The Argonauts ransomware group is a recently emerged threat actor that began operations in November 2024, appearing to be financially motivated based on their ransomware deployment patterns. Given their recent emergence and limited public reporting, specific details about their country of origin, affiliations, and operational model remain largely undocumented by major threat intelligence firms and law enforcement agencies. Based on observed targeting patterns, the group appears to focus on opportunistic attacks across multiple sectors, with their 13 known victims spanning technology, manufacturing, transportation and logistics, business services, and healthcare organizations primarily located in Italy, Taiwan, the United States, Japan, and Canada. The group's attack methodology, encryption techniques, and whether they employ double or triple extortion tactics have not been extensively documented in publicly available threat intelligence reports from established security research organizations. No major high-profile campaigns or significant law enforcement actions against Argonauts have been reported in open sources as of early 2024. The group appears to remain active as of the most recent threat intelligence reporting, though their limited operational history and low victim count suggest they are either a newly formed operation or a relatively small-scale threat actor. The group has been linked to 13 public disclosures across our corpus. First observed on a leak site on November 27, 2024; most recent post December 16, 2024. The operation is currently inactive.

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.
