System Over Model, Tested: Reproducing Mythos's FreeBSD Find on Local Open-Weight Models

Mythos found a 17-year-old FreeBSD RCE; AISLE reproduced it with gpt-5.4-nano via their nano-analyzer pipeline. I ran the pipeline on two local open-weight models, gpt-oss-20b and gemma-4-31b-it. The misses recovered on re-run. The real problem was the false-positive rate, and one extra system stage cut it from 30 to 5 with the CVE still standing.

pyghidra-mcp Meets Ghidra GUI: Drive Project-Wide RE with Local AI

pyghidra-mcp v0.2.0 ships a GUI-backed mode that lets a local LLM drive a live Ghidra CodeBrowser at full project scope. Renames, plate comments, and cross-binary pivots land in real time, with every edit tagged in Ghidra's undo history while the session is alive.

How LLMs Feed Your RE Habit: Following the Use-After-Free Trail in CLFS

Dive into how LLMs and pyghidra-mcp accelerate reverse engineering by tracing a UAF vulnerability in CLFS through a patch diff.

pyghidra-mcp: Headless Ghidra MCP Server for Project-Wide, Multi-Binary Analysis

Unlock project-wide, multi-binary analysis with pyghidra-mcp, a headless Ghidra MCP server for automated, LLM-assisted reverse engineering.

Supercharging Ghidra Using Local LLMs with GhidraMCP via Ollama and OpenWeb-UI

Reverse engineering binaries often resembles digital archaeology: excavating layers of compiled code, interpreting obscured logic, and painstakingly naming countless functions and variables.
