You might remember my first Maximum Overkill writeup, where I made a ROP exploit with ASLR/NX bypass for a simple buffer overflow exercise. I completed another over-the-top, why-would-you-even-do-this exploit for a CTF challenge and figured I’d shared it.

RingZer0Team is hosting a long-term CTF. The shellcoding challenges presented a very nice set of challenges. It was really fun and I learned a ton about 64-bit shellcoding while solving them!

So maybe ‘weekly’ isn’t really the right word for these posts ;]

Within a few days of releasing thePurge, strata decided to release yet another VM! This one was called theFrequency… It presents a very nice challenge involving radio signal encoding and audio stego. I needed several hints to solve this one, but it was worth it!

A bit later and shorter than planned due to the CTF, but here’s another weekly roundup!

Quirky little challenge, this sbox. We’re actually given the keys to the kingdom right away!

mentalnote was a 400 point exploitation-type challenge in NullCon’s HackIM CTF.

mixme was a 400 points exploitation challenge of the NullCon HackIM ctf. We solved it with just 20 minutes on the clock!

Time for another weekly round-up of interesting links!

Man, 31C3 CTF was tough. I managed to get this flag, worth 10 points. Seems I need to keep learning ;] Let’s have a look at cfy.
