Charter Communications, one of the largest US broadband providers, has confirmed a data breach after the ShinyHunters extortion group claimed to have stolen 40 million customer records via a vishing attack compromising a Microsoft Entra account. The threat actors accessed Charter's Salesforce instance and are demanding ransom to prevent data publication. Charter disputes the sensitivity of exfiltrated data, but the threat actor claims CPNI and customer support data were included.

Impact verdict

Medium impact. Charter Communications is one of the largest US broadband providers with tens of millions of customers; a confirmed breach of this scale creates plausible cyber liability and data breach notification cost exposure relevant to cyber insurance books. Loss pathway: cyber liability and data breach coverage for a named major US telecom. Evidence: Charter confirmed the breach; ShinyHunters claims 40 million records stolen including potential CPNI data, triggering regulatory notification obligations. Limit: Charter disputes sensitivity of exfiltrated data and no ransom payment or regulatory enforcement action is yet confirmed, limiting current loss visibility.
