Accelerating EDR Evasion with LLM-Driven Analysis

This blog post demonstrates that modern LLMs (GPT-5.4/5.5-Cyber) can be looped with tooling such as Binary Ninja to automatically reverse-engineer and extract local EDR artifacts from Palo Alto Cortex XDR — including YARA rulesets, behavioral/DSE/BIOC rules, tree-ensemble local ML models, and encrypted CLP rule blobs — and to generate decryption/execution harnesses and simulated environments that produce actionable evasion techniques; the author warns this capability materially increases the risk of automated EDR evasion and urges broader defensive strategy adjustments.
