User Struct corruption: Because each user struct is Encrypted and Signed with Keys deterministically created based on the user’s username and password, each user is stored in the Data Store with Integrity and Authenticity. If an attacker somehow gained access to the Data Store and and tampered with a User Struct, upon calling GetUser()

Project 3. Getting Started. Your task is to find eight vulnerabilities in the UnicornBox servers. When you successfully execute an exploit, the status entry on your scoreboard will change from 0 to a timestamp, to indicate that you have received a flag. Your goal is to collect all eight flags.CS 161: Computer SecurityQuestion 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.
