On January 29, 2024, the Department of Commerce (“Department”) published a proposed rule (“Proposed Rule”) to require providers and foreign resellers of U.S. Infrastructure-as-a-Service (“IaaS”) products to (i) verify the identity of their foreign customers and (ii) notify the Department when a foreign person transacts with that provider or reseller to train a large artificial intelligence (“AI”) model with potential capabilities that could be used in malicious cyber-enabled activity. The proposed rule also contemplates that the Department may impose special measures to be undertaken by U.S. IaaS providers to deter foreign malicious cyber actors’ use of U.S. IaaS products.  The accompanying request for comments has a deadline of April 29, 2024.
