S. 2425, the Intelligence Community Property Security Act of 2025, creates new criminal penalties for anyone who unlawfully accesses property controlled by U.S. intelligence agencies that is clearly marked as closed or restricted. The law establishes a tiered penalty system: a first offense carries a fine and up to 180 days in prison, a second offense can result in a fine and up to 3 years imprisonment, and a third or subsequent offense may lead to a fine and up to 10 years in prison. This bill amends the National Security Act of 1947 and affects anyone who enters restricted intelligence community facilities without authorization. The legislation does not specify new funding requirements or implementation timelines beyond the criminal penalties themselves.
