Chinese hacking teams have been blamed by Western intelligence agencies and cybersecurity groups for digital intrusion campaigns across the world, targeting everything from government and military organisations to corporations and media groups

Cybersecurity firms believe many of those groups are backed by China's government. U.S.-based Mandiant has said some Chinese hacking groups are operated by units of China's army.
