    Retrieves information displayed on the phone screen using AccessibilityService.

  • Prevents application removal 1 TTPs 1 IoCs

    Application may abuse the framework's APIs to prevent removal.

  • Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps) 1 TTPs
  • Removes its main activity from the application launcher 1 TTPs 1 IoCs
  • Requests accessing notifications (often used to intercept notifications before users become aware). 1 TTPs 1 IoCs
  • Loads dropped Dex/Jar 1 TTPs 2 IoCs

    Runs executable file dropped to the device during analysis.

  • Makes use of the framework's foreground persistence service 1 TTPs 1 IoCs
