Social networking security: Protect yourself

As social networking tools change the way we communicate, spammers have begun turning their attention to services such as Facebook and MySpace, tricking users into installing viruses, launching fraudulent websites and deploying malware throughout their computers and networks, accoring to a a new report by MessageLabs.

While spamming via e-mail services remains prevalent, "spammers see social networks as the new horizon," says Matt Sergeant, senior anti-spam technologist at MessageLabs. Spammers have managed to set up phony social networking accounts, according to MessageLabs, by breaking the protections set in place by a safeguard known as CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart), the letters you normally have to type in when you register for a website that says "Are you a human?"

Luckily, if you're wading in the social networking pool, you can revisit some core security principles in order to protect yourself from spammers and other characters on Facebook who can ruin your computer or identity, Sergeant says.

1. Re-do your password: It's probably not strong enough

Some cyber criminals have become remarkably good at obtaining social networking passwords through phishing schemes. Sergeant cites the case of a spammer in Canada who lured Facebook users into offering up their personal information to sign up for products offered by a fake company selling "male enhancement drugs."

In a lawsuit, which Facebook won for an amount just shy of $900 million, the social network alleged that the spammer sent out four million spam messages from accounts in which he had obtained the passwords.

Sergeant says not only should users be wary of phishing schemes, but also of the fact that research indicates spammers are able to guess passwords. He suggests beefing up your password with unpredictable letters, phrases and numbers. At CIO, we recommend checking out this helpful password how-to from our sister site, csoonline.com.
