The htop output says it has something to do with one of your gnome shell extensions. GJS (Gnome JavaScript) is a programming environment similar to Node.js. Gnome Shell and pretty much all the extensions are written in javascript if I'm not mistaken.
It appears to be this extension that adds icons to the desktop. Main website is here.
So it looks like the "rastersoft.com" part is just the name of the publisher of the extension and not a website that something is connecting to and "ding" is the name of the extension.
If you run the following command to list all files in your /usr/share/gnome-shell/extensions/ directory, you should see multiple directories that all follow the same extension-name@publisher format:
ls /usr/share/gnome-shell/extensions/
In the future, there are a couple of ways you can identify the package that contains a file on your system.
The first option is to use the apt-file command. First, install the application:
sudo apt update
sudo apt install apt-file
Next, update your file list:
sudo apt-file update
Finally, search for your file:
apt-file search /usr/share/gnome-shell/extensions/[email protected]/ding.js
This should list the package name gnome-shell-extension-desktop-icons-ng as the package that contains the file.
Also, you can search the contents of a package for filenames at packages.ubuntu.com and for this, we would need to search for ding.js and don't forget to set the distribution to Kinetic.
Here is a link to the result.
