A ransomware group operating under the name Safepay has posted a claim on its dark web leak site alleging that it accessed systems belonging to Marlin HVAC, a company operating the domain marlinhvac.com, on or around September 15, 2026. This listing was identified by ransomware.live, a security research platform that continuously monitors the public-facing extortion portals used by ransomware groups. It is important to stress that this is a claim made by a criminal group seeking leverage or publicity, not a confirmed security incident. Marlin HVAC has not issued any public statement confirming or denying the allegation, and no independent forensic verification has taken place at this time.
What has surfaced so far, and where the gaps remain
- Claimed date of the alleged incident: September 15, 2026
- Group behind the claim: Safepay, via its leak-site posting
- Company’s line of business: general commercial services (HVAC-related), categorized here under a broad ‘other’ sector
- The specific categories of data the group alleges to have obtained — such as customer records, employee files, or financial documents — have not been disclosed in the listing and remain unconfirmed
- No regulatory filing, breach notification, or law enforcement statement has surfaced to corroborate the claim as of publication
Precautions worth taking while the situation is unresolved
- Update passwords tied to accounts associated with Marlin HVAC, especially if reused elsewhere, and avoid recycling credentials across services
- Turn on two-factor authentication wherever it is offered, particularly for email and financial accounts
- Stay alert for phishing attempts, fraudulent invoices, or unexpected contact referencing HVAC services, appointments, or billing — these are common follow-up tactics after alleged breaches
- Consider enrolling in an identity monitoring service such as a service like Aura or LifeLock to get early warning if personal information turns up in unexpected places
- Keep an eye on bank and credit card statements for unfamiliar activity in the weeks following any such claim
BreachLetter will revisit and update this article if Marlin HVAC issues a confirmation, if regulators are formally notified, or if additional verifiable details emerge regarding this claim.
