[Paywall may apply] “The costly NotPetya cyberattack, which the U.S. blamed on Russia, should be considered a ‘cyber nuclear attack,’ insurers argued as they urged judges to overturn a legal win by Merck & Co. in a dispute that could have broad ramifications for business insurance…The insurers appealed after a lower court judge sided with Merck in 2021. That judge found that based on the plain meaning of the policy language, the exclusion didn’t apply. Groups representing businesses of all kinds, from hospitals to manufacturers to restaurants, have come forward to back Merck, arguing that they depend on having reliable coverage.”
The company lost $1.4 billion in 2017’s NotPetya attack, which has been linked to Russia, but insurers are fighting in court to avoid paying.
