IMSI-catcher
An IMSI-catcher is a special device that bad guys can use to find out where somebody's phone is and even listen to their phone calls. Imagine if you had a special device that could shout very loudly and pretended to be a phone tower. When somebody near you is using their phone, it would try to connect to your device because it thinks it's a real phone tower. This is what an IMSI catcher does.
The IMSI-catcher will then ask for the phone's unique identification number, called an IMSI, and other information like the phone's number, which the bad guys can use to track the phone's location and carry out further attacks. They can even listen to phone calls and get text messages in real-time, even if they're encrypted.
So, you know how you have to be careful around strangers, especially those who want to take your things? The same goes for your phone. If you ever come across someone using a strange device around you, make sure they're not trying to steal your phone's data. Always be careful and protect yourself from bad guys who want to use IMSI-catchers.
