Security firms McAfee and Guardian Analytics have published a joint fraud report, dubbed Operation High Roller, on new methods of siphoning money from banking systems. Using a series of highly sophisticated cyber attacks to target high balance accounts, criminals have been able to successfully bypass physical "chip and pin" authentication and use server-based fraudulent transactions to steal money from a number of accounts in Europe. The attacks originated in Italy, using SpyEye and Zeus malware to transfer funds into fraudulent accounts.
The majority of attacks appear to have taken place across European banking systems, but McAfee warns that it has found evidence of attacks at Latin American and North American financial institutions too. The company is warning that 60 servers have been processing thousands of attempted thefts from high-value accounts over a period of months, resulting in attempts to steal at least €60 million (US$78 million). McAfee says that if all the attempted fraud attacks were successful then the total attempted fraud could be as high as €2 billion ($2.49 billion).
