Charter breach warning: What customers should know

A phone call may have opened the door to a major telecom security scare involving Charter Communications, the company behind Spectrum. Charter is one of the largest broadband and cable providers in the United States, serving more than 32 million customers across more than 40 states with internet, cable TV, mobile and phone service.

The company has confirmed a cybersecurity incident after the ransomware group ShinyHunters listed it on a leak site. Charter says the most sensitive customer information was not released.
