  • 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.
