DeepSec 2019 Talk: How To Create a Botnet of GSM Devices – Aleksandr Kolchanov

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. Also, often they are vulnerable, so GSM-devices are interesting targets for hackers and pranksters. But it is easier to hack a device than to find these devices (usually, you should make a call, send SMS with a command to the phone number of this device, so it is necessary for an attacker to know or find this number).

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 GSM-alarms and smart homes controllers.
