Posture summary

Public attack surface (8 hostnames in Certificate Transparency)

Hostnames this organization published in public TLS certificates. Passive OSINT — nothing was scanned; a wildcard certificate is in use, so the real footprint may be larger.

The hostname inventory — which forgotten hosts exist and where — is part of the complete audit for this domain.

Lookalike domains (15 registered of 45 checked)

Registered permutations of this domain. Existence is a fact, not an accusation — ownership and intent are not assessed. Those able to receive mail are the ones usable for invoice fraud and phishing.

12 further registered lookalike(s), 11 of them able to receive mail. The full list, with mail capability for each, is part of the complete audit.

Recommendations

• highEnforce DMARC

  No enforcing DMARC policy was observed. Publish a DMARC record and move to p=quarantine then p=reject to reduce spoofing.

• mediumEnable DKIM

  No DKIM record was found on common selectors. Enable DKIM signing.

• mediumEnable DNSSEC

  DNSSEC signing was not detected for this domain.

• highEnable valid HTTPS

  No valid TLS was observed on port 443.

• highReset credentials seen in infostealer logs

  Public infostealer telemetry associates 4 employee credential set(s) with this domain — passwords captured from infected devices, which bypass password policy and often session-hijack past MFA. Force a reset for the affected services, invalidate active sessions, and check the devices themselves.

• highMonitor lookalike domains

  11 registered lookalike domain(s) can receive mail, which is what makes them usable for invoice fraud and credential phishing. Monitor them and consider defensive registrations.
