Hacks do happen though. i hope this was the case.
Only problem with the hack excuse is there was nothing to hack.. there were no wallets to hack with coins in them yet so what could the hackers actually steal ?
Did you read their announcements at all? The hackers managed to log in to accounts from stolen passwords from previous hacks. Fortunately they discovered that before releasing the wallets. If they had released them, the hackers would log in again and simply send the tokens to their wallets and sell them.
