SID-History Injection
Where this stands
One published detection covers this technique. Every one is unverified — no rule on Siemphony has been executed against real telemetry.
What the technique is
Adversaries may use SID-History Injection to escalate privileges and bypass access controls. The Windows security identifier (SID) is a unique value that identifies a user or group account. SIDs are used by Windows security in both security descriptors and access tokens. An account can hold additional SIDs in the SID-History Active Directory attribute, allowing inter-operable account migration between domains (e.g., all values in SID-History are included in access tokens). With Domain Administrator (or equivalent) rights, harvested or well-known SID values may be inserted into SID-History to enable impersonation of arbitrary users/groups such as Enterprise Administrators. This manipulation may result in elevated access to local resources and/or access to otherwise inaccessible domains via lateral movement techniques such as Remote Services, SMB/Windows Admin Shares, or Windows Remote Management.

- AN0383
Detection of unauthorized modification of Active Directory SID-History attributes to escalate privileges. This chain involves: (1) privileged operations or API calls to DsAddSidHistory or related AD modification functions, (2) observed attribute changes in SID-History (Event ID 5136), (3) new logon sessions where the token includes unexpected or privileged SID-History values, and (4) follow-on resource access using elevated privileges derived from SID-History injection.
