Shows a working accessibility-service malware that uses accessibility node tree traversal, overlays, orientation sensors and wake locks to read screens, perform gestures and steal sessions; a demo converts a $1 transfer into $600 without user awareness. Credential-stuffing uses combo lists (Telegram) and a C2 that pushes scripts so infected apps call the app’s real APIs, bypassing MTLS/WAF; tests hit 5–7 logins/sec per device and the ecosystem scales to hundreds of thousands / half a million devices. Android 12/13 mitigations and Abdom-style detection are discussed.
