The rzepeckimroczkowski Listed by darkrace Ransomware Group (reported June 5, 2023) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.

Ransomware groups continue to target mid-sized commercial organisations across Europe, using data theft and public leak-site pressure as core tactics. In this environment, even specialised automotive dealerships have appeared on criminal listings, raising practical questions for customers, staff and partners about what may have been taken and how far the exposure reaches.

On 5 June 2023 the organisation known as rzepeckimroczkowski was listed by the darkrace ransomware group. Public detail is limited: the number of people affected remains unknown, and the only data category named is internal files said to have been exfiltrated in a ransomware attack. The listing itself is a claim by the group; independent confirmation of the full scope has not been supplied in the available record.

Breaking down the breach

According to the reported information, Rzepecki Mroczkowski Sp. Z o.o. appeared on a darkrace leak site on 5 June 2023. The group asserted that internal files had been exfiltrated during a ransomware attack. No public figure has been given for the volume of data, the number of systems involved, or the precise date the intrusion began. The count of individuals potentially affected is listed as unknown. Method of initial access, duration of presence inside the network, and whether encryption was also deployed are not disclosed in the available facts. What is stated is simply that the organisation was named by darkrace and that internal files were claimed as stolen.

Because the record does not include further technical indicators, timelines or verification statements from the company, the incident must be treated as an asserted listing rather than a fully documented forensic account. Readers should therefore regard the scale and exact contents as unconfirmed pending any additional official disclosure.

The group behind it: darkrace

Darkrace is a ransomware operation that has followed the now-common double-extortion model: encrypting systems where possible while also copying data and threatening to publish it on a dedicated leak site if payment is not made. Like other groups in this category, it has historically posted victim names, sample files and countdown timers to increase pressure. Public reporting on darkrace has described it as one of several actors that emerged or rebranded in the broader ransomware ecosystem, often focusing on organisations that hold commercially sensitive or customer-related records.

In the present case the group claims to have exfiltrated internal files from rzepeckimroczkowski. No additional statements attributed to darkrace about this specific victim—such as ransom demands, file counts or screenshots—are contained in the facts provided. The listing should therefore be understood as the group’s assertion, not as independently verified detail.

Who is rzepeckimroczkowski?

Rzepecki Mroczkowski Sp. Z o.o. is a Polish automotive company that has been linked to the Volkswagen Group since 1991. It operates as an authorised dealer for Volkswagen passenger cars and Volkswagen Commercial Vehicles. Its headquarters are located in Poznań at ulica Wiatraczna 5, where it also runs authorised service operations and sells original spare parts for Volkswagen, Volkswagen Commercial Vehicles, Audi and Škoda.

Dealerships of this type routinely manage vehicle sales contracts, service histories, parts inventories, customer contact details, financing or leasing paperwork, and internal business records. A breach affecting such an organisation is consequential because the data held can touch both private individuals (vehicle owners and service customers) and commercial counterparties (fleet clients, suppliers and manufacturer systems). Even when the precise contents of a theft remain unconfirmed, the sector’s typical data holdings make the incident relevant beyond the company itself.

The information in question

The only data category named in the available record is “internal files exfiltrated in ransomware attack.” No further breakdown—customer databases, financial documents, employee records, service histories or otherwise—has been supplied. The number of people affected is explicitly unknown.

Organisations of this kind ordinarily store customer names and contact information, vehicle identification and service data, warranty and parts records, employee information, and internal commercial documents. It is reasonable to note that such material could be among internal files, yet it is not established fact that any specific category was taken. Exact contents remain unconfirmed; any assessment of personal exposure must therefore stay provisional until more detail emerges.

Why it matters

For individuals, the practical risks centre on the possible misuse of personal or vehicle-related information if it was among the taken files. That can include targeted phishing that references real service visits or purchase details, attempts at identity fraud, or unwanted contact. Because the scale is unknown, it is impossible to say how many people, if any, face elevated risk; the prudent stance is simply to treat the possibility seriously.

For the organisation the consequences include operational disruption, potential regulatory scrutiny under data-protection rules, reputational damage with customers and the manufacturer network, and the cost of investigation and remediation. A public listing by a ransomware group also creates ongoing uncertainty until the company can clarify what was actually removed and whether systems have been fully restored and secured.

None of these outcomes require assuming negligence; they follow from the nature of ransomware incidents and the kinds of records a dealership holds. The absence of confirmed victim counts or data inventories simply means the full picture is not yet public.

What to do if you're exposed

If you have been a customer, employee or partner of Rzepecki Mroczkowski, begin by watching for unexpected messages that reference your vehicle, service history or personal details. Treat unsolicited requests for payment, passwords or further personal data with caution. Consider placing fraud alerts with relevant credit or identity services if you believe sensitive identifiers may have been involved, and change passwords on any accounts that reused credentials linked to the dealership.

Keep records of any suspicious contact and report clear fraud attempts to local authorities. You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets; that step provides a quick, concrete way to assess whether your details appear in wider circulating collections and to decide on further monitoring.

Publicly posted by darkrace — unverified claim, pending independent verification

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.

Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company or group named on this page.
