A hacker known as “BobDaHacker” has launched a series of cyberattacks on McDonald’s to highlight vulnerabilities in the fast-food giant’s security systems.
Frustrated by the company’s lack of response, Bob escalated his efforts, ultimately replacing McDonald’s homepage with an image of Shrek — an audacious move that finally caught public attention.
The saga began when Bob discovered an exploit allowing unlimited nugget orders through McDonald’s app. Unable to contact the company’s security team, he took his efforts further, breaching the internal network of McDonald’s Feel-Good Design Hub. This breach granted him the ability to place free orders and manipulate marketing materials, yet McDonald’s remained unresponsive despite his attempts to report the issues via spam reports through the app.
Determined to force action, Bob replaced the McDonald’s website’s main page with a Shrek-themed graphic on August 23, 2025. The stunt went viral, prompting the company to acknowledge the breach and begin addressing the vulnerabilities. McDonald’s has since confirmed it is investigating, though no official statement has detailed the extent of the damage.

This isn’t the first time McDonald’s security has been compromised. Previously, cybersecurity experts uncovered a flaw in the company’s resume processing system, where a simple password — “123456” — exposed the personal data of millions of job applicants. The repeated incidents underscore ongoing weaknesses in the corporation’s digital infrastructure.
BobDaHacker’s unconventional “Shrekburger” campaign has sparked debate about corporate responsibility in cybersecurity. While his methods were illegal, they’ve shed light on the need for stronger protections, leaving McDonald’s to rebuild trust and tighten its defenses in the wake of this high-profile hack.
