- Nucor confirmed to like a cyberattack
- It was forced to close parts of its operations to contain the incident
- No threat actors assumed the responsibility yet
Nucor, one of the largest steel producers in the United States, was forced to close parts of its operations to tackle a running cyber attack. The company confirmed the news in a new 8-k form that was submitted to the US Securities and Exchange Commission (SEC).
In the filing, Nucor said it recently observed an “unauthorized third party” that gained access to “certain information technology systems.” When it discovered the penetration, it activated its incident response plan, brought in a third -party cyber security company to help and inform relevant law enforcement agencies.
However, it also took “potentially affected systems offline” to implement “other inclusion, remedy or recovery measures”.
Was it ransomware?
Nucor told SEC that it “temporarily and proactively” stopped certain production operations in different places “in an abundance of caution”. It now restarts these operations, it added.
Usually, when a business closes its activities to include a cyberattack, it usually ends up becoming a ransomware attack. While the company did not explicitly say so, the fact that it stopped operations could suggest that this is the case.
Furthermore, the register tried to reach the company’s facilities around the United States, but found many phone numbers “either closed or unattainable.” Sometimes a ransomware attack also results in inaccessible telephone lines.
The importance of Nucor plays in supporting the US critical infrastructure would also make it a primary target for ransomware -attackers. No threat actors have yet assumed the responsibility, and we do not know if sensitive data was taken in the violation.
Nucor is headquartered in Charlotte, North Carolina, and is widely regarded as the largest American steel producer and one of the best re -friend. It operates more than 300 facilities throughout the United States, Canada and Mexico and manufactures a wide range of steel products. Last year, it reported net sales of $ 30.73 billion annually.
