This rule detects a suspicious monetization pattern where a user account experiences a high-risk sign-in event, followed shortly (within 2 hours) by the creation or modification of inbox rules. This pattern is often indicative of account compromise, where an adversary configures mailbox rules (e.g., forwarding or redirection) to facilitate data exfiltration or financial fraud.

Detects a specific concealment behavior attributed to the 'com.corp.mdm' Android implant. The rule monitors for a sequence of events where the application disables its own launcher (main activity) to hide from the app drawer, immediately followed by the initiation of a foreground service that masquerades as a system notification ('Android System' title with 'System service running.' text).

001
Detects malicious Android application installation or launch behavior consistent with the 'Corp MDM' implant. This rule specifically identifies instances where a package named 'com.corp.mdm' is installed or launched and rapidly requests a combination of high-risk permissions including SMS and telephony access (RECEIVE_SMS, READ_SMS, CALL_PHONE) alongside notification permissions, which is characteristic of the implant's initial setup phase.
