Dangerous Android malware targets US banking apps - 50,000 people already affected, make sure you're not next

• Security researchers found a PDF app for Android sporting a banking trojan
• The trojan was introduced with a patch, six weeks after release
• It had more than 50,000 downloads, so users should beware

A dangerous Android banking trojan has found a way to the Google Play Store once again, potentially affecting tens of thousands of North American users, experts have warned.

Security researchers from Threat Fabric found an app on the Play Store, called ‘Document Viewer – File Reader’, published by a company called ‘Hybrid Cars Simulator, Drift & Racing’ roughly two months ago and having amassed a significant following - some 50,000 people.

Until only recently, the app was clean, working as intended. Then, between June 24 and 30, it received an update that turned it into a banking trojan called Anatsa.
