How Do Banking Trojans Bypass Two-Factor Authentication?

Are you confident that the one-time SMS secret key dependably safeguards your versatile bank? Consider it! In this article, we make sense of how banking Trojans sidestep two-factor verification. Banking foundations broadly utilize two-factor validation through SMS. Clearly, this action works better compared to an essential secret key, yet it is sensible.

Security specialists found how it very well may have been avoided a decade prior when this safety effort was acquiring prominence. The equivalent goes for malware makers. That is the reason engineers of banking Trojans effectively break one-time SMS passwords. This is the carefully guarded secret:

  • A client opens an authority banking application on his cell phone;
  • A trojan recognizes which application is being utilized and overlays a phony duplicate on its point of interaction (the fake screen is equivalent to the genuine one);
  • The casualty enters the login certifications into the phony application;
  • Then the lawbreakers demand a monetary exchange from their record;
  • The Trojan sends the client’s certifications to lawbreakers, who use them to sign in to the client’s genuine banking application;
  • The casualty’s telephone gets an SMS with the one-time secret phrase;
  • The Trojan concentrates the secret phrase from the SMS and sends it to the cybercriminals;
  • It additionally conceals the SMS from the client. This is on the grounds that the casualty only knows about the tasks underway once he checks his financial balance and exchanges.
  • Crooks utilizes the caught secret word to affirm the exchange and get the casualty’s cash.

It is not at all an exaggeration to say that every modern banking Trojan knows how to bypass two-factor authentication systems with SMS. In fact, malware creators have no other choice: since all banks use this security measure, Trojans have to be adapted. Many illegal apps can do this—more than you might imagine. In the last two months alone, our experts have published three detailed reports dedicated to three different malware families. Each is more fearsome than the other!

  • Asacub: A SPY application that developed into a Trojan and figured out how to take cash from versatile banks
  • Acecard is a mighty Trojan capable of overlaying the interfaces of almost 30 different banking apps. By the way, mobile malware is now dominating this trend. In the beginning, Trojans targeted an app of a particular bank or payment service, but now they manage to spoof many apps at the same time.
  • Banloader is a cross-platform Trojan of Brazilian origin, capable of entering PCs and mobile devices simultaneously.

As you can see, two-factor authentication cannot protect you from banking Trojans. It failed for many years, and now the situation is not improving. That’s why you need additional security measures. The basic rule, helpful but not 100%, is to install apps only from official stores. The point is that there have been enough cases where Trojans have succeeded with the Play Store or even the App Store.

This is why the most reliable solution is to install a good antivirus on your mobile phone. The malware also integrates features that allow it to capture screenshots, steal personal information and initiate a self-destruct procedure. The highlight, however, is its ability to intercept SMS and steal codes from applications for generating one-time passwords used as a second authentication factor. The technique used is to exploit Android accessibility services, which are now the favorite tool for hackers to guarantee the usability of their malware.
