4chan was reportedly hacked Monday night, with rival imageboard Soyjack Party claiming responsibility and sharing screenshots suggesting deep access to 4chan’s databases and admin tools. Ars Technica reports: Security researcher Kevin Beaumont described the hack as “a pretty comprehensive own” that included “SQL databases, source, and shell access.” 404Media reports that the site used an outdated version of PHP that could have been used to gain access, including the phpMyAdmin tool, a common attack vector that is frequently patched for security vulnerabilities. Ars staffers pointed to the presence of long-deprecated and removed functions like mysql_real_escape_string in the screenshots as possible signs of an old, unpatched PHP version. In other words, there’s a possibility that the hackers have gained pretty deep access to all of 4chan’s data, including site source code and user data.
