U.S. telecom provider Frontier Communications shut down its systems after a cybercrime group breached some of its IT systems in a recent cyberattack. BleepingComputer reports: Frontier is a leading U.S. communications provider that provides gigabit Internet speeds over a fiber-optic network to millions of consumers and businesses across 25 states. After discovering the incident, the company was forced to partially shut down some systems to prevent the threat actors from laterally moving through the network, which also led to some operational disruptions. Despite this, Frontier says the attackers could access some PII data, although it didn’t disclose if it belonged to customers, employees, or both.
“On April 14, 2024, Frontier Communications Parent, Inc. [..] detected that a third party had gained unauthorized access to portions of its information technology environment,” the company revealed in a filing with the U.S. Securities and Exchange Commission on Thursday. “Based on the Company’s investigation, it has determined that the third party was likely a cybercrime group, which gained access to, among other information, personally identifiable information.” Frontier now believes that it has contained the breach, has since restored its core IT systems affected during the incident, and is working on restoring normal business operations.
