Mapping To APT1

APT1 is a Chinese threat group that has been attributed to the 2nd Bureau of the People’s Liberation Army (PLA) General Staff Department’s (GSD) 3rd Department, commonly known by its Military Unit Cover Designator (MUCD) as Unit 61398.


Disclaimer: We present this mapping to stimulate thinking about active defense options to combat this adversary, not to present all possibilities. We invite you to use this as a guide and add your own use cases for applying Shield techniques to counter each adversary action.

Note: All ATT&CK Group sub-technique mappings have been remapped to their parent technique and were derived from Group Technique mappings in ATT&CK v8.

T1059 - Command and Scripting Interpreter There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0036 - Software Manipulation A defender can manipulate the output of system commands issued to alter information the adversary might use during their activity.
T1059 - Command and Scripting Interpreter There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0036 - Software Manipulation A defender can modify the functionality of commands used to delete files so that the files are copied to a safe location before they are deleted.
