The workshop students started off playing an activity where they rolled a die and answered a question based on the number they received. Afterwards, Rachel got a message from Matt saying that he felt guilty for eating the cookies. However, when he was questioned, he told the class that he never sent it. Jenny and Alexandra brought Neal and Mike, the system administrators, to examine the message. Neal determined that somebody "spoofed" the e-mail, which means that the person who sent it used Matt's e-mail address to send the message. To figure out how spoofing works, they used a program called Terminal, the command line interface for Mac computers.
The students learned how to create and manipulate files in Terminal. Neal also taught the class how to find their IP Address, a set of numbers unique to each computer, using a command called ipconfig. Mike explained ssh, or secure shell, that allows each person to log in to the Shodor server.
After a lot of searching for evidence, the class found out that Trey was the only person online who could have sent the message. Jenny and the students obtained a piece of paper with his handwriting and got a fingerprint as evidence. They created a mock trial with Alexandra as the prosecution, Rachel as the defense, and Jenny as the judge. The jury consisted of the interns in the office. In the end, the jury found Trey guilty, and sentenced him to observing everybody else eating cookies.
