Delete Device Data

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. [1]

Stored data could include a variety of file formats, such as Office files, databases, stored emails, and custom file formats. 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.

Mitigations

ID Mitigation Description
M1005 Application Vetting

Application vetting services could be extra scrutinous of applications that request device administrator permissions.

M1007 Caution with Device Administrator Access

There are very limited circumstances under which device administrator access should be granted.

M1011 User Guidance

Users should be trained on what device administrator permission request prompts look like, and how to avoid granting permissions on phishing popups.

Detection

Mobile security products can detect which applications can request device administrator permissions. Users can view applications with administrator access through the device settings, and may also notice if user data is inexplicably missing.
