La ville de Ouangani Listed by Deadlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
La ville de Ouangani was listed by the Deadlock Ransomware Group on July 10, 2026 after internal files were exfiltrated in a ransomware attack; the number of people affected is currently unknown. Residents and employees should check whether their information was exposed and take appropriate protective steps.
Inside the incident
The incident involves a claim by the Deadlock group that it carried out a ransomware operation against the municipality and removed internal files. No date for the initial intrusion or the attack itself has been made public. The scale of the operation, including the volume of data or systems affected, also remains undisclosed in available reports.
Who is Deadlock?
Deadlock is a ransomware group that has appeared in public listings of claimed victims. Such groups commonly use encryption to disrupt operations while also removing data from targeted networks. They frequently post claims and sample files on dedicated leak sites to pressure victims. Prior public reporting on the group has documented similar listings against other organisations, though each claim requires independent verification.
About La ville de Ouangani
La ville de Ouangani is a municipal government serving residents of Ouangani, located in the French overseas department of Mayotte. Local authorities of this type manage public services such as civil records, local taxation, urban planning, and social assistance. They routinely process data on residents, employees, and administrative functions.
The information in question
The Deadlock listing refers to internal files removed during the attack. No further breakdown of file categories or specific data fields has been released. Municipalities routinely hold records that can include personal identifiers, contact details, financial information, and operational documents, but the exact contents in this case are unconfirmed.
The real-world impact
Exposure of internal municipal files can create risks of misuse for identity-related fraud or targeted scams if personal data is present. The organisation may face operational disruption while restoring systems and reviewing security. Residents whose information appears in the files have no confirmed timeline for notification or remediation steps.
What to do if you're exposed
Individuals concerned about possible exposure should monitor their financial accounts and official correspondence for unusual activity. Changing passwords for any linked services and enabling multi-factor authentication where available are standard initial measures. Readers can run a free exposure scan of their email address to check whether their information has appeared in known breach data.

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.
