CAPEC-645: Use of Captured Tickets (Pass The Ticket)
CAPEC版本: 3.9
更新日期: 2023-01-24
攻击模式描述
An adversary uses stolen Kerberos tickets to access systems/resources that leverage the Kerberos authentication protocol. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. An adversary can obtain any one of these tickets (e.g. Service Ticket, Ticket Granting Ticket, Silver Ticket, or Golden Ticket) to authenticate to a system/resource without needing the account's credentials. Depending on the ticket obtained, the adversary may be able to access a particular resource or generate TGTs for any account within an Active Directory Domain.
前提条件
- The adversary needs physical access to the victim system.
- The use of a third-party credential harvesting tool.
