In computing, the 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; to incapacitate a system, they rely on the (generally valid) assumption that the number of programs and processes which may execute simultaneously on a computer has a limit. This type of self-replicating program is sometimes called a wabbit.
