T1424 Process Discovery

Adversaries may attempt to get information about running processes on a device. Information obtained could be used to gain an understanding of common software/applications running on devices within a network. Adversaries may use the information from Process Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.

Recent Android security enhancements have made it more difficult to obtain a list of running processes. On Android 7 and later, there is no way for an application to obtain the process list without abusing elevated privileges. This is due to the Android kernel utilizing the hidepid mount feature. Prior to Android 7, applications could utilize the ps command or examine the /proc directory on the device.1

In iOS, applications have previously been able to use the sysctl command to obtain a list of running processes. This functionality has been removed in later iOS versions.
