Trying to understand Unexpected Ether attack, taken from Mastering Ethereum by Andreas Antonopoulos.
EtherGame.sol is the vulnerable contract and Attack.sol is the malicious contract.
Using Ganache for local blockchain and Truffle for testing.
To spin up a local blockchain use npx ganache-cli --deterministic
Deploy the contracts to local blockchain with npx ganache-cli --deterministic
scripts/index.js performs the attack by interacting with both contracts, to run the script run npx truffle exec --network development ./scripts/index.js
