Perform Pass-the-Ticket (PtT) lateral movement by extracting Kerberos TGT/TGS tickets from LSASS memory on a compromised host and injecting them into another session to impersonate the ticket owner without knowing their password. Use during authorized post-exploitation to move laterally or escalate access via stolen Kerberos tickets, or to validate detections for Kerberos ticket theft and reuse.

Use conducting-pass-the-ticket-attack to prepare a defensive Kerberos detection checklist from [sanitized authentication-event summary]. Map the captured detection indicators—unusual 4768/4769 client hosts, ticket use from a different source address and cross-workstation reuse—to evidence questions and benign alternative explanations. Do not request tickets, credentials or memory dumps; do not extract, inject or replay tickets, impersonate users, or perform lateral movement. Make no compromise or detection-success claim from this initial checklist. Wait for my explicit confirmation before any tool, log access, command, network request or configuration change.

Conducting Pass-the-Ticket Attack
Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.
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.
When to Use

When performing scheduled security testing or auditing activities
When validating security controls through hands-on testing
Prerequisites
Familiarity with red teaming concepts and tools
Access to a test or lab environment for safe execution
Python 3.8+ with required dependencies installed
Appropriate authorization for any testing activities
