Attackers turned defenders

China's largest cybersecurity service company says it will combat online threats by attracting the best Internet talent, including former hackers.

People who have the ability to launch cyber attacks are also good at defending against such threats, said Qi Xiangdong, president of Qihoo 360.

"When security threats, including viruses or Trojan horses, appear in cyberspace, they can brainstorm to find ways to beat them," he says.
