Summary
At this point, I discovered that this server was hacked beyond repair. It needed to completely wiped, and both my client and the administrator knew it. However, being the curious sort, I wanted to do some research on the methods and tricks used to take over this server while it was still up. It was during this research that the Web server stopped responding to commands and the back door ceased to function. For now, this is where I leave you.
In Part II of this story, we will be looking at the methods I used to regain control of the server and how these efforts led me down a path to DOOM (quite literally). DDoS IRC bots, over 2,000 owned computers, and more await you in the FiNaL S3c7i0n.
