I hope SDC will come out from this XMR attack as strong as before!

Now that Monero has been unsuccessful in their de-anon attempts and FUD I think it should actually strengthen the core idea that Shadow is the real cutting edge anon leader. Good PR for the upcoming releases.

I'd like to thank the Monero Research Lab for the peer review.
Cheers!

https://blog.shadowproject.io/2016/02/12/deanonymize-shadow-nope/

If anyone from the Monero camp wishes to help attempt to deanonymize an actual transaction, feel free.

I just read through this and am slightly confused. It's not clear to me whether a problem exists or not.
All Im getting is:
a) we couldn't de-anon a tx using the vulnerability published after trying for 10 hours. This does not seem exhaustive and the blog shows no fancy maths to prove everything is OK
b) Your NOT gonna award the bounty cause he declared it publicly first.

Am I the only one who thinks more investigation is needed?

They're still testing it. Can't answer your other questions.

The github issue is still "open" https://github.com/shadowproject/shadow/issues/25

Quote from: blog.shadowproject.io
We will of course keep looking into the claim and come up with a detailed report as soon as possible.

official word still not issued

The following quote shows this matter is unresolved:

Quote
Today showed us that public security reports can cause panic and FUD (fear, uncertainty and doubt) among our users, while in fact, the issue at hand might be easily solved by our team members or not be an issue at all.

The word "might" is hardly re-assuring or one oft used by mathematicians.

So isn't the headline Deanonymize Shadow? Nope. misleading when the matter is still unresolved?



Also this discussion https://github.com/shadowproject/shadow/issues/25 is an exchange between kewde (code i guess - who is not a crytographer) and ShenNoether. Ryno's only comment is to say he doesnt know who runs the bounty (and he adds a ty) and no comments at all from the elusive tecnovert (SDC's heralded crytopgrapher whom nobody save ryno knows iirc).

Perhaps I should add that, as I understand it, ShenNoether is some kinda academic/crytographer/mathematician who presumably knows his stuff. Describing him as a "user" in the Research Labs struck me as odd.

The headline bro, it's misleading. I sure hope you wont have to edit it in a few days from Nope to Yup.

No actually they never proved that it could be de-anon'ed. They have effectively failed at that when challenged and now the internal team is spending days trying to prove his theory and are unable to because his theory is bullcrap. And now you are trolling again for an emotional response.

lol

Nobody cares. Your probably right. How sad for you.

Now I'll gladly fuck off since I am reminded of what a nightmare it is posting anything in this heavily moderated thread.

Noone has deleted anything you have said so far. I'm actually impressed you seem more civilized than usual although you completely disregarded my response. HOW RUDE. Tongue

Quite controversial statement. Btw, who is Noone? Some imaginary friend from your early childhood? Grin

You really are below average intelligence, X1235. You are like a racist Kylo Ren if Princess Leia got the Zika virus during pregnancy and passed on Microcephaly.

BAZINGA!

You are not.

The discussion on the github thread is anything but conclusive.

Also "trying for 10 hours" to deanonymize a transaction may mean that they didn't find a particular instance where this problem applies. I'd hate to be the politically persecuted individual who tried to send an "anonymous" token only to get it deanonymized because this particular vulnerability applied to my transaction.

The most likely case is that they couldn't find any transactions to deanonymize because no one actually uses this anonymous system. Probably for good reason.

code: I'm a humble person in contrast to the arrogance in the altcoin scene, I  chose not to declare myself as an expert cryptographer or programmer because I haven't worked with the OpenSSL API or the code in Shadow at all. However I feel completly capable of analyzing the situation and testing if the bug is a reality. Cryptography is a tedious case of testing all components used in the attack vector, in this situation being the generator, hash and the mathematics involved into combining them. While the blogpost points out a flaw in the mathematical relationship between the generator and the hash, we have to make sure that it exists and all necessary components are in place as described within the bug report. I'm not sure about letting a minority of both communities with the same goal abuse this situation to generate financial profits.

A message for Child_Harold,
If you have anything to say about my actions or words, please direct them to me. I don't trust you, or any of your puppet accounts, they are easily spottable by the way. The fact is your approach may be effective from time to time, but it's unethical. If you ever feel about debating your ethics, feel free to quote me.

I've probably made 30 here but they get deleted. Criticism really isn't tolerated here. It shows in the code vulnerabilities.
