Solving OpenZeppelin's Ethernaut CTF - Force
Post #8 of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. All contracts have a hidden self-destruct button. Did you known that? Read on, and see it for yourself.

Post #7 of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. In Delegation, we study how to exploit a trustful contract that uses a not-so-safe low-level call.
Fourth post of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. Through solving Coinflip, we learn how to exploit a common case of a poorly implemented PRNG in the Ethereum blockchain.
Fifth post of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. We claim ownership of the Telephone contract by first understanding the difference between the sender and origin of Ethereum transactions.
Sixth post of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. In Token, we hack a basic token contract and manage our way to earn a huge amount of ethers.
Third post of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. In this one, we solve the second challenge: Fallout.
Second post of a series in which we tackle the challenges in the Ethernaut CTF by OpenZeppelin. In this article, after explaining the Solidity and Web3 basics by examples, we solve the first challenge: Fallback.
First post of a series in which we will tackle the challenges in the Ethernaut CTF by OpenZeppelin. In this first article, we prepare the environment with Truffle and Ganache-cli.
