Block Buster - Blockchain Security CTF
A criminal syndicate has stored evidence on the blockchain, thinking it's secure. In Challenge 1 "The Locked Vault", they locked evidence in a vault contract using private variables, believing blockchain privacy would protect them. In Challenge 2 "Chain Breaker", they implemented a token system with arithmetic flaws to guard critical information. Your mission is to exploit blockchain transparency and smart contract vulnerabilities to retrieve the hidden evidence and bring the criminals to justice.
