Disclosure context

About Lynx

Lynx is a relatively new ransomware group that emerged in July 2024, operating with apparent financial motivations and demonstrating rapid scaling capabilities with 397 documented victims within their first few months of operation. The group's origin and specific affiliations remain unclear due to their recent emergence, though their targeting patterns suggest a sophisticated operation that may operate independently rather than as a traditional Ransomware-as-a-Service model. Based on their victim distribution, Lynx appears to employ broad-spectrum targeting methodologies focusing heavily on English-speaking countries, with the United States, United Kingdom, Canada, Germany, and Australia representing their primary geographic targets, while concentrating their attacks on manufacturing, business services, technology, and transportation/logistics sectors, though specific technical details regarding their initial access vectors, encryption methods, and data exfiltration practices have not yet been extensively documented by major security research organizations. Due to the group's recent emergence, there are no widely reported major campaigns or high-profile incidents that have gained significant public attention from law enforcement agencies or established threat intelligence firms. As of late 2024, Lynx appears to remain active with no reported law enforcement disruptions or operational changes. The group has been linked to 414 public disclosures across our corpus. First observed on a leak site on July 29, 2024; most recent post June 18, 2026. The operation is currently active.

If your organisation is affected

A listing by Lynx means www.ville-dunkerque.fr appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CERT-FR (France), as required for your jurisdiction.
Monitor for the data appearing on Lynx's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
