Match Legitimate Name or Location
Where this stands
No Sigma rule can address this — the telemetry MITRE names has no Sigma logsource behind it.
Sigma has no logsource taxonomy for mobile platforms. MITRE's telemetry here is mobile EDR and device APIs, which no Sigma rule can address.
What the technique is
Adversaries may match or approximate the name or location of legitimate files or resources when naming/placing them. This is done for the sake of evading defenses and observation. This may be done by giving artifacts the name and icon of a legitimate, trusted application (i.e., Settings), or using a package name that matches legitimate, trusted applications (i.e., com.google.android.gm). Adversaries may also use the same icon of the file or application they are trying to mimic.

Unexpected behavior from an application could be an indicator of masquerading. Application vetting services may potentially determine if an application contains suspicious code and/or metadata.
