A new app update means a new APK Teardown here at AP. Today's victim is the Google Play Store, which was just freshly updated to 3.9.16. We've got all sorts of stuff to talk about.
A Built-In Malware Scanner
Yes, it's hard to believe, but Google is working on a malware scanner for the Play Store. The string file doesn't lie:
<string name="package_malware_title">App Check</string>
<string name="package_malware_consent_text">"Allow Google to check all apps installed to this device for harmful behavior?
To learn more, go to Settings > Security."</string>
<string name="package_malware_banner_warning">Installing this app may harm your device</string>
<string name="package_malware_banner_blocked">Installation has been blocked</string>
<string name="package_malware_recommendation_warning">Google recommends that you do not install this app.</string>
<string name="package_malware_recommendation_blocked">To protect you, Google has blocked the installation of this app.</string>
<string name="package_malware_app_name">App name: \"%s\"</string>
<string name="package_malware_checkbox_label">I understand that this app may be dangerous.</string>
<string name="package_malware_consent_title">Verify apps?</string>
Apparently, there are two parts to this.
