Nucor Corporation, the leading steel manufacturer in North America, has confirmed that hackers successfully stole sensitive data during a recent cyberattack on its systems. The breach marks a significant security incident for the industrial giant, which operates mills across the U.S., Canada, and Mexico with over 32,000 employees and annual revenues exceeding $30 billion.
The company first disclosed the cybersecurity event last month, revealing it had temporarily shut down certain systems to contain the breach. This precautionary measure led to production halts at multiple facilities. Nucor engaged law enforcement and cybersecurity specialists to investigate the incident and restore operations.
In a recent SEC filing, the steel producer confirmed that attackers had exfiltrated limited data from its IT infrastructure. While the exact nature of the stolen information remains unclear, Nucor stated it is assessing the scope of the breach and will notify affected parties if necessary. The company emphasized that compromised systems have since been restored and that the threat actors no longer have network access.
Nucor’s statement explained, “The cybersecurity incident temporarily restricted access to certain IT applications, impacting operations at select facilities. Out of caution, we proactively paused production at several locations.” The filing also noted that the investigation revealed data theft, though specifics about the attack vector or discovery timeline were not disclosed.
So far, no ransomware group has publicly claimed responsibility for the breach. However, many cybercriminal operations now employ double-extortion tactics, stealing data before encrypting systems to pressure victims into paying ransoms. Whether Nucor faced encryption demands remains unknown.
Requests for additional details from the company have gone unanswered, leaving questions about the attack’s full impact unresolved. As one of the largest players in the steel industry, Nucor’s breach highlights growing cybersecurity risks facing critical manufacturing sectors.
