Oh Compiler, You so Crazy...
For Hack Night, Nitin and I set about teaching students how to read and write x86 assembly. I was tasked with teaching students how to write x86. Naturally, being short on time I decided to cheat by writing some C code, compiling it, and taking a peek at the output before walking students through how to manually compile code by hand. When I compiled my demos, there was one particular control flow structure that threw me for a loop (no pun intended.) It was a particular kind of switch; I’d describe it to you but I may as well just share the code.
You Can't Stop The Ropasaurus Rex PlaidCTF 2013
This past weekend, April 19th 2013 in the year of our lord, Brooklynt Overflow assembled to partake in the spectacle of pwning known as PlaidCTF. I’m particularly fond of PlaidCTF because it is the first CTF that I played in as a member of Brooklynt Overflow so many years ago and is usually on or around my birthday. Anyway, enough about me and onto the pwnage. Late in the first day I set my eyes on the RopasaurusRex pwnable for 200 points. RopasaursRex is a very simple binary with two functions.
