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 dynamic link libraries (DLLs) associated with various other security functions, all of which run in the context of the LSA Subsystem Service (LSASS) lsass.exe process. 
Adversaries may target LSASS drivers to obtain persistence. By either replacing or adding illegitimate drivers (e.g., Hijack Execution Flow), an adversary can use LSA operations to continuously execute malicious payloads.
Wingbird drops a malicious file (sspisrv.dll) alongside a copy of lsass.exe, which is used to register a service that loads sspisrv.dll as a driver. The payload of the malicious driver (located in its entry-point function) is executed when loaded by lsass.exe before the spoofed service becomes unstable and crashes.
