Consumers and businesses in Great Britain have lost more than $1 million so far this summer from a Trojan that is infecting their computers, prompting them to log into their bank accounts, and then is surreptitiously transferring money to scammers in other countries, security researchers said on Tuesday.
About 3,000 bank accounts were found to be compromised at one financial institution, which was not identified, according to a white paper released by M86 Security.

The multilevel scheme uses a combination of a new version of the Zeus keylogger and password stealer Trojan, which targets Windows-based computers and runs on major browsers, and exploit toolkits to get around anti-fraud systems used at bank Web sites, the report found.

Bank sites that offer two-factor authentication, such as one-time passcodes and ID tokens, are ineffective because the malware has taken over the browser after the victim has logged into the banking site, Bradley Anstis, vice president of technology strategy at M86 Security, told CNET.
