If you or your children have used McGraw Hill (mheducation.com) platforms, it’s time to update your security settings.
A significant data breach has been confirmed following a Salesforce misconfiguration. This incident has led to the public exposure of over 100GB of data, affecting millions of users.
The Details:
Discovery Date: April 16, 2026
Date of Breach: 10/04/2026
Total Impact: 13.5 million unique email addresses
What was exposed: Names, email addresses, phone numbers, and physical addresses.

What you should do now:
Change your password for McGraw Hill and any other site where you use the same credentials.

Be on high alert for suspicious emails or texts breached phone numbers often lead to a spike in "smishing" (SMS phishing) attempts.
