Hacker QAQ

Five years ago, an overseas APT group called "Butcher" unleashed the "Sea Lotus" supervirus, which spread on a massive scale throughout H Province. The resulting network outages crippled public services, including government offices, hospitals, and businesses. Even the intranet of the troops stationed in the province was affected. The group had exploited a newly discovered zero-day vulnerability sold on the dark web, and it was connected to a girl in the virtual online world known among her peers as QAQ. Was this a coincidence, or was something more sinister afoot?

Five years later, as investigators traced the incident back to its original IP address, the events of that year resurfaced. In the virtual world of the internet, this smokeless battlefield was once again rife with hidden currents.
