Trailrunner7 writes: U.S. and international prosecutors have taken down a criminal ring that they allege was responsible for an ATM scam last year that stole about $9 million from RBS WorldPay. The criminals were able to evade the company's encryption system used on payroll debit cards and withdraw money from ATMs in 280 cities around the world. A federal grand jury in Atlanta has indicted eight men in connection with the scheme, including five Estonians, one Russian, one Moldovan and one unidentified man. Prosecutors allege that the men "used sophisticated hacking techniques" to defeat the company's encryption system. The scam, which hit RBS WorldPay last November, involved an elaborate plan in which the attackers first bypassed the encryption on the debit cards, which RBS WorldPay issues to customers for employee payroll purposes. They then raised the limits on the accounts attached to the cards.
