Representation-Confusion Attacks on LLM-Assisted Reverse Engineering

Jul 15, 2026

A new preprint introduces Representation-Confusion Attacks in Reverse Engineering (RARE), where attacker-controlled binaries can manipulate LLM-assisted reverse engineering systems by making extracted data appear as authoritative instructions or independent evidence. The authors present RARE-Guard, a defense mechanism that applies authorization and provenance controls to prevent unsafe actions and false claims. In evaluations, RARE-Guard successfully blocked all unsafe proposals and false claims while preserving legitimate analyst requests and supported claims.

Why it matters: This work reveals a significant security vulnerability in LLM-assisted reverse engineering pipelines and demonstrates a practical defense that could improve the safety and reliability of automated software analysis tools.
