  • Hook

    Hook is an Android malware that is based on Ermac with RAT capabilities.

  • 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 3 IoCs

    Retrieves information displayed on the phone screen using AccessibilityService.

  • Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps) 1 TTPs
  • Queries information about running processes on the device 1 TTPs 1 IoCs

    Application may abuse the framework's APIs to collect information about running processes on the device.

  • Queries the phone number (MSISDN for GSM devices) 1 TTPs
  • Acquires the wake lock 1 IoCs
  • Makes use of the framework's foreground persistence service 1 TTPs 1 IoCs

    Application may abuse the framework's foreground service to continue running in the foreground.

  • Performs UI accessibility actions on behalf of the user 1 TTPs 9 IoCs

    Application may abuse the accessibility service to prevent their removal.

  • Queries information about the current Wi-Fi connection 1 TTPs 1 IoCs

    Application may abuse the framework's APIs to collect information about the current Wi-Fi connection.

  • Reads information about phone network operator. 1 TTPs
  • Requests accessing notifications (often used to intercept notifications before users become aware). 1 TTPs 1 IoCs
  • 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.
