Quote:A total of 50 malicious apps have managed to bypass Google's security checks and land on the Google Play store, leading to millions of installs on Android devices.
 
It was only last week that researchers from Check Point uncovered a total of six apps laden with the PreAMo ad fraud malware on Google Play which had been installed 90 million times.

Now, the cybersecurity team from Avast have found a further 50 apps relating to lifestyle services which masquerade as legitimate software but are actually adware, and these malicious apps have been downloaded a total of 30 million times.
 
On Tuesday, Avast published a report on the discovery, in which the apps are linked to each other through third-party libraries that "bypass the background service restrictions present in newer Android versions."

"Although the bypassing itself is not explicitly forbidden on the Play Store, Avast detects it as Android:Agent-SEB [PUP], because apps using these libraries waste the user's battery and make the device slower," the researchers say. "The applications use the libraries to continuously display more and more ads to the user, going against Play Store rules."
