Attackers Bypass Next-Gen EDR Using Windows Error Reporting and io_uring Techniques
By
HackMoN Ai
Summary
This article examines advanced EDR (Endpoint Detection and Response) bypass techniques used by attackers, focusing on two specific methods: exploiting Windows Error Reporting (WER) and leveraging io_uring for asynchronous I/O operations. It details how attackers are moving away from kernel-level driver exploits toward stealthier user-mode attacks that leave minimal forensic footprints, challenging the effectiveness of next-gen endpoint security solutions.

· 2 pulledEndpoint Detection and Response (EDR) systems have become the cornerstone of modern enterprise security, offering deep visibility into endpoint activities through behavioral analysis and system call monitoring.
A new wave of sophisticated evasion techniques is challenging the effectiveness of these defenses, with attackers shifting from kernel-level driver exploits to stealthy user-mode attacks and asynchronous I/O operations that leave minimal forensic footprints.
