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 410 public disclosures across our corpus. First observed on a leak site on July 29, 2024; most recent post May 10, 2026. The operation is currently active.
