Title: Mtgox's official story could be wrong. The BTC of many accounts was sold.
Post by: ahtremblay on June 19, 2011, 09:47:02 PM
I believe a hacker got hold of everyone's account at mtgox. This hacker then executed a looping script that logged into a number of accounts one by one and issued a sales order for the full BTC balance in these select accounts. After 2 minutes, the loop was completed and all BTC held of the mtgox's clients accounts were offered for sale on the mtgox market.

This drove the price of BTC down to almost nothing. mtgox as a withdrawal limit of 1000$ equivalent BTC per 24 hour period. With the price to almost nothing, the hacker could withdraw almost any amount of BTC he wished from different accounts. I think in a few days or weeks some people will learn they have lost a fortune in this attack.

We must face the reality that mtgox is short on BTC. They do not have the BTC they claim they have.


This is just a warning. I am not saying it is the case that this happened. Just that it is a possibility.

I was watching my account until after this happened and nothing was missing, what you saw is every buy order being executed as a large sell order was filled.

I am stating that a script was run to offer for sale every BTC in every mtgox account.

I am not staying the BTC left mtgox. Mtgox might have been able to shut it down before the person could withdraw sufficient amount.

and you can't have script selling many small amounts only from 1 account?

You have to think here. The passwords/accounts of every account is out! Then you get thousands of micro sales with a bunch of big sales moments before. For a total sum larger than any account in the blockexplorer. Look at the evidence!

You are talking BS, because I was there when it happened, logged on mtgox, and when it was over, my account was untouched.

What you see on that list, is individual bids being supplied by a single sell order.

You wouldn't see one big sell order because there isn't one big buy order.  In order to sell that much BTC, you have to make a transaction for every single buy order that is out there, one at a time.

Sorry OP, but you're wrong.

Not every account would be compromised. Some accounts have stronger passwords and have a salt, making them harder to brute force. But the majority does not.

if someone put in a single order to sell 50,000 BTC at $.01 then however many small buy orders were out there would have all been executed as different transactions, and there would now be thousands of people that bought BTC at prices all the way down to $.01. It is more likely that a single large account created those transactions rather than a lot of individuals accounts.

All leaked passwords are either MD5 hashes or FreeBSD MD5 crypt() hashes. The attacked must have changed all hashes to a known one in order to be able to log into each other users' account. It's not impossible to execute a simple UPDATE query given the fact that the entire passwords database was dumped. Then it would be impossible for you to log into your MtGox account unless the hacker has restored the original hashes.

Those small orders represent the OTHER SIDE OF THE TRADE. The one big sell order was chewing through the open book.

Most people have never tried to code a big exchange market, so they have no idea how they work, or what they look like in action.  Those of us who have aren't fooled.

The exchange has two lists, one for buy orders, one for sell orders.  The order matcher finds the buy order with the highest amount, and the sell order with the lowest amount.  If there is a tie in either of these, it will go to the oldest one.  If there is an overlap, a sale is recorded, balances are updated, the smaller order is closed, the larger order is decremented by the size of the smaller order (or if they were the exact same size, they both close).  Rinse, repeat.

A large order, like selling 500,000 coins for not less than 0.01 $ each, will hit thousands of buy orders, one by one as it chews through the order book.

I don't want to be guy carrying the bad news. Don't shoot me! I'm just the messenger! But I also believe MtGox's coins had been depleted.
MtGox has a 1000 USD limit or equivalent BTC, at 0.01 this means 100,000 btc can be withdraw at once.
By seeing the users file, I come to a conclusion that the attackers could use any number of those accounts, if not all, to trade and withdraw.

This is a snap of bitcoinmonitor during the attack, notice the last transactions leading to the 500K. Looks like the robber getting away with his heist.

... I'm a little bit confused. It is obvious that the stolen database wasn't used to mass sell on every account. Does that mean that the 400k btc withdraw was unrelated? Or it was related in that the owner of that wallet had his password stolen from the mtgox database?

Who made the database public to begin with?

