Koper Automatisering Listed by rhysida Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 15 June 2023, the ransomware group rhysida listed Koper Automatisering on its leak site, claiming that internal files had been taken in an attack and made available for public download. The number of people whose information may be involved remains unknown, and public detail about exactly what was taken is limited. For employees, business partners, and customers who deal with a specialist software firm serving the food and floriculture sectors, the practical stakes are straightforward: internal documents can contain contact details, contracts, operational records, and other material that outsiders can misuse for fraud, phishing, or competitive harm.

This article sets out only what has been reported, places the claim in the context of how rhysida typically operates, and explains what people can usefully do next without speculation.

What happened

According to the reported listing, Koper Automatisering was named by the rhysida ransomware group on or around 15 June 2023. The group stated that internal files had been exfiltrated in a ransomware attack and that documents had been uploaded to public access, with a claim that “all files” were made available. No confirmed figure for the number of people affected has been published. The precise method of initial access, the duration of any intrusion, and independent verification of the volume or full contents of the material remain undisclosed in the available record.

The listing itself is a claim by the group. Public reporting at the time did not supply a separate confirmation from the organisation or from law-enforcement sources that every asserted detail was accurate. What is known is the date of the report, the attribution to rhysida, and the description of the exposed material as internal files taken in a ransomware incident.

The group behind it: rhysida

Rhysida is a ransomware operation that emerged in public reporting in 2023 and has been associated with double-extortion tactics: encrypting systems while also copying data and threatening to publish it if a ransom is not paid. The group has maintained a leak site on which it names victims and, in some cases, posts samples or larger archives of stolen files. Like other actors in this category, rhysida has targeted organisations across multiple sectors rather than a single industry, and its listings are used both as pressure on the victim and as a signal to others.

Well-documented public accounts of the group describe the use of ransomware payloads, data exfiltration, and timed publication of material when negotiations stall or fail. None of that general pattern should be read as confirmed operational detail unique to the Koper Automatisering incident beyond what the leak-site claim itself states. For this case, the only specific assertion on record is the group’s own listing that internal files were taken and uploaded for public access.

Who is Koper Automatisering?

Koper Automatisering is described in the reported summary as a company that specialises in the development of specialised software for the food industry and floriculture. Organisations of this type typically build and support systems that help producers, processors, and related businesses manage production, logistics, inventory, quality, or commercial processes. They often hold contracts, technical documentation, customer and supplier records, and internal administrative files as a normal part of delivering and maintaining software.

A breach involving such a firm is consequential because the data it holds can touch multiple parties along a supply chain—employees, clients in food and horticulture, and partners—rather than only the software company itself. Even when the exact contents of a leak remain unconfirmed, the sector context explains why internal files matter: they can reveal business relationships, operational practices, and personal or commercial contact information that would not otherwise be public.

What was likely exposed

The facts name the exposed material as internal files exfiltrated in a ransomware attack. The group’s listing further claimed that documents were uploaded to public access and that “all files” were made available. No itemised inventory of data types—such as specific categories of personal data, financial records, or source code—has been disclosed in the available report. The number of people affected is unknown.

Organisations that develop specialised software for the food industry and floriculture commonly hold employee records, customer and supplier contact details, contracts, project documentation, and internal correspondence. Whether any or all of those categories were present in the material rhysida claimed to have published has not been independently confirmed. Readers should treat the exact contents as unconfirmed and rely only on the description given: internal files taken in a ransomware incident and asserted by the group to have been placed in public reach.

Why it matters

For individuals, the main risks are practical rather than abstract. Internal files can contain names, email addresses, phone numbers, job titles, and references to commercial relationships. That information can be used to craft convincing phishing messages, to impersonate colleagues or suppliers, or to support identity-related fraud. People who work at or with Koper Automatisering, or who appear in its client and partner records, may face elevated unwanted contact or social-engineering attempts for some time after a listing appears.

For the organisation, publication of internal material can disrupt operations, damage trust with customers in the food and floriculture sectors, and create ongoing legal and notification obligations depending on the jurisdictions involved and the nature of any personal data. Because the scale of affected individuals is unknown and the full file set is not publicly itemised in the facts, both the human and organisational impact remain partly unquantified. The absence of confirmed counts does not remove the need for caution; it simply means responses should be proportionate and based on what can be verified.

If your data was in this claimed breach

If you believe you may have been connected to Koper Automatisering as an employee, customer, or partner, a small number of concrete steps reduce immediate risk:

• Treat unexpected emails, calls, or messages that reference the company, its software, or the food and floriculture sectors with extra caution; verify through known channels before clicking links or sharing information.
• Change passwords on accounts that may have been used in relation to the firm, and enable multi-factor authentication where it is available.
• Monitor bank and relevant online accounts for unusual activity and consider fraud alerts if you have reason to think financial or identity data could have been involved.
• Retain any official notice you receive from the organisation and follow its instructions for support or credit monitoring if offered.
• Run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets.

Public detail on this incident remains limited to the June 2023 rhysida listing and the description of internal files. Further clarity, if it emerges, would come from the organisation or from official investigations rather than from the group’s own claims. Until then, calm verification and basic account hygiene are the most useful responses.
