Android barcode scanner with 10 million+ downloads infects users
Researcher says Google hasn't removed the malicious app, so onus is on end users.

A benign barcode scanner with more than 10 million downloads from Google Play has been caught receiving an upgrade that turned it to the dark side, prompting the search-and-advertising giant to remove it.
Barcode Scanner, one of dozens of such apps available in the official Google app repository, began its life as a legitimate offering. Then in late December, researchers with security firm Malwarebytes began receiving messages from customers complaining that ads were opening out of nowhere on their default browser.
In the case of Barcode Scanner, malicious code had been added that was not in previous versions of the app. Furthermore, the added code used heavy obfuscation to avoid detection. To verify this is from the same app developer, we confirmed it had been signed by the same digital certificate as previous clean versions. Because of its malign intent, we jumped past our original detection category of Adware straight to Trojan, with the detection of Android/Trojan.HiddenAds.AdQR.
