Google Play Apps Hide Anatsa Banking Trojan Using Stealthy Loaders
Malicious applications distributed through Google Play are employing stealthy loaders to install the Anatsa banking trojan for Android, putting victims' financial accounts at risk. The campaign relies on seemingly legitimate programs to conceal the initial infection stage, with one identified case involving a modified PDF reader that displays a fake update prompt to trick users into installing an additional component. Another loader discovered in the Cleanova application collects data from analytics SDKs, including installation source details, and forwards this information to a command-and-control server. The server then decides whether to deliver the malicious payload based on predefined criteria, leaving the code inactive for non-targeted victims to evade automated analysis. Once Anatsa is installed, the threat can facilitate theft of credentials used for financial services and enable fraudulent transactions. Banking trojans represented 30.77 percent of detected malicious mobile applications in the second quarter of 2026, during which more than 1.99 million attacks involving malware, adware, or unwanted programs were blocked and 93,574 banking trojan installation packages were identified.
