The U.K. National Crime Agency (NCA) has unmasked the administrator and developer of the LockBit ransomware operation, revealing it to be a 31-year-old Russian national named  Dmitry Yuryevich Khoroshev . In addition, Khoroshev has been sanctioned  by the U.K. Foreign, Commonwealth and Development Office (FCD), the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), and the Australian Department of Foreign Affairs. Europol, in a  press statement , said authorities are in possession of over 2,500 decryption keys and are continuing to contact LockBit victims to offer support. Khoroshev, who went by the monikers LockBitSupp and putinkrab, has also become the subject of asset freezes and travel bans, with the U.S. Department of State offering a reward of up to $10 million for information leading to his arrest and/or conviction. Previously, the agency had  announced  reward offers of up to $15 milli...

A variant of a ransomware strain known as DJVU has been observed to be distributed in the form of cracked software. "While this attack pattern is not new, incidents involving a DJVU variant that appends the .xaro extension to affected files and demanding ransom for a decryptor have been observed infecting systems alongside a host of various commodity loaders and infostealers," Cybereason security researcher Ralph Villanueva  said . The new variant has been codenamed Xaro by the American cybersecurity firm. DJVU, in itself, is a  variant of the STOP ransomware , typically arrives on the scene masquerading as legitimate services or applications. It's also delivered as a payload of  SmokeLoader . A significant aspect of DJVU attacks is the deployment of additional malware, such as information stealers (e.g., RedLine Stealer and Vidar), making them more damaging in nature. In the latest attack chain documented by Cybereason, Xaro is propagated as an archive file from a...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The threat actors behind the  Rhysida ransomware  engage in opportunistic attacks targeting organizations spanning various industry sectors. The advisory comes courtesy of the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC). "Observed as a ransomware-as-a-service (RaaS) model, Rhysida actors have compromised organizations in education, manufacturing, information technology, and government sectors and any ransom paid is split between the group and affiliates," the agencies  said . " Rhysida actors leverage external-facing remote services, such as virtual private networks (VPNs), Zerologon vulnerability (CVE-2020-1472), and phishing campaigns to gain initial access and persistence within a network." First detected in May 2023,  Rhysida  makes use of the time-tested tactic of double extortion, demanding a ransom payment to decrypt vic...
