EDR Evasion Stack Helps Process Injection Slip Past Defenses

Flashpoint validated and extended research into "process parameter poisoning," an EDR evasion technique that hides payloads in Windows process startup parameters to avoid common API-based process-injection detections. Their Rust proof-of-concept demonstrated bypasses against a popular open-source EDR/XDR stack, and when combined with DLL unhooking and DLL-loading policies the technique produced no alerts in testing. Flashpoint recommends defenders inspect process parameters, monitor for thread-hijacking and abnormal code execution locations, and watch for memory permission changes; researchers have not yet observed widespread in-the-wild use.
