Ransomware Attack Delays Shipyard Production at Marinette Marine Shipyard

Fincantieri Marinette Marine suffered a ransomware attack last week that delayed production across the shipyard. Large chunks of data on the shipyard’s network servers were rendered unusable by an unknown professional group.

The attack on Marinette Marine targeted servers that held data used to feed instructions to the shipyard’s computer numerical control manufacturing machines, knocking them offline for several days. CNC-enabled machines are the backbone of modern manufacturing, taking specifications developed with design software and sending instructions to devices like welders, cutters, bending machines and other computer-controlled tools.

Based on information from the Navy, it’s unclear if the attackers stole any data. The yard is currently on contract to build four combatants for the Saudis and three frigates for the U.S. Navy, with the service planning to ramp up procurement in the pursuit of buying two frigates per year. The Navy acknowledged the attack in a statement but did not provide additional details.
