dosocho.es Listed by m3rx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
dosocho.es was listed by the m3rx ransomware group on May 17, 2026, after internal files were exfiltrated in a ransomware attack. Individuals connected to the organisation should check whether their information was involved and take steps to protect their accounts.
What happened
The listing indicates that internal files were taken during a ransomware operation targeting Recambios Generales del Automóvil Dosocho S.L. The reported volume stands at 50 GB across 28,000 files. No further details on the intrusion method, encryption of systems, or ransom demands have been disclosed publicly. The exact date of the data access remains unknown.
The group behind it: m3rx
m3rx is a ransomware group that has appeared in multiple incidents involving data exfiltration followed by listings on dedicated leak sites. Such groups commonly encrypt victim systems and threaten to release stolen material if demands are not met. The current case rests on the group's own claim of responsibility; independent confirmation of the data's authenticity or the group's direct involvement has not been established in available reports.
About dosocho.es
Recambios Generales del Automóvil Dosocho S.L. operates from Madrid and runs e-commerce platforms, including dosochoauto.es, that sell new automotive spare parts and accessories. Companies in this sector routinely maintain records related to customer orders, supplier transactions, inventory, and internal business operations. A breach at such a firm can expose both commercial information and any personal data collected from clients or partners.
What was likely exposed
The facts released so far describe the removal of internal files totaling 50 GB and 28,000 items. No specific categories of data, such as customer names, payment details, or employee records, have been confirmed. Organizations of this type typically store order histories, contact information, and financial documents, yet the precise contents of the exfiltrated material remain unverified beyond the stated volume and file count.
Why it matters
Exposure of internal files can create operational risks for the company and potential privacy concerns for any individuals whose information appears in those files. Without a confirmed inventory of the data, the scope of downstream effects, such as identity misuse or targeted fraud, cannot be quantified. The incident also highlights the continued targeting of mid-sized commercial entities that hold transactional records.
If your data was in this claimed breach
Monitor accounts associated with any orders placed through dosocho.es or related sites for unusual activity. Enable multi-factor authentication where available and review bank or payment statements for unauthorized charges. Individuals can run a free exposure scan of their email address against known breach datasets to check for prior appearances of their information.

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.
