Telecommunications company Charter Communications said one of its third-party vendors suffered from a security breach after data from the company showed up on a hacking forum.
On Thursday, a forum user posted information allegedly stolen from the company that included names, account numbers, addresses and more for about 550,000 customers. Charter Communications is the second largest cable operator in the U.S. and fifth largest telephone provider – with more than 32 million customers in 41 states.
