Multidisciplinary Bank Attacks

Online Web banking applications have evolved considerably in the last decade; however the financial losses by their customers due to account compromise appear to be increasing. While the banks have invested in their application security, organized criminal teams appear to have been investing more - and are coming up with new vectors that emphasize attacks that take place on the customer’s host.

Attacking a bank and its customers is a multidisciplinary activity engaged by well organized and well funded international criminal teams. Advances in authentication processes – whether they be multi-factor, temporal-based combinations of one-time pads, or other backend validation processes – have proved ineffective since the attackers have focused upon the financial transaction itself. The combination of drive-by-download infection vectors, custom “Swiss-army knife” malware, banking application logic flaws and end-user complexity are all now leveraged to conduct a successful attack.

Security professionals need to provide a multidisciplinary understanding of the threat to their clients. The use of malware and social engineering cannot be divorced from Web application vulnerabilities any longer.

This session examines how malware is successfully leveraged within organized online banking attacks to bypass even the most sophisticated application logic. I will explain how current state-of-the-art man-in-the-browser technologies have overcome advanced authentication techniques and transaction validation processes. We will discuss how banking application complexity and ill thought-out logic changes can (and are) leveraged by criminals to socially engineer the customer in to falling for their criminal deception. And, finally, I will explain how even out-of-band multi-factor authentication systems such as SMS-based tokens are likely to be bypassed in the future.

What does Web application security look like if you cannot trust anything that goes to, or comes from, your customers host?
