- Family: Alienbot
Alienbot is a fork of Cerberus banker first seen in January 2020.
- Family: Cerberus
An Android banker that is being rented to actors beginning in 2019.
- Cerberus payload 2 IoCs
- Contact harvesting with SMS self-propagation 2 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.
- Covert microphone or camera capture with exfiltration 2 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.
- 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.
- Notification listener abuse for OTP and message theft 2 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
- Removes its main activity from the application launcher 1 TTPs 1 IoCs
- Checks Android system properties for emulator presence. 1 TTPs 1 IoCs
- Loads dropped Dex/Jar 1 TTPs 3 IoCs
Runs executable file dropped to the device during analysis.
- Makes use of the framework's Accessibility service 4 TTPs 2 IoCs
Retrieves information displayed on the phone screen using AccessibilityService.
- Queries account information for other applications stored on the device 1 TTPs 1 IoCs
Application may abuse the framework's APIs to collect account information stored on the device.
- Queries the phone number (MSISDN for GSM devices) 1 TTPs
- Performs UI accessibility actions on behalf of the user 1 TTPs 2 IoCs
Application may abuse the accessibility service to prevent their removal.
- Queries the mobile country code (MCC) 1 TTPs 1 IoCs
- Reads information about phone network operator. 1 TTPs
- Requests disabling of battery optimizations (often used to enable hiding in the background). 1 TTPs 1 IoCs
- Registers a broadcast receiver at runtime (usually for listening for system events) 1 TTPs 1 IoCs
- Schedules tasks to execute at a specified time 1 TTPs 1 IoCs
Application may abuse the framework's APIs to perform task scheduling for initial or recurring execution of malicious code.
- Checks CPU information 2 TTPs 1 IoCs
- Checks memory information 2 TTPs 1 IoCs
