# Workflows: Zerologon Exploitation
|
|
|
|
## Exploitation Workflow
|
|
|
|
```
|
|
┌─────────────────────────────────────────────────────────────────┐
|
|
│ ZEROLOGON EXPLOITATION WORKFLOW │
|
|
├─────────────────────────────────────────────────────────────────┤
|
|
│ │
|
|
│ 1. RECONNAISSANCE │
|
|
│ ├── Identify domain controllers (DNS SRV records) │
|
|
│ ├── Verify network access to DC (TCP 135, RPC) │
|
|
│ └── Check patch status with zerologon_tester.py │
|
|
│ │
|
|
│ 2. EXPLOITATION │
|
|
│ ├── Run CVE-2020-1472 exploit (~256 attempts, ~3 seconds) │
|
|
│ ├── DC machine account password set to empty │
|
|
│ └── Verify exploitation success │
|
|
│ │
|
|
│ 3. CREDENTIAL EXTRACTION │
|
|
│ ├── DCSync with empty hash (secretsdump.py -no-pass) │
|
|
│ ├── Extract Administrator NTLM hash │
|
|
│ ├── Extract krbtgt hash (for Golden Ticket) │
|
|
│ └── Extract all domain user hashes │
|
|
│ │
|
|
│ 4. DOMAIN ACCESS │
|
|
│ ├── Pass-the-Hash as Administrator │
|
|
│ ├── Access any domain system │
|
|
│ └── Create Golden Ticket for persistence │
|
|
│ │
|
|
│ 5. RESTORATION (CRITICAL) │
|
|
│ ├── Restore DC machine account password immediately │
|
|
│ ├── Verify AD replication is functioning │
|
|
│ └── Document exploitation and restoration timestamps │
|
|
│ │
|
|
└─────────────────────────────────────────────────────────────────┘

## Impact Assessment
|
|
|
|
```
|
|
Zerologon Impact Chain
|
|
│
|
|
├── DC Machine Account Password Reset to Empty
|
|
│ ├── AD Replication BREAKS (secrets no longer sync)
|
|
│ ├── DNS may stop functioning
|
|
│ ├── Group Policy stops processing
|
|
│ └── Kerberos ticket validation fails
|
|
│
|
|
├── DCSync with Empty Hash
|
|
│ ├── ALL domain password hashes extracted
|
|
│ ├── krbtgt hash = Golden Ticket capability
|
|
│ └── Service account hashes = lateral movement
|
|
│
|
|
└── Full Domain Compromise
|
|
├── Administrator access to all systems
|
|
├── Ability to create/modify any account
|
|
└── Complete control over Active Directory
|
|
```
|
|
|
|
**RED TEAM WARNING**: Always restore the DC machine account password immediately after exploitation. Failing to do so will cause Active Directory to break, potentially causing a production outage.
