Posture summary

Ransomware leak-site listings (1)

This domain is named on the public leak site of a ransomware group. A leak-site post is a claim published by the group — not a verified fact, and not a statement by this organization. Groups list victims who did not pay, overstate what they hold, and occasionally name the wrong company. What is certain is that the listing itself is public.

Leak-site postings are collected here from 2026-07-30 onwards; an earlier listing would not appear above.

Lookalike domains (3 registered of 150 checked, 3 serving no website)

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.

Recommendations

• highEnforce DMARC

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

• highPublish SPF

  No SPF record was observed. Publish one listing authorized senders.

• mediumEnable DNSSEC

  DNSSEC signing was not detected for this domain.

• criticalTreat data published on a leak site as disclosed

  This domain is named on Eclipse's public leak site on 2026-09-14. A leak-site post is a claim published by the group, not a verified fact — but the post itself is public, and if it is accurate the data is already out. Confirm the claim, then work from the assumption of disclosure: rotate every credential that touched the affected systems, invalidate active sessions, and check your notification duties under GDPR Art. 33/34.

• highMonitor lookalike domains

  1 registered lookalike domain(s) can receive mail, which is what makes them usable for invoice fraud and credential phishing. 1 of those serves no website at all — registered, silent and already able to accept a reply. A name in that state is typically pointed at something only when it is about to be used, so it is worth watching before anything appears on it. Monitor them and consider defensive registrations.
