We can do many things using our mobile devices: hail a taxi, book a hotel, send and receive money, purchase goods online or in-store, chat and share media files, control other devices (such as door locks or security cameras) and more. But then there’s the other side of the equation: All these activities and conveniences create a huge cyberattack surface. The problem can be anywhere: in the local network, on your device, connected via Bluetooth or USB cable, exploiting vulnerabilities from far away. Cybercriminals can even use your smartphone speakers—for example, a malicious application can deliver voice commands to your Google Assistant.
