Forbes reported in September 2025 month the U.S. Immigration and Customs Enforcement (ICE) has been using IMSI catchers (or “Stingrays”) to monitor people’s movements and communications. These “stingrays” force nearby devices to connect, allowing authorities to collect phone identifiers, track locations, and in some cases, intercept calls or texts.
This follows a July report of cell phone surveillance detected at an ICE protest in Washington state.
IMSI catchers don’t just capture data from specific targets—they scoop up information from everyone nearby. That means ordinary people’s phones can be swept into government surveillance without their knowledge or consent.
At Cape, we’re deeply concerned about this type of surveillance. That’s why we’ve directly supported the Electronic Frontier Foundation’s (EFF) research into counter-surveillance technologies like Rayhunter, which helps detect these threats. Read about EFF’s findings, and Cape’s contributions, here.
