https://wiki.soyjak.st/Great_CucksetThe Great Cuckset (also known as the Liberation of /qa/ and The 'Ack) refers to an event that started on April 14th, 2025 (or April 15 depending on your time zone, it happened at midnight for AmeriGODS), where someone who later named himself S0I1337 (also known as Captain Gem) would hack into 4cuck and reopen /qa/[1], leak the source code as well as the jannies' IPs, emails and hidden board. A thread was stickied on /soy/ regarding this event.[2]
According to S0I1337, it was done by exploiting a vulnerability on 4chan's outdated GhostScript version from 2012 by uploading a malformed PostScript file renamed to PDF to gain arbitrary code execution as 4chan didn't check if files with PDF extensions were actually PDF files, and not through social engineering, betrayal or SQL injection. It was also revealed that 4chan ran on FreeBSD 10.1, which went end-of-life in 2017[3], outdated versions of nginx, PHP and MySQL and its source code was riddled with vulnerabilities; basically it was just waiting to be exploited. The servers were physically shut down to prevent further mining of the databases after a few minutes, although it's unknown at the moment how much was successfully downloaded from 4cuck's servers.
The hacker successfully leaked:
4chan's source code, including a 10,403 line php file called imgboard.php, all of which can be found here -
