Bogus ‘Citi Account Alert’ spam leading to Black Hole Exploit Kit

Cyber criminals are currently mass mailing hundreds of thousands of emails impersonating Citi, using two different email templates. When clicked, the links in the malevolent emails lead to the client-side exploits serviced by the latest version of the Black Hole Exploit Kit.

Webroot completed an analysis of the malicious sites being spammed,
