, to send stolen data via SMTP. The attackers actively refine their tactics and a new wave of attacks emerged immediately after a slight decline in December 2024.

A key aspect of the Rare Werewolf APT's strategy involves the use of a Windows batch script that launches a PowerShell script, scheduling the victim system to wake up at 1 AM local time and providing a four-hour window for remote access via AnyDesk. The machine is then shut down at 5 AM through a scheduled task, minimizing the chance of detection. The attackers also collect information about available CPU cores and GPUs to optimally configure the crypto miner. Besides cryptomining, the group has also been known to steal sensitive documents, passwords, and compromise Telegram accounts.

A massive database containing over 184 million unique login credentials has been discovered online by cybersecurity researcher Jeremiah Fowler. The unprotected database, which amounted to approximately 47.42 gigabytes of data, was found on a misconfigured cloud server and lacked both password protection and encryption. Fowler, from Security Discovery, identified the exposed Elastic database in early May and promptly notified the hosting provider, leading to the database being removed from public access.

The exposed credentials included usernames and passwords for a vast array of online services, including major tech platforms like Apple, Microsoft, Facebook, Google, Instagram, Snapchat, Roblox, Spotify, WordPress, and Yahoo, as well as various email providers. More alarmingly, the data also contained access information for bank accounts, health platforms, and government portals from numerous countries, posing a significant risk to individuals and organizations. The authenticity of the data was confirmed by Fowler, who contacted several individuals whose email addresses were listed in the database, and they verified that the passwords were valid.

The origin and purpose of the database remain unclear, with no identifying information about its owner or collector. The sheer scope and diversity of the login details suggest that the data may have been compiled by cybercriminals using infostealer malware. Jeremiah Fowler described the find as "one of the most dangerous discoveries" he has found in a very long time. The database's IP address pointed to two domain names, one of which was unregistered, further obscuring the identity of the data's owner and intended use.

SK Telecom, South Korea's largest mobile network operator, revealed a significant data breach in April 2025 that exposed the USIM data of 27 million subscribers. The company first detected malware on its networks on April 19, 2025, and responded by isolating the compromised servers. Investigations have since revealed the breach began as far back as June 15, 2022, with attackers deploying a web shell on one of SK Telecom's servers. This initial compromise provided a foothold in the network allowing them to execute commands and deploy additional malware payloads across multiple servers.

The attackers were able to steal a wide array of sensitive information, including users’ IMSI numbers, USIM authentication keys, network usage data, text messages, and contacts stored on SIM cards. A joint investigative committee comprising the South Korean government and SK Telecom discovered 25 separate backdoor programs on the company’s servers. Due to the undetected nature of the breach for nearly three years, the intruders were able to implant backdoors tailored to different malicious functions. SK Telecom only began logging server activity on December 31, 2024, creating a data void between June 15, 2022, and December 31, 2024, making it difficult to ascertain what data was exfiltrated or what malicious operations were executed during that time.

The breach has affected an estimated 26.95 million SK Telecom users, prompting the company to take immediate action. SK Telecom has suspended the onboarding of new customers and announced it will begin notifying all affected individuals to replace their SIM cards and adopt enhanced security measures. To mitigate the risks associated with SIM-swapping attacks, SK Telecom announced it would issue replacement SIM cards to all affected customers, while also implementing stricter safeguards to prevent unauthorized number transfers. The company also confirmed that USIM records for its entire subscriber base of 29 million people were exposed.

A sophisticated cyberattack campaign is exploiting the popularity of the generative AI service Kling AI to distribute malware through fake Facebook ads. Check Point Research uncovered the campaign, which began in early 2025. The attackers created convincing spoof websites mimicking Kling AI's interface, luring users with the promise of AI-generated content. These deceptive sites, promoted via at least 70 sponsored posts on fake Facebook pages, ultimately trick users into downloading malicious files.

Instead of delivering the promised AI-generated images or videos, the spoofed websites serve a Trojan horse. This comes in the form of a ZIP archive containing a deceptively named .exe file, designed to appear as a .jpg or .mp4 file through filename masquerading using Hangul Filler characters. When executed, this file installs a loader with anti-analysis features that disables security tools and establishes persistence on the victim's system. This initial loader is followed by a second-stage payload, which is the PureHVNC remote access trojan (RAT).

