This is inherently funny because the site where most hacks and breaches appear (like the Nintendo gigaleak and others) got hacked themselves.
Apparently, the hacker had been in since 2021, and they were running an extremely outdated PHP version. The hacker claimed to have full shell access.
But I'm willing to bet this will all be forgotten about in a week.
Currently, as I'm writing the following, I've managed to find:
Source code leaked.
Hacker said they've dumped the database.
Moderators emails leaked (some were using personal emails like .edu).
And likely way more that I myself don't know of.
