Jeffery works at a large financial firm in Dallas, Texas as a securities analyst. Last week, the IT department of his company installed a wireless network throughout the building. The problem is, is that they are only going to make it available to upper management and the IT department.

Most employees don’t have a problem with this since they have no need for wireless networking, but Jeffery would really like to use wireless since he has a personal laptop that he works from as much as he can. Jeffery asks the IT manager if he could be allowed to use the wireless network but he is turned down. Jeffery is not satisfied, so he brings his laptop in to work late one night and tries to get access to the network. Jeffery uses the wireless utility on his laptop, but cannot see any wireless networks available. After about an hour of trying to figure it out, Jeffery cannot get on the company’s wireless network. Discouraged, Jeffery leaves the office and goes home.

The next day, Jeffery calls his friend who works with computers. His friend suggests that his IT department might have turned off SSID broadcasting, and that is why he could not see any wireless networks. How would Jeffrey access the wireless network?

A.
Run WEPCrack tool and brute force the SSID hashes

B.
Jam the wireless signal by launching denial of service attack

C.
Sniff the wireless network and capture the SSID that is transmitted over the wire in plaintext

D.
Attempt to connect using wireless device default SSIDs
