Denial of Service

HowTo : Create a Linux Fork Bomb

Fork bomb is a form of denial-of-service attack against a computer system which makes use of the fork operation (or equivalent functionality) whereby a running process can create another running process.

Fork bombs typically do not spread as worms or viruses, but it works by creating a large number of processes very quickly in order to saturate the available space in the list of processes kept by the operating system.

If the process table becomes saturated, no new programs can start.
