Bitfinex, OKEx Suffer Fresh DDoS Attacks

Two major digital asset exchange - Bitfinex and OKEx - have experienced Distributed Denial-of-Service (DDoS) attacks recently.

OKEx announced the attacks on Weibo, while Bitfinex took to Twitter to make the news public.

The attacks targeted Bitfinex around 9:20 am (UTC), but the exchange has already resolved the matter and resumed its services.

"Services on the Bitfinex platform have resumed. We implemented a stricter protection level as a result of our platform coming under a Distributed Denial-of-Service (DDoS Attack DDoS Attack A distributed denial of service (DDoS) attack is defined as an attempt by malicious actor to overwhelm a targeted server, website, or network with a flood of internet traffic.

All issues relating to the DDoS attack have now been resolved," the exchange noted.

OKEx, on the other hand, experienced the attack last night. The support team of the exchange was quick enough to detect the attacks and also resolved the issue. It also assured that no clients were affected.

"Competitive products and technologies can't compete with OKEx, so they bought DDoS ​​at night to attack Kazakhstan," OKEx CEO Jay Hao noted (a rough translation from Mandarin to English) on Weibo. "It doesn't matter, OKEx Global Technology Department is on duty 24 hours a day, and completes the anti-D traffic switching in minutes. In addition, this large-scale DDOS attack and alarm processing, don't get too frustrated."

A move by the competition?

DDoS attacks are a malicious attempt to disrupt normal traffic of a targeted server, service, or network by overwhelming target infrastructure with a flood of internet traffic.

Hao is also hinting that the attack was orchestrated by his competition.

"Don't be too furious when someone from a friend's technology department buys a DDoS ​​attack. It's easy to trace the source of such a large amount of traffic. Don't regret it when the police came home suddenly," he added.
