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.

Github Issue created here: https://github.com/LemmyNet/lemmy-ui/issues/1895
Compromised in what way? Can you post proof?

among several others
Could you spoiler that weirdo image
How do you spoiler an image in Lemmy markdown?
It works like this
spoiler test
Test
I can’t get it to work on an image. Is it 4 underscores?
sorry for this being so hectic, I was walking back to my apartment trying to do all this on my phone lol
It’s 3
3 underscores did not work in preview, I’ll just leave it as is now, a clickable link (not rendered inline)
The image isn’t spoilered? lmao
I wasnt trying to spoiler that image
Huh, ok I guess.
I’ll try it myself here
spoiler
Yay it works :D
Are you on an app? It’s this symbol on lemmy
Looks like this if you need to do it yourself
I don’t think it works on an image?!
Works like thistesting spoiling an image
Just go to lemmy.world and see for yourself. (Or don’t actually, might give you a virus or something idk)
Yeah I would like someone to post a screenshot i dont want to leak my ip
Just go to https://lemmy.world and see for yourself, although be careful it’s nasty.
As of now it looks like this:
And then it randomly redirects to gore sites like lemonparty or chaturbate or some pedo shit. It’s pretty bad.
Alright thanks
Hmmm. Don’t know what the fall out of this will be. But a lot of lemmy is on that server. Unfortunately. Maybe we’ll learn a lesson in the value of decentralisation.
Ruud also runs mastodon.world, FYI.
This is why it makes sense for communities to not all pile into one instance, it gives one instance admin too much power and responsibility over everything.
Looks like this thread is getting mass downvoted by bots btw

It looks like they’re in the process. The compromised account was demoted from admin and I see posts are being removed. There will definitely need to be some sort of investigation into how this happened, though.

The “Hot” sort topic:
For those not aware, the beehaw server did intentionally shut their instance down to avoid any issues.
See announcement here: https://hachyderm.io/@beehaw/110687918465426082
God damn, spez-funded hacker groups already is trying to disrupt the resistance.
Fuck spez
This is going to turn into some obligatory response.
“Thank you everyone for coming together to discuss the planned future for the news community.” Everyone: “Fuck spez.”
Being a part of Lemmy in these early days has been kind of interesting, seeing all of the bugs and bits that will be ironed out over time. One day when Lemmy is as old as Reddit it will all be folklore. Maybe.
This’ll definitely be remembered. It’s good for us, we needed the wakeup call.
GitHub PR fixing the bug: https://github.com/LemmyNet/lemmy-ui/pull/1897/files
If your instance has custom emojis defined, this is exploitable everywhere Markdown is available. It is NOT restricted to admins, but can be used to steal an admin’s JWT, which then lets the attacker get into that admin’s account which can then spread the exploit further by putting it somewhere where it’s rendered on every single page and then deface the site.
If your instance doesn’t have any custom emojis, you are safe, the exploit requires custom emojis to trigger the bad code branch.
But won’t custom emojis from remote instances still trigger the exploit?
Apparently the custom emojis are rendered as static images when federated to outside instances so it’s clean.
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.
All the bean memes are in danger! On a serious note, old-skool or not, it’s a huge loss of trust in something the community-at-large is excited to see replace reddit.
On the other hand, look at where we are. This is proof that one hack can’t take down Lemmy.
True that. If you look at posts on lemmy.world though, it’s clear their users (which is like 50% of Lemmy) have zero clue they’re defederated ATM, and probably many that don’t know it’s compromised.
Federation and decentralization are not Web 2.0 concepts. Just like people who first learned what a tweet and a follow were and all the other concepts of those social media platforms, they’ll learn the new paradigm. Or they won’t and we’ll stick to 2.0 platforms.
Par for the course. This system will never be immune to things like that. That’s part of what happens when you decentralize your power. Instead of a single target that can be made highly secure, you have a distributed array of targets.
People should certainly be engaging on here with full awareness of the reality of the Fediverse, not expecting reddit 2.0. We never will be able to offer exactly what they did. We’ll be naturally worse in some areas and naturally better in others.
This is why I’m glad I made redundant accounts on multiple instances. When there are problems on lemmy.world, I can just hop on over to another. That’s never been an option with Reddit.
Now if there was only a way to export or sync user settings like subscriptions, it would be perfect.
There’s actually another thread on exactly this topic: https://lemmy.ml/post/1875767
idk, im surprised it took this long. there’s a huge variety of admin teams with varying degrees of security awareness and it’s been over a month since the first big influx of users started. it’ll happen again too and probably not before too long
In the 3 years Hexbear has been around it has been attacked A LOT because obviously far right chuds have an interest in messing with leftists but has not to my knowledge had an admin breach. At one point image embeds were completely disabled because they were handing over data they shouldn’t though and risked exposing people to doxxing.
I really hope they have backups in place.
I was once doing work at a company that provided tech support and security for local businesses. There were a couple big instances of the companies being hacked with ransomware etc. On every occasion, we of course ask, “when was your last backup done?” And without fail, every one of them always responded, “backup?”
Good ol’ FAFO
lemmy.world was briefly back to normal and there had been a post saying that everything was fine now - it’s not.
The site has just started doing the same thing again.
Please do not try using lemmy.world for the time being.
the post saying everything was fine now was coming from the same account that was originally compromised
Lol so how do you expect to be notified then? You don’t think they can get their account back? They’ll get it back eventually.
They have multiple admins. The expectation would be for one of the non compromised admins to make the announcement. It’s a trusted channels thing
