aiqbench analysis

This experiment demonstrates that advanced LLMs like Claude Opus 5 often bypass static binary protections by shifting to dynamic emulation rather than successfully deobfuscating hardened code. The findings highlight a critical reliability gap for AI agents in security contexts, where they may find functional workarounds without verifying the integrity of the underlying protection mechanisms. For incident responders, this underscores that layered obfuscation still necessitates runtime analysis even when static inspection appears confusing or failed.

Claude Opus 5 Routes Around Obfuscated Binaries Instead of Defeating the Protection

Claude Opus 5 did not crack hardened binaries in a reverse-engineering experiment. Instead, it sought easier ways to recover hidden information, showing AI-assisted analysis can be capable yet unreliable. The test was not a malware outbreak. It used stripped AArch64 binaries containing hidden strings, then placed an autonomous coding agent in a sandbox with disassembly, emulation, and scripting tools. Its assignment was to recover the strings and deliver a script.…
