Researchers in the U.S. and Canada have managed to track a cyber-espionage ring based in China. The group, known as Shadow, apparently targeted computers in several countries including systems belonging to other governments including those of India and Pakistan. The ring was traced back to Chengdu, in China's Sichuan province. The individuals or groups behind the ring used social media and blogs to control the computers which have previously been compromised with malware. While other countries were affected, the primary target seemed to be the Indian government and military.
