How can I recognise which cookies are genuine?


I have installed two browser extensions: Privacy Badger and ScriptSave in order to block unwanted cookies. I knew websites would load cookies but I was still surprised by the number. Unfortunately, the web content is usually not displayed and I am eventually forced to allow all cookies to be loaded at least for a session. I can see there are different groups of them: analytics, cdn, tag managers, but some of them have randonly generated names.

I would guess following cookies are not dangerous:

cdn.cookielow.org cdn.sstatic.net cdnjs.cloudflare.com googletagservices.com google-analytics.com adjax.googleapis.com assets.hearstapps.com (?) 

But sometimes cookies with random names are loaded:

dstik9906m659.cloudfront.net d176jfkp3gfyt8.cloudfront.net d1bg94bbsh66ji.cloudfront.net 

I read anything with cloudfront.net is from amazon. I couldn’t find anything on the cookies above but I still don’t understand the reason for random characters in names?

I am looking for advice on how to be able to recognise genuine cookies and filter out those potentially dangerous. Is it easily possible? Thanks.
