Guns and masks are no longer necessary to rob the banks or ATMs. Rather, cyber thieves can lounge in their pajamas and hack away. As set forth in a recent indictment, a gang of international cyberthieves allegedly stole $45 million between October 2012 and April 2013. According to the indictment, the alleged gang carried out two major attacks. In the first attack, the gang allegedly targeted a credit card processor that handled prepaid MasterCard debit cards issued by the National Bank of Ras Al-Khaimah, a United Arab Emirates bank also known as Rakbank. After penetrating the processor's computer network, the hackers manipulated the balances and withdrawal limits on prepaid debit card accounts. In less than three hours, the thieves allegedly conducted 750 fraudulent transactions that withdrew nearly $400,000 from approximately 140 New York City ATM locations. The alleged second attack occurred between Feb. 19th and Feb. 20th. In this attack, the hackers allegedly compromised computers of the processor of prepaid debit cards for the Bank of Muscat, located in Oman. In approximately 10 hours, the gang members, in 24 countries, conducted approximately 36,000 ATM transactions worldwide, withdrawing an estimated $40 million, according to the indictment. Authorities in more than a dozen countries are working on the investigation.
