Android.FakeApp.1426 is a trojan based on RustDesk application code that targets the Android operating system. This trojan provides the ability to remotely control a compromised device.

Operating routine

The trojan, a modified version of the RustDesk application, is detected by Dr.Web anti-virus as Tool.RustDesk.1.origin, with a modified name and icon. It is distributed as an APK file on fraudulent websites, which promise to help users solve their banking problems.

A device is compromised when an APK file is downloaded from a fraudulent website. Attackers posing as bank employees report suspicious activity on the victim's account and offer to install a “security” program, which is Android.FakeApp.1426. They then ask for the “verification code” displayed on the screen, which is the unique identifier of the running program. This allows the scammers to connect to the victim's device. With access to the device, they can successfully bypass all the bank's security checks and withdraw money from the account.

Curing recommendations


  1. If the mobile device is operating normally, download and install Dr.Web for Android Light. Run a full system scan and follow recommendations to neutralize the detected threats.
  2. If the mobile device has been locked by Android.Locker ransomware (the message on the screen tells you that you have broken some law or demands a set ransom amount; or you will see some other announcement that prevents you from using the handheld normally), do the following:
    • Load your smartphone or tablet in the safe mode (depending on the operating system version and specifications of the particular mobile device involved, this procedure can be performed in various ways; seek clarification from the user guide that was shipped with the device, or contact its manufacturer);
    • Once you have activated safe mode, install the Dr.Web для Android Light onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
    • Switch off your device and turn it on as normal.
