A covert implant for authorised security testing. Use it only on systems you own or have written permission to test; intercepting other people’s data is a crime in every country listed here. Radio equipment needs certification where you live (FCC, CE, UKCA, ISED, Anatel). Some devices are uncertified or restricted in Brazil. Buyers are responsible for their local law.
