Is there any inherent risk in running software that has not been updated?

I’m curious as I’ve been running DNS66 on my previous and current phone and whilst it does exactly what it says (blocks all ads across the device) my concern is that the last published update in fdroid sas 2021.

I’m currently running AdAway which has been more recently updated and does an equally good job of blocking in-app ads.

My question though is more, if the software is still doing what it was intended to do is there a fundamental risk in using software that is no longer being updated?

phx,

Depends on the software, what it does, known vulnerabilities (in the software itself but also underlying libraries etc).

Since it is likely intercepting DNS and blocking known ad domains, it could be vulnerable to exploits which rely on malicious encoding in DNS records etc

Anticorp,

There’s no need to update if there are no known exploits. A lot of companies push updates just to force a new privacy policy these days. Not every update is a security patch or new feature, unfortunately.

JackbyDev,

2021 isn’t that long ago to be honest.
