Could i release program in Programs?

Hello,

i would like to ask if i could release my ComputerCraft program…
It's Remote Administration Tool or Remote Access Trojan simplier RAT.
I don't know if it can be marked as malicious or not so i want to ask…
I have GUI Client to control PCs running that program like rename, upload, download, shell command.
It works on Rednet.

Sincerely,
B1N4RY

I guess it is malicious.

It just sounds like a GUI version of NSH? A way to access computers remotely. I wouldn't say it is malicious. People could use it maliciously, but that is the case for most things.

I have to say i made it with malicious idea (don't tell me that anyone could think of this app without thinking about malicious ideas) but it could be even usefull for remote help. I am working on RP Server and i am programming Floppy Disks to sell in electronics shop or black market on that Server.

So well, what could be verdict? Can i release it or is it considered as malicious?

And i would also like to ask if anyone could help me with List Clients… I just tried to do something like this

rednet.broadcast("rat:getList")
	local id,message = rednet.receive()
	if message == "online" then
		if fs.exists("online") == false then
			newFile = fs.open("online","w")
			newFile.close()
		end
		file = fs.open("online", "a")
		stringId = id
		print(stringId)
		file.write(stringId)
		file.close()
		
		local file = fs.open("online", "r")
		if file then
		  local i = 0
		  while file.readLine() do
			i = i + 1
		  end
		  file.close()
		end
	end

Explanation: It sends command rat:getList to computers (all connected) and if they reply back with online:{idofPC} then it writes them to file or just list them + count them. (That's what i tried to do)

This is client side (Receiving command)

elseif string.find(message, "rat:getList") then
			rednet.send(id, "online")

I would say that, if there are efforts put into making it transparent, obfuscated, unremovable or hidden as much as possible, then it's malicious.
Although if there's a clear indicator that "this computer is being remotely controlled" then I guess it is okay, otherwise I don't think NSH would be available as a disk in CC…

Okay @Anavrins, thank you for explaining and also

And i would also like to ask if anyone could help me with List Clients… I just tried to do something like this

Could anyone help with that code i posted? :(/>

Well, the main problem I see is that you only receive one message. And you hang indefinitely if no message is received.

Try something along these lines:

local id = os.startTimer( 3 )
while true do
  local event = { os.pullEvent() }
  if event[ 1 ] == "rednet_message" then
    --#handle it
  elseif event[ 1 ] == "timer" and event[ 2 ] == id then
    --#we've waited 3 seconds
    break --#exit the loop
  end
end

Wow, thank you so much. I successfully implemented that into my program… I will give you credits for helping me fix my code (if you would like to have credits)

I did thing to receive all clients once but i had problem with it freezing (forgot to break while).

Rednet.receive actually accepts a timeout option, so you could just do

rednet.receive(3) -- this will wait for 3 seconds, if it doesn't receive a message in that time it returns nil

If you want to know whether or not it timed out or received something check if the things it returned is nil.

edit:

Nvm I figured out what you were trying to do.

I know but it wouldn't help me in my script by any way… Or my other script when it froze
