Introducing Spectrum: a new Cloudflare feature that brings DDoS protection, load balancing, and content acceleration to any TCP-based protocol.Today we are releasing Spectrum.
오늘 우리는 Spectrum을 발표 하였습니다: 어떤 TCP 기반의 프로토콜이라도 DDoS 방어, 로드밸런싱 그리고 컨텐츠 가속을 할 수 있는 새로운 Cloudflare의 기능입니다.
A friend gave me an interesting task: extract IP TTL values from TCP connections established by a userspace program. This seemingly simple task quickly exploded into an epic Linux system programming hack.
A week ago we published a story about new amplification attacks using memcached protocol on UDP port 11211. A few things happened since then: Github announced it was a target of 1.3Tbps memcached attack. OVH and Arbor reported similar large attacks with the peak reported at 1.7Tbps.
Over last couple of days we've seen a big increase in an obscure amplification attack vector - using the memcached protocol, coming from UDP port 11211. In the past, we have talked a lot about amplification attacks happening on the internet.