Someone was offering it for sale 17 hours ago here:

and here:

So I think they're well related. Somebody may had buy or the seller himself decided to go for it.

Things are getting clearer.

The hacker has access to many accounts with high BTC. He cannot withdraw because of the limit of 1000$ equivalent BTC. What does he do? He sells offs tons of BTC to drive the price down to almost nothing. Then he empties any number of BTC he wishes. The coins are depleted, many people lost a fortune.

Well I doubt they could get all accounts and know for a fact that mine did not sell any coins, but I also doubt that any one person would have such a huge amount of coins stashed on Mt Gox.  

I am betting either it was one person trying to dump stolen coins or that they hacked a significant number of accounts to accumulate the coins for the mass sell off.  

And what is the 400k withdrawal all about?  


Title: Re: Mtgox's official story is wrong: proof inside. The BTC of every account was sold
Post by: BCEmporium on June 19, 2011, 11:37:15 PM
It was a 500K movement, maybe the attacker merging the coins to his main wallet. Even @0.01 he couldn't withdraw that many.

Have you checked the logon history for unknown IPs? Gmail automatically gives a password change option on logon for everyone whose email was in the leaked database, that's Googles doing in case you encountered it.

Wait, did Google download this list, and then "force" people on it to change password?
My Gmail account had been "compromised" (I don't use the same password, so I don't see how), but perhaps this was just a reaction of the Mt Gox leak?

If so, then this is exactly why I am using Gmail, excellent service!

That graph is pretty damning.  Can anyone think of another plausible scenario for transfering 500k bitcoins?  I don't think there is.  The BTCs were probably bulk transfered out to another account and then distributed out to other accounts soon after.  Unlike with a fiat currency system that people love to deride, there is no compensation here.  No chargebacks.  The BTCs are gone and not coming back.  Worse, whoever has them is sitting on a fortune when markets reopen and can crash the market at any moment they wish.  I fear this hack is the end of bitcoin as a potentially viable commodity/currency.  The confidence in the market is gone.  Why Mt Gox didn't have any protection against this is amazing, as it's a completely foreseeable scenario.

sorry OP your clueless. 

a single big sell order WILL result in thousands of trades. Each trade is a buy limit order that was sitting in the order book.

also, the reason for the big sell order was to drive prices down in order to withdraw BTCs from mtgox, since there is a $1000 a day limit.

Guys, MtGox isn't going anywhere.  They aren't bankrupt, they have plenty of coins to cover the loss, and there's no reason to think that they don't.  You're all just flying around with rumors.

The attacker didn't withdraw 100k BTC.  They first sold everything, bought up a bunch, and THEN withdrew $1000 worth of BTC.

With the price to almost nothing, the hacker could withdraw almost any amount of BTC he wished from different accounts. I think in a few days or weeks some people will learn they have lost a fortune in this attack.

We must face the reality that mtgox is short on BTC. They do not have the BTC they claim they have.

The official story by mtgox states that a single large account was compromised and someone sold everything. This story does not make sense for a number of reasons. First, every account was compromised so why would the hacker limit himself only to one account.

If you were watching the sales order book in real time during this event, you would notice that there were a sequence of hundreds of small sales ranging from 0.1BTC to 2BTC. This is inconsistent with the one big sellout story. The picture below indicates some of those sales. Please refer to this youtube to see how it happened live. http://www.youtube.com/watch?v=T1X6qQt9ONg (http://www.youtube.com/watch?v=T1X6qQt9ONg)

https://i.imgur.com/NDcM4.png

Again this is inconsistent with the one big account sold off story. Many mtgox accounts have small amount of BTC coins left hanging in them (because of a withdraw bug for small amounts). We are seeing these small sellouts in the order book.


TL:DR; If you look at the sales manifest, There are hundreds of 0.1BTC to 0.5BTC sales orders placed one after the other. This indicates that a script is looping trought the accounts and issuing a sales order. If it was just 1 big account, there would be 1 sale for 250k BTC. This fact, combined with the release of all mtgox accounts / password moments later makes it impossible for me to believe in the official story.






