Backdoors ?

[hacker95]

ok ive being learning C++ for the last 6 months and i think im pretty ok with it and hacking is a new area to me so id like to start off with something like back doors I really dont know where  to look for info on back doors because i would usually just read books like what i did with c++. Can the info be found on this forum or does anybody know a link to sites where you can learn about these


Hope my questions dont sound too stupid haha

Divide a backdoor in its parts.

1 - It provides a connection. -> Sockets http://beej.us/guide/bgnet/output/html/multipage/index.html
2 - It gives access to a shell. -> choose (Pipes / input-output handle redirection / system()) Google for them.

That is the basic, when you have a working and stable backdoor, you can improve it with data encryption, port knocking, etc.

You should look into programming loadable kernel modules.
