$ ./exploit.py TARGETCapture
Land the shell and grab local.txt and proof.txt on your own box, exactly like the exam.
$ cat proof.txtSubmit
Send your working exploit and usage notes. We verify every one by hand before it counts.
$ git push origin pwnFive tiers, one path
Every machine belongs to a tier. Clear one from each to prove you can hold the whole spectrum — from a gentle warm-up to a chain that will test everything you know.
