Former infosec worker here, my 2 cents on this:
>4chan was running on an EXTREMELY OLD version of php so it was vulnerable as fuck
>hacker found vulnerability back on 2021 and played the long game so they could take down the entire site
>alongside admin info, entire source code leaked
>site used deprecated connections to MySQL server, insecure as shit
>site had a file with whitelisted countries that could post freely while others needed to wait for 900 SECONDS TO GET THE CAPTCHA.
>whole code base needs to be updated in order to get the server running up again, which could take a long long time, and could be deemed not worthy by Hiro, so this may actually be the end of 4chan
Remember kids, update and patch vulnerabilities if you don't want to get nuked out of the face of the earth by the hacker known as 4chan
