But now, Trusteer, a security company has prepared a report which states that Zeus is aimed at customers of 15 unnamed US banks. Not just the credit card information, it even captures social security and card numbers, and PIN or card verification codes. An established user would not, presumably, be vulnerable unless they entered the password they created when they signed up originally. Sadly, Anti malware detection of Zeus has a poor track record. Trusteer found that among Zeus infected machines 55% had up-to-date Antivirus protection installed. The population of machines infected with Zeus is enormous — one in every 100 computers according to Trusteer research.
