Twitter, Facebook and MySpace are highly popular social networks. Unfortunately, there are always hackers who try to exploit the success of these networks for financial gain. Such is the case of Twitter, which has become an easy target for hackers to distribute spam.

How can you protect against spam in Twitter?

• Disable the “followback auto” option. This way, you will be able to choose the people you want to follow.
• Do not access all the links you receive. Make sure you know who you are following. 
• Follow the spam profile in Twitter: http://twitter.com/spam. You can find good tips here. For example, according to a recent post,  “If you gave your login and password info to TwitViewer, we strongly suggest you change your password now. Thank you!”
• Install a complete security solution on the computer, preferably with an antivirus, firewall and phishing filter module.

If you follow these tips you will be protected against spam.

What type of spam could I have received?

The most common types are:

• Trending Subjects Spam: This spam searches for popular subjects (e.g. Michael Jackson’s new movie, store discounts, etc.) to publish similar tweets with malicious URLs.
• Tweet spam: This type of message comes from one user following another. Consequently, all the attached followers can see the tweet.
• Direct Message: This direct message comes from a follower. Therefore only the recipient can see it.

Twitter, Facebook, MySpace and other social networking sites are inceasingly being targeted by cyber-criminals drawn to the wealth of personal information supplied by users, experts warn.

Data posted on the sites - name, date of birth, address, job details, email and phone numbers - is a windfall for hackers.

A vicious virus Koobface - “koob” being “book” in reverse - has affected thousands of Facebook and Twitter users since August 2008, said Asier Martinez, our security specialist. “Its spread has been very significant and it has been detected in 4,000 different variants,” he said.

The virus hijacks the accounts of social networking site users and sends messages steering friends to hostile sites containing malware, a malicious software often designed to infiltrate a computer system for illicit purposes.

In one of its variants, Koobface sends the victim a warning that its Flash player is outdated along with an invitation to download a new version, which is in fact the virus.

Remenber that malware can be used to steal bank account data or credit card information once installed on a personal computer.

Facebook has sought to resist attacks by Koobface and similar viruses by blocking links to hostile sites and shutting down accounts from users that show signs of infection, such as sending too many messages.  You also must be very careful with people who ask to join your friends list adding that hackers often sent requests.

Another danger of social networking sites are:

• The popular quizzes.
• Horoscopes and games made available for free to users which can sometimes be used to hide links to hostile sites.
• Birthday greetings as well as messages sent at Christmas and other holidays may also appear to come from friends when in fact they are linked directly to sites that try to convince would-be victims to reveal personal information like passwords or bank numbers.

The number of viruses detected in recent years has exploded while the profile of cyber-criminals has changed. Before it was very savvy teenagers who wanted to show off their computer skills. Now you don’t really need to know much about information technology to be a hacker, all the tools have already been created.

Now, why not sharing with me some of your experiences?
