Android Malware Anatsa Resurfaces in Google Play
Android malware Anatsa has once again managed to infiltrate Google Play. This time, it disguised itself as a PDF viewer app. The malicious app, called Document Viewer – File Reader, was published by a developer using a misleading name. Before it was discovered, the app had already surpassed 50,000 downloads.
Anatsa is a dangerous banking trojan. It targets Android users, especially those using mobile banking apps in North America. Once installed, the malware activates immediately. It silently tracks when users open banking apps, then launches an invisible overlay to steal login data and automate transactions.
How the Trojan Steals Information
The malware displays a fake notice over the real banking app. For example, it might claim that the system is undergoing maintenance. This trick hides the malicious activity and stops users from noticing unauthorized transactions.
While the fake notice shows, Anatsa records keystrokes, captures account details, and may even control the app. Therefore, users are unable to stop it in real-time or report any suspicious behavior quickly.
A Pattern of Infiltration
Anatsa operators have done this before. In fact, researchers have tracked it through several campaigns since 2021. One past version reached over 300,000 downloads. Another campaign in mid-2024 distributed two fake tools that infected 70,000 devices.
The strategy is the same each time. At first, the app appears harmless. However, once it gains enough users, the malware is added through an update. Then it connects to a remote server to install the Anatsa payload. From there, it begins spying on targeted banking apps.
The most recent attack occurred between June 24 and June 30, 2025. After being alerted by security researchers, Google removed the app from the Play Store.
How to Stay Protected
To avoid malware like Anatsa, always install apps from verified developers. Avoid unnecessary apps and read reviews carefully. If you installed this malicious app, uninstall it, scan your phone with Play Protect, and change your banking credentials immediately.
You can also use mobile threat detection tools and application behavior monitoring to block threats before they act. These advanced services detect anomalies early and prevent deep infiltration, offering real-time protection for mobile users.
