  • Family: Cerberus

    An Android banker that is being rented to actors beginning in 2019.

  • Accessibility-driven UI automation to self-grant permissions 2 IoCs

    Locates nodes in the Settings or package-installer user interface by text or view identifier and dispatches synthetic clicks. This lets the application approve its own permission dialogs, complete side-loading, and intercept attempts to reach the uninstall screen without any real user consent.

  • 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.

  • Removes its main activity from the application launcher 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 the phone number (MSISDN for GSM devices) 1 TTPs
  • Performs UI accessibility actions on behalf of the user 1 TTPs 4 IoCs

    Application may abuse the accessibility service to prevent their removal.

  • Queries the mobile country code (MCC) 1 TTPs 1 IoCs
  • Requests disabling of battery optimizations (often used to enable hiding in the background). 1 TTPs 1 IoCs
  • Listens for changes in the sensor environment (might be used to detect emulation) 1 TTPs 1 IoCs
  • Registers a broadcast receiver at runtime (usually for listening for system events) 1 TTPs 1 IoCs
  • Checks CPU information 2 TTPs 1 IoCs
  • Checks memory information 2 TTPs 1 IoCs
