I had a list of controllers that we forgot the usernames and passwords to. We knew it was some combination from about a half dozen of each, just not exactly what was what. A few hundred of them so a tedious task for a human to go through and validate them all.
Got flagged for attempting to have Codex write a quick script to basically dictionary attack my own infrastructure with a tiny dictionary file.
A bit silly, but it doesn’t take a whole lot.
