Zimperium said RatHat pairs Accessibility abuse with autonomous local ADB (Android Debug Bridge) self-pairing to break out of the Android sandbox, unlock Developer Options, enable Wireless Debugging, and extract the 6-digit ADB pairing code. The malware stages native daemons that execute with shell-level privileges, lets a Go Agent masquerading as liblocal-service.so apply persistence and power management exemptions, and can re-install itself through the local service after uninstall. The operator also uses an FRP reverse-proxy client to establish a persistent reverse tunnel to the C2 server, while the malware can record finger presses on screen with a hardware-level keylogger.
