Google has a new problem: original add-on developers are being bought out by ad firms and their creations equipped with code serving ads to unsuspecting users.
However hard Google works to prevent malicious apps from being offered on Google Play, its official online Android market, some always get through.
Statistics say that Android malware and aggressive adware is on the rise, so the fact that researchers occasionally find some of it on legitimate online app markets should not come as a surprise to anyone.
With adware gleaning more user data from people devices than they would normally need too and developers bundle more than one adware framework into their apps, user privacy is increasingly taking a backseat to profit for developers and advertisers.
Pinterest, the extremely popular pinboard-style social photo sharing website, has launched official apps for Android, iPad and iPhone back in April, but that hasn't stopped scammers and ad-pushers from pushing out some of their own.
