Practice question 176 of 498 · medium

A suspicious host requests directory replication and extracts password hashes. Which privilege boundary is being abused?

Choose the single best answer.

  1. A.SMB authentication using a stolen NTLM hash
  2. B.Replication authority associated with DCSync
  3. C.Kerberos service-ticket requests associated with Kerberoasting
  4. D.Ordinary LDAP read access to user directory attributes
Show the answer and explanation

✓ Correct answer

  • Replication authority associated with DCSync

DCSync abuses directory replication authority to obtain credential material. Ordinary LDAP reads do not grant replication of password secrets; Kerberoasting requests service tickets, and pass-the-hash uses an NTLM hash for authentication rather than directory replication.
