Conducting Pass-the-Ticket Attack
Overview
Pass-the-Ticket (PtT) is a lateral movement technique that uses stolen Kerberos tickets (TGT or TGS) to authenticate to services without knowing the user's password. By extracting Kerberos tickets from memory (LSASS) on a compromised host, an attacker can inject those tickets into their own session to impersonate the ticket owner and access resources as that user.
MITRE ATT&CK Mapping
- T1550.003 - Use Alternate Authentication Material: Pass the Ticket
- T1003.001 - OS Credential Dumping: LSASS Memory
- T1558 - Steal or Forge Kerberos Tickets
- T1021.002 - Remote Services: SMB/Windows Admin Shares
Implementation Steps
Phase 1: Ticket Extraction
- Gain local admin access on target workstation
- Dump Kerberos tickets from LSASS memory using Mimikatz or Rubeus
- Export tickets in .kirbi format (Mimikatz) or base64 (Rubeus)
- Identify high-value tickets (Domain Admin TGTs, service tickets to critical systems)
Phase 2: Ticket Injection
- Purge existing Kerberos tickets from attacker session
- Import/inject stolen ticket into current session
- Verify ticket is loaded and valid
- Access target resources using injected ticket
Phase 3: Lateral Movement
- Access remote systems using the stolen ticket identity
- Perform actions as the impersonated user
- Collect additional credentials from accessed systems
- Document evidence of successful lateral movement
Tools and Resources
| Tool | Purpose | Command |
|---|---|---|
| Mimikatz | Ticket export/import | sekurlsa::tickets /export, kerberos::ptt |
| Rubeus | Ticket dumping and injection | dump, ptt, tgtdeleg |
| Impacket ticketConverter | Convert between formats | ticketConverter.py ticket.kirbi ticket.ccache |

Detection Indicators
- Event ID 4768 with unusual client addresses
- Event ID 4769 service ticket requests from unexpected hosts
- TGT usage from different IP than the TGT was issued to
- Multiple authentications from same ticket across different workstations
Validation Criteria
- Kerberos tickets extracted from compromised host
- Tickets injected into attacker session
- Lateral movement demonstrated using stolen tickets
- Evidence captured for reporting
