Learning About DCSync Attacks in Active Directory

I continued diving into exploitation techniques within Active Directory. Here are the key highlights:

1?? DCSync Attack: We'll configure and exploit it.

2?? Creating Vulnerabilities: Crafting a vulnerable user.

3?? Kerberoast: Leveraging it to obtain credentials.

4?? Pass-the-Hash: A crucial step in the attack chain.

?? The DCSync attack leverages Active Directory replication protocols, simulating a domain controller to request sensitive user data. With this method, we obtain password hashes and open doors for further attacks.

??? Permission Matters: To execute a DCSync attack, access to "Replicate Directory Changes" is essential. We'll set up the right permissions for our user, "thesync."

?? PowerShell Magic: We create "thesync" with a secure password and grant DCSync rights using PowerView.

?? Kerberoast's Role: We assign "GenericAll" permissions for "kerberoast" over "thesync."

?? Credentials Acquired: We make use of "evil-winrm" to access the victim machine and change "thesync's" password.

?? Executing DCSync: Finally, we extract system admin hashes and launch pass-the-hash attacks with "psexec."
