In February 2009, spam levels on the popular social networking website Twitter hovered between 5.5 and 6 percent of the sites posts. Thanks to concerted efforts to remove known spammers, decrease phishing attacks and scan all posted links for potentially malicious software, Twitter recently announced on its company blog that spam levels on the site are now down to 2 percent of all the website's posts.

The website actively encourages users to report any instance of spam and frequently change and vary their passwords to curtail the effects of phishing attacks.

Even with its advice, Twitter recently experienced another wave of phishing attacks, according to TheNewNewInternet.com. As is the case with most phishing attacks, direct messages sent from a user claimed to have a humorous video or photo of the recipient. When the link is clicked, the user is redirected to a fake Twitter page that ask for login information.

Phishing attacks on social networking sites are especially dangerous for businesses. Teneros, a software company, recently announced the development of a program that helps businesses track the social networking use of their employees.ADNFCR-2553-ID-19697911-ADNFCR
