# Extracting Credentials from Memory Dump

## When to Use
- During incident response to determine what credentials an attacker had access to
- When assessing the scope of credential compromise after a breach
- For identifying accounts that need immediate password resets
- When investigating lateral movement and pass-the-hash/pass-the-ticket attacks
- For recovering encryption keys or authentication tokens from process memory

## Detection Gaps & Validation
- **Credential Guard defeats LSASS scraping.** When VBS/Credential Guard is enabled, derived secrets (NTLM, Kerberos keys) live in the isolated LSAIso process and `pypykatz`/`mimikatz`/`windows.lsadump` return little or nothing. Confirm Credential Guard state before concluding "no credentials present."
- **No plaintext by default.** WDigest plaintext requires `UseLogonCredential=1` (HKLM\SYSTEM\...\WDigest); on Windows 8.1+ it is off, so an empty WDigest field is expected, not a tool failure.
- **RunAsPPL / LSA Protection** blocks process access to lsass.exe, so a memory image taken without it (or an offline dump) is required; live `windows.memmap --pid <lsass>` may yield smeared/partial data.
- **Volatility symbol mismatch = false negatives.** A wrong build/symbol table makes `windows.hashdump`/`pslist` return empty. Verify with `windows.info` and confirm the lsass PID is actually present before trusting an empty result.
