onyx-fire.com Listed by lockbit3 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure organisations by pairing encryption with data theft and public leak-site listings, turning internal files into leverage. In that landscape, the appearance of onyx-fire.com on a LockBit3 listing in early September 2023 fits a familiar pattern: a claim of exfiltration, a volume figure, and a promise of further disclosure if demands are unmet.

Public reporting on 6 September 2023 stated that Onyx-Fire Protection Services Inc, operating as onyx-fire.com, had been listed by the LockBit3 ransomware group. The listing asserted that internal files had been taken in a ransomware attack. The number of people affected remains unknown, and independent confirmation of the full scope has not been published in the available record.

Breaking down the breach

According to the reported summary tied to the listing, the incident involved Onyx-Fire Protection Services Inc, a firm in the security and investigations sector. LockBit3’s claim described internal files exfiltrated in a ransomware attack and referenced a volume of 800 GB. Named categories in that summary included financial documents such as balance sheets, budgets, profit-and-loss reports, expense reports, bank statements, and statements of payables and receivables, with the list appearing truncated in the public note.

The date associated with the public report is 6 September 2023. No detailed timeline of initial access, dwell time, or negotiation has been disclosed in the facts available. The count of individuals whose information may have been involved is unknown. Method of intrusion—phishing, exposed remote access, supply-chain compromise, or another vector—is not described in the public material. What stands in the record is the group’s leak-site listing and the characterisation of the material as internal files taken during a ransomware event.

Inside lockbit3

LockBit3 is a well-documented ransomware operation that has, over successive iterations, run as a Ransomware-as-a-Service model. Affiliates gain access to victim environments, deploy the encryptor, and often exfiltrate data before encryption so the group can threaten publication on a dedicated leak site. The brand has been associated with high-volume campaigns against organisations of many sizes and sectors, using double-extortion pressure: restore access only after payment, or face staged release of stolen files.

Public reporting on LockBit3 has long noted automated negotiation portals, countdown timers on leak pages, and the use of stolen data samples to prove possession. Law-enforcement actions and infrastructure disruptions have affected the ecosystem at various points, yet listings under the LockBit name have continued to appear. In this case, the group claims onyx-fire.com as a victim and claims exfiltration of internal material; those assertions originate from the actors themselves and should be treated as unverified claims unless corroborated by the organisation or independent investigation.

Who is onyx-fire.com?

Onyx-Fire Protection Services Inc, associated with onyx-fire.com, is described in the reporting as operating in the security and investigations industry. Firms in this sector typically provide protective services, fire- and life-safety related work, monitoring, or investigative support to commercial and other clients. They commonly hold contracts, site details, operational schedules, employee records, and financial and vendor information needed to run field and office operations.

A breach affecting such an organisation is consequential because the business sits at the intersection of physical security, client trust, and regulated or sensitive operational data. Disruption or exposure can affect not only the company but also clients who rely on it for protection-related services, and staff whose employment and payroll data may reside in the same systems. Public detail on the precise services portfolio and client base of onyx-fire.com beyond the industry label is limited in the breach record.

The information in question

The facts name the exposed material as internal files exfiltrated in a ransomware attack. The reported summary attached to the LockBit3 listing further claims a volume of 800 GB and points to financial documents, including balance sheets, budgets, profit-and-loss reports, expense reports, bank statements, and statements of payables and receivables, with additional items indicated but not fully spelled out in the truncated note.

Exact contents across the full claimed set are not independently confirmed in the available record. Organisations of this kind typically also hold employee personal data, client contracts, operational plans, and correspondence; whether any of those categories were included here remains unconfirmed. The number of people affected is unknown.

Why it matters

For the organisation, publication or circulation of internal financial files can expose banking relationships, cost structures, and commercial positions to competitors, fraudsters, or opportunistic actors. Ransomware incidents also carry operational cost: recovery, legal review, notification duties where they apply, and potential strain on client confidence in a security-oriented business.

For individuals—employees, contractors, or others whose details might appear in internal systems—the practical risks are more personal. Financial and administrative files can contain names, account references, salary or payable information, and contact data that support phishing, invoice fraud, or identity misuse. Because the affected population size is undisclosed and the full file inventory is unconfirmed, people connected to the company cannot yet know from public sources alone whether their own information was included. Calm monitoring of accounts and scepticism toward unexpected financial or HR-themed messages remain proportionate responses while facts stay limited.

If your data was in this claimed breach

If you have a relationship with Onyx-Fire Protection Services Inc or onyx-fire.com—as staff, vendor, or client—treat the LockBit3 claims as a signal to tighten basic hygiene rather than as proof that your records were taken. Practical first steps include:

• Watch bank, payroll, and credit activity for unfamiliar transactions or new account openings.
• Be wary of emails or calls that reference invoices, refunds, or internal documents and that urge urgent action.
• Use unique passwords and multi-factor authentication on email and financial accounts.
• Retain any notice the company may issue; official guidance will be more specific than leak-site claims.
• Consider a free exposure scan of your email address to see whether it has already appeared in known breach datasets elsewhere.

Public detail on this incident remains constrained to the September 2023 listing, the claim of internal-file exfiltration, the stated 800 GB figure, and the financial-document categories named in the summary. Further clarity would depend on confirmation from the organisation or from investigators. Until then, measured caution is the soundest course.
