cross-posted from: https://quokk.au/c/fediverse/p/1066667/tesseract-dev-injects-malicious-code-into-browser-to-illegally-ddos-the-dbzer0-instance
As part of the devs farewell message on their site, they have included malicious code to make each visitor sends 2,000 requests to the dbzer0 servers in an attempt to DDOS and take the instance offline.
dubvee.org is down
what does dubvee.org have to do w it?
That’s where the ddos originated
What the actual fuck? This idiot may have his braindead opinions and do to his OSS project whatever he wants (so sag I wasn’t on the list), but that is just such a fucked up thing to do.
@db0@lemmy.dbzer0.com You need to see this
Already known and mitigated.
I am not sure what the other preventative actions have been taken. Is it feasible to defederate from this and any other instance that is administered from this person who has virtually attacked the flotilla?
The website has been taken down so that particular vector has been removed. The related startrek.website instance defederated from db0 and other instances have defederated from st.w due to all this.
The individual had at least 2 known alt accounts, so it’s likely they have more and will pop back up like a noxious weed.
Not to expose anything that’s best left internal, but is this something the proof of work check handles? Is it something that’s been implemented in advance? Just curious, if you can talk about it at all. I’m woefully undereducated on the actual ins and outs of the web.
For this kind of stuff you can easily ask an llm and it will give you a pretty decent rundown of mitigation tactics
Just thought it would be the cherry on top if this final outburst was automatically blocked by a mitigation measure that was already there.
They can block requests from a specific origin or implement tailored rate limiting rules or disable CORS from that instance. Probably more too
The problem is that this is a client side javascript-based attack - meaning your browser sends these malicious requests. So a DDOS, not “just” a regular (centralized) DOS. Anyone opening the page with javascript turned on (which is 99% of real users, however for Lemmy the statistic’s surely a bit better) is an “attacker”.
You can - once you know of the nature of the attack (this one’s relatively simplistic), just react to any realistic-looking request and
blockignore the malicious ones - in this case garbled rng output.Rate limiting would only lead to what the attacker wants - legit users (who are unknowingly sending these malicious requests) being blocked from accessing the site.
I’m confused. dubvee.org is down and the tesseract repo was also pulled. How is this being deployed? What instances are hosting this version of tesseract?
I would like to see this javascript myself because DDOSing with open source code in your name is a whole new level of unwise.
Also wtf is up with the
100 - 1 + 1expression? Is this some weird JavaScript quirk?Dubvee is down down now (server not responding), but prior to that the site had a really bitchy “farewell” message. The DDOS was embedded javascript code your browser would run when you visited dubvee.org and viewed the message.
Archive.org has a snapshot of it, but it still has that javascript embedded so I’m not going to link to it. Here’s a screenshot of the site when this code was included.
Also wtf is up with the 100 - 1 + 1 expression? Is this some weird JavaScript quirk?
If searching online for a JS random number generator code, something like
Math.floor(Math.random() * (max - min + 1) ) + min;is the most common result. If you’re lazy or don’t care, you just fill in theminandmaxand get that100 - 1 + 1I don’t think the DDoS code was FOSS. I think their frontpage index.html was set to a static html file just for the flounce.
Blegh. I made some effort to get to this instance and I’m not even on the list!
Actual lmao
Your link 404s
It just gets worse and worse. I figured that the goodbye message he posted wouldn’t be the end of it. Thankfully it seems to be down now so it’s not causing harm anymore directly but still.
This whole thing reminds me of the guy (Angled/LMAO) 3 years ago that was all butthurt after he got busted trying to take all the good sublemmy names, and responded by posting a bunch of disgusting stuff with alts and DOSing lemmy.world.
This was a blast from the past.
“Tesseract dev found to have world’s smallest and most rancid penis.”
Im sure some shitlibs will still defend this
Where is @Kirk@startrek.website when you need him most?
not convinced that’s not a sock puppet, from all the stuff I’ve seen so far
He kept claiming they’re AP, but refused to provide proof. Not sure but as it happens, startrek.website defederated us as soon as we banned him.
Huh, weird how the framing of the defedederation lines up so well to what ap and Kirk would say.

If you’re not familiar with how Lemmy/the Fediverse works, basically everything you read at StarTrek.website is hosted by us, even if the content originated elsewhere. That means we are responsible for everything here and we have to decide if we are comfortable boosting content from other instances.
If you’re curious, the final straw here was learning that db0 explicitly allows hosting discussions about hurting people, which needless to say goes against our instance values and we simply don’t have the manpower to moderate that volume of content incoming from their server to a degree that we feel meets our quality standards, which left defederating as the only viable option.
In keeping in line with past trends we’re announcing this because is is a larger instance and don’t want to leave any of the crew confused as to why something may be missing.
Startrek.website is probably also run by Admiral Patrick, or maybe he’s just someone with admin access there. Either way they seem like bad news, that site should definitely be avoided.
I don’t think I’ve heard anything positive about the instance so completely unsurprised by what they did AND how they were happy to blame db0 for everything while continuing darvo.
Only sad this comment didn’t federate before the post was locked
So this user of yours will also be banned for not following the instance values?
Specifically not following authenticity, ie saying they’re a different user but could be trying to increase the moderation you may need to do, and extremely disrespectful, unless that value only counts towards members of this instance.
This is being brought up specifically as while yes you are a small instance non of this apart from that user would bring traffic here you would need to moderate so it seems as if you are just doing this to cut off a large portion of the fediverse explicitly against principles those in star trek would be for.
Wow lmao. This is crazy levels of petty
What a loser. Tiny whiny loser.
Fabulous reaction time from db0 & team!
So who is this loser, I mean it’s a tiny whiny bit illegal what he did it seems…
Idk what this tesseract is and at this point I’m too afraid to ask
Thanks mate
Gotta say, I’ve enjoyed this whole drama. This seems like the end of the story arc. It’s been fun guys. Better than beans.
Nothing is better than beans, how dare you say that. The beans can hear you.
I hope it’s the end but like the piefed stuff we think it’s done then something else comes up.
Plus the dev/user/admin of dubvee has said a few times they’re leaving only to be back soon after saying that. Hell there were two or three announcements tesseract work was stopped 🤷
What is the piefed stuff?
the same thing except less well hidden.
Piefed dev doing something similar on the flagship instance, and has some odd philosophies on what should be filtered out in the code.
When people started pointing it out and asking questions called it harassment and tried to get instances to instance ban them all.
Best part was insulting everyone looking at the code if you didn’t ask on their specific comm.
Gotta leave the door open for a next season sequel with a sneaky post credits scene.
Genuinely feel like we’re seeing a mental health crisis or breakdown by the dev…
Yeah, also this makes me really happy that we’re on the fediverse. Turns out some part of the system is run by a strange control freak? Swiftly replace the part and everyone moves along.
Well said.
only works for the ones lucky enough to catch it – a tiny minority is likely considering that piefed was caught doing something similar and it’s still on track to be one of the largest instances on the fediverse nonetheless.
Agreed. I usually don’t care about online drama at all, but at least this has been… amusing.
The memes have been fresh!
You deserve more credit. Thanks for bringing it to everyone’s attention!
The beans have certainly flowed, sheesh.
I dunno, this opens the author up to a lot of consequences other people might choose to pursue.
Ironic Twist:
- It’s a Journey Of The Hero story and this part was just the initial fall of the Hero.
“doubt”
Me too.
It would surely be ironic, though.
