new android tablets, especially cheap ones, might come with malware pre-installed right from the factory.

kaspersky found keenadu, a backdoor hidden in the firmware of some budget brands like alldocube.

it's baked into core system libraries, not something you download.

every app you open triggers it.

attackers get full control: they install apps silently, hijack your browser, run ad fraud in the background, burn your battery and data.

the files are digitally signed, so android thinks they're legit. no alerts, looks totally normal.

factory reset does nothing. the malware lives in the firmware, it's part of the device forever.

basically makes the whole tablet untrustworthy.

cheap devices can come with big risks. think hard before buying super low-priced android tablets.
