Hacking attack in Canada bears signs of Chinese army unit: expert

OTTAWA/TORONTO: The recent hacking attempt on a sensitive Canadian government computer network is similar to attacks mounted by an elite unit of the Chinese army based in Shanghai, according to a cybersecurity expert. 

Canada said on Tuesday "a highly sophisticated Chinese state-sponsored actor" had broken into the National Research Council, a leading research body that works with major companies such as aircraft and train maker Bombardier Inc. Beijing on Thursday accused Canada of making irresponsible accusations that lacked credible evidence.
