He left a pause of two days so as not to be too obvious, and then made a call to the network operations center (NOC) at the company. He claimed he was trouble-shooting a problem for Tom, the target, and asked to have Tom's network connection disabled. Bobby knew this was the trickiest part of the whole escapade—in many companies, the help desk people work closely with the NOC; in fact, he knew the help desk is often part of the IT organization. But the indifferent NOC guy he spoke with treated the call as routine, didn't ask for the name of the help desk person who was supposedly working on the networking problem, and agreed to disable the target's network port. When done, Tom would be totally isolated from the company's intranet, unable to retrieve files from the server, exchange files with his coworkers, download his email, or even send a page of data to the printer. In today's world, that's like living in a cave.
