Owner of app that hijacked millions of devices with one update exposes buy-to-infect scam

The owners of a popular barcode scanner application that became a malicious nuisance on millions of devices with one update insist that a third-party buyer was to blame.

Earlier this month, cybersecurity firm Malwarebytes explored how a trusted, useful barcode and QR code scanner app on Google Play that accounted for over 10 million installs became malware overnight.

Having gained a following and acting as innocent software for years, in recent months, users began to complain that their mobile devices were suddenly full of unwanted adverts.

Barcode Scanner was fingered as the culprit and the source of the nuisanceware, tracked as Android/Trojan.HiddenAds.AdQR. The researchers tracked malicious updates as the reason -- with aggressive advert pushing implemented in the app's code.

The app's analytics code was also modified and updates were heavily obfuscated.
