Bogus Microsoft security bulletin (HIDDEN TROJAN)

Experts are warning of a bogus Microsoft security bulletin that contains malware designed to take control of the user’s PC.

The emails contain the header ‘Microsoft Security Bulletin
MS07-0065′ and come with Microsoft logos and a layout very similar to
the Microsoft web page.

Recipients are told that a zero-day flaw in Outlook has already been
exploited to infect over 100,000 machines, and the email contains a
link to the ‘patch’ for the problem.

“Security bulletins from Microsoft describing vulnerabilities in its
software are a common occurrence, so it comes as no surprise to see
hackers adopting this kind of disguise in their attempt to infect
Windows PCs,” said Graham Cluley, senior technology consultant at Sophos.

“The irony is that, as awareness of computer security issues and the
need for patching against vulnerabilities have risen, social
engineering tricks which pose as critical software fixes are likely to
succeed in conning the public.”

The link in fact downloads the Behav-112 Trojan, which allows the
computer to be operated remotely to send spam or take part in
distributed denial-of-service attacks.

The emails have been widely spammed out over the past few days. (Click here…)
