Cs161 project 3
Each group must submit writeup–two pages maximum, please. For each of flags 3–8 only, include a brief description (2–3 sentences) of how you acquired the flag, and a suggestion (a line of code or 2–3 sentences) for how to protect against your exploit. Grading & Deliverables . 70 points for finding exploits (8.75 points for each flag). Leak some secret configuration variables. Difficulty: Medium. UnicornBox stores some configuration variables in a config.yml file in a folder separate from the users’ files: The layout of the server storage is as follows: site/ files/ foo1.txt foo2.txt ... config/ config.yml. Your task: Gain access to the secrets stored within config.yml.

Announcements: The instructors and TAs will periodically post announcements, clarifications, etc. to the Piazza site. Hence it is important that you check it reguarly throughout the semester. Prerequisites: The prerequisites for CS 161 are CS 61B, CS61C, and CS70. We assume basic knowledge of Java, C, and Python.CS 161 Computer Security . Project 3. Due: April 20, 2018, 11:59PM.

In this project, you will apply the cryptographic primitives introduced in class to design and implement the client application for a secure file sharing system. Imagine something similar to Dropbox, but secured with cryptography so that the server cannot view or tamper with your data.An End-to-End Encrypted File Sharing System. In this project, you will apply the cryptographic primitives introduced in class to design and implement the client application for a secure file sharing system. Imagine something similar to Dropbox, but secured with cryptography so that the server cannot view or tamper with your data. Make sure you really understand what’s going on behind the scenes. For example, for project 3 in 161, initializing the min and max variables to the users first value choice is critical for that project, make sure you understand that process and why that is so important. The rest will come with time and practice.Welcome to CS 161 Project 3. In order to get started, log in with your CalNet Account. Welcome to CS 161 Project 3.

Welcome to CS161! We've got an exciting quarter ahead of us filled with beautiful algorithms and problem-solving strategies. Over the upcoming weeks, we'll explore a variety of ways to model and solve problems that arise in computer science, biology, operations research, networking, and much more.The cs161 user is using UnicornBox to store a le called ip.txt. cs161 is a special-purpose account on UnicornBox. It uses a separate login mechanism, so you won’t be able to log in as cs161, but you may still be able to change some of its les. Your task: Change the contents of cs161 user’s ip.txt le to be 161.161.161.161. Double check that you are using Python3---on many machines (including Hive), the python command defaults to Python 2.

The vulnerability lies in the fact that the canary value can be found through the printf statement in dehexify.Specifically, the while loop in dehexify will automatically increment i by 3 if it encounters the '\\' and 'x' next to one another.

The backend for this project exclusively uses single quotes for SQL queries. It is possible to select constants in SQL rather than selecting column names. For example, SELECT 1, 'foo', 'evan' will return a single row with 3 columns, with values of 1, 'foo' and 'evan'.Question 3: Polaris Main Idea: In order to exploit the vulnerability of the Polaris satellite, we were required to first leak the stack canary. Once we knew the exact value of the canary, we were able to treat the exploit like a standard buffer overflow problem, with the only difference of resetting the original value of the canary.
