An international mobile subscriber identity-catcher, also known as an IMSI catcher, is a telephone eavesdropping device that is used to intercept mobile phone communications and monitor the location data of mobile phone users throughout the world. It is referred to as a man-in-the-middle (MITM) assault because it is essentially a “fake” mobile tower that acts between the target mobile phone and the service provider’s genuine mobile towers. Due to the reciprocal authentication needed by both the phone and the network, the 3G wireless standard provides certain risk mitigation benefits to users. Complex assaults, on the other hand, may be able to downgrade 3G and LTE network services to non-LTE network services, which do not need mutual authentication to operate.
However, their usage has created serious civil liberties and privacy issues in a number of nations, including the United States, where they are rigorously controlled by the Strafprozessordnung Code of Criminal Procedure and the German Strafprozessordnung StPO/Code of Criminal Procedure. Due to the fact that certain nations do not have encrypted phone data traffic (or just have extremely poor encryption), an IMSI catcher is not required.
