'Ruthless' Trojan horse steals 500k bank, credit card log-ons

A sophisticated cybercrime group that has maintained an especially devious Trojan horse for nearly three years has stolen the log-ons to more than 300,000 online bank accounts and almost as many credit cards during that time, a security company said today.
Researchers at RSA Security Inc.'s FraudAction Research Labs tracked the Sinowal Trojan horse, also known as Mebroot and Torpig, to a drop server that contained the stolen credentials, said Sean Brady, the product marketing manager at RSA's ID and access assurance group.
"The sheer enormity of this makes this unique," said Brady. "And the scale is very unusual." All told, the gang behind Sinowal managed to obtain access to nearly half a million bank accounts and credit cards, a volume RSA dubbed "ruthless" and "extraordinary."
"And the fact that the Trojan was managed by one group through its history and maintained for nearly three years is also very unusual," Brady said. RSA uncovered records that showed the Trojan horse had been in active operation since at least February 2006. "In malware life cycles, that's ancient, and to keep it up required a high degree of resources and effort."
