Identity Findings

Weak DKIM RSA key (~1296 bits) for selector 'k1'
RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.
💡 Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.
high
Weak DKIM RSA key (~1296 bits) for selector 'mandrill'
RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.
💡 Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.
high
No MTA-STS record found
Without MTA-STS, mail transport encryption cannot be enforced and is vulnerable to downgrade attacks.
💡 Publish a _mta-sts TXT record and host a policy file at https://mta-sts.conocophillips.com/.well-known/mta-sts.txt
medium
STARTTLS without MTA-STS or DANE protection
STARTTLS alone is vulnerable to downgrade attacks. Neither MTA-STS nor DANE is configured to enforce encryption.
💡 Deploy MTA-STS and/or DANE to protect against STARTTLS stripping attacks.
medium
No CAA records found
No CAA records are configured. Any certificate authority can issue certificates for this domain.
💡 Add CAA records to restrict certificate issuance. Example: 0 issue "letsencrypt.org"
medium
No TLS-RPT record found
Without TLS-RPT, you will not receive reports about TLS negotiation failures.
💡 Publish a _smtp._tls TXT record (e.g. "v=TLSRPTv1; rua=mailto:tls-reports@conocophillips.com").
low
Very low TTL on MX record: 278s
The MX record has a TTL of 278s or less (below 300s).

2 NS records have a TTL of 278s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.

Attack Surface Findings

DNSSEC is not enabled
No DNSKEY or DS records were found. DNS responses are not cryptographically authenticated.
💡 Enable DNSSEC by generating DNSKEY records and publishing DS records at the registrar.
medium
Domain enumerability: low
The domain has low enumerability. Proper NSEC3 configuration and limited CT exposure reduce the attack surface.
low
No internal information leakage detected
No non-routable IP addresses or internal references were found in public DNS records.
pass
No excessive DNS information exposure detected
No HINFO, LOC, RP records, version disclosures, or zone walking vulnerabilities were found.
pass
3 subdomain(s) discovered for conocophillips.com
Subdomains were enumerated via Certificate Transparency logs, DNS wordlist brute-forcing, and DNS record analysis.
informational
0 certificate(s) found in CT logs
Certificate Transparency logs contain 0 certificate(s) for conocophillips.com and its subdomains. Each certificate reveals subdomain names.
informational
Wildcard DNS record detected
A wildcard DNS record exists for *.conocophillips.com, resolving to 138.32.33.226. Wildcard records make subdomain brute-forcing less effective but may mask misconfigurations.

Dependency Chains

DMARC Authentication Chain (SPF)
DMARC uses SPF to verify that emails come from authorized servers
SPF Record SPF record found and configured DMARC Policy DMARC policy: reject
DMARC Authentication Chain (DKIM)
DMARC uses DKIM to verify that emails have not been tampered with
DKIM Signature DKIM signature missing DMARC Policy DMARC policy: reject
⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
Mail Server Identity: conocophillips-com.mail.protection.outlook.com
PTR record proves mail server legitimacy
MX: conocophillips-com.mail.protection.outlook.com Mail server at 52.101.194.12 PTR Record Reverse DNS: mail-ch0pr04cu00504.inbound.protection.outlook.com

Enforced Encryption Chain
MTA-STS enforces TLS encryption to prevent man-in-the-middle attacks
TLS Support Mail servers support TLS encryption MTA-STS Policy Mode:
Brand Identity Chain
BIMI displays your logo in email clients, but requires DMARC enforcement
DMARC Enforcement DMARC policy: reject BIMI Record BIMI not configured
⚠️ BIMI record is missing. Even with DMARC enforcement, you need to configure BIMI to display your brand logo in supported email clients.
TLS Monitoring Chain
TLS-RPT provides reports about TLS connection failures
TLS Support Mail servers support TLS encryption TLS-RPT Reporting TLS-RPT not configured
⚠️ TLS-RPT is not configured. Without TLS reporting, you have no visibility into TLS connection failures that may be impacting email delivery.
