AndroRAT is disguised as an Android utility application called TrashCleaner, downloaded from a malicious URL. When opened, TrashCleaner prompts the user to download a Chinese-language calculator application, before hiding its icon in the UI. Once hidden it will initiate command and control communications.

  • Connected network names and passwords.
  • Mobile network cell and GPS locations.
  • Incoming and outgoing call logs.
  • Sent and received SMS messages.
  • Contacts lists.
  • Installed application and file names.
  • Calendar events and mail items.

Alongside this, AndroRAT is able to perform the following actions:

  • Record audio and calls.
  • Take photos using the device cameras.
  • Monitor incoming and outgoing SMS messages.
  • Send and delete SMS messages.
  • Upload and download files.

  • Execute shell commands.
