An Android malware strain camouflaged as a system app is used by threat actors to disable the Google Play Protect service, generate fake reviews, install malicious apps, show ads, and more.
The heavily obfuscated malware dubbed Trojan-Dropper.AndroidOS.Shopper.a uses a system icon and the ConfigAPKs name which closely resembles the name of a legitimate Android service responsible for app configuration the first time a device is booted.
