Panera Bread breach affected 5.1 Million accounts, HIBP Confirms

Panera Bread disclosed a data breach in which attackers (claiming to be the ShinyHunters group) leaked an archive containing customer contact information; Have I Been Pwned and BleepingComputer corroborated that roughly 5.1 million unique accounts were impacted (less than earlier 14M claims). The group alleges access via a Microsoft Entra SSO code tied to a broader vishing campaign targeting SSO at many organizations; Panera says the exposed data was contact information and has notified authorities.
