Binary Reverse Engineering

Purpose

Comprehensive guide for binary reverse engineering. This skill provides the overall methodology, philosophy, and reference material. Related skills handle specific phases:

Related Skills

Skill	Purpose	Trigger Keywords
`binary-re:triage`	Fast fingerprinting	"what is this binary", "identify", "file type"
`binary-re:static-analysis`	r2 + Ghidra analysis	"disassemble", "decompile", "functions"
`binary-re:dynamic-analysis`	QEMU + GDB + Frida	"run", "execute", "debug", "trace"
`binary-re:synthesis`	Report generation	"summarize", "report", "document findings"
`binary-re:tool-setup`	Install tools	"install", "setup", "tool not found"

Note: Each skill auto-detects based on keywords. You don't need to explicitly route - just ask what you need.

Pre-Flight Verification

Before beginning any analysis, verify tooling availability:

Core Tools (Required)

rabin2 -v  # Should show version
r2 -v      # Should show version

Decompilation (Optional)

# Check r2ghidra availability
r2 -qc 'pdg?' - 2>/dev/null | grep -q Usage && echo "r2ghidra OK" || echo "r2ghidra missing - install with: r2pm -ci r2ghidra"

Dynamic Analysis Platform Check

Host Platform	Method	Setup Required
Linux x86_64	Native QEMU	`apt install qemu-user`
macOS (any)	Docker + binfmt	See `binary-re-tool-setup` skill
Windows	WSL2	Use Linux method inside WSL
