If the court rules that these large scale attacks are an act of war, then expect to see the cyber insurance market lose most of its premiums…:
[…] By the end of 2017, Merck estimated initially in regulatory filings that the malware did $870 million in damages. Among other things, NotPetya so crippled Merck’s production facilities that it couldn’t meet demand that year for Gardasil 9, the leading vaccine against the human papillomavirus, or HPV, which can cause cervical cancer. Merck had to borrow 1.8 million doses—the entire U.S. emergency supply—from the Pediatric National Stockpile. It took Merck 18 months to replenish the cache, valued at $240 million. (The Centers for Disease Control and Prevention say the stockpile’s ability to deliver medicine wasn’t affected.)
Merck did what any of us would do when facing a disaster: It turned to its insurers. After all, through its property policies, the company was covered—after a $150 million deductible—to the tune of $1.75 billion for catastrophic risks including the destruction of computer data, coding, and software. So it was stunned when most of its 30 insurers and reinsurers denied coverage under those policies. Why? Because Merck’s property policies specifically excluded another class of risk: an act of war.
Merck went to court, suing its insurers, including such industry titans as Allianz SE and American International Group Inc., for breach of contract, ultimately claiming $1.3 billion in losses.
In a world where a hacker can cause more damage than a gunship, the dispute playing out in a New Jersey courtroom will have far-reaching consequences for victims of cyberattacks and the insurance companies that will or will not protect them. Until recently, the big worry associated with cyberattacks was data loss. The NotPetya strike shows how a few hundred lines of malicious code can bring a company to its knees.
