EDR Bypass Technique Uses Windows Functions to Put Antivirus Tools to Sleep

This article discusses new techniques for bypassing Endpoint Detection and Response (EDR) systems using Windows error reporting functions, specifically the EDR-Freeze exploit. This approach allows threat actors to suspend antivirus processes without installing vulnerable drivers, making detection more difficult. #EDRFrozen #MiniDumpWriteDump

Keypoints

Threat actors are using innovative methods to evade EDR and antivirus protections on Windows systems.
The EDR-Freeze exploit leverages Windows Error Reporting and the MiniDumpWriteDump function to suspend security processes.
Researchers have reverse-engineered Windows components like WerFaultSecure to carry out these bypass techniques.
The new approach avoids the risks associated with BYOVD (Bring Your Own Vulnerable Driver) attacks, reducing system disturbances.
A race condition attack can be executed using CreateProcessAsPPL and process suspension techniques to maintain control over target systems.
