Due to their nature, fork bombs can be difficult to stop once started.

This would have the same effect as a fork bomb and crash the computer.

A fork bomb is a way of stopping a computer from running by making many copies of a program.

Some fork bombs can be stopped relatively easily.

In this case, defusing the fork bomb is only possible if at least one shell is open.

For example, a simple fork bomb using the bash shell script is :

A basic implementation of a fork bomb is an infinite loop that repeatedly launches the same process.

In Unix-like operating systems, fork bombs are generally written to use the fork system call.

Stopping a fork bomb from reproducing further requires the termination of all running copies, which can be difficult to achieve.

A fork bomb using the Microsoft Windows batch language:

One important "feature" in this computer code means that a fork bomb process which can no longer fork doesn't stick around, but rather exits.

To enable or disable shell fork bomb protection:

A fork bomb using the Bash shell:

One problem faced is that a separate program to terminate the fork bomb cannot execute if the process table is fully saturated.

Consider the rather obscure shell fork bomb:

Intentionally leaking resources can be used in a denial-of-service attack, such as a fork bomb, and thus resource leaks present a security bug.

The Rabbit (or Wabbit) virus, more a fork bomb than a virus, is written.

The fork bomb in this case is a recursive function that runs in the background, thanks to the ampersand operator.

A fork bomb copies itself into more then two copies, which then copy themselves into four copies.

As modern Unix systems generally use copy-on-write when forking new processes, a fork bomb generally will not saturate such a system's memory.

An attacker with shell-level access to a victim's computer may slow it until it is unusable or crash it by using a fork bomb.

Fork bombs operate both by consuming CPU time in the process of forking, and by saturating the operating system's process table.

A fork bomb process 'explodes' by recursively spawning copies of itself (using the UNIX system call 'fork(2)').

Fortunately, fork bombs are relatively easy to spot and kill, so creating one deliberately seldom accomplishes more than to bring the just wrath of the gods down upon the perpetrator.

If the new process does nothing, each new do-nothing process we run reduces the number of rampant "fork bomb" processes by one, until eventually all of them can be eradicated.

Of course, there'd be a lot more to the book than rabbit viruses.

Control with rabbit viruses like myxomatosis and calicvirus has been successful in reducing rabbit numbers.

Some mosquito-transmitted rabbit viruses are only transmitted to uninfected rabbits from infected rabbits which are still alive.

They also point to a picture of a horned rabbit painted in the 1500's, but scientists suspect its cerebral protuberances were tumors from a rabbit virus.

In computing, a fork bomb (also called rabbit virus or wabbit) is a denial-of-service attack wherein a process continually replicates itself to deplete available system resources, causing resource starvation and slowing or crashing the system.

The Rabbit virus makes multiple copies of itself on a single computer (and was named "Rabbit" for the speed at which it did so) until it clogs the system, reducing system performance, before finally reaching a threshold and crashing the computer.

It is a known vector of Dirofilaria immitis (dog heartworm); Myxomatosis (deadly rabbit virus disease); and tahyna-virus, a seldom-diagnosed Bunyaviridae, a disease which affects humans in Europe with fever which disappears after two days, but afterward can cause Encephalitis or Meningitis.
