Mysterious attackers have taken down Graviex cryptocurrency exchange over the last couple of days using DDoS (distributed denial-of-service) attacks.
The DDoS attacks took place on Sunday and Monday, December 29 and 30 , and have targeted Graviex’s main exchange website. During the DDoS, attackers successfully managed to overload two of Graviex’s network providers and managed bring down Graviex’ external connections to other ISPs.
The attackers, which appears to actually own a DDoS botnet contacted Graviex’s team demanding ransom payments,but the exchange refused to pay.
As you may've heard #Graviex was under unprecedented DDoS-attack. Now we're online. Btw in a chat while hackers were demanding a ransom (we NEVER paid!), they casually shared their "agenda": @Sistemkoin, @hitbtc, @HuobiGlobal just in case their support will find this info helpful pic.twitter.com/p9nGn6XnXl

At the time of writing, the exchange now appears to be online and fully functional.
A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic.
