![]() There are many companies that manufacture both CPUs and BRPs. To the CPU, the BRP is a black box, but one with extensive access to the device’s main memory where user data is stored. The BRP’s executable code is written into it by the vendor, and it’s effectively inaccessible to smartphone apps for analysis or modification. Nevertheless, the BRP has its own memory and a rather complex command system - in fact, it’s a full-fledged highly-specialized processor that actively exchanges data with the CPU and main memory. Once a dedicated chip, for more than a decade now it has been commonly integrated with the CPU. The BRP usually doesn’t include Wi-Fi or Bluetooth functions. What is a BRP?Ī baseband radio processor (BRP) is the part of a smartphone, tablet, or other smart technology that handles wireless cellular communication in second to fifth-generation devices: Thankfully, there are temporary protective measures you can take. But in the meantime you need to keep yourself and your phone safe. ![]() These vulnerabilities can be fixed only with a firmware update – yet to be released. For the rest, either the mobile operator itself must perform malicious actions, or the hacker needs direct access to the device. ![]() Four of them are critical and allow an attacker to remotely execute code on a victim’s device without any action on their part. This is due to the presence of 18 vulnerabilities in the Exynos baseband radio processor, which is widely used in Google, Vivo, Samsung, and many other smartphones. Bug hunters at Google Project Zero say you just need the victim’s phone number. Smartphones, tablets, and even cars with Samsung Exynos microprocessors are at risk of remote hacking.
