Scoped to one indicator with skopnix confidence 72/100 from 2 independent sources; checked against RFC1918/reserved space, CDN / cloud / scanner ranges and top-site lists (MISP warninglists), GreyNoise when enriched, and skopnix's benign-infrastructure list. Re-validate against last_seen before blocking: infrastructure is re-assigned.

How to deploy on Cortex XDR

  1. 1.Paste the XQL into Incident Response > Investigation > Query Builder > XQL Search.
  2. 2.To alert, save it as a Correlation Rule and set the MITRE tactic and technique printed with the rule.
  3. 3.Schedule it on the interval you hunt at; keep the fields stage for the alert's columns.

Check · CVE rules read PAN-OS URL logs (panw_ngfw_url_raw), which need the NGFW integration and, for HTTPS, decryption.
