Pentera Introduces Cl0p Ransomware Testing for Windows and Linux Systems
Pentera has introduced Cl0p ransomware testing to its platform, enabling organisations to assess their defences against this strain on both Windows and Linux systems. This new capability allows security teams to validate their ability to prevent, detect, and respond to attacks that replicate the tactics used by the Cl0p group. Following previous support for testing against ransomware families such as Lockbit 3.0, Maze, REvil, and Conti, this addition is timely as Cl0p has remained highly active in 2025. Analysts report that Cl0p was responsible for 19% of global ransomware attacks in the first quarter of the year, with 83% of victims located in North America. The group is known for exploiting zero-day vulnerabilities to penetrate enterprise environments and exfiltrate sensitive data through extortion campaigns.
The platform’s approach to ransomware testing involves simulating each step of the attack cycle, known as the kill chain, which includes infiltration, privilege escalation, lateral movement, data extraction, and encryption activities. This methodology is designed to be safe for use in production environments, allowing organisations to evaluate their security postures without risking operational disruption. Ran Tamir, Chief Product Officer at Pentera, emphasised the importance of this capability for security leaders under pressure to prove their organisations’ ransomware readiness. With the addition of Cl0p to Pentera’s suite of ransomware campaign coverage, security teams can gain a clear and actionable view of their security posture against ransomware, identifying effective defences and potential gaps. The RansomwareReady platform simulates the tactics, techniques, and procedures used in real-world ransomware attacks, providing step-by-step remediation guidance to help organisations address security gaps discovered during testing.
