Security company F-Secure was the target of a bogus mail campaign designed to spread malware by luring recipients into opening a bogus screen shot.

Thousands of infected e-mails were sent out on Wednesday, purporting to be from a non-existent F-Secure employee. According to the company, addresses used included press@f-secure.com, info@f-secure.com and editor@f-secure.com. All the mails indicated they were from "David Adams, Dept. Research, F-Secure Development."

In the mail, the fictitious Mr. Adams claimed that he'd found browser incompatibilities while viewing the recipient's site using the open source Mozilla browser.

"I have enclosed a screen capture of the problem so your team can get it fixed if you deem it an issue," read the message.

The attached file, however, contained a variant of the Breplibot worm.

The company said it has taken steps to notify users of the attack.

A sample of the message follows.

using the Mozilla browser.
As more people are turning to alternative browsers now it may be
of help for you to know this. I have enclosed a screen capture of
the problem so your team can get it fixed if you deem it an

The company reported that it has no indication of who originated the message.
