There are different types of GSM-devices: from GSM-alarms for homes and cars to industrial controllers, remote-controlled electric sockets and smartwatches for kids.

During this talk, I will give a short overview of types of devices and common vulnerabilities, then I will tell about different methods, which can be used to find the phone number of the device. Also, I will show some funny ideas, which allows hackers to create small (or huge, who knows?) botnet of
