That 18k BTC wallet could also be Bitstamp moving coins around or to safety, where's the proof those coins are in the hands of the supposed hacker?

timestamps of the transactions match perfectly with the attack

huge and non standard miner fees

That's not proof. Stamp could have set high fees also to move those coins as quickly as possible after they discovered the breach.

So there's two possibilities:

1) Bitstamp are being stupid
2) Bitstamp were hacked by someone stupid

Well, that's encouraging. Cheesy

Well people generally act stupid in a state of panic. A wallet breach sure must have sent Stamp owners' heart rates to new all time highs. Tongue

no panic dude, that address was collecting bitcoins from compromised bitstamp addresses for 24 h.
