Per one tech forum this week: “Google has quietly installed an app on all Android devices called ‘Android System SafetyCore’. It claims to be a ‘security’ application, but whilst running in the background, it collects call logs, contacts, location, your microphone, and much more making this application ‘spyware’ and a HUGE privacy concern. It is strongly advised to uninstall this program if you can. To do this, navigate to 'Settings’ > 'Apps’, then delete the application.”
No, that wouldn’t make much difference. I don’t think I’ve seen a real world attack via SMS that even bothered to “forge” the from-field. People are used to getting texts from unknown numbers.
And how would you possibly implement this supposed “caller-id” for a field that doesn’t even have to be set to a number?