The PureHVNC RAT grants attackers remote control over the compromised system and steals sensitive data. It specifically targets browser-stored credentials and session tokens, with a focus on Chromium-based browsers and cryptocurrency wallet extensions like MetaMask and TronLink. Additionally, the RAT uses a plugin to capture screenshots when banking apps or crypto wallets are detected in the foreground. Check Point Research believes that Vietnamese threat actors are likely behind the campaign, as they have historically employed similar Facebook malvertising techniques to distribute stealer malware, capitalizing on the popularity of generative AI tools.

Cybercriminals are exploiting the popularity of AI by distributing the 'Noodlophile' information-stealing malware through fake AI video generation tools. These deceptive websites, often promoted via Facebook groups, lure users with the promise of AI-powered video creation from uploaded files. Instead of delivering the advertised service, users are tricked into downloading a malicious ZIP file containing an executable disguised as a video file, such as "Video Dream MachineAI.mp4.exe." This exploit capitalizes on the common Windows setting that hides file extensions, making the malicious file appear legitimate.

Upon execution, the malware initiates a multi-stage infection process. The deceptive executable launches a legitimate binary associated with ByteDance's video editor ("CapCut.exe") to run a .NET-based loader. This loader then retrieves a Python payload ("srchost.exe") from a remote server, ultimately leading to the deployment of Noodlophile Stealer. This infostealer is designed to harvest sensitive data, including browser credentials, cryptocurrency wallet information, and other personal data.

Morphisec researchers, including Shmuel Uzan, warn that these campaigns are attracting significant attention, with some Facebook posts garnering over 62,000 views. The threat actors behind Noodlophile are believed to be of Vietnamese origin, with the developer's GitHub profile indicating a passion for malware development. The rise of AI-themed lures highlights the growing trend of cybercriminals weaponizing public interest in emerging technologies to spread malware, impacting unsuspecting users seeking AI tools for video and image editing.

A new malware campaign is exploiting the hype surrounding artificial intelligence to distribute the Noodlophile Stealer, an information-stealing malware. Morphisec researcher Shmuel Uzan discovered that attackers are enticing victims with fake AI video generation tools advertised on social media platforms, particularly Facebook. These platforms masquerade as legitimate AI services for creating videos, logos, images, and even websites, attracting users eager to leverage AI for content creation.

Posts promoting these fake AI tools have garnered significant attention, with some reaching over 62,000 views. Users who click on the advertised links are directed to bogus websites, such as one impersonating CapCut AI, where they are prompted to upload images or videos. Instead of receiving the promised AI-generated content, users are tricked into downloading a malicious ZIP archive named "VideoDreamAI.zip," which contains an executable file designed to initiate the infection chain.

The "Video Dream MachineAI.mp4.exe" file within the archive launches a legitimate binary associated with ByteDance's CapCut video editor, which is then used to execute a .NET-based loader. This loader, in turn, retrieves a Python payload from a remote server, ultimately leading to the deployment of the Noodlophile Stealer. This malware is capable of harvesting browser credentials, cryptocurrency wallet information, and other sensitive data. In some instances, the stealer is bundled with a remote access trojan like XWorm, enabling attackers to gain entrenched access to infected systems.

North Korean hackers, identified as the Contagious Interview APT group, are running a sophisticated malware campaign targeting individuals seeking employment in the cryptocurrency sector. Silent Push threat analysts have uncovered the operation, revealing that the group, also known as Famous Chollima and a subgroup of Lazarus, is using three front companies—BlockNovas LLC, Angeloper Agency, and SoftGlide LLC—to spread malicious software. These companies are being used to lure unsuspecting job applicants into downloading malware through fake job interview opportunities, marking an evolution in the group's cyber espionage and financial gain tactics.

The campaign involves the distribution of three distinct malware strains: BeaverTail, InvisibleFerret, and OtterCookie. Job seekers are enticed with postings on various online platforms, including CryptoJobsList, CryptoTask, and Upwork. Once an application is submitted, the hackers send what appear to be legitimate interview-related files containing the malware. The attackers are also using AI-generated images to create employee profiles for these front companies, specifically using Remaker AI to fabricate realistic personas, enhancing the credibility of their fraudulent operations and making it harder for job seekers to differentiate between genuine and malicious opportunities.

The use of these front companies and AI-generated profiles signifies a new escalation in the tactics employed by Contagious Interview. The malware, once installed, allows hackers to remotely access infected computers and steal sensitive data. The campaign leverages legitimate platforms like GitHub and various job boards to further enhance its deceptive nature. Silent Push's analysis has successfully traced the malware back to specific websites and internet addresses used by the hackers, including lianxinxiao[.]com, and uncovered a hidden online dashboard monitoring suspected BeaverTail websites, providing valuable insights into the operational infrastructure of this North Korean APT group.
