Solidity Smart Contract Attack Methodology
Last modified: 2023-09-30
When attacking target contract, we can create an attack contract which loads the target contract and abuse it.
Create an Attack Contract
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
// Define interface for victim contract
interface IVictim {
// Set the Victim contract functions
function example1() external;
function example2(uint) external;
}
// Define Attack contract to compromise the victim contract
contract Attack {
IVictim public victim;
constructor(address _victimAddress) {
// Initialize Victim contract (interface)
victim = IVictim(_victimAddress);
}
// Create a function to be used for attacking the victim contract
function attack() public {
victim.example1();
victim.example2(1);
}
}
