Everyone, please withdraw everything from Novaexchange - Everything!
Also DO NOT send any coins here! I repeat DO NOT!
ALL TRADES HAS BEEN STOPPED, ANY DEPOSITS WILL NOT BE ACCEPTED! WITHDRAW YOUR COINS NOW!
An vulnerability has opened up for a specific user give themselves an insane amount of Bitcoins. These has been used to trade in the markets, balances has been re-arranged.
All in all, BTC, DOGE and ESP balances cannot be trusted, the vulnerability caused the attacker insert a transaction within deposit systems. But did not think that Novaexchange is a young exchange that doesn't bank a lot of coins. The total volume of BTC in the most important wallet was 3.82 BTC before the attack, not a huge amount but that does not mean it is not painful for some.
The attacker themselves did not get away with anything - actually it is happy users that got traded in ESP market during the last few hours that became happy they sold for BTC and withdrew everything. Which caused the wallet to go empty.
All trades and such is logged and I could technically do a rollback of all trades even if it will take a lot of time to sort everything out. Which would you prefer?
I am concidering to close down the exchange permanently once you have withdrawn your coins, unless the community gives any reason for Novaexchange to stay around. I wanted the site to become a serious player in this business with a lot of alt-coins that other exchanges refuses to trade, that was the idea behind Novaexchange.
