FRANKFURT (Reuters) - German chemicals company BASF said it currently had no indication that a network disruption affecting logistics at its Ludwigshafen headquarters was caused by a cyber attack.

“There is currently no reason to assume that the disruption was caused by hacking. Our experts are still at an early stage of investigating the cause,” a spokeswoman said.

The group said in a statement on Thursday that the incident was mainly affecting a warehouse and rail traffic at the Ludwigshafen chemical complex, the group’s largest, which could lead to delayed checking-in of delivery trucks at some gates.
