What is DCSync?<\/span>
DCSync is a technique used to steal the Active Directory (AD) password database by mimicking a Domain Controller (DC). It leverages the Directory Replication Service (DRS) protocol, which is used by DCs to replicate domain data. By exploiting this, an attacker can retrieve NTLM password hashes for any user in the domain.<\/p>

How Does it Work?<\/span>
To perform a DCSync attack, the attacker needs control over an account with specific replication privileges:
\u2022 Replicating Directory Changes<\/span>
\u2022 Replicating Directory Changes All<\/span><\/p>

These privileges allow the account to request password data from a DC. By default, Domain Admins and Enterprise Admins have these rights, but sometimes other accounts may also be granted these permissions.<\/p><\/div><\/div>

Steps to Perform a DCSync Attack:<\/p>

1.Identify an Account with Replication Privileges:<\/span>
Use tools like Get-DomainUser and Get-ObjectAcl to check if an account (e.g., adunn) has the necessary rights.<\/p><\/div><\/div>
