One of the bodies that have the power to use this tool are regulatory bodies such as the police and also detectives such as the FBI who have special interests so that they are given a privilege to be able to use this tool legally.


How IMSI Catcher Works?


This tool works by mimicking a mobile tower that transmits and connects the network. So that this tool will later act as a fake mobile tower where smartphones that are around this tool will usually be directly connected automatically.


When a smartphone is connected to the IMSI catcher, the person behind the catcher's control can view and extract the data they want from the smartphone. The data that is usually sought after is the history of phone calls and also the contents of text messages.
