Blockchain Security Quick Start 1. Download and decompile contracts (source or bytecode) 2. Map storage layout and identify privileged operations 3. Check for delegatecall, CREATE address prediction, reentrancy, access control 4. Deploy exploit contracts via web3.py or cast/forge 5. Verify win condition (isSolved/flag endpoint) Blockchain CTF Challenge Pattern Key Attack Vectors 1. Delegatecall Storage Manipulation When contract A does to contract B, B's code runs with A's storage. - Deploy exploit contract that mirrors A's storage layout - Exploit contract writes to A's storage slots via del…
