A sophisticated cybercrime group that has maintained an especially devious Trojan horse for nearly three years has stolen login credentials of close to 300,000 online bank accounts and almost as many credit cards during that time, according to reports released today by RSA FraudAction Research Lab. The spyware is called Sinowal Trojan, also known as Torpig and Mebroot.

RSA reports that their findings are based on data collected on this Trojan over the course of almost three years—including information regarding its design and its infrastructure. Findings indicate that this may be one of the most pervasive and advanced pieces of crimeware ever created by fraudsters, say RSA experts.

"The sheer enormity of this makes this unique," said Sean Brady, manager of identity protection for RSA. "And the scale is very unusual." Overall, the gang behind Sinowal has managed to gain access to almost half a million bank accounts and credit cards, a volume RSA calls "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.
