Behind the Scenes of Matveev's Ransomware Empire: Tactics and Team

Behind the Scenes of Matveev's Ransomware Empire: Tactics and Team

Dec 19, 2023 Ransomware / Russian Hackers
Cybersecurity researchers have shed light on the inner workings of the ransomware operation led by Mikhail Pavlovich Matveev, a Russian national who was  indicted by the U.S. government  earlier this year for his alleged role in launching thousands of attacks across the world. Matveev, who resides in Saint Petersburg and is known by the aliases Wazawaka, m1x, Boriselcin, Uhodiransomwar, Orange, and waza, is alleged to have played a crucial part in the development and deployment of LockBit, Babuk, and Hive ransomware variants since at least June 2020. "Wazawaka and his team members prominently exhibit an insatiable greed for ransom payments, demonstrating a significant disregard for ethical values in their cyber operations," Swiss cybersecurity firm PRODAFT  said  in a comprehensive analysis shared with The Hacker News. "Employing tactics that involve intimidation through threats to leak sensitive files, engaging in dishonest practices, and persisting in retaining fil
Third Flaw Uncovered in MOVEit Transfer App Amidst Cl0p Ransomware Mass Attack

Third Flaw Uncovered in MOVEit Transfer App Amidst Cl0p Ransomware Mass Attack

Jun 16, 2023 Cyber Attack / Ransomware
Progress Software on Thursday  disclosed  a third vulnerability impacting its MOVEit Transfer application, as the Cl0p cybercrime gang deployed extortion tactics against affected companies. The  new flaw , which is being tracked as CVE-2023-35708 , also concerns an SQL injection vulnerability that "could lead to escalated privileges and potential unauthorized access to the environment." The company is urging its customers to disable all HTTP and HTTPs traffic to MOVEit Transfer on ports 80 and 443 to safeguard their environments while a fix is being prepared to address the weakness. The cloud managed file transfer solution has been fully patched. The revelation comes a week after Progress  divulged  another set of SQL injection vulnerabilities ( CVE-2023-35036 ) that it said could be weaponized to access the application's database content. The vulnerabilities join  CVE-2023-34362 , which was  exploited  as a zero-day by the Clop ransomware gang in data theft attacks
ESXiArgs Ransomware Hits Over 500 New Targets in European Countries

ESXiArgs Ransomware Hits Over 500 New Targets in European Countries

Feb 16, 2023 Cyber Attack / Ransomware
More than 500 hosts have been newly compromised en masse by the ESXiArgs ransomware strain, most of which are located in France, Germany, the Netherlands, the U.K., and Ukraine. The  findings  come from attack surface management firm Censys, which  discovered  "two hosts with strikingly similar ransom notes dating back to mid-October 2022, just after ESXi versions 6.5 and 6.7 reached end of life." The first set of infections dates back to October 12, 2022, much earlier than when the campaign  began to gain traction  at the start of February 2023. Then on January 31, 2023, the ransom notes on the two hosts are said to have been updated with a revised version that matches the ones used in the current wave. Some of the crucial differences between the two ransom notes include the use of an onion URL instead of a Tox chat ID, a Proton Mail address at the bottom of the note, and a lower ransom demand (1.05 Bitcoin vs. 2.09 Bitcoin). "Each variant of the ransom notes from

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo
Cacti Servers Under Attack as Majority Fail to Patch Critical Vulnerability

Cacti Servers Under Attack as Majority Fail to Patch Critical Vulnerability

Jan 14, 2023 Server Security / Patch Management
A majority of internet-exposed Cacti servers have not been patched against a recently patched critical security vulnerability that has come under active exploitation in the wild. That's according to attack surface management platform Censys, which  found  only 26 out of a total of 6,427 servers to be running a  patched version  of Cacti (1.2.23 and 1.3.0). The  issue  in question relates to  CVE-2022-46169  (CVSS score: 9.8), a combination of authentication bypass and command injection that enables an unauthenticated user to execute arbitrary code on an affected version of the open-source, web-based monitoring solution. Details about the flaw, which impacts versions 1.2.22 and below, were first revealed by SonarSource. The flaw was reported to the project maintainers on December 2, 2022. "A hostname-based authorization check is not implemented safely for most installations of Cacti," SonarSource researcher Stefan Schiller  noted  earlier this month, adding "uns
