This bill directs the Treasury Secretary to study how well the government and private sector coordinate their response to ransomware attacks targeting financial institutions. The Treasury Department must submit a comprehensive report to Congress within one year examining current coordination efforts, whether government agencies receive timely information about attacks, and whether financial institutions are withholding or delaying their reports to authorities. The report should also analyze existing reporting requirements, identify any gaps that might require new legislation, and recommend policy changes to improve information sharing and speed up response times to ransomware incidents. The Secretary must then brief Congress on the findings within 15 months. The bill does not authorize any funding or create new requirements for financial institutions themselves, but rather focuses on assessing the current system to determine if improvements are needed.
