Monero black marble 0day attack guide? Real or nah?

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

  • 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

    • 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.

        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.

      • 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?

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