Frontier warns 750,000 of a data breach after extortion threats

Frontier Communications is warning 750,000 customers that their information was exposed in a data breach after an April cyberattack claimed by the RansomHub ransomware operation.

“On April 14, 2024, we detected unauthorized access to some of our internal IT systems,” reads the data breach notification sent to impacted customers.

These data breach notifications come after the RansomHub extortion group claimed responsibility earlier this week for the attack on Frontier.

On Tuesday, June 4, RansomHub added Frontier Communications to its extortion portal on the dark web, threatening to leak 5GB of data allegedly stolen during the attack, containing the information of 2 million customers.

The threat actors have given Frontier until June 14 to respond to their demands, or they will sell the data to a single buyer, the highest bidder.

Christie’s confirms breach after RansomHub threatens to leak data.
