Android-IMSI-Catcher-Detector [1] claims to prevent silent app installation through GTalkService, in this issue [2] from 2014. However I can't find any other source confirming this is possible. So is it probable to force remote install with fake cell tower? How about permissions of the app installed that way, would data be compromised? Would phone factory reset remove software installed that way?[1] https://cellularprivacy.github.io/Android-IMSI-Catcher-Detector/

NB: Android-IMSI-Catcher has been removed from F-Droid and Aptoide for some reason.
