UK government agencies, think tanks, businesses and charities also appear in the leaked i-Soon data.
Other documents hint at successful hacks of public bodies and businesses across Asia and Europe, but it is not yet clear if any were compromised.
The identity of the leaker is unknown.
i-Soon is one of many private companies that provide cyber security services for China’s military, police and security services.
It employs less than 25 staff at its Shanghai headquarters.
There is loads of Chinese stuff on UK networks. I can believe Chinese, with backdoors, is in UK Foreign Office. US do it too. IT might be good, but people quietly bypass them for ease over security.
