  5. 5. More info about the malware • QRecorder: A repackaged app for phone call recording. • Distributed via Google Play, which is a regular channel. • Activated via a remote update in the right moment. Internally, the "Spy.Banker.AIX" malware core was used. • Tailor-made for specific banks. It was able to bypass the additional security measures designed by the banks.
  6. 6. What was the principle of this attack? • The attack was in principle a clever "overlay attack." • The malware was placing an overlay over the regular banking app. It requested sensitive information from the user, pretending a regular mobile app is requesting the info. • After gathering a sufficient amount of the private information, it intercepted SMS OTP sent via bank and took full control over the bank account.
  7. 7. What can banks do? • Invest in App Shielding / RASP technologies to protect their mobile banking apps from overlay attacks and other sophisticated runtime attacks. Learn more → • Be ready and respond fast in the case a similar threat emerges again. • Educate customers, though it would not help in this case, the customers did everything right.

  9. 9. Thank you.
