Cyber­ attack disrupted the worldwide operations


In June 2017, the company disclosed that it had suffered a "network cyber ­attack" resulting in the disruption of its worldwide operations, including manufacturing, research and sales operations. It was reported that as many as 30,000 laptops/desktops were taken off line as were 7,500 servers in the immediate response to the incident.

The cyber attack shut down production for weeks, reportedly causing $1.3 billion in damage and leading to litigation when many of the company's insurers and reinsurers denied coverage for the event claiming the Russia-linked attack constituted an act of war. In January 2022, a US court ruled in favour of the company in a lawsuit filed against its insurer.
