"...a confession was obtained"
Considering it's Russia, I think we know what that means...
Russia's Ministry of the Interior has gone public about the March 24 arrest of a 25-year-old and four others it believes was the leader of a gang of cyber-scum behind the “Svpeng” money-draining malware.

Based on my experiences on Google Play, right now it is almost impossible to get any idea about an app's legitimacy or finances, even though most of them seem to be using minor variations of a few basic models...
