PSA: Lemmy.world has been compromised! (Edit: Multiple Instances are down)
FYI!!! In case you start getting re-directed to porn sites.
Maybe the admin got hacked?
edit: lemmy.blahaj.zone has also been hacked. beehaw.org is also down, possibly intentionally by their admins until the issue is fixed.

The JWT are likely a hot issue, already some Issues on GitHub about them not being revoked properly.
Oh man, that would be brutal if they are resetting the password and it isn't kicking the attacker out...
That's probably what happened here because they did revoke the admin's access, but it continued.
JWT issue opened 4 days ago: https://github.com/LemmyNet/lemmy/issues/3499
The issue does say changing the password should kick the user out, but yeah, still not good.
This issue from 2 weeks ago was the one I was thinking of, it's worse: https://github.com/LemmyNet/lemmy/issues/3364
Oh man this one is SO much worse. If this is what is going on the only way to kick out the hacker will probably be to manually alter the DB. Yikes.
I hope the admin team is aware of this - not sure how one would even contact them.
Well, provided top level admin access to the server is still protected, a manual DB change ought to be rather doable right?
As for contacting the admins ... the lead admin, ruud, is on mastodon and also admins one of the largest mastodon instances: mastodon.world. They are Dutch however, which means they're likely asleep right now.
All of which raises the broader point about what good admin practice is. This is something the fediverse needs to get better at. In this case, as a bare minimum, every admin should be reachable at a location outside of their own instance.
Ideally, IMO, there'd be an "admin backline protocol" of some sort, where it's super easy or even automatic that every admin of every instance can have an account on any instance they federate with for the purposes of communication etc.
