Attack
DDoS
Distributed denial of service
Flooding a service with traffic from many machines until it can't respond.
A DDoS overwhelms network links or servers with junk requests, usually from a botnet. It does not steal data but takes services offline; scrubbing services and CDNs absorb most of it.
