Researchers at Symantec have discovered a malicious app called Beaver Gang Counter that steals photos and videos from popular instant messaging and VoIP app, Viber. The malicious Beaver Gang Counter app (see below), disguised as a score-keeping app for a card game, was removed from the Google Play Store, after the researchers at Symantec informed Google about it.

How the Malicious App Works?
The malicious app silently searches for Viber photos and video files, once the files are located, they are uploaded or sent to a remote computer server operated by cybercriminals, where the cybercriminals may use them for criminal activities, such as identity theft, blackmail, fraud, or pornography.
