Characteristics of MasterFred Malware

“By utilizing the Application Accessibility toolkit installed on Android by default, the attacker can use the application to implement the Overlay attack to trick the user into entering credit card information for fake account breaches on both Netflix and Twitter. Some important things of note to this malware are that the Assets folder within the application is where the HTML overlays for common applications are stored along with fake bank login overlays in multiple languages.”

according to Avast Threat Labs.

  • The malware is targeting Android devices 
  • Applications through which the malware triggers bundle the HTML overlay
  • False login forms are shown and used to perform financial data theft 
  • To steal data MasterFred uses Tor2Web proxy 

How does MasterFred Malware Work?

To target, Android devices threat actors implemented MasterFred in fake Android apps that look genuine enough and match Twitter, Instagram, and Netflix.  Once downloaded, the user is asked to log in (same as asked in real services).

Afterward, they are asked to enter credit card details, which when entered goes to the hacker and they take advantage of it.

This is not a new practice. Several other threats also used the Accessibility services to navigate the Android UI and install payloads. However, MasterFred is more advanced than the older version as it uses the dark web gateway (aka Tor2Web proxy) to send the stolen information.
