Signatures

Privilege Escalation

T1134 opens_thread_token: Opens the access token associated with a thread
T1134 opens_process_token: Opens the access token associated with a process

Defense Evasion

T1497 antidbg_windows: Checks for open windows typical for debuggers and forensic tools
T1497 antidbg_setinformationthread: Attempts to evade debugger using NtSetInformationThread
T1497.001 antivm_generic_bios: Checks the BIOS version, possibly for anti-virtualization
