"Some apps, mainly banking ones, exercise non permit screenshots to live on taken when they are on top. In such cases, the Trojan has about other choice to pocket information – it draws its phishing window over the attacked app," Unuchek says. 

"It is interesting that, inwards social club to uncovering out which app is on top, it uses accessibility services too."

All the stolen information is hence uploaded to the attackers' command as well as command (C&C) server. As purpose of his research, Unuchek said he managed to intercept an encrypted configuration file from the malware's C&C server.

Decrypting the file helped him uncovering out about of the websites as well as apps that Svpeng targets, equally good equally aid him obtain a URL with phishing pages for both the PayPal as well as eBay mobile apps, along with links for banking apps from the United Kingdom, Germany, Turkey, Australia, France, Poland, as well as Singapore.
