Charter Communications has confirmed a data breach after the ShinyHunters extortion group listed the telecommunications provider on its leak site and threatened to publish stolen customer records.
Public reporting indicates the attackers gained initial access through vishing that compromised an employee’s Microsoft Entra ID account, then moved laterally to SaaS applications including Salesforce. The data set offered for sale or extortion contains customer names, email addresses, physical addresses, phone numbers, service plan details, and support ticket information. Charter stated that no sensitive personal customer information or Customer Proprietary Network Information (CPNI) was exfiltrated. The precise number of affected customers remains undisclosed. Industry research from sources such as DoxxScan™ continuous monitoring indicates that telecommunications providers have become frequent targets because subscriber records serve as reliable anchors for subsequent identity-based attacks.
