Security News > 2024 > April > Frontier Communications shuts down systems after cyberattack
American telecom provider Frontier Communications is restoring systems after a cybercrime group breached some of its IT systems in a recent cyberattack.
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 its systems to prevent the threat actors from laterally moving through the network, which also led to some operational disruptions.
"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.
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.
"The Company continues to investigate the incident, has engaged cybersecurity experts, and has notified law enforcement authorities," Frontier added in the SEC filing.
