After months of diplomatic engagement, the early morning of February 24, 2022 saw what President Biden called an "unprovoked and unjustified attack by Russian military forces" on Ukraine. Numerous news reports also have described significant cyber attacks against Ukrainian systems. According to those reports, these attacks follow multiple waves of cyber attacks in the past few weeks that have targeted Ukrainian banks and government websites, including those of the Ukrainian parliament, and ministries of foreign affairs and defense.1 As Ukrainian systems are targeted, businesses around the world are at risk of spillover effects, the spread of any new malware beyond Ukraine's borders, and the risk of increased ransomware attacks. In this Legal Update, we highlight recent security recommendations that can serve as resources for companies working to protect their systems during this period of acute cyber risk.
