The recent cryptopia hack which crippled the company is just one of the fatal exchange hacks in recent times, even when a plan of action can have helped to at least minimise the effect just like the case of Binance.
The attacker has been around EtherDelta and in most possible case trying to sell the stolen fund.
Whale Alert has reported multiple transfer from the hackers’ account around EtherDelta. The transfer totalled up to 8 yesterday and there have been a transfer today. There were some transfers to an unknown account.
Cryptopia which failed to pick up from the hacking event has since begin liquidation process.
