improve rule
- improve rule logic
- match zeek fields for fields section
- add false positive information
- change rule name to match the logic of the original rule.. Rule said "first" seen, however, no logic that matches that (ie: rare, stacking, etc..)

Suspicious DNS Z Flag Set
The DNS Z flag is bit within the DNS protocol header that is, per the IETF design, meant to be used reserved (unused). Although recently it has been used in DNSSec, the value being set to anything other than 0 should be rare. Otherwise if it is set to non 0 and DNSSec is being used, then excluding the legitimate domains is low effort and high reward.
