Bugbear.B: The B is for bank
Admittedly I don't know that for certain, but it certainly seems plausible in light of this article
at CNN.com. Virus experts looking at the code for Bugbear.B discovered that it had the domain names of as many as 1,300 financial institutions in its code. Apparently the virus was programmed to look at the e-mail address on a machine to see if it contained one of the domain names. If it did, the virus attempted to grab passwords and other information and forward it to a list of e-mail addresses.
Needless to say, if the FBI was interested in finding the author of this virus before, they're probably even more interested now. According to the article, this may be the first time that a virus has targeted a specific economic sector. I wonder if it's also the first virus written for the purpose of financial gain? Hey, it's more practical than writing one as an homage to a stripper, right?
