Google has implemented a system in Android 16 to alert users of potential fake cell towers, a technology used by both malicious actors and law enforcement agencies. This attack works by exploiting the fact that smartphones automatically connect to the network with the strongest signal, even if it's a fake tower emulating a cellular network. By connecting a device to such a tower, an attacker can gain access to the device's information (e.g., IMEI) and attempt to force the connection to a vulnerable standard like 2G, which allows for the interception of voice calls and messages. However, this new feature relies on modem driver support, and until devices with pre-installed Android 16 and corresponding hardware are available, users will not have full protection against this threat. The increasing use of fake cell towers poses a significant risk to mobile users, and it's essential for individuals to be aware of this issue and take necessary precautions to safeguard their devices and personal data.
