cyberstrikeus T1630.002 File Deletion
Sub-technique of: T1630
High-Level Description
Adversaries may wipe a device or delete individual files in order to manipulate external outcomes or hide activity. An application must have administrator access to fully wipe the device, while individual files may not require special permissions to delete depending on their storage location.

The impact file deletion will have depends on the type of data as well as the goals and objectives of the adversary, but can include deleting update files to evade detection or deleting attacker-specified files for impact.
