This tactic is somewhat novel in the memcached ecosystem, but is not entirely unique to Gear6's product. Sun engineer Trond Norbye has done some experimentation in this area and will be speaking ...

Memcached amplification factor can reach a massive 51,200 According to Cloudflare, Memcached-based reflection DDoS attacks can have amplification factors up to 51,200.

The memcached systems then return 50 times the data of the requests back to the victim. Known as an amplification attack, this type of DDoS has shown up before.

Running Memcached on the same machine as mod_perl works well, because our mod_perl code is CPU-heavy, whereas Memcached hardly touches the CPU. Certainly, we could buy machines dedicated to Memcached, ...

The 1Tbps-plus memcached amplification attacks that hammered GitHub and other networks over the past week can be disarmed with a "practical kill switch", according to DDoS protection firm Corero.

By transitioning to Memcached running in-process within our existing App Service plans, without any additional infrastructure, we eliminated the need for Redis Premium entirely.
