The PowerPoint slides at [255] describe a security class project where students successfully hacked the Boston subway system.

a. Summarize each of the various attacks. What was the crucial vulnerability that enabled each attack to succeed?

b. The students planned to give a presentation at the self-proclaimed "hacker's convention," Defcon 16 [80], where they would have presented the PowerPoint slides now available at [255]. At the request of the Boston transit authority, a judge issued a temporary restraining order (since lifted) that prevented the students from talking about their work. Do you think this was justified, based on the material in the slides?

c. What are war dialing and war driving? What is war carting?

d. Comment on the production quality of the "melodramatic video about the warcart" (a link to the video can be found at [16]).
