Disclosure context

About hunters

Hunters International is a ransomware group first observed in October 2023 that operates with primary financial motivations, having claimed responsibility for attacks against at least 307 known victims across a broad range of sectors and geographies. The group is believed to have acquired the source code and infrastructure of the defunct Hive ransomware operation following Hive's disruption by law enforcement in January 2023, though Hunters International has publicly disputed characterizations that it is a direct Hive rebrand, asserting instead that it independently purchased the codebase; the group operates as a Ransomware-as-a-Service model, recruiting affiliates to conduct intrusions on its behalf. Hunters International employs double extortion tactics, exfiltrating victim data prior to encryption and threatening public release on a dedicated leak site to increase pressure on victims to pay; initial access vectors observed across reported incidents include phishing, exploitation of publicly exposed remote services, and credential abuse, with the group deploying its Rust-based encryptor derived from Hive's codebase. The group has demonstrated a notably indiscriminate targeting pattern, with victims concentrated in the United States, United Kingdom, Canada, France, and Germany spanning Business Services, Manufacturing, Technology, Healthcare, and Energy sectors, reflecting a financially opportunistic rather than strategically selective approach; no single landmark ransom payment or named high-profile campaign has been singularly attributed to the group in major public reporting as of available documentation. As of the most recent publicly available threat intelligence reporting, Hunters International remains an active and operational ransomware threat with a growing victim count and no confirmed law enforcement disruption or rebranding. The group has been linked to 307 public disclosures across our corpus. First observed on a leak site on October 20, 2023; most recent post May 27, 2025. The operation is currently inactive.

If your organisation is affected

A listing by hunters means Archetype Group 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.
Monitor for the data appearing on hunters'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.
