American steel giant Nucor Corporation (NYSE: NUE) has shared an update on the recent cyberattack, confirming that hackers have taken some data from its systems.
Nucor, which claims to be the largest steel manufacturer and recycler in North America, disclosed the cybersecurity incident in mid-May.
The attack involved unauthorized access to IT systems and resulted in some systems being taken offline and the temporary halting of certain production operations.
Nucor on Friday shared an update on the incident in a filing with the Securities and Exchange Commission (SEC). The company’s investigation showed that the threat actor managed to exfiltrate “limited data” from the compromised IT systems.
“The Company is reviewing and evaluating the impacted data and will carry out any appropriate notifications to potentially affected parties and to regulatory agencies as required by applicable law,” Nucor said.
Systems taken offline in response to the cyberattack have been restored and the company told the SEC that the incident is unlikely to have a material impact on its financial condition or results of operations.
Nucor believes the threat actor has been locked out of its systems and it has taken steps to prevent future breaches.
While its response to the incident suggests that the steelmaker may have been targeted in a ransomware attack, no known group appears to have taken credit for the Nucor hack.
