- Family: Alienbot
Alienbot is a fork of Cerberus banker first seen in January 2020.
- Cerberus payload 1 IoCs
resource yara_rule behavioral2/files/fstream-2.dat family_cerberus - Contact harvesting with SMS self-propagation 1 IoCs
Reads the device contact list and sends messages to the retrieved numbers, the distribution mechanism behind SMS worm campaigns. The victim's own address book becomes the delivery channel, which is why these campaigns spread rapidly within a region.
resource yara_rule behavioral2/files/fstream-2.dat ANDROID_Contacts_SMS_Propagation - Covert microphone or camera capture with exfiltration 1 IoCs
Opens audio or camera capture outside any user-facing recording feature and pairs it with file staging and network transmission. The absence of a foreground recording interface alongside these primitives indicates surveillance rather than a legitimate media function.
resource yara_rule behavioral2/files/fstream-2.dat ANDROID_Surveillance_AudioCamera_Capture - Encrypted or packed staged payload inside Android package 1 IoCs
Extracted asset shows near-random entropy without a recognised container header, indicating an encrypted secondary payload staged for runtime decryption and loading. Correlate with any runtime class-loading detection on the same sample.
resource yara_rule behavioral2/files/fstream-1.dat ANDROID_Encrypted_Staged_Asset - Notification listener abuse for OTP and message theft 1 IoCs
Binds a notification listener service and reads posted notification content, optionally dismissing notifications afterwards to hide them. This harvests one-time passcodes and private messages without ever requesting SMS permissions, which is why it has largely replaced SMS interception in modern ban
