The Qubic mining pool came under a distributed denial-of-service (DDoS) attack when it was attempting a 51% takeover attack on the Monero network. With a DDoS attack interfering with the miner hubs’ attempt to take 51% of the Monero network, the Qubic hashrate dropped drastically. Mining pool controller, Sergey Ivancheglo, stated, “Qubic is under DDoS attack from Monero again (for 6 hours already). I haven’t noticed it because the Qubic pool improved its protection. Let’s see what those desperate guys will manage to break this time.”
With the DDoS attack, Ivancheglo stated, “Qubic pool hashrate peaked 2.6 GH/s before Monero DDoS attacks knocked it down to 0.8 GH/s by making 2/3 of miners disconnect. ”
The Qubic pool hashrate crashed because when a DDoS attack is carried out, an attacker overwhelms the network or the server with massive traffic using multiple devices. Laden by the enormous load, the system crashes, and legitimate users won’t be able to access the network as long as the bad actor decides to keep the network overloaded. These attacks are usually conducted with malware-infected computer networks called botnets.
Ivancheglo suspected that the developer of Monero mining software XMRig, Sergei Chernykh, orchestrated this DDoS attack. Ivancheglo’s suspicions stem from a comment found on Reddit where Chernykh highlights an ethical solution to counter 51% attacks, given that the users of Monero are willing to put a small fraction of the millions they staked in the protocol.
However, speaking to a reputable crypto media, Chernykh denied the allegations and stated, “I’m not behind any DDoS attempts which allegedly happened.”
