for minecraft server Affected by a distributor denial of service (DDoS (Opens in a new tab)The attack that Cloudflare claims is the largest, in terms of bitrate, has ever been mitigated.
As I mentioned Computerthe attack was carried out by a type of Mirai (one of the most famous botnets in the world), against a Minecraft server called Wynncraft.
Whoever was behind the attack managed to develop a 2.5 terabits per second strike, which lasted about two minutes. It consisted of UDP and TCP packets that were trying to confuse servers and drive away “hundreds of thousands” of players. According to Cloudflare, which defended the incident, people playing the game “didn’t even notice the attack.”
Large DDoS attacks are increasing in number
These numbers are part of Cloudflare’s DDoS Threat Report for the third quarter of 2021. In the report, the company claims that multi-terabit DDoS attacks are increasing in frequency. In fact, during the third quarter, “multiple” attacks attenuated in excess of 1 terabyte per second.
Overall, the number of DDoS attacks has increased over the past 12 months. Long-term volumetric attacks are also on the increase, especially against targets in Taiwan and Japan. In these two countries, attacks grew by 200% and 105% on a quarterly basis, respectively. Furthermore, the report claims that HTTP DDoS attacks grew by 111% year-on-year, but decreased by 10% quarter-on-quarter.
Cloudflare added that Layer 3 and Layer 4 DDoS attacks grew 97% year-over-year, and 24% quarter-on-quarter, noting that threat actors are particularly fond of Mirai.
Commenting on his findings, Cloudflare said, “The attacks may be initiated by humans, but they are carried out by bots — and to play to win, bots must fight with bots.” “Detection and mitigation should be automated as much as possible, because relying solely on humans puts defenders at a disadvantage.”
“Over the years, it has become easier, cheaper, and easier for attackers and hackers to launch DDoS attacks.”
