Hackers Increasingly Using Twitter For Botnets

"Spammers aren't the only ones who have figured out that social networks like Twitter and Facebook are good for business. Sophisticated hackers conducting targeted attacks are also using the networks as a tool to manage malware installations on victims' networks. Mandiant's latest "M-Trends" report, released on Thursday, says that the company has observed an increasing number of so-called "Advanced Persistent Threats" that are hijacking legitimate social networks and Web based services, including Facebook, Google Chat and MSN as command and control networks for malware installations. The revelation is part of a larger trend that saw sophisticated attacks on commercial entities outstrip attacks on the networks of government agencies and defense industry players, Mandiant reported."
