Charter Communications Data Breach Could Impact Nearly 5 Million
The ShinyHunters extortion group leaked over 42 million records allegedly stolen from Charter Communications in April 2026. Although the data includes over 42 million records, analysis indicates about 4. 9 million unique individuals may be affected, with exposed information including names, email addresses, phone numbers, and addresses. Approximately 85,000 employee records with job titles were also part of the leak. Charter Communications stated that only sales tools used for managing business customers were impacted and that no customer proprietary network information (CPNI) or sensitive personal information was released. The company is following security protocols and cooperating with authorities. The breach is linked to ShinyHunters' known tactics involving voice phishing and rapid data exfiltration. No evidence of ransom payment was reported, as the data was publicly leaked on a Tor-based site.
