Most Web3 incidents aren’t “one bug, one drain” anymore. Attackers increasingly chain weaknesses across layers such as legacy contracts, subtle numerical edge cases, protocol/bridge exit paths, and off-chain vendor exposure, into an exploit path that ends in irreversible loss. In this talk we'll take a look at some high-signal incidents from 2025 and discuss how to break attack chains before they reach funds. Lessons learned will include practical strategies that projects may adopt to build defense-in-depth that breaks attack chains.
