About This Breach
In May 2026, Charter Communications, the American telecommunications company operating the Spectrum brand of internet, cable, and mobile services, was affected by a data breach as part of the ShinyHunters extortion campaign targeting Salesforce environments. The breach exposed approximately 4.85 million unique email addresses along with first and last names, phone numbers, physical addresses, job titles, and internal Salesforce CRM records belonging to both customers and employees. The data was exported from Charter/Spectrum Salesforce objects (business, customer-service, and enterprise contacts, leads, accounts, support cases, and service requests) as well as internal user and employee directories. No passwords were included. The records were distributed via Telegram after Charter declined to pay a ransom to the threat actor group ShinyHunters.
