Engineer's DNS Intelligence Report
| Parameter | Current | Suggested | Severity | Rationale |
|---|---|---|---|---|
| timeout_seconds | 5s |
8s |
low | Average scan duration is 36.4s, suggesting DNS responses are slow for this domain. Increasing timeout from 5s to 8s prevents premature resolution failures. RFC 8767 |
Add a DMARC record to protect your domain against email spoofing and receive authentication reports.
| Field | Value |
|---|---|
| Type | TXT |
| Host | _dmarc.mobilecommercepress.com (DMARC policy record) |
| Value | v=DMARC1; p=none; rua=mailto:dmarc-reports@mobilecommercepress.com |
DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.
CAA records specify which Certificate Authorities may issue certificates for your domain, reducing the risk of unauthorized certificate issuance.
| Field | Value |
|---|---|
| Type | CAA |
| Host | mobilecommercepress.com (root of domain — adjust CA to match your provider) |
| Value | 0 issue "letsencrypt.org" |
TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain.
| Field | Value |
|---|---|
| Type | TXT |
| Host | _smtp._tls.mobilecommercepress.com (SMTP TLS reporting record) |
| Value | v=TLSRPTv1; rua=mailto:tls-reports@mobilecommercepress.com |
MTA-STS enforces TLS encryption for inbound mail delivery, preventing downgrade attacks on your mail transport.
| Field | Value |
|---|---|
| Type | TXT |
| Host | _mta-sts.mobilecommercepress.com (MTA-STS policy record) |
| Value | v=STSv1; id=mobilecommercepress.com |
Email Security Methodology Can this domain be impersonated by email? Likely SPF alone cannot prevent spoofing
SPF Record RFC 7208 §4 Verified
SPF valid with industry-standard soft fail (~all), 4/10 lookups
DMARC Policy RFC 7489 §6.3 Verified
No DMARC record found
pct= with t= (testing flag), add np= (non-existent subdomain policy), and mandate DNS tree walk for policy discovery instead of the Public Suffix List.DKIM Records RFC 6376 §3.6 Verified
DKIM not discoverable via common selectors (large providers use rotating selectors)
l= tag body length vulnerability (attacker appends unsigned content to signed mail),
weak key exploitation (keys below 1024-bit are cryptographically breakable per RFC 6376 §3.3.3),
DKIM replay attacks (re-sending legitimately signed messages at scale)
MTA-STS RFC 8461 §3 Verified
No MTA-STS record found
MTA-STS policy enforcement is evaluated in Mail Transport Security below.
TLS-RPT RFC 8460 §3 Verified
No TLS-RPT record found
DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? No
No DANE/TLSA records found (checked 1 MX host)
Two mechanisms protect email in transit. DANE is the primary standard; MTA-STS is the alternative for domains that cannot deploy DNSSEC:
- DNSSEC + DANE (RFC 7672) — Cryptographic chain of trust from DNS root to mail server certificate. Eliminates reliance on certificate authorities. No trust-on-first-use weakness. Requires DNSSEC.
- MTA-STS (RFC 8461) — HTTPS-based policy requiring TLS for mail delivery. Works without DNSSEC but relies on CA trust and is vulnerable on first use (§10). Created for domains where “deploying DNSSEC is undesirable or impractical” (§2).
Industry trend: Microsoft Exchange Online enforces inbound DANE with DNSSEC (GA October 2024), and providers like Proton Mail and Fastmail also support DANE. Google Workspace does not support DANE and relies on MTA-STS. Both mechanisms coexist because DANE is backward-compatible — senders skip the check if the domain isn't DNSSEC-signed (RFC 7672 §1.3).
Brand Security Can this brand be convincingly faked? Yes No DMARC policy (RFC 7489) — attackers can send email appearing to be from this domain with no sender-authentication barrier
BIMI BIMI Spec Verified Warning
No BIMI record found
CAA RFC 8659 §4 Verified Warning
No CAA records found - any CA can issue certificates
Vulnerability Disclosure Policy (security.txt) Is there a verified way to report security issues? No RFC 9116
No security.txt found
/.well-known/security.txt provides security researchers with a standardized way to report vulnerabilities.
See securitytxt.org for a generator.
AI Surface Scanner Beta Is this domain discoverable by AI — and protected from abuse? No
No AI governance measures detected
llms.txt llmstxt.org
AI Crawler Governance (robots.txt) RFC 9309 IETF Draft
Content-Usage Directive IETF Draft
Content-Usage: directive for robots.txt that lets site owners declare whether their content may be used for AI training and inference. This is an active draft, not yet a ratified standard.
Content-Usage: ai=no to robots.txt to deny AI training, or Content-Usage: ai=allow to explicitly permit it.
Without this directive, AI crawler behavior depends on individual crawler policies and User-agent rules.

Public Exposure Checks Are sensitive files or secrets exposed? No
No exposed secrets detected in public page source — same-origin, non-intrusive scan of publicly visible page source and scripts.
What type of scan is this?
This is OSINT (Open Source Intelligence) collection — we check the same publicly accessible URLs that any web browser could visit. No authentication is bypassed, no ports are probed, no vulnerabilities are exploited.
Is this a PCI compliance scan? No. PCI DSS requires scans performed by an Approved Scanning Vendor (ASV) certified by the PCI Security Standards Council. DNS Tool is not an ASV. If you need PCI compliance scanning, engage a certified ASV such as Qualys, Tenable, or Trustwave.
Is this a penetration test? No. Penetration testing involves active exploitation attempts against systems with authorization. Our checks are passive observation of publicly accessible resources — the same methodology used by Shodan, Mozilla Observatory, and other OSINT platforms.
Mail Transport Security Beta Is mail transport encrypted and verified? No No MTA-STS or DANE — mail transport encryption is opportunistic only
No transport encryption policy detected — mail delivery relies on opportunistic TLS
Policy Assessment Primary
No transport enforcement policies detected. Mail delivery relies on opportunistic STARTTLS, which is vulnerable to downgrade attacks (RFC 3207). Consider deploying MTA-STS (RFC 8461) or DANE (RFC 7672).
