Divide and conquer: how the new Keenadu backdoor exposed links between major Android botnets

This report analyzes Keenadu, a sophisticated firmware-level Android backdoor found embedded in libandroid_runtime.so and various system apps across multiple tablet vendors; the malware hooks into Zygote to inject into every app, implements a binder-based AKServer/AKClient architecture to load signed AES-encrypted modules (clickers, search-hijackers, monetizers, and credential-stealers), employs supply-chain compromise during firmware build for distribution, and is linked operationally to other large botnets such as Triada, BADBOX and Vo1d; the report includes technical behavior, IoCs, distribution vectors, and remediation guidance.
