Hello
I am trying to create a custom object / custom spyware signature based on dns-req-section that would alert when the requested domain via dns is longer than x amount of characters.
Currently I am stuck at the pattern requirement to have 7 fixed bytes. Any ideas?
(We are not using dns proxying)
(I'm trying to detect this:

Thank you in advance
Kind regards
