Most of the operating systems warn users to back up their data before a software update. This is more of a disclaimer in a rare event that your data is wiped. However, a new Chromebook software update is sure to wipe your device clean! The patch is pretty important as it addresses the TPM bug. The TPM or Trusted Platform Module is entrusted with generating and creating cryptographic keys that will protect the local data. A recent bug allowed hackers to brute-force attack and access encrypted data.
While the attack in itself is not easy and is time-consuming for the hackers, Google sprung into action and issued an update. This update will improvise the feature on the Infineon TPM chip. Wondering why this isn’t a system-wide update? Well, the chip’s firmware is secluded from the operating system, and thus it doesn’t warrant for a system-wide update. That being said, the TPM bug affects more than 100 Chromebooks, and the odds of your device figuring out in the list is high.
In order to check the system for the TPM bug, all you need to do is type “chrome://system” in the URL bar and then hit enter. Once the settings menu opens, press Ctrl+F and search for “TPM.” Expand the TPM version button, and if any versions are listed below, it means that your system is affected by the TPM bug and an update is available.
As explained earlier, it is only possible to install this update after wiping your device. So make sure that you backup all your data. Now head over to the System Settings>Advanced>Powerwash. Click the checkbox that mentions “Update firmware for added security.” Proceed as usual with the rest of the settings. I would suggest all the affected Chromebook users update the systems asap and stay safe from hacking attacks.
