China cyber-attacks are increasing, western analysts warn

US and UK governments announced sanctions against Chinese firms linked to hacking group

Cyber-attacks linked to Chinese intelligence agencies are increasing in capability and frequency as they seek to test foreign government responses, analysts have warned in the wake of revelations about a mass hacking of UK data.

On Tuesday, the UK and US governments accused hacking group, Advanced Persistent Threat 31 (APT 31), backed by China’s government spy agency, of conducting a years-long cyber-attack campaign, targeting politicians, national security officials, journalists and businesses. The UK said the hackers had potentially gained access to information on tens of millions of UK voters held by the Electoral Commission, as well as for cyber-espionage targeting lawmakers who have been outspoken about threats from China.
