“Craftsart Cartoon Photo Tools,” one of the most popular mobile apps on the official Google Play store, has registered more than 100,000 downloads. However, the app is actually infected with Facestealer Android malware.
The app, which pretends to be a legitimate photo editor, was deemed somewhat safe by Pradeo’s security experts. Through a variety of filters, it can be used to convert photos into cartoons or painting-style images.
Facestealer steals Facebook credentials by using social engineering and connects to a Russian server. Google Play has often exposed Facestealer as a threat via trojanized apps since it’s a known threat.
However, Google Play has been informed about this discovery by Pradeo analysts, who advise users to delete the app immediately.
