What happens when the attacker modifies /etc/resolv.conf, disables or does not use DNS while on the network.
What if the attacker does not use software that automatically loads images, like the "canary token" tracking pixels?
What is the attacker opens the files offline?
Canary tokens still work? How?
Why would anyone advise using canary token instead of port knocking? Makes no sense. Why not use both?
