Google recently gave an overview of their efforts to get rid of malicious apps from Google Play specifically for Android.
In a blog post, Google Play Director of Product Management Trust & Safety, Krish Vitaldevara, provided information that Google removed approximately 119,000 app developer accounts last year, and also prevented more than 962,000 apps classified as dangerous from appearing on the Play Store.
Our core efforts around identifying and mitigating bad apps and developers continued to evolve to address new adversarial behaviors and forms of abuse.
In essence, Vitaldevara wants to inform Android users around the world that until now Google continues to try to identify and mitigate bad or dangerous applications and developers so they don't continue to wage guerrillas in the 'Google Play Developer Console' which will potentially lead to various abuses.
Google understands that this is a challenge that must be faced even into 2021. Because basically the Google Play Developer Console (a portal for uploading your .apk) itself, can be accessed by everyone without any 'special restrictions'.
New policy as a preventive measure against the entry of malicious applications on the Play Store
Google is aware that despite its efforts, until now Google Play is not completely empty of malicious apps.
To address these challenges, Google imposed a series of new policies on Google Play to help reduce the entry of malicious apps from irresponsible developers.
Play Protect as the front line of application security on Google Play still needs to be improved and even Google in its blog said that they are still far from perfect.
There have even been several recent reports that say that the apps on Google Play are infected with malware.
