This is no creation of a prankster. According to Klein, the sophistication of its creators is revealed by the fact that there's a Web portal ready to sell the data that the malware
has harvested. What apparently makes this malware cunning is that it can forward data in real-time to scammers; the MitB attack captured data that needed to be filtered.
According to Trusteer, the malware at the moment isn't on many Web sites. If so, they only have a short period of time to mount a defence.
