According to recent reports, Malta-based OKEx was attacked twice, with the first attack taking place yesterday, and the second one targeting exchange again today. The attacks were disclosed by the exchange’s own CEO, Jay Hao, who reported them on his Weibo account.

OKEx did not disclose the attacks on Twitter, but it did hint that a system upgrade for futures and options trading is to take place.

The severity of the attack was confirmed by the fact that the platform went offline for a time, although it returned in less than an hour, reporting that all services are back to normal.
