Beware of another Facebook scam !

US: Have you been hit like millions of Facebook users by a new phishing scam that can result in crashing your computers or mobile phones and steal your passwords?

If not, beware, do not open the files ending with ".at" or ".be".

The phishing scam is being run through the spam messages which steals the sensitive information of the Facebook users.

In the attack, the messages are circulated with a subject line of "Hello" and a prompt to check out "areps.at" or other URLs ending in ".at".

The mails with the subject line "Look at This" and links like -- goldbase.be, greenbuddy.be, silvertag.be, picoband.be -- leads to some malicious Web sites, which if visited, could secretly download malware onto computers through a "drive-by download" application.

"Whoever is behind the scam has been steadily amassing a large number of e-mail addresses and passwords over the past few weeks," the blog says.

Though, Facebook spokesman Barry Schnitt said: "The impact of this attack or the previous ones are not widespread and only impacted a tiny fraction of a per cent of users.

"We've been updating our monitoring systems with information gleaned from the previous attacks so that each new attack is detected more quickly," he said.

The site has blocked links to the new phishing sites from being shared on Facebook and has added them to the block lists of the major browsers.
