Hackers used transaction malleability to steal BTC from exchanges (yes, plural, it's not only Gox, read the Bitstamp statement)

Consequence:
1. Exchanges have the fiat they say they have
2. Exchanges don't have the BTC they say they have

Conclusion:
1. Some users don't have reported BTC on exchange they think they have

Speculate how this could be solved

Sure, they can say whatever they want, but read between lines, this is from their statement:

Quote
Currently it has suspended processing Bitcoin withdrawals due to inconsistent results reported by our bitcoind wallet, caused by a denial-of-service attack using transaction malleability to temporarily disrupt balance checking.

I'm not talking about BTC withdrawal, sure all of them will fix that, I'm talking about BTC missing from exchanges and how will they address that problem.

You're either extremely stupid or trolling or both....

Inconsistent results by their wallet does not mean the bitcoins got stolen. Stupid shit, go read the actual explanation of this "bug" as well as understand completely how blockchain works.

There are no btc missing, except from Gox because of their crappy software that was easily fooled using transaction malleability.

I don't think that Gox is the only one who was fooled by transaction malleability, read the latest Bitstamp announcement:
Quote
Bitstamp, with help from the Bitcoin core developers, has implemented a solution that passes our preliminary tests and audits.

Why would they apply the fix, if their software was good?

Exchanges should address this problem and make official announcement with the estimate of how many BTC were stolen from their wallets.

i asumme they have a huge collateral to cover for those losses ? I mean they have the power to buy at low prices which i think they did in the recent dip, just a thought

The software was vulnerable to DOS attacks.

The exchanges will cover the loss. They make money running their business, remember?

Most likely SR admin stole all the coins himself, using transaction malleability problem as an excuse

Exchanges could conspire to crash the Bitcoin price, buy back BTC on the cheap, and equalise discrepancies between user Bitcoin accounts and actual blockchain approved Bitcoins in exchanges' wallets, and make a profit doing so.....

.....but they would never do that, would they (as if it weren't patently obvious that Gox are already doing it).

Most likely SR admin stole all the coins himself, using transaction malleability problem as an excuse

Yep. All a bit too convenient for my liking. SR 2 and Sheepmarket now. Just lets the world see what a legendary character Ross Ulbricht was. He could have fucked off with a big pile of everyone elses Bitcoins at any point, but he preferred to keep on running a pioneering and very dangerous business with honesty and integrity. Not many would have done the same in his shoes. Silk Road 1 was a flagship example of how online commerce should be done. As soon I logged into SR2, it became apparently very quickly, just how much dodgier the place had become....and then this.....

Kraken Account, Robbed/Emptied. Kraken say "Fuck you, its your loss": https://bitcointalk.org/index.php?topic=1559553.msg15656643#msg15656643

Bitfinex victims. DO NOT TOUCH THE BFX TOKEN! Start moving it around, or trading it, and you will be construed as having accepted it as an alternative means of payment to your USD, BTC, etc.
