Aldaco Avance 2022 S.L. Listed by Deadlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Aldaco Avance 2022 S.L. was listed by the Deadlock Ransomware Group on July 12, 2026, in a listing claiming internal files were exfiltrated in a ransomware attack. Affected individuals should check for any notices from the company and change passwords or monitor their accounts if they have shared data with it.
What happened
The only confirmed information is the listing itself. Deadlock claims responsibility for a ransomware operation against the company that resulted in the removal of internal files. No independent confirmation of the breach, the volume of data, or the method of access has been released. The date the files were taken and whether any systems were encrypted remain undisclosed.
Who is Deadlock?
Deadlock is a ransomware group that publishes victim names on a dedicated leak site when ransom demands are not met. The group follows the common pattern of exfiltrating data before encryption and using the threat of publication to pressure targets. Its listings are presented by the group as evidence of successful operations, though the accuracy of each claim is assessed case by case.
Aldaco Avance 2022 S.L. and its sector

It maintains operations in Asturias, Galicia and Madrid and supplies machinery, technical tools and specialised advisory services for professional projects.

What was likely exposed
The listing states that internal files were exfiltrated. No inventory of specific file types or data categories has been published. Companies of this kind commonly store employee records, client and supplier contact details, project specifications and financial documentation, but the precise contents of the exfiltrated material have not been confirmed.
What's at stake
Exposure of internal files can lead to the disclosure of personal information belonging to employees or clients, as well as details of ongoing projects and commercial relationships. For the organisation, the incident may affect contractual obligations and regulatory compliance requirements under Spanish and European data-protection rules. Individuals named in the files face the standard risks associated with the circulation of business records, including potential misuse of contact or identification data.
What to do if you're exposed

Publicly posted by deadlock — 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.
