ROC Mondriaan Listed by vicesociety Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The ROC Mondriaan Listed by vicesociety Ransomware Group (reported January 6, 2022) 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.
On January 6, 2022, the ransomware group vicesociety listed ROC Mondriaan on its data-leak site. The listing states that internal files were taken during a ransomware operation; no further details on the volume of data, the number of individuals affected, or the precise timing of the intrusion have been made public.
The incident is one of many in which educational institutions appear on ransomware leak sites. Because the organisation holds records on students, staff and operational activities, any confirmed exposure of internal material carries implications for privacy and institutional continuity that extend beyond the immediate technical event.
What happened
ROC Mondriaan was added to the vicesociety ransomware leak site on 6 January 2022. The group claims to have exfiltrated internal files during a ransomware attack. No independent confirmation of the data theft or its scope has been released by the organisation or by investigators. The number of people whose information may be involved remains unknown, and the method of initial access has not been disclosed.
Who is vicesociety?
Vicesociety is a ransomware operator that follows a double-extortion model: it encrypts systems and also removes data, then publishes file listings on a dedicated leak site when a ransom demand is not met. The group has appeared in multiple public reports since 2021, typically targeting mid-sized organisations across several sectors. Its listings constitute claims by the actor; verification of the underlying incidents rests with the affected organisations and law-enforcement investigations.
About ROC Mondriaan
ROC Mondriaan is a regional vocational-education provider in the Netherlands. Institutions of this type maintain student enrolment records, academic histories, staff employment files and administrative systems required for day-to-day operations. A breach at such an organisation can therefore involve personal data of current and former students as well as internal communications and planning documents.
What was likely exposed
The only data category named in connection with the listing is “internal files exfiltrated in ransomware attack.” No inventory of specific file types, databases or record categories has been published. While organisations in the vocational-education sector routinely hold student identifiers, contact details, assessment records and personnel files, the exact contents of any material allegedly taken from ROC Mondriaan have not been confirmed.
Why it matters
Exposure of internal files can place personal information of students and staff at risk of further misuse, including identity-related fraud or targeted scams. For the institution, the event may require extended forensic review, notification obligations under Dutch and European data-protection rules, and measures to restore operational systems. The absence of Reported Details on scale leaves the full extent of these consequences undetermined at present.
If your data was in this claimed breach
Individuals who believe their information may have been held by ROC Mondriaan should monitor official communications from the organisation and from Dutch data-protection authorities. Practical first steps include changing passwords for any accounts linked to the institution, enabling multi-factor authentication, and watching for unusual activity on financial or government-service accounts. Readers can also run a free exposure scan of their email address against known breach data sets to check for prior appearances in public listings.

Publicly posted by vicesociety — 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.
