- Nucor confirmed to suffer from a cyber attack
- He was forced to close the parts of his operations to contain the incident
- No threat actor has yet claimed responsibility
Nucor, one of the largest steel manufacturers in the United States, was forced to close the parts of its operations to approach an ongoing cyber attack. The company has confirmed the news in a new 8-K form filed with the Securities and Exchange Commission (SEC) of the United States.
In the file, Nucor said that he had recently observed an “unauthorized third party” access to “certain information technology systems”. When he spotted the intrusion, he activated his response plan to incidents, brought in a third -party cybersecurity company to help and informed the law enforcement agencies concerned.
However, it also took “potentially affected offline systems” to implement “other confinement, sanitation or recovery measures”.
Was it ransomware?
Nucor told the dry that she had “temporarily” and proactively “arrested certain production operations in various places” in an abundance of prudence “. He now restarts these operations, he added.
Usually, when a company closes its operations to contain a cyber attack, it generally ends up being a ransomware attack. Although the company has not explicitly said it, the fact that it has interrupted operations could suggest that this is the case.
In addition, the register tried to reach out to the company’s facilities in the United States, but has found many “closed or new” telephone numbers. Sometimes a ransomware attack also causes inaccessible telephone lines.
The importance that Nucor plays to support the American critical infrastructure would also make it a main target for ransomware attackers. No threat player has yet claimed responsibility, and we do not know if sensitive data has been taken in the violation.
Nucor has its registered office in Charlotte, in North Carolina, and is largely considered to be the largest producer of American steel and one of the best recyclers. It operates more than 300 facilities in the United States, Canada and Mexico and manufactures a wide range of steel products. Last year, he declared annual net sales of $ 30.73 billion.
