The notorious internet forum 4chan has suffered a significant hack, with internal data being leaked online. Users reported intermittent site outages, and a rival message board celebrated the breach, claiming the hacker had been inside the system for over a year. Screenshots of 4chan's backend, including lists of moderators and sensitive user data, have circulated. A janitor from 4chan confirmed the authenticity of the leaked information, expressing concern over the breach's implications. This incident raises potential risks for the site's moderators and users, especially given 4chan's ties to extremist movements.
