Federal cybersecurity agencies, including the FBI and CISA, have issued an urgent advisory regarding the escalating threat of Medusa ransomware. Since its emergence in 2021, Medusa has targeted over 300 victims across various critical infrastructure sectors, including medical, education, legal, insurance, technology, and manufacturing. The group's activities have accelerated in recent months, prompting immediate action recommendations for organizations. Medusa operates as a Ransomware-as-a-Service (RaaS) model, now recruiting affiliates from criminal forums to launch attacks, encrypt data, and extort victims worldwide.
Medusa actors leverage common ransomware tactics, including phishing campaigns and exploiting unpatched software vulnerabilities. They employ a double extortion strategy by encrypting victim data and threatening to publicly release it if the ransom is not paid. To mitigate the risk, CISA and the FBI recommend organizations update systems regularly to close known vulnerabilities, implement network segmentation to restrict lateral movement, and enable multi-factor authentication for all services. They also urge organizations to report incidents promptly to aid in tracking and combating the growing threat.

The U.S. Justice Department has indicted 12 Chinese nationals for their alleged involvement in state-linked cyber operations. The individuals include employees of the Chinese technology firm i-Soon, members of the APT27 group (also known as Emissary Panda, TG-3390, Bronze Union, and Lucky Mouse), and two officers from China's Ministry of Public Security. These indictments shed light on the hacking tools and methods allegedly employed in a global hacking scandal. The Justice Department stated that the Ministry of State Security (MSS) and Ministry of Public Security (MPS) utilized an extensive network of private companies, including i-Soon, to conduct unauthorized computer intrusions in the U.S. and elsewhere.
The U.S. DoJ charges these individuals with data theft and suppressing dissent worldwide. i-Soon, identified as one of the private companies involved, allegedly provided tools and methods to customers and hacked for the PRC (People's Republic of China). These actions highlight a significant cybersecurity concern involving state-sponsored actors and their use of private firms to conduct cyber espionage.

The Medusa ransomware operation has significantly impacted critical infrastructure sectors, affecting over 300 organizations in the United States by February 2025. According to CISA, these attacks have targeted essential services across various industries, including medical, education, legal, insurance, technology, and manufacturing. This widespread impact highlights the vulnerability of critical infrastructure and the potential for severe disruptions. The healthcare sector has been a primary target, with ransom demands ranging from $100,000 to $15 million, potentially disrupting patient care and compromising sensitive data.
Educational institutions have also been significantly affected, with 21 attacks reported in February 2025 alone. These attacks disrupt academic activities and compromise personal information of students and staff. In response, CISA, in partnership with the FBI and MS-ISAC, released a joint Cybersecurity Advisory providing tactics, techniques, and procedures (TTPs), indicators of compromise (IOCs), and detection methods associated with known Medusa ransomware activity. The advisory encourages organizations to ensure operating systems and software are up to date, segment networks to restrict lateral movement, and filter network traffic to prevent unauthorized access.

Rostislav Panev, a dual Russian-Israeli national suspected of being a key developer for the notorious LockBit ransomware operation, has been extradited to the United States. Panev was arrested in Israel in August 2024 following a U.S. provisional arrest request and has now made an initial appearance before a U.S. magistrate, where he was detained pending trial. U.S. authorities allege that Panev played a crucial role in developing the LockBit ransomware from its inception around 2019 through February 2024.
Panev is accused of developing code and maintaining infrastructure for LockBit. The U.S. Department of Justice (DoJ) stated that Panev and his co-conspirators grew LockBit into one of the most active and destructive ransomware groups globally. LockBit operators and affiliates have extracted at least $500 million in ransom payments from victims, causing billions of dollars in lost revenue and recovery costs. The complaint against Panev follows charges brought against other LockBit members, including its alleged primary creator, developer, and administrator, Dmitry Yuryevich Khoroshev, for whom the U.S. is offering a reward of up to $10 million.

