Avoid The Risks Of Social Networking
Social networking sites such as Twitter, LinkedIn, FaceBook, and MySpace have become wildly popular for both personal and business use. But whether you use Windows or Mac, there are some risks. Social networking sites do not guarantee your safety, so it’s up to you to protect yourself.
Fake profiles are often used to deliver viruses and scareware. They lure you in with a realistic-looking personal profile in order to get you to click links to malicious sites. Don’t accept “friend” invitations unless you actually know the person or can verify who he or she is, and restrict your profile so that only your friends can see it.
Scammers also break into social networking accounts to steal personal information and send spam to your contacts. Use strong passwords (see my PDF tip sheet), encourage your friends to do the same, and check your security protections to make sure they are current and working properly.
Similarly, phishing scams may use information from your social networking profile to send you spam emails. By targeting you with specific information, such emails are harder to detect. Again, use good security practices and practice your anti-phishing skills with tests like this one from SonicWall.
Fake advertising, or malvertizing, uses realistic-looking ads to get you to click on sites that will infect you with viruses. These ads are often served by third parties and not necessarily by the social networking site. We’ve seen this before where news sites are infected with bad ads. Be wary of any advertisement offered to you, even if it’s on a legitimate site.
Real-life criminals are also using social networking sites to their advantage. Burglars are using them to find out more about who you are and where you live, and even when you’ll be on vacation. Be cautious about sharing pictures or information about yourself and your family online.
Another way to avoid problems is to expand short addresses before clicking. Twitter users often abbreviate using services like tinyurl.com or bit.ly, but such abbreviations can hide malicious sites. Use a program like ExpandMyURL or UnTiny to expand those abbreviations, plus McAfee SiteAdvisor or LinkExtend for Firefox to check out the expanded sites before you click on them.
