Studiosus Reisen Munchen Listed by coinbasecartel Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Studiosus Reisen Munchen was listed today by the coinbasecartel ransomware group, which claims to have stolen internal files. Anyone who has provided personal data to the company should review the group’s claims and take appropriate protective steps.
What happened
Studiosus Reisen Munchen was listed by the coinbasecartel ransomware group on or around March 30, 2026. The listing states that internal files were exfiltrated during a ransomware attack. No confirmed count of affected people, no timeline for the intrusion itself, and no verified details on the method of access have been made public.
The group behind it: coinbasecartel
The coinbasecartel group is known for targeting organisations and posting claims of access on leak sites. In this case the group claims responsibility for the Studiosus Reisen Munchen incident through its listing. Public records of the actor show a pattern of ransomware operations that include data exfiltration followed by public disclosure when ransom demands are not met; independent confirmation of the current claim has not been reported.
About Studiosus Reisen Munchen
Studiosus Reisen Munchen is a Munich-based tour operator that organises cultural and study tours to more than 100 countries. Companies of this type routinely collect customer names, contact details, passport information, payment records and health or dietary data required for travel arrangements, as well as internal operational documents. A breach at such an organisation can therefore involve both customer records and business files that support international itineraries.
What was likely exposed
The only data category named in connection with the incident is internal files exfiltrated during a ransomware attack. The precise contents of those files have not been disclosed. Organisations in the travel sector commonly store customer booking information, identity documents and financial details, yet the exact data types involved here remain unconfirmed.
- Monitor official statements from Studiosus Reisen Munchen for any further disclosure.
- Review personal banking and travel accounts for unusual activity.
- Consider placing fraud alerts with credit agencies if passport or payment data could be involved.
Why it matters
Travel companies hold data that can be used for identity verification or financial transactions. When internal files are removed, affected individuals may encounter risks of fraud or targeted scams even if the total number of records remains unknown. For the organisation, the incident adds operational and regulatory burdens typical of ransomware events in the European tourism sector.

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.
