Cybercriminals have already begun shifting their focus from websites to file-sharing networks when it comes to dispensing malware, and will continue with this trend throughout 2010. Security researchers at Kaspersky Labs predict that malicious applications, such as fake antivirus programs, will be on the decline next year as attacks over P2P go up, while more criminals look to target victims via mobile platforms.

In its 2010 Cyberthreat Forecast, Kaspersky Lab said that it expects an increase in mass malware epidemics over P2P networks. 2009 saw a series of mass malware epidemics that were not caused by, but supported by files that were spread over P2P networks. "This method has been used to spread notorious threats such as TDSS and Virut as well as the first backdoor for Mac OS X," the researchers said.