The thousands of trades was not from thousands of small sell orders, but from thousands of small buy orders.  "I want to sell 1000 bitcoins for 0.01 btc" ends up being (if there is not one large buy order out), "I've been waiting to buy 10 bitcoins at 17.5, gimme" "I've been waiting to sell 5.4 bitcoins at 17.4, gimme", etc.  All trades happened within a single second, because it was simply the mtgox software looping through buy orders and fulfilling them.

For everyone thinking there is a 1000USD / BTC withdraw limit, I was informed by mtgox that this can be "easily lifted".  I had over a thousand BTC withdrawn within a few minutes by an attacker.


Title: Re: Mtgox's official story could be wrong. The BTC of many accounts was sold.
Post by: relmeas on June 20, 2011, 10:51:57 AM
ok let's look at the official story...

1. selling lots of BTC for 0.01, price lowers to 0.01 but all BTC are sold.

2. for gained $$ buying from available sell orders to spend all gained $$. this drives price back into $17+

3. moving obtained BTC out with $1000 limit which is around 50 BTC now since he bought from really expensive sell orders.

so anyway, what was the point in this? I don't see why would anyone do that .. why not instead sell SOME BTC and when the price is sufficiently low, withdraw remaining BTC.

so either hacker is pretty dumb or some info is missing here.

Would that have worked? How is the withdrawal limit calculated - spot price or some weighted average? It's also possible this was all done to stress the market, for what purposes I'd rather not guess at. Or maybe the perpetrator(s) really were pretty stupid. Not enough info at this point to conclude much.

I guess that 1000 USD equivalent limit is based in MtGox Last.
And that 100~200 btc isn't what the blockchain tells us. Could happen for some coincidence someone was moving all that amount of btc at the same time, but once the transactions are given order to enter the blockchain there's no roll back possible. My estimation, based on the blockchain, goes to 500k, a btc worth of nearly 7,5 million usd.

Mtgox keeps most of his users' BTC balance in an offline wallet.

There is only so much the attacker could have stolen from the wallets on the server.  Definitely less than 500K.

No, on the interview, it was said to be 100 to 200 BTC.  Others have posted that the limit was based on a weighted average, probably for reasons just like this.  A weighted average seems to match up pretty well with the 100 to 200 claimed.

the 500k transfer was Mtgox transferring to a backup as a security precaution.

Not buying that one. Trade halted nearly 15 minutes after that transfer. He would halt trade as first measure.

Why halt trading first? Rolling back fixes the trading. You can't get the coins back after they are transferred.

The #1 priority is to protect the coins.

I know you guys want to keep optimistic, but I'm naturally pessimistic. Sorry for that.
I don't stick to Murphy's law, don't think that if something might go wrong it will go wrong, but always like to be prepared for the worse scenario. Just because I believe that this way I might be happy if I'm wrong but also not fail to despair if I'm right.

@kjj,

It's not a matter of read minds, a thing I can't obviously do, but a matter of reading timelines, a thing I can perfectly do.

@xenon481

While trading was live, people was trading and withdrawing. Mind to tell me where that is to protect whatsoever?! That 500k move was within the time between the start of the attack and MtGox to noticed it, not a MtGox move. If you want to believe it was something else think it was some unrelated movement by coincidence to happen at such time.
That's the best possible scenario, not "MtGox's Star Trek security" which he hadn't, most likely he just uses bitcoind as database, there's no bitcoin fractional reserve nor bitcoins even exist offline for he to put them there. Offline he probably have wallet backups, which are pretty much useless now.

Also to notice, when Jed made it, bitcoin was a pennies pet market experiment, not the million dollar market it is today.

there might still be a rather large loot, but the 500k transaction was not part of it.

@kjj,

No, you read a timeline, and then you read his mind to find out what he really would do, and you drew a conclusion based on the timeline not matching the results of your psychic probe.
