Remediation Guide & Defensive Action Plan

Immediate Action Required: Delete the Strikingly CNAME record from authoritative DNS.

Defensive Verification Checklist:

Audit authoritative DNS zone records for any CNAME pointing to *.strikinglydns.com.
Verify whether the target resource or bucket still exists under your organization's cloud tenant.
If decommissioned, delete the DNS record immediately to close the public exposure window.
Deploy a pre-merge IaC security gate (such as SubdomainWatch Takeover Guard) to intercept dangling records before pull requests merge.
