CamScanner is one of the most downloaded document scanning apps worldwide. Recently, has been removed from the Play Store because, in one of its updates, malicious code was injected.
This app worked correctly and allowed quick digitization
of documents to PDF. That is why this app quickly gained a good reputation and downloads were counted in the millions. Nevertheless, the security brand Kaspersky discovered that
one of its modules hid a trojan that allowed hackers to download and install
malicious content on the device, make purchases and, even, take control of it.
Este módulo malicioso estaba integrado en una librería de
terceros de publicidad. That is why, Google no pudo encontrar la infección con
su sistema de comprobación de aplicaciones, requisito que han de superar los desarrolladores para publicar las aplicaciones en la tienda. However, aún seguimos
encontrando la aplicación en su versión de pago en la Play Store, since, al no tener ésta el módulo
de publicidad, no se encuentra infectada.
