You work as a professional Ethical Hacker. You are assigned a project to perform blackhat testing on www.we-are-secure.com. You visit the office of we-are-secure.com as an air-condition mechanic. You claim that someone from the office called you saying that there is some fault in the air-conditioner of the server room. After some inquiries/arguments, the Security Administrator allows you to repair the air-conditioner of the server room.

Further, you copy the netcat tool on the server and install its startup files to create a reverse tunnel and move a shell to a remote server whenever the server is restarted. You simply restart the server, pull out the Knoppix Live CD from the server, and inform that the air-conditioner is working properly.
