Detects instances where an Android application, installed from a non-standard source (sideloaded via ADB or unknown sources), requests the BIND_ACCESSIBILITY_SERVICE permission for a service named 'SystemHelper'. This behavior is characteristic of mobile malware like Rathat that leverages accessibility services to gain unauthorized control over user credentials and bank accounts.

Detects Linux processes masquerading as 'php-fpm' or 'postgres' that match known SHA-256 hashes associated with the RedTail malware family. The rule identifies processes attempting to hide their identity using techniques similar to prctl(PR_SET_NAME) to rename themselves while running malicious code.

This rule monitors for indicators of compromise (IOCs) associated with the Rapuncel/Cruciferra 'Bring Your Own Vulnerable Driver' (BYOVD) malware-as-a-service (MaaS) campaign. It detects malicious file hashes (associated with dropped binaries or drivers), connections to known malicious command-and-control (C2) IP addresses, and network requests to domains used by the infrastructure.
