Attack summary

Severity: high — Medical records and personal health information from a healthcare provider constitute regulated/sensitive PII at scale. Although no proof files have yet been published, the 20 GB volume and confirmed exfiltration claim, combined with healthcare sector sensitivity, warrant high severity.

The Qiulong group claims to have exfiltrated approximately 20 GB of data from the practice. The group accuses the doctor of failing to protect patient privacy and states that data will be published soon, though no specific sample or proof has yet been disclosed.

Disclosure context

About Qiulong

Qiulong is an emerging ransomware group that first appeared in April 2024, operating with apparent financial motivations based on their targeting patterns and limited observed activities. The group's origin and affiliations remain largely unknown due to their recent emergence and relatively small operational footprint, with no publicly documented evidence from major security firms or law enforcement agencies regarding their geographical base or connections to other cybercriminal organizations. Limited public reporting suggests the group employs standard ransomware deployment techniques, though specific initial access vectors, encryption methods, and whether they engage in data exfiltration or double extortion tactics have not been extensively documented by major threat intelligence providers. Their operations have remained relatively low-profile compared to established ransomware families, with approximately eight known victims primarily concentrated in Brazil and Canada, showing a particular focus on healthcare and business services sectors. The group appears to remain active as of late 2024, though their limited operational scope and recent emergence mean they have not yet attracted significant law enforcement attention or disruption efforts. The group has been linked to 8 public disclosures across our corpus. First observed on a leak site on April 22, 2024; most recent post June 24, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Qiulong means www.drwilliansegalin.com.br 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, CERT.br (Brazil), as required for your jurisdiction.
  • Monitor for the data appearing on Qiulong'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.
