Disclosure context

About Daixin

Daixin is a ransomware group that emerged in August 2022, operating with primarily financial motivations and demonstrating a particular focus on critical infrastructure sectors. The group's origin and specific affiliations remain unclear from publicly documented sources, though their targeting patterns suggest sophisticated operational capabilities and potential access to healthcare sector vulnerabilities. Daixin employs typical ransomware attack methodologies including data exfiltration prior to encryption, implementing double extortion tactics to pressure victims into payment by threatening to release stolen sensitive information alongside system encryption. The group has demonstrated a pronounced targeting preference for healthcare organizations, which represents a significant portion of their documented victims, alongside government entities and financial services organizations. Their geographic focus centers heavily on the United States while also targeting victims across Indonesia, the United Arab Emirates, Germany, and Canada, indicating either broad operational reach or collaboration with regional affiliates. With 21 documented victims since their emergence, Daixin represents a relatively newer but active threat actor in the ransomware landscape. Current intelligence suggests the group remains operationally active as of recent assessments, continuing to pose threats to critical infrastructure sectors, particularly healthcare organizations that may be viewed as high-value targets due to the sensitive nature of their data and operational dependencies. The group has been linked to 21 public disclosures across our corpus. First observed on a leak site on August 3, 2022; most recent post September 11, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Daixin means OakBend Medical 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, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on Daixin'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.
