Disclosure context

About global

The "global" ransomware group is a relatively new threat actor that emerged in June 2025, operating with primarily financial motivations based on their ransomware deployment activities. Due to the group's recent emergence and limited public documentation from major cybersecurity organizations, specific details about their country of origin, affiliations, and operational structure remain unclear, though their targeting patterns suggest broad international scope. Based on available data, the group has compromised 32 known victims across multiple countries including the United States, Australia, Brazil, Great Britain, and Mexico, with their attacks primarily focused on healthcare, manufacturing, technology, and public sector organizations. The group's attack methodology, encryption techniques, and specific tools remain undocumented in publicly available threat intelligence reports from established security research organizations. Given the limited timeframe since their first observed activity in June 2025, there are no widely reported major campaigns or high-profile incidents attributed to this group in public threat intelligence sources. The current operational status of the "global" ransomware group remains active based on their recent emergence, though comprehensive analysis is limited due to the lack of detailed public reporting from major cybersecurity firms and government agencies. The group has been linked to 36 public disclosures across our corpus. First observed on a leak site on June 4, 2025; most recent post August 28, 2026. The operation is currently inactive.

If your organisation is affected

A listing by global means Hangzhou Qihan Biotech Co., Ltd. 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 global'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.
