A supply chain attack has planted backdoors inside the firmware of multiple Android tablet makers. Incidents of tainted firmware updates have been traced back to as far as August 2023.
The firmware images were infected with a new backdoor named Keenadu.
Spotted and analyzed by Kaspersky in a report released on Tuesday, the backdoor is injected in Zygote, the central core process of the Android operating system from where it cannot be removed without a full device flash and reinstall.
