Blue Shield’s Data Breach: A Comedy of Errors Exposing 4.7 Million Health Records to Google Ads
Blue Shield of California accidentally shared 4.7 million members’ protected health information with Google Ads, thanks to a minor website misconfiguration. Although Google’s ads might have been a little too personalized, rest assured, no bad actors were involved. Just think of it as a very awkward, extended digital handshake.

Hot Take:
Looks like Blue Shield of California played a little too fast and loose with their Google Analytics settings, and now 4.7 million people’s health data might be just one targeted ad away from a “whoopsie daisy” moment. Maybe next time they’ll double-check their tech stack isn’t acting like an over-sharing teenager on social media!
