Some employees at Bridgestone's Warren County plant were sent home Sunday due to a possible cyber attack. Bridgestone provided no update Monday when asked when workers may return and when production might resume.

Bridgestone Americas confirmed that it learned of a potential information security incident and has launched an investigation.

The company said in a news release it has disconnected some manufacturing and retreading facilities in North America and Latin America from its network. This includes the Warren County plant, which produces truck and bus radial tires and is a global leader in tire manufacturing. 

The Warren County plant employs right at 1,100.

Bridgestone has made the following statement:

"Bridgestone Americas is currently investigating a potential information security incident. Since learning of the potential incident in the early morning hours of Feb. 27, we have launched a comprehensive investigation to quickly gather facts while working to ensure the security of our IT systems. Out of an abundance of caution, we disconnected many of our manufacturing and retreading facilities in Latin America and North America from our network to contain and prevent any potential impact.

We are continuing to make progress on the investigation towards determining the scope or nature of any potential incident, and we will continue to work diligently to address any potential issues that may affect our operations, our data, our teammates, and our customers."
