DNS data shows some aging or gaps — consider re-scanning for critical decisions

The following DNS record TTLs deviate from recommended values. Incorrect TTLs can cause caching issues, slow propagation, or unnecessary DNS traffic.

Record Type Observed TTL Typical TTL Severity Context
NS 870s 1 day (86400s) high NS TTL is below typical — observed 870s, typical value is 1 day (86400s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 86400 seconds per NIST SP 800-53 SI-18 relevance guidance. Use the TTL Tuner for profile-specific recommendations.
SOA 870s 1 hour (3600s) medium SOA TTL is below typical — observed 870s, typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 3600 seconds per NIST SP 800-53 SI-18 relevance guidance. Use the TTL Tuner for profile-specific recommendations.
A 15 minutes (900s) 1 hour (3600s) medium A TTL is below typical — observed 15 minutes (900s), typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 3600 seconds per NIST SP 800-53 SI-18 relevance guidance. Use the TTL Tuner for profile-specific recommendations.

Big Picture Questions

  • How often do you actually change this record? If it hasn’t changed in months, a short TTL is generating unnecessary DNS queries without any benefit.
  • Are you preparing for a migration or IP change? Short TTLs make sense temporarily — but should be raised back to 1 hour (3600s) once the change is complete.
  • Every DNS lookup adds 20–150ms of latency. With a 60s TTL, returning visitors trigger a fresh lookup every minute. With 3600s, they get cached responses for an hour — faster page loads, no extra infrastructure needed.
  • Google runs A records at ~30s because they operate a global anycast network and need to steer traffic dynamically. For a typical website without that infrastructure, copying those TTLs increases query volume with zero upside.
Tune TTL for evilhacker.com
Reference: NIST SP 800-53 SI-7 (Information Integrity) · RFC 8767 (Serve Stale) · RFC 1035 §3.2.1 (TTL semantics) Note: Some DNS providers (e.g., AWS Route 53 alias records, Cloudflare proxied records) enforce fixed TTLs that cannot be modified. If a finding targets a record you cannot edit, it reflects the observed value rather than a configuration error on your part.

Email Security Methodology Can this domain be impersonated by email? Yes no SPF or DMARC protection

SPF Record RFC 7208 §4 Verified

Does this domain declare who may send email on its behalf? No
Warning

No SPF record found

RFC Stance: RFC 7208 defines the SPF mechanism for domains that choose to publish sender authorization. The standard does not mandate SPF publication — it is a voluntary security control.
Operational Security: We flag its absence because any server on the internet can send email claiming to be this domain. Attackers send from a domain — they do not need the domain to have email infrastructure.
RFC Failure Mode: Unlike DMARC (where unknown tags are silently ignored per RFC 7489 §6.3), SPF with unrecognized mechanisms produces a PermError per RFC 7208 §4.6 — the record fails loudly rather than silently.
Related CVEs: CVE-2024-7208 (multi-tenant domain spoofing), CVE-2024-7209 (shared SPF exploitation), CVE-2023-51764 (SMTP smuggling bypasses SPF)

DMARC Policy RFC 7489 §6.3 Verified

Are spoofed emails rejected or quarantined? No policy published
Warning

No DMARC record found

RFC Stance: RFC 7489 is classified as Informational (not Standards Track). DMARC is a widely adopted industry practice but is not an IETF-mandated standard.
Operational Security: Without DMARC, receiving mail servers have no policy for handling SPF/DKIM failures. Spoofed messages may be delivered to recipients.
DMARCbis (Pending): draft-ietf-dmarc-dmarcbis will elevate DMARC to Standards Track, obsolete RFC 7489, replace 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.
Related CVEs: CVE-2024-49040 (Exchange sender spoofing), CVE-2024-7208 (multi-tenant DMARC bypass)

DKIM Records RFC 6376 §3.6 Verified

Are outbound emails cryptographically signed? Not discoverable
Not Discoverable

DKIM not discoverable via common selectors (large providers use rotating selectors)

RFC 6376 (Provider-Managed) — DKIM signing managed by the detected mail provider per RFC 6376.
Known Vulnerabilities: DKIM 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

Can attackers downgrade SMTP to intercept mail? Not prevented
Warning

No MTA-STS record found

MTA-STS policy enforcement is evaluated in Mail Transport Security below.

TLS-RPT RFC 8460 §3 Verified

Will failures in TLS delivery be reported? No reporting
Warning

No TLS-RPT record found

DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? No
RFC 7672 §3 RFC 6698 §2 Not Configured

No MX records available — DANE check skipped

DANE (RFC 7672) binds TLS certificates to DNSSEC-signed DNS records, protecting email transport against man-in-the-middle attacks and rogue CAs. It is the primary transport security standard — MTA-STS (RFC 8461) was created as the alternative for domains that cannot deploy DNSSEC. Over 1 million domains use DANE globally, including Microsoft Exchange Online, Proton Mail, and Fastmail. Best practice: deploy both for defense in depth.
Email Transport Security

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).
This domain has neither DANE nor MTA-STS. Mail transport relies on opportunistic TLS without policy enforcement, leaving it vulnerable to downgrade attacks. Deploy DANE (RFC 7672) with DNSSEC for the strongest protection, or MTA-STS (RFC 8461) if DNSSEC is not feasible.

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

Is the brand identity verified and displayed in inboxes? No

No BIMI record found

CAA RFC 8659 §4 Verified Warning

Does this domain restrict who can issue TLS certificates? No

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

  • http://evilhacker.com/
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.

Analyze Another Domain

Confirm Your Email Configuration

This tool analyzes DNS records, but to verify actual email delivery, send a test email to Red Sift Investigate. Their tool shows exactly how your emails arrive, including SPF/DKIM/DMARC pass/fail results in the headers.

DATA FRESHNESS & METHODOLOGY

All security-critical records (SPF, DMARC, DKIM, DANE/TLSA, DNSSEC, MTA-STS, TLS-RPT, BIMI, CAA) are queried live from authoritative nameservers and cross-referenced against 5 independent public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, DNS4EU) at the time of each analysis. No security verdict uses cached data.

Registrar data (RDAP) is cached for up to 24 hours because domain ownership and registration details change infrequently. Certificate Transparency logs (subdomain discovery via RFC 6962) are cached for 1 hour because CT entries are append-only historical records. Sections using cached data are marked with a CACHED badge; live queries show LIVE.

Intelligence Sources

This analysis used 4 DNS resolvers (consensus), reverse DNS (PTR), Team Cymru (ASN attribution), IANA RDAP (registrar), crt.sh (CT logs), and SMTP probing (transport). All using open-standard protocols.
