SMS Messages
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 utilize standard operating system APIs to gather SMS messages. On Android, this can be accomplished using the SMS Content Provider. iOS provides no standard API to access SMS messages. If the device has been jailbroken or rooted, an adversary may be able to access SMS Messages without the user’s knowledge or approval.

OLD: Application vetting services could look for android.permission.READ_SMS in an Android application’s manifest. Most applications do not need access to SMS messages, so extra scrutiny could be applied to those that request it. On Android, the user can manage which applications have permission to access SMS messages through the device settings screen, revoking the permission if necessary. NEW: A defender observes an Android application requesting for android.permission. READ_SMS and/or android.permission. RECEIVE_SMS, which may also be listed in the application's manifest file.
