[There was a special prize for the first team to complete this round, which has now been claimed. Solving this round is still useful for solving the overall puzzlehunt!]
Cats are well known to be masters of stealth and infiltration.... and when these hacker cats cross your PATH, they may place a hex on you!
Phil Karlton remarked:
There are only two hard things in Computer Science: cache invalidation and naming things.
... well, the naming of cats is traditionally a hard problem (it isn't just one of your everyday games!). Maybe the first hard thing was actually supposed to be "cat invalidation"? (That would no doubt be a real challenge because of cats' deep-seated validity.)
The hacker cats' ringleader was spotted recently ... or maybe she was striped ... actually, nobody's quite sure what she looks like! Can you track down the ringleader's heavily-encrypted name?
All of the challenges in this round, except the ringleader's name itself, solve to unsigned 32-bit integers; however you identify them, make sure to express them in hexadecimal when entering the answers. (As with other CTF events, please do not attack the event infrastructure.)
This calculator can be used to XOR your answers together to decrypt the hacker cat leader's name and display it on the display. (Using XOR, the order of the answers doesn't matter at all, but you'll need all six answers to get meaningful output. In the current version of the software, answers are not inserted into the calculator automatically as you find them; you'll have to type them in yourself to make use of the calculator.)
