A malware attack cost a shipping company up to $300m

"A.P. Moller-Maersk, the world’s largest container ship and supply vessel company, said Tuesday that it would incur hundreds of millions in U.S. dollar losses due to the NotPetya wiper malware attacks of late June.
In its second quarter earnings report, Maersk executives said they were expecting losses between $200 million and $300 million. The lost revenue, they said, was due to “significant business interruption” because the company was forced to temporarily shutter critical systems infected with the malware.
“The malware was contained to only impact the container related businesses of A.P. Moller – Maersk, and therefore six out of nine businesses, including all Energy businesses, could uphold normal operations,” the company said in its earnings report. “A.P. Moller – Maersk also remained in full control of all vessels throughout the situation, and all employees were safe.”"
