malware – Hybrid-Analysis.com indicates the website that my macOS system is contacting is likely malicious

Backstory…

I just upgraded my macbook from OS X 10.11.6 to the most updated version of macOS, 10.14.6 Mojave. I also have the Little Snitch network filter installed. I know nearly nothing about information security, so when I see my computer connecting to a website in another country for reasons I can’t determine, I get a little paranoid.

For example, my network filter is showing me that my computer is contacting a particular website adriver.ru, and it’s being contacted by a built-in system file: /System/Library/StagedFrameworks/Safari/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.Networking.xpc

I did a google search and Hybrid-Analysis says that this is a potentially malicious website… https://www.hybrid-analysis.com/sample/aeb562d94494fd967c0ef064f528956192bcff8b00033c0f9892d7cafeda174e?environmentId=120

How should I interpret:

  1. Every strange connection my macOS computer makes?
  2. Hybrid-Analysis.com telling me my built-in macOS software is contacting a malicious website?

Could it be that a legitimate, built-in process on macOS Mojave is hacked?

Am I overreacting, or should I still keep a gun next to my toaster?

As a side question: When should I stop worrying about every website my computer connects to?
