Better understanding and mitigating the risks of using a phone that no longer receives system updates
Better understanding and mitigating the risks of using a phone that no longer receives system updates
Too many perfectly usable phones are put into a questionable security situation by lack of vendor support for keeping key software up to date.
But what's the actual risk of using an Android phone on a stock ROM without updates? What's the attack surface?
It seems like most things that'd contact potentially malicious software are web and messaging software, but that's all done by apps which continue to receive updates (at least until the android version is entirely unsupported) eg. Webview, Firefox, Signal, etc.
So are the main avenues for attack then sketchy apps and wifi points? If one is careful to use a minimal set of widely scrutinised apps and avoid connecting to wifi/bluetooth/etc. devices of questionable provenance is it really taking that much of a risk to continue using a device past EOL?
Or do browsers rely on system libraries that have plausible attack vectors? Perhaps images, video, font etc. rendering could be compromised? At this point though, that stack must be quite hardened and mature, it'd be major news for libjpg/ffmpeg to have a code-execution vulnerability? Plus it seems unlikely that they wouldn't just include this in webview/Firefox as there must surely be millions of devices in this situation so why not take the easy step of distributing a bit more in the APK?
I'm not at all an Android developer though, perhaps this is very naive and I'm missing something major?
You're viewing a single thread.
They will soon pass a law in France where they can remotely enable GPS, audio, camera. That's the kind of problem you will encounter if your phone has OS backdoor due to lack of updates and a shitty government.
If your phone is old and obselete, then your OS likely lacks the backdoor that will now be required by the government to be installed in order to facilitate the Guantanamo-fication.
Backdoor in the sense of CVE i mean, not backdoor introduced by the government.
That's not what you said though. You mentioned the government backdoors, which can only really apply to new phones (or updates to existing phones). Common Vulnerabilities and Exploits is a separate issue, where if you have an older phone there's a greater chance it will have an unpatched vulnerability.
No i said 2 things: OS backdoor, and shitty government that passes laws to snoop on their citizen. But i agree that vulnerabilities makes more sense.
There's no difference. If the government can get in, so can criminals.
I wish Android phones should have kill switches like pine phones.
