ShinyHunters published data allegedly stolen from Charter Communications after a failed ransom demand, exposing approximately 4.9 million unique customer email addresses and associated names, phone numbers, and addresses (with a larger 42M-record claim). Charter confirmed the incident, activated security procedures, and said no sensitive personal information or CPNI was exfiltrated; the report also links ShinyHunters to a pattern of extortion-driven data leaks and notes their frequent use of social engineering and credential theft against SaaS platforms.
