Android Backdoor Pre-Installed On Devices — Thousands Already Infected
- Kaspersky researchers discovered Keenadu, an Android backdoor embedded in firmware of devices from multiple makers, giving attackers unlimited control over infected devices as of February 2026.
- Kaspersky says the malware spreads via compromised firmware OTAs, other backdoors, embedded system apps, modified APKs and Google Play; Alldocube acknowledged an OTA server compromise and a malicious August 18, 2023 firmware on the iPlay 50 mini Pro.
- In its firmware-integrated variant, Keenadu compromises the libandroid_runtime.so core library to operate within every app, silently installs apps, monitors Chrome browser incognito searches, and resists standard Android OS removal tools.
- Some Google Play apps reached 300,000 downloads before removal, with 13,000 infected devices confirmed by Kaspersky , and researchers advise finding clean firmware or replacing devices while warning of broad data theft risks.
- Embedding in system apps for facial recognition increases stealth, but malware stops if Google Play Store and Play Services are absent, while researchers compare Keenadu to Triada across multiple device makers and low-cost supply chains.
