Bank of America spam spreading Waledac worm
Wednesday, June 3, 2009
Web security researchers have spotted phishing spam purporting to be from Bank of America that could infect recipients with the Waledac worm.
The spam contains a malicious link to a website that spoofs a Bank of America digital certificate update. Users are asked to fill in a web form with their account information and hit a submit button that is actually an executable file that downloads the worm, security researchers said.
Experts said the spam originates from the Pushdo botnet, which has been active in previous phishing attacks, according to SCmagazineUS.com. This time, the phishing attack seeks to steal login information at the same time as it infects the user with Waledac. Once infected with the worm, a user's PC can be taken over as part of the Waledac botnet, which may also be used to steal private data from users' machines. It spreads to other machines by collecting email addresses stored on the compromised machine and sending out spam emails.
Bank of America told SCMagazineUS.com that it was aware of the scam and is continuing to research the issue to protect its customers.
