  • assign5 Released! Fri July 30 by Andrew Assignment 5 has been posted in the assignments dropdown. It is meant to reinforce the topics of assembly translation, reverse engineering, and trust and privacy. The backstory: you have been hired as a security expert for Stanford Bank (a fictional on-campus bank). They need you to investigate reports of infiltration and security issues and replicate the issues so that they can fix them. There are three parts to this assignment, and each one will have you investigate supposed vulnerabilities and assess the risks the bank faces. These problems are like C/assembly "puzzles" to solve, and we hope you enjoy solving them and exploring this material as much as we enjoyed creating them! The assignment is due Fri 8/13 at 11:59PM PT. You can find more details on the assignment page.

    We encourage you to come to Assignment Handout Helper Hours (AHH Hours) to understand the assignment better - it'll be at 1pm PT on Tuesday, with the Zoom link on Canvas.

    As you start working, we want to include a reminder about the course style guide; it contains an in-depth reference about how to ensure your programs have great style! We have also added a new codecheck tool to this assignment - check out the spec for more information. Additionally, through TA helper hours and the discussion forum, our focus will be on supporting you so that you can track down your own bugs. Please ask us how to best use tools (like the brand-new GDB!), what strategies to consider, and advice about how to improve your debugging process or track down your bug. If you have debugging questions during helper hours, please make sure to gather information and explore the issue on your own first, and fill out the QueueStatus questions with this information. Starting with a future assignment, we will require this information when signing up for helper hours for debugging help, so please make sure to provide as much information as possible.
