Rednet Hacking

Is it possible to use the program "Rednet file sender" to send files that can hack or spy computers? I've already figured out how to send something that has the CIH effect. Remote adminstation or just spying. How to do that?

I'm sure it is possible. However, malicious activity is not a topic of discussion on these forums.

It would have to exploit a program which ran on the receiving computer. Just because you send a message to a computer doesn't mean it has to catch it or even process it.

This.
As in real life, there is no magic "hack computer" button.
Hacking is only possible when the computer is running a program with a mistake (bug) in it, and where the hacker can figure out a way to make the program do something bad (which it wouldn't do if the mistake wasn't there). As such it relies on finding other peoples' mistakes. If you have no idea what's running on the target computer, consider it impossible to hack until proven otherwise.

The only ways to "hack" or gain access to a computer is to either exploit a bug in their system that grants you access or get it to run foreign code. In computercraft, the computers neither have to receive your program, or run it. Also, you have to consider that even if there is a computer that receives, saves, and runs all files, it might not necessarily be in the same format that you send it in.
So in short, it's very very very unlikely to be able to do this unless you have a very trusting person on your server who has a mind that works like yours.

We do not provide support for malicious code.
