Hackers send cryptocurrency exchange offline with DDoS attacks

Someone is disrupting cryptocurrency exchanges with Distributed Denial of Service attacks, with both Bitfinex and OKEx hit in the past 24 hours.

“I was not aware of the attack against OKEx yesterday. I’m interested to understand similarities,” tweeted Bitfinex CTO Paulo Ardoino. “We’ve seen a level of sophistication that means a deep preparation from the attacker.”

Seems the real attack. Attacker showed us his hand and allowed us to quickly prevent this from happening in the future, no matter the scale.

While I’m saying this I’m touching balls (as we say in Italy) or touching wood.

While OKEx remains largely unaffected beyond, trade on Bitfinex was suspended for around an hour, cryptocurrency news outlet CoinDesk reported. Both exchanges are currently online.
