They are young, gifted and hack - and they want you to know they had nothing to do with the cyber-attacks that prompted Google to announce it was prepared to pull out of China.
They admit some of their brethren waged electronic warfare last week against the Iranian Cyber Army but say members act based on a sense of honour, not instructions from Beijing.
The Honker Union of China was formed after a group of computer hackers caused a stir in 2001 when they brought down thousands of US websites in response to the collision of a US spy plane and a Chinese fighter jet over the South China Sea. Since then, the group has developed into a highly organised network of more than 12,000 individuals who are at the cutting edge of the darkest arts of the information age.
Despite its size and influence, the group is shrouded in mystery. But in a rare interview, days after Google's declaration last week, a core member of the union offered a rare glimpse into the world of mainland hackers.
He and his colleagues were not involved in the attacks on Google - which the US Web search giant says were aimed at accessing the e-mail accounts of Chinese dissidents worldwide - said 'Lyon', who is based in central China and describes himself as a senior hacker.
'We have imposed very strict ethical principles on our members. This practice is not allowed, because it is immoral,' he said.
Google claimed mainland hackers backed by government agencies attacked the private accounts of users of its e-mail service, Gmail, via a computer based in Taiwan, but Lyon challenges this assertion.
