After dozens of hacking incidents, Google needs to more closely scrutinize apps published on its app store and thoroughly vet third-party apps that use the Reproduction Protection feature. The worst part is that hackers are embedding malware into pre-installed apps that come with a new device. Therefore, users should be more suspicious of the apps they use.
