CPENT Active Directory Attacks Practice Question
An operator has discovered a computer object with Unconstrained Delegation enabled in Active Directory. How can this configuration be abused if a Domain Administrator account can be coerced to authenticate to it?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Capture the coerced Domain Admin's TGT from the machine's memory to impersonate them across the domain.
When unconstrained delegation is enabled, any service ticket sent to the machine caches the authenticating user's TGT in memory. If a Domain Admin authenticates (e.g., via PrinterBug), the operator can extract the cached TGT and perform DCSync.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Extract the NTLM hash of the domain controller directly from the SYSVOL share.
Why it's wrong here
SYSVOL does not store domain controller NTLM hashes.
- ✗
Forge a Kerberos ticket using the machine account's local SAM database.
Why it's wrong here
Machine accounts do not store KRBTGT secrets in the local SAM.
- ✗
Modify group policy objects via unauthenticated LDAP queries.
Why it's wrong here
GPO modifications require write permissions in SYSVOL and AD, not delegation extraction.
- ✓
Capture the coerced Domain Admin's TGT from the machine's memory to impersonate them across the domain.
Why this is correct
Unconstrained delegation causes the TGT to be stored in LSASS memory upon authentication, enabling full domain takeover.
