According to BuzzFeed News, Democratic Senator Ron Wyden and Representative Ted Lieu will introduce legislation later today that seeks to restrict police use of international mobile subscriber identity (IMSI) catchers. More commonly known as Stingrays, police frequently use IMSI catchers and cell-site simulators to collect information on suspects and intercept calls, SMS messages and other forms of communication. Law enforcement agencies in the US currently do not require a warrant to use the technology. The Cell-Site Simulator Act of 2021 seeks to change that.
