Recommended defensive actions

  • Apply Microsoft security updates for Office on all affected systems as soon as possible.

  • Verify patch compliance across the fleet rather than relying on deployment completion alone.
  • Monitor CISA KEV and Microsoft security advisories for any additional remediation guidance.
  • If patching is delayed, reduce exposure by limiting the handling of untrusted Office documents where operationally feasible.
