I Hacked Half of America's Fast Food Chains (and Got Away with It)
A white hat hacker found a vulnerability in order management systems, allowing menu and price manipulation.

White hat hacker mrbruh recounted how he gained access to order management systems of several major fast food chains. Using a common order-taking platform, he could change prices, add items, and even disable individual restaurants.
How It Worked
The vulnerability was due to insufficient authentication in the API used by dozens of chains. The hacker only needed the restaurant's ID to send commands as an admin. He demonstrated changing a burger's price to $0.01 or completely locking the kitchen.
Business Implications:
- Financial losses from price manipulation
- Reputational damage from disabling restaurants
- Risk of customer data leaks
The hacker claims he caused no real harm and alerted companies to the flaw. However, the incident raises a crucial question: how secure are the systems that thousands of outlets depend on?
Comment from METABYTE studio: This case reminds us that even everyday services can have critical security holes. When developing digital products for restaurants and retail, we always prioritize API auditing and protection against unauthorized access.
