Special thanks to strikeskids for testing this problem and to zaratec for providing some of the assets.
Note that this problem was split into two different problem listings in the problem dashboard, "Shipmate" and "Hoaxer".
This challenge can be played at its new long-term home.

Upload Data (70 points). When Blue's body is found in the communications room, Brown thinks the file she was processing may contain a hint about who killed her. (Misc. Hint: take a look at FileTransferController.ts.)
Process Sample (70 points). After Orange is found dead in the cafeteria, Brown and Cyan investigate soil samples to determine a cause of death. (Crypto.)
Provide Credentials (70 points). Green starts teleporting wildly around The Shelld before suddenly disappearing. Meanwhile, Brown inspects the access logs on the ship's computer to piece together a timeline of the murders. (Web.)

Almost all of the code is part of the handout; to get a copy of what the competitors had, run make handout. Note that the pcap generator is nondeterministic, and I specifically chose a pcap that could be used to reconstruct enough of the image to clearly read the flag for the actual deployment.
TODO: make a writeup
You can see my solution scripts for the Shipmate challenges in the solution directory. I don't have scripts for the Hoaxer challenges since it was relatively easy to live-modify the client code to solve them.
