LAFAYETTE, Ind. (WLFI) -- At least two Lafayette automotive plants are stopping work Monday night. It comes as the FBI confirms they are investigating a large ransomware attack affecting some local companies.

Subaru of Indiana Automotive and Heartland Automotive, which is a Subaru supplier, both canceled their second shifts. Employees were told it's possible other shifts could be affected too.

An SIA spokesperson said the shift cancellation was due to a "supplier issue" and declined to name the supplier.

When asked if they were investigating a cyber attack affecting Subaru, an FBI spokesperson in Indianapolis gave this statement:

"The FBI is aware of a ransomware attack and the significant impact that the attack has had on certain companies in the state of Indiana. Due to the ongoing investigation, no further details will be released at this time."

News 18 will continue to follow this story as more information about upcoming shifts becomes available.
