My first comment here I couldn't get my post to submit on reddit (don't like Tor IP?)

I was browsing X on my phone searching for monero tags to catch up on news and it popped up on my feed no likes no shares. Real or fake? Wth is this antidarknet stuff? Something monero developers should be informed about or nah? anyone tried it?

I couldn't submit to archive.org the link here's what it said

Monero 0-day. The Black Marble Attack. How we did it

It doesn't seem actionable. They spent 30,000 US to generate a bunch of traffic, which slowed down transactions. Well I don't appreciate the sentiment, these attacks help evolve the network infrastructure to become resilient

If you want a visualization on the transaction backlog

[–] joe8961@monero.town 1 points 3 months ago (14 children)

How can it be not actionable but slow down transactions too? I remember when i wasn't able to submit transactions for many hours on end. Wasn't the black marble attack exactly slowing down transaction? seems contradictory to say it wasn't actionable if its end result? i am confusion

They claim they've made-off several illegal markets over 300k i mean that's a 10x investment don't know if they care about the initial 30 grand lol

I totally agree resilience is needed on monero and if it's how the attacks were done it could give developers insight how to fix it. Almost seems like a simulation where many more people would use xmr. More confusion should we thank them or tell them to go f themselves??

[–] admin@monero.town 4 points 3 months ago (1 children)

This attack highlighted several issues that have been addressed. The biggest issue was wallets not automatically raising the default fee which led to transactions getting stuck for hours. Without the bug, you would have paid 2 cents instead of 0.5 for a transaction and it would have been confirmed at regular speed.

[–] joe8961@monero.town 2 points 3 months ago (1 children)

What you're saying is it's a legitimate attack at the time of executing pre-new build that fixes the bug? Not a fake and they could've really made money exploiting it in badly coded illegal markets? Thanks for clarify

[–] admin@monero.town 2 points 3 months ago (2 children)

They made money through extortion, not by draining any wallets due to spam. There was spam and it did delay transactions for regular users due to existing wallet bugs that are now fixed. I can't really comment on badly coded markets, I assume they somehow broke their payment systems because they didn't account for long delays when receiving coins or also had the fee selection bug.

Official antidarknet admin here.

You seem very certain the attack has been "patched" and we made money from "extortion"? Where are you getting your information from while answering with such certainty? Really curious. I'm not being offensive here but is really not good especially for a website admin to make high speculation when they don't know the facts.

Let me tell you how it really is and then you and everyone else can draw own conclusions.

Fact #1

Although the bug was patched officially it's still possible to do what we described in the post on our forum. Try it out and see for yourself. Automatically setting the fee doesn't make the problem go away if you're 300 blocks or more backlog. As an attacker setting high fees and spamming it DOES create backlog too albeit slower. We do agree it could've been the case of the market wallets not being updated hence not being able to send transactions and falling under our exploit scope. Some of our attacks were after the patch was deployed evident by the timeline of certain darknet marketplaces collapsing.

Fact #2

We never extorted nobody we simply took it from criminals extortion means something else. You say we "extorted" but in the next sentance you say "they somehow broke their payment systems"? You're absolutely correct we did break their payment systems but not because they didn't account for long delays or because we "extorted" them (we never communicated we just did our exploit). But reason being when markets were executing sending payments functions (withdraw for clients) they hadn't accounted for the sending itself to fail due to the huge backlog we were creating with the spam. Creating an account and depositing then withdrawing while spamming Monero network resulted in getting multiple times the same amount over and over. Simple and honestly newbie programmer mistake not to cover use cases that cost them in total 300k+ and lead to several of them shutting down.

Fact #3

Our mission statement is crystal clear. We never took any profit from these attacks. All money were and are being put back into our new projects and operations which are ongoing targetting darknet markets, forums, fraud shops and so on.

We appreciate the discussion and do hope sincerely the monero devs to be notified, do simulation tests on that stressnet that was build specifically due the attack and see what we're talking about is not theory in any way and still possible today with enough resources (not talking crazy amounts here less than 100k).

As a bonus to the developers if you're reading this is the official wallets are extremely unstable at 200,000 subaccounts if each has had at least one transaction in and one out. Try generating more subaccounts after 200k it takes many times longer to generate rather than when first initializing a wallet. The more accounts you add the slower it gets. Should probably fix that too. Don't take our word for it but test it yourselves.

