# Welcome

## NullFang

**NullFang** is a **stealth-optimized SMB reconnaissance tool** built in Go for **offensive security operations**. It delivers:

* **High-speed pattern matching** (regex, binary carving, leet-speak detection) across:\
  ✓ Office documents (OLE/XML structures)\
  ✓ Configuration files (JSON/YAML/ENV)\
  ✓ Database exports (SQL, NoSQL dumps)\
  ✓ Compressed archives (ZIP, RAR embedded objects)
* **Operational security by design**:\
  ▶ **No-copy mode** avoids file I/O operations, evading EDR file handles and USN journal logging\
  ▶ **In-memory analysis** minimizes disk/network artifacts\
  ▶ **Controlled execution timing** to blend with normal SMB traffic
* **Red Team-specific advantages**:\
  ✓ Maps **User→Host→File→Privilege** relationships\
  ✓ Identifies **lateral movement paths** via credential/configuration patterns\
  ✓ Generates **forensic noise assessments** pre-operation
