Chinese authorities have broken a hacking-tool dissemination ring, according to state media.
Police in the central Hubei province arrested three people suspected of running the Black Hawk Safety Net, state news agency Xinhua reported on Monday.
The Black Hawk Safety Net disseminated hacking tools and Trojans to its members, said Xinhua. The group had collected seven million yuan (£650,000) in membership fees from 12,000 subscribers by the time it was shut down. The group had an additional 170,000 members who had joined for free, said Xinhua.
As well as the arrests, the police also seized nine servers, five computers, a Honda Accord and 1.7 million yuan in assets.
