Video games are some of the most heavily attacked software systems in existence. They combine real-time networking, virtual economies, identity, and competitive integrity, which makes them a perfect proving ground for modern cyber attacks. The same techniques used to create aimbots, infinite money glitches, and item duplication exploits are the same techniques used to break cloud APIs, SaaS platforms, and mobile apps.

Using a simple multiplayer game and its backend services, we’ll demonstrate how attackers:

- Manipulate client state
- Forge and replay network traffic
- Exploit race conditions
- Abuse predictable identifiers and naive economic rules

Each exploit is mapped directly to a real-world security failure (API abuse, business-logic flaws, and zero-trust violations), showing how “trusting the client” and weak server-side validation collapse as soon as an attacker starts observing and modifying runtime behavior.

You’ll leave with a practical threat model for any interactive system, and a new way to spot how ordinary features become an exploit playground under adversarial thinking.
