The largest attack was a 2.5 Tbps DDoS attack against the Minecraft server, it was launched by a Mirai botnet.
“The largest attack was a 2.5 Tbps DDoS attack launched by a Mirai botnet variant, aimed at the Minecraft server, Wynncraft. This is the largest attack we’ve ever seen from the bitrate perspective.” states the report published by the company.
“It was a multi-vector attack consisting of UDP and TCP floods. However, Wynncraft, a massively multiplayer online role-playing game Minecraft server where hundreds and thousands of users can play on the same server, didn’t even notice the attack, since Cloudflare filtered it out for them.”
The malicious traffic was composed of UDP and TCP packets, the attack lasted for about two minutes.
