The command and control centres (C&C) for more than half of the world’s botnets are in the US, not China, says security firm CheckPoint.

A recent report by US cyber security firm Mandiant said a Chinese military base in Shanghai is one of the world's "most prolific cyber espionage groups," yet only 4% of botnets are controlled from China.

Conversely, 58% of botnets that have hijacked computers in 63% of organisations worldwide have their C&C centres in the US, according to latest enterprise security report from CheckPoint. The report highlights that 53% of those hijacked computers were infected with new malware at least once a day as a result of existing infections on their networks.
