I am Chris Higgins
Application Developer, Server Administrator, Masters Student, Security Enthusiast
I am an application developer and server administrator for the College of Arts and Sciences at Illinois State University, as well as a Masters student studying IT security and networking. Currently I’m interested in VoIP technologies and security, reverse engineering, exploit development, and secure web programming.
You can follow me on Twitter @ch1gg1ns, on GitHub, or you can find me on FreeNode as chiggins usually lurking in #isusec or #vulnhub.
Lately I’ve been wanting to explore some of what I call the “black magic” of infosec, reverse engineering and shellcoding. Whenever I see some posting or article that comes out on this I always become curious and bewildered at what I’m looking at because I just don’t understand it. On Twitter I’ve been seeing @SecurityTube advertise their x86_64 Assembly and Shellcoding on Linux video course, so I decided to drop some money and learn what I can from it. I’ve yet to fully finish it, but more on that later.

Well, this is embarrassing. A few weeks ago I decided to change things up a bit on my server, move from Ubuntu to Arch Linux, reconfigure a few things and do some clean-up. Well, apparently past Chris decided it would be a grand idea to forget to copy over my back-up files to a disk that wasn’t about to be blown away… How awakward.
I thought to use photorec and try to recover my missing data. The only data I really cared about was my old Wordpress blog database, and the custom theme I made. But I decided it might just be better to start anew. In a short Twitter exchange, WiK (@jamiefilson) suggested I take a look at Octopress. After delving into the Octopress documentation, I decided to give it a go. Now I’m using Octopress and Github Pages for this blog, and hopefully I’ll actually pay more attention to actually putting up some content.
So here I am. I’ll get around to putting up more posts and create a theme of my own in the next coming weeks. I guess we’ll see what happens!
The BSides Chicago 2013 CTF was a fun one and quite the learning experience, so here’s my first ever write up and it’s going to be on challenge #31, easy reverse engineering on a .NET console application.

So this past weekend I was in Chicago for Thotcon 0×4 and BSides Chicago 2013. Quite fun stuff since I haven’t been to a con since Derbycon. I was really looking forward to catching up with some people, checking out some talks, and participating in the CTF at BSides.

A few weeks ago I ran into an article on how to use Google Cloud Messaging with the .NET Framework. That got me thinking, and I wanted to give it a shot in PHP, it couldn’t be too bad right? So, here’s just some simple code on crafting the POST request to send to a specified Android device. All you need to do is supply your own various IDs from Google and whatever Android device you want to send to (as long as it’s registered) and you’re all set. Take a look at my code:
