I have put together a nice little challenge for you guys, and I hope you guys enjoy it, as much as I enjoyed making it.
(Flashes back to spending 4+ hours trying to get a db to take queries case insensitively, when it does that by default #facepalm)
First, you will need to grab a copy of the challenge03.zip file located at:
https://www.dropbox.com/s/rqucsjssl5x64 ... enge03.zip
Next, you of course will need to extract the folder. The folder contains the details for the challenge completion located in the README file, which is:
- Code: Select all

"Hello, I heard that you are an amazing hacker. I myself have some skills in my toolbox, but I hit a road bump today.
I was wondering if you could help me out with this little issue.
Basically, there is a guy who is wanted for murder. They say that he lures people from the internet. The problem is that the FBI can not seem to get a trace on this guy.
So I decided I would see what I could do. I managed ssh into his machine and pull a folder called "meet". I believe this file contains the information somewhere about his
next attack. However, upon opening it, I get presented with a encrypted file named "encrypt.txt". This needs to be decoded. I found where he has been using his encryption
algorithm, it is located at http://missions.securityspot.org/03/manipulate.html
The rest of the information, I have no idea about, there is a file called jpg-gpg, which contains three files (xaa, xab, xac) with no extensions...
Please, if you can help me track this killer so we can put him behind bars, I would much appreciate it.
Thanks in advance,
Some things to note:
The website given should be used only to understand the encryption method. Feel free to look around it, etc if you wish. You will not be able to sign-up, transfer files, recieve files, or login. The logo on the home page contains a link (http://missions.securityspot.org/03/check.html) which will allow you to check if your password is correct.
I hope you all enjoy the challenge!
