A enormous data leak from a Chinese cybersecurity firm has offered a rare glimpse into the inner workings of Beijing-linked hackers.

Analysts say the leak is a treasure trove of intel into the day-to-day operations of China’s hacking programme, which the FBI says is the biggest of any country. The company, I-Soon, has yet to confirm the leak is genuine and has not responded to a request for comment. As of Friday, the leaked data was removed from the online software repository GitHub, where it had been posted.
