#15 will not be responded to. This is common practice to prevent people who do not understand the issue at hand from making use of the exploit.

Since it appears Bit_Happy is a journalist, perhaps his question was in that frame of reference? I'll give him the benefit of the doubt.

If that is the case, perhaps a private convo if you're willing would be appropriate, to demonstrate you actually do know what you're talking about and it's a legitimate problem. This would assume Bit_Happy is writing an article on the topic?

Just wild assumptions, it's 1:30am

Now that that's out of the way, back to your regularly scheduled good times!

Please, answer the questions in post #10 and #15, or are you avoiding them?

#10 will not be responded to. If these sources wanted to be named they would have taken me up on my offer to gpg sign the logs. They are afraid of MagicalTux's blamecannon getting pointed their way.

... Or its all fabricated to make TradeHill look more secure in the eyes of the members of this forum.

I do not endorse tradehill. If you read the entire log the person who made the tradehill comments asked that they be removed from the posted log. I refused. I am not a blatant hypocrite.

I do not have a tradehill account.

I do not endorse tradehill as an exchange.

I am not in any way affiliated with tradehill.

I think tradehill is bad for bitcoin because of their blatant disregard for us financial laws and dependence on third world outsourced devs working on closed source software that cannot be publically audited.

Now that that's out of the way, back to your regularly scheduled good times!

Hi Bind link,
Do you know Tradehill is on shared hosting?

... Or its all fabricated to make TradeHill look more secure in the eyes of the members of this forum.

The only reason I say that possibility is because, by their own admission, they checked out all the major bitcoin sites and exchanges for vulnerabilities, and said nothing god or bad about them. Yet, decided to zone in on TradeHill as being the best in terms of security, while neglecting to state why the other did not deserve equal mention.

Why?

If their security was so bad would it not deserve to be blasted like they did mtgox?

If they had good security would they not deserve to been mentioined like Tradehill ?

Plus the request to have TradeHill removed from the logs is quite possible a disinformation ruse to attempt to invalidate the possibility I just mentioned. (like omg, why would i ask for tradehill to be removed if i was whoring for it?)

Regardless of the truth, it will never be able to be "proven" since, even if it is all true, the holes will be plugged by the time mtgox goes live.

Which is what we all want. A more secure market. (minus the drama please)

IMO, Anyone starting a post like this needs to be able to demonstrate exactly where the attack part of this code is:

Code:

If you can show me (us) the "bad parts" and be correct, then thank you for posting this.
If you can't then (at best) you are acting without thinking things through.
Thank you

I agree that everyone should read this.

So, assuming the one 'user' with 500k BTC was MagicalTux, or someone close to him:

1) Gox launches with swiss cheese for security
2) Gox ignores all warning about being vulnerable, and continues to tell users they're safe
3) Gox gets hacked
4) Magical Tux's BTC gets sold for pennies
5) Magical Tux wants to roll back the transactions to get his bitcoin back

Am I missing something?

Magical Tux probably doesn't have 500k BTC. Perhaps everyone on the site combined would add up to 500k BTC. I think every bitcoin on the site got liquidated. So he is backing it out. The problem is whether the coins got transferred out before he caught the transaction.

Praise god I only have a little of my BTC on MtGox.

I guess this teaches us not all use 1 centralized site that used to sell Magic the Gathering cards.

We need about a dozen exchanges each with robust security and FDIC insurance.

Thank you for posting. The theory seems credible and is, at the least, a very interesting read.

Question: what was the purpose of https://mtgox.com/claim ?

I think this is just the icing on the cake, but now there is no allegation of scandal at Mt. Gox, it is fact.

Fact?
What are his two independent sources, and why can they be trusted?
Exactly how do the posted links prove anything, in plain, simple English so everyone can understand, please?

People should read this. All of it, even if it's boring to you.

This is what professional security teams do. They do not blame their users for a hack that didn't happen in the first place (read: a user's account password being compromised likely was NOT the 500k selloff - at least by itself)

As I said in previous posts, the truth will come out one way or the other. MT claiming his site is "safe" pretty much was the writing on the wall in that regard

I've made plenty of stupid ass security mistakes I'm completely embarrassed to admit to. However, I've also admitted my mistakes and made conscious efforts to improve whenever I learn about something new.

Not mentioned here is that fact that dozens of MTGOX hashed passwords were quietly disclosed on a hash cracking forum on Fri Jun 17, 2011 5:21 am
(http://forum.insidepro.com/viewtopic.php?t=9124&postdays=0&postorder=asc&start=75&sid=1a9e31567fe815c0eea63c40c39fb707 post by "georgeclooney")

Since the overwhelming majority but not all of the hashes match the mtgox database that was posted on this forum (now deleted) and elsewhere I suspect that this post may have been generated from an earlier dump than was disclosed on the forums and everywhere else after the big event.

This appears to be significantly ahead of the prior claimed breach, and is consistent with the great many other mtgox users claiming that their accounts were robbed prior to the big event on Sunday, which I believe would have been too early to be results of the mtgox database leak according to the official timeline re: auditor compromise.
