Description
A host which is trusted for unconstrained delegation initiated an SMB connection to a DC using the Print System Remote Protocol. An attacker can abuse such sessions for relay attacks.
Attacker's Goals
Elevate privileges from standard domain user to domain admin.
Investigative actions
- Check if the domain controller is patched or vulnerable to the attack.
- Check if the suspected account is compromised.
- Check if the source machine is trusted for unconstrained delegation and verify that the machine's configuration should stay that way.
- Follow actions by the account and if it performed a DCSync.
