Ransomware attacks continue to evade defenses despite significant security investments. Double extortion tactics are prevalent, with some actors focusing solely on data theft and extortion. The Picus Security Blue Report 2025 reveals a decline in prevention effectiveness, particularly in data exfiltration, leaving organizations vulnerable to ransomware attacks. The report highlights that both known and emerging ransomware strains successfully bypass defenses, emphasizing the need for continuous validation of security measures. Key gaps in malware delivery, detection, data exfiltration, and endpoint protection are identified, showing that attackers exploit these weaknesses to maintain effectiveness.

Picus Security Blue Report 2025 reveals declining ransomware prevention effectiveness
The Picus Security Blue Report 2025 highlights a significant decline in ransomware prevention effectiveness, with data exfiltration prevention dropping to 3%. Both known and emerging ransomware strains are successfully bypassing defenses, exploiting gaps in malware delivery, detection, and endpoint protection. The report emphasizes the need for continuous validation of security measures to ensure readiness against evolving ransomware threats. The report draws on over 160 million Breach and Attack Simulation (BAS) results, showing that prevention effectiveness fell from 69% in 2024 to 62% in 2025. Key ransomware families like BlackByte, BabLock, and Maori continue to evade defenses, while emerging strains such as FAUST, Valak, and Magniber also pose significant threats.
