Some financial instutitions are now offering so-called “cardless ATM” transactions that allow customers to withdraw cash using nothing more than their mobile phones. But as the following story illustrates, this new technology also creates an avenue for thieves to quickly and quietly convert stolen customer bank account usernames and passwords into cold hard cash. Worse still, fraudulent cardless ATM withdrawals may prove more difficult for customers to dispute because they place the victim at the scene of the crime.
A Christmas Eve cyberattack against the Web site of a regional California financial institution helped to distract bank officials from an online account takeover against one of its clients, netting thieves more than $900,000.
The $180,000 robbery took the building security and maintenance system installer Primary Systems Inc. by complete surprise. More than two-dozen people helped to steal funds from the company’s coffers in an overnight heist in May 2012, but none of the perpetrators were ever caught on video. Rather, a single virus-laden email that an employee clicked on let the attackers open a digital backdoor, exposing security weaknesses that unfortunately persist between many banks and their corporate customers.
Last week, security firm RSA detailed a new cybecriminal project aimed at recruiting 100 botmasters to help launch a series of lucrative online heists targeting 30 U.S. banks. RSA’s advisory focused primarily on helping financial institutions prepare for an onslaught of more sophisticated e-banking attacks, and has already received plenty of media attention. I’m weighing in on the topic because their analysis seemed to merely scratch the surface of a larger enterprise that speaks volumes about why online attacks are becoming bolder and more brash toward Western targets.
