Cloudflare repelled a record-breaking DDoS attack on a Minecraft server

Cloudflare said it was able to repel the largest denial of service (DDoS) attack at 2.5 Tbps on Wynncraft, one of the largest Minecraft servers.

It was a multi-vector UDP and TCP flooding attack that lasted about two minutes.

Cloudflare's Q3 2022 report notes that multi-terabit DDoS attacks have become more frequent.

In the third quarter of the year, Cloudflare prevented more DDoS attacks compared to last year, with a 111% increase in HTTP attacks.

Layer 3 and 4 DDoS attacks have also almost doubled compared to last year, with a 97% increase in frequency.

The most notable region targeted by HTTP DDoS attacks was Taiwan (up 200% QoQ), followed by Japan (up 105% QoQ).

DDoS attacks were targeted primarily at the gaming industry, and increased in volume with the return of the Mirai botnet, which increased its activity by 405% compared to the second quarter of 2022.

Another worrying trend seen in the third quarter of 2022 is the abuse of the BitTorrent protocol. The number of such attacks increased by more than 1200% on a quarterly basis.

The target countries for HTTP DDoS attacks were the US, China and Cyprus, while the attacks at the network layer were mainly targeted at Singapore, the US and China. The vast majority of attacks (97.3%) did not exceed 500 Mbps, and Cloudflare characterizes them as "cyber vandalism".

The duration of the majority (94%) of the attacks was short, less than 20 minutes.

Previously, Blizzard said that the sequel to the team-based shooter Overwatch 2 was subjected to a major DDoS attack. Many players have encountered an error connecting to the game server. As a result, they brought down the rating of Overwatch 2 on Metacritic. The developers apologized to the fans and promised to continue to work on the bugs.
