ACU Listed by Deadlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
ACU was listed by the Deadlock ransomware group on July 10, 2026, following a ransomware attack in which internal files were exfiltrated. Anyone connected to the organization should check for official notifications and take steps to protect their information.
What happened
On July 10, 2026, the Deadlock ransomware group listed the Automobile Club of Uruguay on its leak site. The listing states that internal files were exfiltrated during a ransomware attack. No further details on the timing of the intrusion, the volume of data, or the method of access have been disclosed.
The group behind it: Deadlock
Deadlock is a ransomware operation that targets organizations and publishes claims of stolen data on a dedicated leak site when ransom demands are not met. Such groups typically encrypt systems and threaten to release exfiltrated material to pressure victims. The listing of ACU constitutes the group’s claim; independent confirmation of the data’s authenticity or scope has not been reported.
Who is ACU?
The Automobile Club of Uruguay is a nonprofit organization that provides roadside assistance, vehicle inspections, travel planning, and tourism services to motorists. It operates in the automotive and transportation sector and maintains affiliations with international automobile networks. Organizations of this type routinely collect member details, payment information, and operational records to deliver their services.
The information in question
The only data category named in connection with the incident is internal files exfiltrated during the ransomware attack. The exact types of records contained in those files have not been disclosed. Organizations in this sector commonly hold member contact information, vehicle registration data, insurance details, and financial transaction records, but whether any of these categories are present remains unconfirmed.
The real-world impact
Exposure of internal files can create risks of identity misuse or fraud if personal or financial details are included. For the organization, the incident may lead to operational disruption and costs associated with investigation and remediation. Because the scale of affected individuals and the specific data elements remain unknown, the full extent of consequences cannot yet be assessed.
If your data was in this breach

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.
