If you've ever had an account or relationship with Grubhub, it's worth checking whether your personal data was exposed in this incident. Here's what happened, what data was involved, and what to do about it.
What Happened
Grubhub disclosed a data breach in 2024 that it attributed to unauthorized access through the compromised account of a third-party service provider it worked with, rather than a direct breach of Grubhub's own core systems. The incident affected customers, including a significant number using Grubhub for campus dining services.
What Data Was Exposed
The exposed data included names, email addresses, phone numbers, and for a limited number of users, partial payment card information. Grubhub stated that full card numbers and passwords were not compromised, as full card data is not stored directly on Grubhub's own systems.
Why This Still Matters
Exposed data doesn't expire. It's sold, traded, and reused for years, fueling credential stuffing attacks — automated attempts to reuse your email and password combination across other sites. If you reused a password anywhere, one old exposure can compromise several current accounts.
