i found a nice tut that helps u with the basics of the botnetsIn addition to Rxbot 7.6 modded in this tutorial, you can also use another good source. It is rx-asn-2-re-worked v3 is a stable mod of rxbot and it is 100% functional and not crippled. If you want to download it, you can below:

Download
Compiling is the same as it would be with Rxbot 7.6. I prefer this source but it would ultimately be best to compile your own bot/get a private one.

Q:What is a botnet?
A: A botnet is where you send a trojan to someone and when they open it a "bot" joins your channel on IRC(secretly, they don't know this)Once done the computer is now refered to as a "zombie".
Depending on the source you used, the bot can do several things.
I myself have helped write one of the most advanced and secure bot sources out there.
(Off topic)
But once again depending on the source you can :
Keylog their computer, take picutes of their screen, turn on their webcam and take pics/movies, harvest cdkeys and game keys or even cracks, passwords, aim screen names, emails, you can also spam, flood, DDoS, ping, packet, yada yada, some have built in md5 crackers, and clone functions to spamm other irc channels and overrun a channel and even perform IRC "Takeovers".
Once again depending on the bot it may be able to kill other fellow competeter bots.
Or even kill AV/FW apon startup.
Add itself to registry.
Open sites.
Open commands.
Cmd,
notepad,
html,
Anything is possible !

Theres the infected computers "bots" the attacker, the server, and the victim.




Botnets are being used for Google Adword click fraud, according to security watchers.

Now enough with all the quotes. As you can see, you can do anything with a botnet. Anything is possible. This is my bot and tutorial. You can host your bots on irc on a public server but I would recommend a private, password protected server. I will setup bots for people if they have something to offer.

How to secure your bots:

Don't be an ~censored~, it is easy to steal bots. All you need is the irc server address and maybe a key.
To steal bots, watch for the @login key one must upload their bot to a direct link (tdotnetwork is execellent)
and update the channel topic and run:


The http://mybot.com is your bot's download link and the 82 can be any number(s)
Now steal their bots and have them join your channel
To find the server address you need their botnet. Then take their bot and open it in the server editor. Address will be shown and so will password and other needed information.

To secure your self:

It is fairly easy to secure your bots, here is how:

1. When you are in your right click on your chat window and select "Channel Modes"
2. Make sure these options are checked:
This way no one besides you or another op can set the channel topic
Note: Setting "Moderated" is good for when you are not there because anyone who is not voiced (+v) or and op (+o) cannot talk. They will still log in and follow commands however there will be no output.

Good IRC Servers:

I would recommend running your botnet on a private server.
If you would like to setup a botnet on a certain server, do not intrude and make one. Talk to the admin and make sure he know that the IRC server is not doing anything illegal. If an Admin refuses, don't get angry. It is his/her server after all
