EDR-Freeze: Technical Mechanics and Forensic Artifacts Exposed
EDR-Freezeis a proof-of-concept tool that forces endpoint detection and response (EDR) or antivirus processes into a temporary “coma.” Instead of installing a vulnerable driver, it leverages legitimate Windows Error Reporting components, specifically WerFaultSecure.exe and the MiniDumpWriteDump API to pause security processes from user mode. By racing threads at just the right moment, EDR-Freeze suspends all…

Open-source DFIR Velociraptor was abused in expanding ransomware efforts
Attribution and the ransomware cocktail: Talos links the campaign to Storm-2603, a suspected China-based threat actor, citing matching TTPs like the use of ‘cmd.exe’, disabling Defender protections, creating scheduled tasks, and manipulating Group Policy Objects. The use of multiple ransomware strains in a single operation Warlock, LockBit, and Babuk also bolstered confidence in this attribution.”Talos…
