Following swiftly on the heels of the social networking giant Facebook is Twitter, and its popularity has not gone unnoticed by hackers. The micro-blogging site is a rich playing field for malicious attacks, which usually come in the form of infected URLs that download malware onto users' computers. Meanwhile, hackers routinely exploit the trust users have by spoofing users' profiles and then tricking contacts into opening an infected link via some social engineering scheme.
Last year, a Twitter worm made its rounds, compromising thousands of users' accounts by enticing users to download rogue antivirus software created to steal passwords and take control of users' computers. In addition, the site has repeatedly been subject to a spate of phishing attacks that redirected users to a fake login page and then tricked them into submitting their personal information and login credentials.
