Adversaries may modify or add LSASS drivers to obtain persistence on compromised systems. The Windows security subsystem is a set of components that manage and enforce the security policy for a computer or domain. The Local Security Authority (LSA) is the main component responsible for local security policy and user authentication.

If this is happening now

Checklists and playbooks to open while the alert is still live.

Playbook for this stage

Suspicious execution on an endpoint

An EDR alert, an unexplained process, or a user reporting something odd.

Playbook for this stage

Cloud account compromise

Impossible travel, an unrecognised inbox rule, or a reported invoice-fraud attempt.

how MITRE says to see it

Detect unauthorized LSASS driver persistence via LSA plugin abuse (Windows)

Unauthorized creation or modification of DLLs loaded by LSASS, abnormal registry values under LSA extensions, and anomalous DLL load activity into the lsass.exe process context, correlated during boot or logon events.

what reduces it

M1043 Credential Access Protection. On Windows 10 and Server 2016, enable Windows Defender Credential Guard to run lsass.exe in an isolated virtualized environment without any device drivers.
M1025 Privileged Process Integrity. On Windows 8.1 and Server 2012 R2, enable LSA Protection by setting the Registry key `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\RunAsPPL` to `dword:00000001`. LSA Protection ensures that LSA plug-ins and drivers are only loaded if they are digitally signed with a Microsoft signature and adhere to the Microsoft Security Development Lifecycle (SDL) process guidance.
M1044 Restrict Library Loading. Ensure safe DLL search mode is enabled `HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\SafeDllSearchMode` to mitigate risk that lsass.exe loads a malicious code library.
