Attack summary

Severity: critical — Confirmed exfiltration of highly regulated medical and PII data at large scale: 167,303 patients with SSNs, full contact details, and sensitive protected health information (PHI) including mental health, substance abuse, STI, and cancer diagnoses — categories afforded heightened legal protection under HIPAA and 42 CFR Part 2. The inclusion of public figures and the volume of SSNs further elevates risk.

LeakBazaar claims to have exfiltrated a full patient database containing records for 167,303 patients, including Social Security Numbers, addresses, phone numbers, emails, ICD-10 diagnoses, medications, and pathology reports with narrative text, and states the data is for sale. The group specifically highlights 49,798 patients with sensitive diagnoses (mental health, substance use, STIs, cancer, Hepatitis C) and notes the presence of notable public figures among the records.

Disclosure context

About LeakBazaar

Based on available public reporting, LeakBazaar is a relatively new ransomware group that first emerged in May 2026, appearing to be financially motivated given their targeting of high-value sectors and geographic focus on developed economies. The group's country of origin and potential affiliations with other cybercriminal organizations remain unknown at this time, and there is insufficient public documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. With only nine documented victims since their emergence, LeakBazaar demonstrates a targeted approach focusing primarily on manufacturing, technology, business services, transportation/logistics, and financial services sectors across the United States, India, Singapore, and the United Kingdom, though their specific initial access vectors, encryption methods, and whether they employ double or triple extortion tactics have not been publicly documented by major threat intelligence firms or law enforcement agencies. Due to the group's recent emergence and limited public reporting from established sources such as CISA, FBI, or Mandiant, there are no widely reported notable campaigns or high-profile attacks that have gained significant attention in the cybersecurity community. LeakBazaar appears to remain active as of current reporting, though the limited intelligence available makes it difficult to assess their operational tempo or expansion plans. The group has been linked to 9 public disclosures across our corpus. First observed on a leak site on May 10, 2026. The operation is currently active.

If your organisation is affected

A listing by LeakBazaar means Gastroenterology & Hepatology 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 LeakBazaar'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.
