This Thursday I'm joining

's live to put LLM-powered reverse-engineering workflows head-to-head. We compare Binja's client-side LLM integrations vs. fully headless agents Expect practical workflow comparisons, lots of fun, and a bit of chaos.

Agentic reverse engineering can do a lot, but obfuscation still breaks many analysis workflows in malware and commercial software. If you want to learn how to build & steer automation for analyzing protected code, check out my training at

Recently my RE workflow moved into sandboxed VMs where agents have full control over the environment. I needed an MCP server that runs headless in the same sandbox and exposes way more of the
#BinaryNinja
API than others. Here's the release:

The new version of my
#BinaryNinja
plugin Obfuscation Analysis (v1.2) adds recursive function inlining in the decompiler. It collapses call-heavy code into a single function; analysis, constant propagation, DCE and other analyses work across boundaries.

Based on research by
@mrphrazer.bsky.social
and
@mu00d8.bsky.social
, presented at RECon 2024, I used graph theory code from Ghidra's codebase to select the order in which functions are sent to the LLM, ensuring as much context as possible is retained. The script is aptly named GhidrAI! 5/n
