"Still going strong since February 2006, the 'Sinowal' Master Boot Record infector (also called 'Torpig' and 'Mebroot' by various anti-virus companies) has compromised more than half a million financial accounts. An HTML injection engine adds fields to login pages to compromise credentials. Injection is triggered by the Web addresses — more than 2,700 bank and e-commerce sites are hard-coded into the malware. 'RSA investigators found more than 270,000 online banking account credentials, as well as roughly 240,000 credit and debit account numbers and associated personal information on Web servers the Sinowal authors were using to set up their attacks.' The majority of anti-virus and anti-malware scanners do not detect this threat."
