    Atleast on WinXP those stop at like 100ish processes, atleast never made me crash... Atleast if you use something lame like

    Code:
    :Ass
    Start blabla.bat
    goto Ass
    Or so it opens like 100 cmds and then just right click and end xP

    Fork bombs are noob etc. but still kinda cool thread

    Fork bombs can be fun, if you can run bash scripts on ssh. Then you can easily crash the servers.

    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)

    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.
    The answer is yes. Kinda. On servers that are running 24-7, this is a serious thread.
    for 'thread' i think you ment 'threat'

    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?

    Edit /etc/security/limits.conf.
    Then add (at the bottom)
    auser hard nproc 50

    format is this:
    <theusername> hard nproc <maxprocesses>

    EDIT: Full article here: http://www.cyberciti.biz/tips/linux-...r-process.html

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