The delegates of the Virus Bulletin conference in Vancouver may be having a restful weekend after the closing address on Friday afternoon, but that doesn't mean their cybercriminal counterparts have also been taking it easy.
Take for example, this survey scam which is spreading rapidly across Facebook - posing as 4000 free points for the Xbox 360 games system.
Free 4000 Xbox Live Points

You should remember, of course, that if something looks too good to be true, it probably is.
In this case, if you click on the link you are taken to a webpage hosted on blogpost.com which asks you to follow some "easy steps" to get your 4000 Xbox Live Points.
Firstly, they ask you to "Like" their page. Then they insist that you share an advert with your online Facebook friends about the free Xbox Live Points they claim they are handing out.
Worryingly, many people seem only too keen to do this.
Finally, they say you will need to take a survey in order to receive your points.
This is where the scammers make their money. Every person who completes a survey earns a slither of commission for the charlatans who are pretending to offer you free Xbox Live Points, and you're helping them generate even more income by liking their page and sharing it with your Facebook friends.
The success and wide variety of such survey scams spreading across Facebook and other systems is one of the biggest security stories of 2010. You need to have your wits about you to avoid falling into the scammers' hands - always think carefully before you "like" or "share" a suspicious link on Facebook.
