Here comes another hacking news related to Bitcoin.  Multi crypto currency exchange Poloniex has announced today that their website suffered a cyber attack, leading to Bitcoins being stolen from their company.

On BitcoinTalk forum, the company explained how hackers stole the Bitcoins; Placing multiple withdrawls requests at the same time will result in negative balance but still the request is being processed.

“Another design flaw is that withdrawals should be queued at every step of the way. This could not have happened if withdrawals requests were processed sequentially instead of simultaneously” the forum post explaining another bug reads.
