Practical Fuzzing: A Hands-On Learning Experience for Uncovering Vulnerabilities on Linux
Trainer(s) bio:
Hardik Shah (@hardik05) is an experienced cyber security professional with 17+ years of experience in the computer security industry. Currently works as a Principal Security Researcher at Vehere where he is responsible for analysing latest threats, detecting them and product improvements. In
the past he has worked with various security companies like Sophos, McAfee, and Symantec, where he has built research teams from ground zero, managed various critical cyber threats to provide protection to customers, implemented various product features and has mentored many people.
Hardik is also known for his skills in fuzzing and vulnerability discovery and analysis. He has discovered 35+ vulnerabilities in Microsoft and various open source software. He had conducted Trainings and workshops at various industry leading cyber security conferences such as Defcon, Bsides, RSA dark arts, and many others.
Hardik enjoys analysing latest threats and figuring out ways to protect customers from them.

Training information:
Fuzzing is a powerful technique for identifying vulnerabilities in software. This hands-on training will cover the theory and practical aspects of fuzzing, including coverage-guided fuzzing, basic blocks and binary instrumentation, corpus collection and minimization, target selection, crash triage and root cause analysis, and real-life CVE analysis. Attendees will have the opportunity to practice fuzzing on windows and Linux and apply the concepts and techniques learned in the training to fuzz real world software. This training is suitable for attendees with a basic understanding of software development and testing.
This training will start from user mode fuzzing and later on covers topics like linux kernel fuzzing, crash triage, root cause analysis and firmware fuzzing etc.
Previous Trainings:
TyphoonCon23 - 3days training
Also conducted workshops at - Defcon30, Bsides delhi 2021, Bsides Munich 2021, Greyhat 2021, RSA Dark Arts Village 2022 etc.
