Disclosure context

About shinyhunters

Based on the limited publicly available information, shinyhunters appears to be a recently emerged ransomware group first observed in October 2025, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's origin and potential affiliations remain unclear due to their recent emergence, and there is insufficient public documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and specific technical capabilities have not been extensively documented by major threat intelligence firms, though their targeting pattern suggests a broad opportunistic approach rather than sector-specific specialization. The group has reportedly victimized approximately 77 organizations, with primary targeting focused on the United States, France, Japan, Germany, and Australia, showing particular interest in consumer services, technology, financial services, transportation and logistics, and education sectors. Given the group's very recent emergence in late 2025, there are no widely reported major campaigns or high-profile incidents documented by established security research organizations, and no known law enforcement actions have been publicly reported against this group. The current operational status of shinyhunters remains active based on available reporting, though comprehensive threat intelligence profiles from major security firms like Mandiant, CrowdStrike, or government agencies have not yet been published due to the group's recent appearance in the threat landscape. The group has been linked to 134 public disclosures across our corpus. First observed on a leak site on October 3, 2025; most recent post June 18, 2026. The operation is currently active.

If your organisation is affected

A listing by shinyhunters means Amazon owned OneMedical.com 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 shinyhunters'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.
