Charter Communications (Spectrum) Data Breach Confirmed After ShinyHunters Extortion Threat
Charter Communications, operating as Spectrum, confirmed a data breach on May 26, 2026, following threats from the ShinyHunters extortion group to leak stolen data. The breach, which occurred around April 1, 2026, involved a vishing attack that compromised an employee's Microsoft Entra account, granting access to Salesforce data. While Charter initially stated no sensitive personal information or CPNI was exfiltrated, later breach monitoring indicated the exposed dataset was tied to 4.9 million accounts, including names, email addresses, phone numbers, physical addresses, and job titles. Researchers later reported the leak covered at least 13 million people and nearly 10 million customer-support records.
