The off-road tire plant in Normal is among many affected by a cyberattack on Bridgestone Americas operations in North and Central America.
The company sent workers at many of its facilities in the U.S. and Canada home after the attack began early Sunday morning. Company spokesperson Emily Weaver said the incident was ongoing at the Normal-based plant as of Monday morning.
Weaver said no one in the Twin Cities was sent home or experienced a shift interruption as a result of the attack.
"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," Weaver said in a statement.
The Bridgestone plant in Normal employs around 450 workers, according to a press release from the company. Workers there make tires for large mining, construction, forestry and other oversized vehicles.
Weaver said many facilities in North and Latin America have been removed from the Bridgestone computer network as a precaution.
