Notifications purportedly sent by the US Securities and Exchange Commission have been hitting inboxes and trying to trick users into following a malicious link, warns GFI.

You can have access to the complaint details in U.S. Securities and Exchange Commission Tips, Complaints, and Referrals portal under the following link:

Those unfortunate enough to open it will be redirected through a number of sites and will finally end at one that hosts the Blackhole exploit kit, which is able to take advantage of a number of Adobe Reader, Acrobat and Flash vulnerabilities, as well as some on Java and Windows Media Player.
If the kit manages to exploit one of those, the user is finally taken to a website where he can download the about.exe file.
Sadly, this is not a document containing details of the complaint, but a variant of the Zeus/Zbot information-stealing Trojan that is currently detected only by a dozen of the AV solutions employed by VirusTotal.
