We are pleased to present this White Paper addressing decisions rendered by U.S. Courts in 2021 on the law of insurance coverage for cyber risks. Many more decisions from recent years are addressed in our earlier White Papers entitled, respectively, Cyber Risks and Insurance Coverage Decisions 2020 and Cyber Risks and Insurance Coverage Decisions 2015-2019. Those addressed decisions involving a broad range of risks, including ransomware, cyber extortion, network interruption, data breaches, lost data, lost software, disabled hardware, cryptomining losses, liability from websites and social media, deceptive funds transfers, social engineering, and bitcoin theft. Like the decisions in this White Paper, the earlier decisions arose under various types of policies, including CGL, Businessowners, Computer Fraud, Crime, Financial Institution, Cyber, D&O, and Homeowners. Thus, the prior White Papers present a survey of the most important recent decisions involving "silent cyber" or "non-affirmative cyber" coverage. If you would like to receive copies of these earlier White Papers, please contact me at the email address below. The body of relevant law continues to emerge, and many novel, complex and challenging issues lie ahead.
