Deep Dive: Analyzing Modern Evasion Techniques Against EDR/AV Pipelines
Introduction Modern Anti-Virus (AV) and Endpoint Detection and Response (EDR) solutions no longer rely solely on simple static signatures. Instead, they implement a layered defense-in-depth pipeline that combines static scanning, in-memory inspection via the Anti-Malware Scan Interface (AMSI), and dynamic behavioral monitoring via Event Tracing for Windows (ETW). However, by understanding how these detection layers intercept execution telemetry, security researchers can analyze the structural gaps where these systems fail to correlate malicious actions. This article explores the mechanics behind common loader obfuscation pipelines and how they neutralize defensive subsystems. ...
