• James Bottomley ☛ James Bottomley: Securing a Rooted Android Phone

  This article will discuss securing your phone after you’ve rooted it and installed your preferred os (it will not discuss how to root your phone or change the OS). Re-securing your phone requires the installation of a custom AVB key, which not all phones support, so I’ll only be discussing Surveillance Giant Google Pixel phones (which support this) and the LineageOS distribution (which is the one I use). The reason for wanting to do this is that by default LineageOS runs with the debug keys (i.e. known to everyone) with an unlocked bootloader, meaning OS updates and even binary changes to the system partition are easy to do. Since most android phones are fully locked, this isn’t a standard attack vector for malicious apps, but if someone is targetting you directly it may become one.
