The location data we give up in using certain apps can be used by third parties to track our movements and infer our behaviors, preferences and beliefs. While this information may be relatively harmless when leveraged by a retailer or investor, there’s no telling who may ultimately gain access.

In September 2019, attribution was given to Israel for the IMSI catchers discovered in Washington, D.C. two years earlier, shining light on the prevalence of these types of spying devices. Once used solely by law enforcement as a way of finding the international mobile subscriber identity (IMSI) linked to a criminal suspect’s SIM card for investigative purposes, now just about anyone can acquire or build an IMSI catcher to intercept a target’s communications. With such low barriers to entry, it’s no longer just the bad guys who need to be worried about these devices.