We fight the illegal use and not against privacy featured coins like Monero that's why we're sharing all of it. We did indeed use it and possibly cost inconvenience to users however taking down illegal markets where hardcore substances are sold is a priority over making a payment now rather than in half a day.

Yeah sorry, I had not considered draining market wallets as an option. Thanks for the pentest, it greatly pushed FCMPs and high-throughput research forward!

[–] antidarknet@monero.town 4 points 3 months ago

Good to hear we never intended to hurt any legitimate Monero users. That has been said so many times already even on our latest clarification topic (for the thickest of users) https://antidark.net/board/viewtopic.php?t=15 hope you don't mind posting this link twice. We very much like this site better than Reddit.

[–] c0mmando@links.hackliberty.org 4 points 3 months ago (1 children)

as if dealing with the feds wasn't enough, now we gotta deal with hacktivist bootlickers

[–] antidarknet@monero.town -2 points 3 months ago (3 children)

Unless you're criminal you shouldn't be worried in any way. We support privacy (disclosure of bug) and agree darknet communities should exist but not when they break the law. No sane person can argue selling h**oin or someones bank account details is something noble and we should all be very upset about it when its disrupted. Unless you are one of them.

[–] blake@monero.town 6 points 3 months ago

hi antidarknet

cool site and nice job stresstesting XMR. look forward to seeing more of your projects in the future!

Makes me wonder about other vulnerabilities there could be - particularly regarding dark markets, xmr escrow services etc.

regarding your point

Unless you’re criminal you shouldn’t be worried in any way.

A criminal is someone defined by the state as having broken a law. Likewise a legal action is one which happens to coincide with a state's edict (law). but libertarian maximalists or anarchists wouldn't agree. hence why you were called a bootlicker.

whilst it's perfectly righteous to fight what you see as harmful, there's an argument for freedom, particularly in the case of drugs where it is usually the user who is the only one at risk of harm (if we follow the harm principle rather than legal/illegal). yes the drug trade can harm too - but that could also be because it is 'illegal' and has to take place in a non-ideal marketplace.

that being said, I have my own limits as to what is moral so I agree that you should pursue yours. but I will do things that are illegal, and I encourage you to do so too. perhaps one day using monero will be 'illegal'! </end philosophical sidebar>

[–] c0mmando@links.hackliberty.org 3 points 3 months ago

I'm not worried.

darknet communities should exist but not when they break the law.

You all just sound like a bunch of wanna-be cops to me.

No sane person can argue selling h**oin or someones bank account details is something noble and we should all be very upset about it when its disrupted.

Actually any sane person could argue that PROHIBITION does not work, and by attacking darknet marketplaces what you're doing is making it so drug addicts need to take even more risk buying random shit from street vendors instead of vetted dark web marketplace vendors.

I don't think any of us support your virtue signaling, go attack some child predators or something.

[–] antidote@monero.town 1 points 3 months ago

As @Blake said, "breaking the law" just means going outside of the boundaries set by your rulers. For anything outside the law, your rulers dislike it, but the majority of people could actually like it.

Take going to the bar with black people as an example. You might be in a place where it's disliked by the ruling political elite, or in a place and time where it's fine. This is the legal/illegal view.It's sometimes quite different from the moral view of things. The same applies to other topics like should women be allowed to drive cars, or should drug addicts be allowed a safe source of drugs free from the influence of "very bad people"?

Please don't let political elites set your personal morality. They are professional liars ( that's how they became political elites) and they have no morality to offer you.

Thank you for helping to make Monero the best digital cash it can be for me to use on whatever I want.

The publicity you generated with this is worth at least 1000 XMR, keep at it! 😍

[–] joe8961@monero.town 2 points 3 months ago (1 children)

I'm seriously getting confused here sorry how didn't they make money with the attack but through extortion? Did they break payment systems with monero slowdown or they slowed down monero and extorted money or they extorted money not to attack the monero network? I cant find what you're referencing to

If they were able to use it as attack doesn't that make it actionable and jet who commented wrong?

[–] admin@monero.town 4 points 3 months ago

I was wrong, I didn't consider that their attack could drain badly coded DNM wallets by double-spending withdraw transactions.
