I turned on my old HTC espresso after a decade and I remembered that I loved this app.
It creates an unique profile image for contacts without a profile picture
So now when you open the contact list instead of having a list of capital letters in a circle you have a list of capital letters in a more colorful circle
Unfortunately it’s now outdated and discontinued, but it still works on Android 14.
Seems like some asshole took the source code and republished the app as is, without credit, in the Amazon app store to get some financial incentive (around 2014 blackberry paid devs to republish their apps and many assholes decided that it was a good idea to “steal” open source apps)
After this, dev took development private but then got tired of the update treadmill that Google forces on the play store, so the apps were automatically delisted.
Luckily, fdroid doesn’t have such artificial limitations on outdated apps that still work as intended.
I would be wary of running outdated apps like that even if their main functionality remains unchanged as they are almost certainly using some vulnerable outdated dependencies.
Even for a 100% offline app?
The chance of something like this being exploited is much lower than a zero day on the browser you’re using right now
Not to mention that you can install it and then immediately uninstall it after it generated the profile pics
It likely parses the profile pictures with some image parsing libraries, those have frequent security issues.
