Title:
PSA: Lemmy.world has been compromised!
Post:
FYI!!! In case you start getting re-directed to porn sites.
Maybe the admin got hacked?
Images:
First, some random video show up, I'm not gonna watch it in case its NSFL content.
Second, the website tries to redirect me, but uBlock Origin blocked it
The Front Page
Side Bar got messed up.
Everything else seems fine, here is the signup page with the Lemmy Version visible.
Also notable comment from the Original Post:
Yea, I switched to this alt. It appears to be one of the assistant admins accts. Seems like an old fashioned anon prank, to me, they’re mainly just trying to make stuff offensive and redirect people to lemonparty.
So, y’know, old school.
I don’t know if any data is actually in danger, but I doubt it. I don’t see why assistant admins would need access to it.
Edit: Someone else said an admin's credentials was compromised:
One of the admin accounts appears to have been compromised. The owner/other admins appear to be aware now because that account had its admin access revoked and offending posts are being removed.
Definitely opens up a big question about the security of Lemmy instances that I am sure will be discussed over the next few days.
@[email protected] be careful with making admins. And secure your passwords, use 2fa, etc...
Edit 2: Now the entire front page is filled with posts regarding the lemmy.world hack. Interesting...

Edit 3: Lol a post was made from the hacked account claiming the hack was fixed, but that account is still under the hacker's control:
Edit 4: Lol this is actually funny:
"Site has been seized by Reddit for Copyright Infringement" Lmfao
Edit 5: threads was put on an allowlist, and lemmy.ml was put on a block list, every thing else is under "linked instances". I wasn't quick enough to get a screenshot or an archive link.
Edit 6: lemmy.blahaj.zone just got hacked too!
I urge all instance admins to temporary defederate from lemmy.world and lemmy.blahaj.zone as a safety precaution.
It's a significant XSS vulnerability in lemmy.
One of many nice aspects of the fediverse, it's not a software monoculture that can be wiped out by a single exploit.
But on the downside, as long as it is a vulnerability that's not instance-specific or could be federated, you'll have to investigate not one network / database / server cluster / software stack / user group / etc., but possibly hundreds or thousands, operated by mostly amateurs with very different levels of knowledge, living in very different time zones, having different availability.
