Simple BOT written in C language

Ethical Hacking Institute Course in Pune-India

Hello guys welcome back to Extreme Hacking programming zone. After looking around in this hacking world found many script kiddies. Useless people using Trojans and Bots made by some one else, hell for such guys. There are tons of people so called security prof.. bla bla bla white hats bla bla..

One question to those money sucking people where do you disappear when country is under cyber threat?? Anyways I dont want these young generation to be bluffed by such peoples. There is no short cut for success.

We need you, this country needs you. keep learning and throw out those tools. Toys are used by kids not by Cyber Warriors.

A simple Bot which can be used on facebook, google+, yahoo msg and any sort of IRC.
Understand the logical flow and create a new one. If you have any difficulty in understanding the logical flow you can write to me at sadik.shaikh@extremehacking.org

Enjoy learning..
