The ShinyHunters extortion gang stole personal information from 4.9 million accounts after hacking the U.S. telecom giant Charter Communications in early April, according to data breach notification service Have I Been Pwned.
Charter has over 92,000 employees and provides internet, mobile, video, and voice services to more than 32 million customers and over 57 million homes in 41 states across the U.S. through its Spectrum brand.
The company confirmed the breach earlier this week, saying that the attackers did not steal sensitive personal customer information and that it had alerted authorities about the incident.
"No sensitive personal information (PI) or customer proprietary network information (CPNI) data was exfiltrated by the threat actor as a result of recent activity," Charter told BleepingComputer.
While Charter has yet to attribute the attack and has not shared further details, the ShinyHunters extortion gang claimed responsibility and told BleepingComputer that they breached the company's systems on April 1 in a voice phishing (vishing) attack that compromised an employee's Microsoft Entra account.
