Frontier Communications revealed that information from more than 750,000 customers — including full names and Social Security numbers — was exposed in a data breach following a cyberattack on April 14. The hackers claim to have even more and will release it unless Frontier pays a ransom.
The attack allowed hackers to access personal data of 751,895 customers on Frontier’s systems, according to a sample Frontier notice submitted to the Maine Attorney General’s Office. Border has impacted customers notified and provided them with a year of free credit monitoring and identity theft services, but says it “does not believe” customers’ financial information was exposed in the breach.
Computer beeping reports that the RansomHub extortion group claimed responsibility for the attack on June 4th and is threatening to leak the 5GB of customer data it allegedly stole unless Frontier responds to its demands by June 14th. The group claims the stolen dataset contains information belonging to two million Frontier customers, including full name, physical address, date of birth, social security number, email address, credit score and phone number.
Frontier says it strengthened its network security following the attack and notified regulatory authorities and law enforcement. A securities archiving reveals that the company was forced to shut down some of its systems to contain the incident.
