I am a privacy conscious user and i dont like to be fingerprinted by marketing websites, So i setup my symantec firewall and closed most of the ports that i dont use. I also disabled icmp requests. Now when i access facebook, google or some other websites i see they do icmp requests and god knows what not. But there is something that amazed me.They are able to access my windows kernel files. I scanned all of my pc files and everything came out clean but in firewall logs i see these sites accessing Ntoskrnl.exe everytime i visit facebook, google etc. How is that even possible? Is there something residing in my router/modem?
Some of these tracking urls that can access Ntoskrnl.exe are
aa.online-matrix.net (owned by device fingerprinting company called threatmetrix)
loadm.exelator.com
loadeu.exelator.com (Both owned by a marketing company www.nielsen.com)
I have also attachec a image file, please check out and give me your insight
Thanks
