Ransomware Under Pressure: Tactics, Techniques, and Procedures in a Shifting Threat Landscape
Ransomware remains a significant threat despite indicators of declining profitability due to improved defenses, increased recovery capabilities, and lower ransom payments. The ransomware-as-a-service (RaaS) ecosystem has consolidated around established brands like Qilin and Akira following disruptions to groups such as LockBit and ALPHV, resulting in record victim postings on data leak sites in 2025. Analysis of 2025 incidents shows vulnerability exploitation in VPNs and firewalls as the most common initial access vector, with 77 percent of intrusions involving data theft extortion and 43 percent targeting virtualization infrastructure.
Why it matters: Security teams need to prioritize patching VPNs and firewalls, implementing data exfiltration controls, and hardening virtualization environments, as these remain primary targets despite the shifting threat landscape.
