title: LSASS Driver (T1547.008)
id: df00tech-t1547-008
status: experimental
description: "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. The LSA includes multiple DLLs associated with various security functions, all running in the context of the LSASS process (lsass.exe). Adversaries may target LSASS drivers to obtain persistence. By either replacing or adding illegitimate drivers, an adversary can use LSA operations to continuously execute malicious payloads. Known examples include Wingbird (which drops sspisrv.dll alongside lsass.exe) and Pasam (which infects the SAM DLL)."
