In the latest indication that cyber-espionage campaigns have become a major threat to the wealth and security of nations, a foreign entity has been exposed for trying to steal secrets from more than 70 organizations – including two Canadian government departments and the World Anti-Doping Agency in Montreal. The snooping – described as one of the largest such series of attacks ever documented – was carried out over the past five years by a group that has yet to be identified. Suspicions, however, are again centring on China, given that the list of targets includes the United Nations, governments in the West and Southeast Asia, military-defence contractors, and international sports bodies that were hit around the time of the 2008 Beijing Olympics.
