Blackdoor

You're a hacker with a terminal, four terrible scripts, and an anonymous contact who needs files from places they really shouldn't be. The scripts were free. You can tell.

Your port scanner checks all 65,535 ports. That's thorough. It's also going to take longer than the heat death of the universe. Your password cracker uses brute force - bold strategy, shame about the intrusion detection system it just woke up. These tools will technically get the job done, in the same way that a spoon will technically dig a tunnel.

So you do what any self-respecting hacker would do. You read the code. You rewrite it. Your new probe only scans common ports - done in seconds. Your new cracker reads the admin's own password hints from the filesystem - in on the first try. Nobody told you to do this. You just got tired of being bad at it.

That's Blackdoor. You write code. The code hacks servers. Better code hacks them faster, quieter, and before the trace catches up.
