Key Point 1: Android's Google Play Protect now includes a real-time app scanning feature to prevent the installation of potentially harmful sideloaded apps.

Key Point 2: Despite Google's rigorous efforts, a handful of predatory loan apps and fake app knock-offs managed to bypass the new security measures during testing.

Google Play Protect, the integral security mechanism for Android, has introduced a real-time app scanning feature designed to detect and block the installation of malicious apps that are sideloaded — a method that bypasses the official app store. This enhanced security initiative comes as a response to the increasing inventiveness of bad actors who constantly adapt their software to avoid detection.

The real-time scanning involves a thorough analysis of an app's code by Google Play Protect, flagging and preventing installation if the app poses potential risks. This feature is Google's latest attempt to safeguard users from predatory loan apps, which have had severe consequences for affected individuals, and other forms of malware that exploit personal data.

In a hands-on review, TechCrunch tested the effectiveness of the updated Google Play Protect by attempting to install over 30 known malicious apps, including stalkerware, spyware, and fake versions of popular apps. The majority were successfully blocked with warnings about their unsafe nature.

However, during the evaluation, certain predatory loan apps and fake app knock-offs succeeded in installation, highlighting the ongoing challenge in the battle against such software.

To ensure comprehensive security, Play Protect's intervention is now a prerequisite for all new, unscanned apps, extending the defense beyond the apps available in the Google Play Store.

The latest update to Google Play Protect underscores the dynamic and evolving nature of Android's security infrastructure. With millions of apps and the prevalence of sideloading, the real-time scanning feature stands as a critical barrier against malicious threats, embodying Google's commitment to user safety in the digital realm.
