Technical Details



Trojan:Android/Gepew variants are reportedly installed on a mobile device as part of the payload of a PC-based trojan, Droidpak. When this trojan infects a Windows system, it downloads a mobile app onto the machine and then attempts to install it onto any Android devices connected to the system by a USB cable. For installation to be successful, the device must have the setting 'Enable USB debugging' enabled.

When installed, Gepew will scan the device for installed apps associated with South Korean banks. If found, Gepew prompts the user to remove these apps; if complied with, trojanized versions of these apps are installed. The trojan may also monitor and intercept incoming SMS messages, which are forwarded to a remote server. For more information, see:
