Ability to hack other Computercraft computers

You can already just write a virus, and Anti-Virus is near impossible because startup can be bypassed with a floppy disk.

Viruses are impossible because startup can be bypassed with a floppy disk.

Security holes don't make for a good default state, and your average player wouldn't have much interest in having them. I hence wouldn't expect such a thing to be added to the main mod any time soon.

But I suppose someone could create a resource pack for an adventure map or something, if they had the interest - this is the thread for such suggestions.

That makes it pretty hard to create code that can't be removed from a system, yes, but it's still quite possible to write code which spreads itself over any startup files it can find once it's executed.

it can always hide the file by modifying fs and then catch events and send the files to the writer.

After playing the game Hacknet I think that computer craft could benefit from a hacking interface for it, whether on a treasure disk or by default, the ability to find other Computer craft computers and accesses their files would be cool and could bring up another way for Floppy disks to be used for marketing, mainly antivirus softwares or advanced codes. Please leave a reply on how you think about this.

REAL hacking relies on vulnerabilites in software to gain unauthorized access to something.

Ya what quartz said. real software hacking is exploiting a programmer's weaknesses and using it against them. want to hack someone's CC pc? exploit their bad code

does their rednet system transmit command in plain text? add: ") shell.run("rm startup") shell.run("pastebin get (link to infected startup) startup") where their code was supposed to be to inject some nefarious code
does the player leave files backed up on a floppy? steal the floppy and look for vulnerabilities

etc etc

I made a virus that infected any files and overwrited some functions, the result is total nonsense, pc is doing weird stuff… except you can bypass it with a floppy.

I've cleaned up some misleading/inaccurate posts from this topic.

I find this to be intriguing enough. Someone could possibly make a program to emulate Hacknet (I found the game kinda fun) and thus any other computers running hacknet could be "hacked" and a sort of map could be made utilizing this. Or you could have it to where like hacknet, everything is static, and the player needs to follow some words/rules. tbh, sounds like a fun project, but at the same time, an annoying one if you try it.

I had a grayhat (well, actually redhat) friend who found a vulnerability in jlua a long time ago. It was a basic buffer overflow to execute bytecode on the jvm. It would crash or glitch the server most the time (I think because he was messing up the main server thread). He never gave me the source for it, but I watched him use it, it was pretty impressive.

You guys are mentioning how viruses can easily be deleted from the pc, but a good virus is never found. Aka the player won't know to delete the virus if he doesn't even know it's there ;)/>

This is a unique idea, although I don't quite understand it.
Anyway, you can reproduce similar effects with CCTweaks, as it allows disabling startup from disks. The whole remote file access thing sounds very easily exploitable on servers though.

Notice how the latest versions of computercraft have an option to disable disk-startup?
Here's my thoughts on the matter:
Computercraft is for creating programs, not griefing other people's precious creations.
