Just after the month after Mt. Gox's permanent fall from grace, came yet another attack on a crypto exchange.

Poloniex was attacked by hackers, and nearly 12.3% of its Bitcoin was ransacked in March 2014.

The hackers exploited a bug in the withdrawal code of the exchange and encashed the bitcoins. To instill confidence in customers, the founder of Poloniex explained how the attack happened and assured that all the affected customers will be reimbursed.
