Native DLL functions from Java code
Here is a tiny note on how to invoke native exported DLL functions from Java code in Windows.
According to the Wiki: "Java Native Access (JNA) provides Java programs easy access to native shared libraries without using the Java Native Interface. JNA's design aims to provide native access in a natural way with a minimum of effort. Noboilerplate or generated glue code is required."
I wrote a DLL in FASM to make it more fun.

I took part in PoliCTF 2012 and right now I'd like to make some notes how to solve challenges from this competition. All challenges in this CTF were divided in four groups: Crypto, Bin-Pwn, GrabBag and Forensics. 100, 200, 300, 400 and 500 points challenges in each division. This post is the first one and about all BIN-PWN challenges.
