CRPxO is a ransomware group first observed in July 2026 with a primary financial motivation, having claimed six known victims to date with a notable focus on the healthcare sector across the United States and China. Due to the group's recent emergence and limited public footprint, comprehensive technical attribution and operational details have not yet been documented by CISA, the FBI, Mandiant, or other reputable threat intelligence sources. Based on available victimology data, the group demonstrates a deliberate targeting pattern favoring healthcare organizations in the US and CN, a sector frequently selected for its sensitivity to operational disruption and willingness to pay ransoms to restore critical services. No confirmed country of origin, RaaS affiliation, specific tooling, or extortion methodology has been publicly attributed to CRPxO at this time, and the group's infrastructure, encryption methods, and initial access vectors remain uncharacterized in open-source reporting. With only six known victims and a short operational history, CRPxO should be considered an emerging and actively monitored threat, though its current operational status and potential for escalation or rebranding cannot be confirmed based on publicly available intelligence. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on July 9, 2026. The operation is currently active.

If your organisation is affected
A listing by CRPxO means Creative Smiles Pediatric Dentistry 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 CRPxO'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.
