I hacked Magic the Gathering: Arena for a 100% win rate (mayer.cool)

Article summary

The article describes how the author hacked Magic: The Gathering Arena to achieve a 100% win rate by exploiting a vulnerability in the game's client-side code. The author discovered that the game's bot logic runs locally on the player's machine, allowing them to create a headless client that can connect to the game server and concede on behalf of the opponent. The vulnerability was patched by the game's developers after the author disclosed it to them. The article provides a detailed explanation of the hack and the author's thought process behind it.

What commenters say

• The game's developers should have validated user inputs to prevent such exploits.
• The hack was possible due to the game's architecture, which allows for client-side bot logic.
• The vulnerability was not surprising given the complexity of the game and the potential for security oversights.
• The game's developers responded promptly to the disclosure and patched the vulnerability.
• The hack highlights the importance of server-side validation and security measures.
• The article's explanation of the hack was clear and educational, making it accessible to non-technical readers.
• The game's design allows for disconnection timeouts to be fairly long, which contributed to the exploit.
• The exploit was not necessarily a result of poor security, but rather a consequence of the game's complexity and design choices.
