System Information Discovery

An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, and architecture.

On Android, much of this information is programmatically accessible to applications through the android.os.Build class.[1]

On iOS, techniques exist for applications to programmatically access this information.[2]

ID Mitigation Description
M1005 Application Vetting

App vetting procedures can search for apps that use the android.os.Build class, but these procedures could potentially be evaded and are likely not practical in this case, as many apps are likely to use this functionality as part of their legitimate behavior.
