CSAW CTF Finals 2013 VMs
After reading through the Mandiant APT1 report detailing the presence of the Advanced Persistent Threat group 1 (APT1) which has been attacking a devastating number of companies and governments around the world a variety of questions come to mind. Considering the amount of time that has passed since Mandiant published the APT1 report in February one cannot help but wonder what the current status of APT1 is. As a quick overview for those who didn’t finish the report, Mandiant leaves us with two very profound statements regarding the composition of the APT1 group.
July 5-7 Brooklynt Overflow participated in SIGINT CTF hosted by the good folks over at CCCAC in Germany. Despite the fact that Brooklynt Overflow is not always the most effective team during the summer owing to inability to gather in the same place and the fact this competition was over a holiday weekend (Go team USA!) we didn’t fare terribly, finishing #21 on the scoreboard. This is a write up of one of the pwning challenges, crash.

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.
