Finally, the robots managed to sneak into one of our breweries. I guess I won't have to explain how bad that really is. That darn non-physical ones even shutdown our login system. Shiny thing, advanced technology, all based on fingerprints. Been secure as hell. If only it was running. Well, basically, we're screwed.
But wait, there's hope. Seems like they didn't shutdown our old login system. Backward compatibility's a bitch, eh? Unfortunately, we got like _zero_ knowledge about the protocol. I mean come on, the last time we used that thingy was like decades ago. If we are lucky, the old authentication method is buggy.
So, I heard you're kinda smart? Have a look at it. We desperately need to get drunk^W supply. You'll find the old system at ctf.fluxfingers.net:1335. Good luck.
