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.
“We are aware of the post and following our security protocol in response. The initial evidence suggests that one of our third-party vendors had a security breach,” a spokesperson said. “At this time, we do not believe that any customer proprietary network information or customer financial data was included.”
The spokesperson did not respond to follow-up questions about what third-party vendor was hacked, when the hack occurred or when affected customers will be notified.
The breach comes just two weeks after the Federal Communications Commission voted unanimously to investigate potential changes to the breach notification rules for telecommunications companies.
