An IMSI Catcher operates by tricking mobile devices into connecting to it instead of the legitimate cell tower. The device acts as a fake cell tower and emits stronger signals than real towers nearby, causing mobile devices to connect to it automatically and spy on them.
Once a mobile device connects to IMSI Catcher, it can intercept and record the device’s communication information. This includes data such as phone calls, text messages, location, and other information transmitted over the phone network. They can spy on all the information on the phone, listen to all the calls and read your movements without you noticing.
This technique is widely used today by cybercriminals and there are more and more victims of this device, which we do not find out about until it is too late.
At Encriptados we have one of the best encrypted SIM Cards on the market, this SIM is designed so that IMSI catchers cannot triangulate or locate you. Just by carrying it on your device, you will be fully protected against these types of attacks no matter where you are.
Additionally, some encrypted mobile phones such as T2 Communicator, Armadillo or TotalSec, incorporate the IMSI Catcher Detection Function. These devices are designed to alert you if a possible triangulation or interception attempt is detected. By providing this additional security feature, these encrypted phones help protect your privacy and allow you to take steps to safeguard your personal information.
