Dialog after Big Sur Update 9/30/21

Did you follow the dialog’s instructions and look in the Security & Privacy System Preference? It should show the name of the software for which an extension is trying to install.

I googled “Kirill Luzanov Mac app” (I added the other terms because there’s probably more than one person with that name in the world) and found a listing that suggests they’re a developer for the Mac app DriveDx, is that something you have installed?

The first link in the google search seemed to go to an outdated site (formidapps.com), DriveDx seems to be currently offered by Binary Fruit. Another search result associated their name with a kernel extension for SAT SMART Driver, another program from Binary Fruit.
