The following shows the process tree when HVNC is enabled.Įxplorer.exe (PID: 3140) is the child process of explorer.exe (PID: 2216), and is found in the process tree. A difference between normal VNC and HVNC used by TinyNuke is that the user does not realize that the PC is infected and its screen is being controlled. Due to its source code revealed in 2017, TinyNuke is used by various attackers, and the HVNC, Reverse SOCKS4 Proxy features are partially borrowed by other malware such as AveMaria and BitRAT.Īmong the various features of TinyNuke that are being distributed, only the HVNC feature is enabled. ![]() TinyNuke, also known as Nuclear Bot, is a banking malware discovered in 2016, and it includes features such as HVNC (HiddenDesktop/VNC), reverse SOCKS4 proxy, and form grabbing. One of the VNC malware that is installed is TinyNuke. ![]() Kimsuky group installs AppleSeed backdoor on the target system after the initial compromise, then additionally installs VNC malware via AppleSeed to ultimately control the target system in a graphical environment. Similar to the commonly-used RDP, it is used to remotely access and control other systems. VNC, also known as Virtual Network Computing, is a screen sharing system that remotely controls other computers. While monitoring Kimsuky-related malware, the ASEC analysis team has recently discovered that VNC malware was installed via AppleSeed remote control malware.
