T1547:Boot or Logon AutoStart Execution
Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain a higher-level privileges on compromised systems. Operating systems may have a mechanism for automatically running a program on system boot or account logon. These mechanisms may include automatically executing programs that are place in specially designated directories or are referenced by repositories that store configuration information, such as the Windows Registry. And adversary may achieve the same goal by modifying or extending features of the kernel.
Since some boot or logon AutoStart programs run with higher privileges, an adversary may leverage these elevated privileges.
