Do you know how attackers hide inside Active Directory?

Itโ€™s called persistence. Attackers often want to stay in your environment long-term without being spotted – which means being a loud Domain Admin is usually not the plan.

To spot this, you need to understand what options attackers have and how ACLs + object relationships can create an escalation path they can quietly keep โ€œreadyโ€ for later.

A few examples:

1๏ธโƒฃ ๐—”๐—ฑ๐—บ๐—ถ๐—ป๐—ฆ๐——๐—›๐—ผ๐—น๐—ฑ๐—ฒ๐—ฟ

AdminSDHolder is an AD container whose ACL is used as a ๐˜๐—ฒ๐—บ๐—ฝ๐—น๐—ฎ๐˜๐—ฒ for privileged accounts and groups.If an attacker modifies permissions here, they can gain powerful access without joining privileged groups – and thatโ€™s exactly why itโ€™s dangerous.

2๏ธโƒฃ ๐——๐—–๐—ฆ๐—ต๐—ฎ๐—ฑ๐—ผ๐˜„

DCShadow is based on privileges that allow an account to ๐—ฟ๐—ฒ๐—ฝ๐—น๐—ถ๐—ฐ๐—ฎ๐˜๐—ฒ changes to AD from a compromised โ€œrogue domain controllerโ€. These include:

โ€ข Add/Remove Replica In Domain

โ€ข DS-Replication-Synchronize

โ€ข DS-Replication-Manage-Topology

3๏ธโƒฃ ๐——๐—–๐—ฆ๐˜†๐—ป๐—ฐ

DCSync is based on privileges that allow an account to ๐—ฟ๐—ฒ๐—ฝ๐—น๐—ถ๐—ฐ๐—ฎ๐˜๐—ฒ AD database data (including secrets). These include:

โ€ข Replicating Directory Changes

โ€ข Replicating Directory Changes All

The tricky part is that some tools and service accounts may legitimately need replication rights or special ACLs – which makes them high-value targets. Theyโ€™re powerful, but not always obvious.

๐Ÿšจ You can check these settings occasionally, sure. But in real environments the bigger problem is ๐—ฑ๐—ฟ๐—ถ๐—ณ๐˜: changes happen over time and nobody notices.

โœ… Thatโ€™s one reason I started collaborating with Forestall, specifically their ๐—œ๐—ฆ๐—ฃ๐—  ๐—ฝ๐—น๐—ฎ๐˜๐—ณ๐—ผ๐—ฟ๐—บ – it helps you detect these persistence methods (ACL changes, replication rights, risky relationships) and ๐—ฎ๐—น๐—ฒ๐—ฟ๐˜ ๐˜†๐—ผ๐˜‚ ๐—ฒ๐—ฎ๐—ฟ๐—น๐˜†.
