Improvements of fuzzing techniques in Vuzzer
Hi, this is my report of my academic internship at the University of Bristol’s Cyber security group. This Cyber security group works on many projects to protect computer systems. One of them is Vuzzer, a program that tries to discover vulnerabilities independently within applications. This project helped the cyber security community, but there is still a lot of features that could be added to make it more powerful. It’s in this context that I was charged to improve the existing software, in order to make it more effective. My report shows the results of my contribution.
