Offensive Security in Web3 from Exploit Mindset to DeFi Precision Bugs with Josselin Feist

Description

What does security actually look like in Web3? This session explores how offensive security translates into the world of blockchain, including how attackers analyze, test, and exploit smart contracts. From there, we'll examine rounding errors in DeFi, building on the concepts from Josselin's recent article (https://seceureka.com/blog/rounding-in-defi). We will show how seemingly minor implementation details can introduce exploitable financial logic flaws. Follow Josselin on X at: https://x.com/Montyly