The FBI has issued a warning regarding a new data extortion scam where criminals are impersonating the BianLian ransomware group. These fraudsters are sending physical letters through the United States Postal Service to corporate executives, claiming their networks have been breached. The letters demand Bitcoin payments in exchange for preventing the release of sensitive company data.
Analysis suggests these letters are fraudulent, and organizations, particularly within the US healthcare sector, are advised to report such incidents to the FBI. Security vendors, including Arctic Wolf and Guidepoint Security, have studied these letters and believe the campaign is a ruse by someone pretending to be BianLian. The letters mimic conventional ransom notes, demanding payments of between $250,000 to $350,000 within 10 days.
This activity highlights the evolving tactics of cybercriminals who are now employing postal mail to target high-profile individuals in an attempt to extort money under false pretenses. The FBI urges companies to implement internal protocols for verifying ransom demands and to remain vigilant against these deceptive practices. It’s crucial for organizations to discern fake attacks from real ones amidst the increasing complexity of cybercrime.

A new Ransomware-as-a-Service (RaaS) program, VanHelsingRaaS, has rapidly emerged as a significant threat in the cybercrime world. Launched on March 7, 2025, the program has quickly gained traction, infecting three victims within its first two weeks of operation. The service offers affiliates a control panel and a cross-platform locker, VanHelsing, which is capable of targeting a wide variety of systems, including Windows, Linux, BSD, ARM, and ESXi. This broad platform support allows affiliates to target diverse environments, increasing the potential impact of attacks.
The VanHelsingRaaS program requires a $5,000 deposit for new affiliates, while reputable affiliates can join for free. Affiliates earn 80% of the ransom payments, while the core operators receive the remaining 20%. A key restriction is the prohibition of targeting systems in the Commonwealth of Independent States (CIS). Check Point Research has identified two VanHelsing ransomware variants targeting Windows systems, but the RaaS advertisement indicates wider capabilities. This suggests the ransomware is designed to be adaptable and versatile, posing a significant threat to organizations across various industries and operating systems.

A resurgence of a fake CAPTCHA malware campaign has been observed, with threat actors compromising widely used websites across various industries. They are embedding a fake CAPTCHA challenge that redirects victims to a site triggering PowerShell code execution. This campaign exploits social engineering tactics and fake software downloads to deceive users into executing malicious scripts.
This tactic is also utilized with fake captchas which resemble legitimate sites. When users attempt to pass the captcha, they are prompted to execute code that has been copied to their clipboard. The OBSCURE#BAT malware campaign is a major cybersecurity threat to both individuals and organizations, primarily due to its ability to compromise sensitive data through advanced evasion techniques, including API hooking. This allows the malware to hide files and registry entries, making detection difficult.

Cybercriminals have allegedly stolen over $635,000 worth of Taylor Swift concert tickets by exploiting a loophole in an offshore ticketing system. Two individuals, Tyrone Rose, 20, and Shamara Simmons, 31, have been arrested and charged with grand larceny and computer tampering. The scheme involved stealing URLs for nearly 1,000 tickets to various events, including Taylor Swift's Eras Tour, Ed Sheeran concerts, Adele concerts, NBA games, and the US Open Tennis Championships, before reselling them for substantial profit.
Between June 2022 and July 2023, Rose and Simmons allegedly stole the tickets through an offshore ticket vendor and then resold them on StubHub in the US for significant profit. Rose, an employee of Sutherland Global Services, a third-party contractor for StubHub Jamaica, is accused of abusing his access to the network to find a backdoor. Prosecutors say the pair stole the tickets by allegedly intercepting approximately 350 orders from StubHub. The investigation is ongoing to determine if the Swift ticket scam was part of a wider operation.

February witnessed a record-breaking surge in ransomware attacks, fueled by the prolific activity of groups like CL0P, known for exploiting MFT vulnerabilities. The ransomware landscape is also seeing significant activity from groups like Akira and RansomHub.
Recent analysis reveals a notable development with the Black Basta and CACTUS ransomware groups, uncovering a shared BackConnect module. This module, internally tracked as QBACKCONNECT, provides extensive remote control capabilities, including executing commands and exfiltrating sensitive data. The Qilin ransomware group has also claimed responsibility for attacks on the Utsunomiya Central Clinic (UCC), a cancer treatment center in Japan, and Rockhill Women's Care, a gynecology facility in Kansas City, stealing and leaking sensitive patient data.
