# Binary Analysis Skill

This skill provides step-by-step procedures for static binary reverse engineering and analysis.

## Core Capabilities

1. **PE/ELF Structure Parsing**:
   Inspect headers, sections, exported symbols, imported DLLs, and EntryPoint:
   ```bash
   python .agents/tools/re-toolkit/cli.py parse-pe <target_file> --json
   ```

2. **Instruction Disassembly**:
   Disassemble raw binary or specific section offsets:
   ```bash
   python .agents/tools/re-toolkit/cli.py disasm <target_file> --offset 0x1000 --length 128 --arch x86_64
   ```

3. **Pattern Scanning (AOB Scanner)**:
   Locate code patterns across memory sections with wildcards:
   ```python
   from pe_parser import PEParser
   from disasm import pattern_scan

   with open("target.exe", "rb") as f:
       data = f.read()
   offsets = pattern_scan(data, "48 89 5c 24 ?? 55 48 83 ec")
   print("Found offsets:", [hex(o) for o in offsets])
   ```

4. **Instruction Micro-Emulation**:
   Test and execute arithmetic / logic routines in isolation without running target binaries:
   ```bash
   python .agents/tools/re-toolkit/cli.py emulate --code "B82A000000505BC3"
   ```
