I mean just small back ground checks would at least keep such malicious extensions from making it to the store.
It do comes to my mind that Google should be held responsible with these hacking incidents yet they should impose some strict criterias for an app to be listed without having any shady malwares inside of it.Due to lots of apps that been flooding out and knowing this store has the most wide variety when it comes to apps then they do come into the point that their standards of security had significantly goes down too thats why we are seeing these situations.
People do have some common impressions when it comes to those apps that being listed or downloaded on google playstore which they do highly believe that it is legit and trustable.Even myself do still hesitant on downloading into this store and im making myself too paranoid when we do talk about security matters.
