Top Notch Dentistry of Dallas Data Breach

Top Notch Dentistry of Dallas, a healthcare provider based in the United States, was identified as a victim by the CRPxO ransomware group on July 9, 2026. This listing was discovered via SOCRadar’s Dark Web Monitoring service. The organization is a dental practice located in the Dallas area and appears to be part of a broader campaign by CRPxO targeting dental and healthcare providers, with several similar victims identified concurrently.

SOCRadar’s threat intelligence did not find direct evidence of Top Notch Dentistry’s domain in stealer logs monitored in the 60 days prior to the listing. However, this absence of evidence does not confirm the absence of a breach, as credentials could have been obtained through other means, such as personal email aliases, or the logs may have been rotated before indexing. Ransomware groups like CRPxO commonly use credentials harvested from infostealer logs to gain initial access to victim systems, often leveraging compromised Microsoft 365, VPN, or remote-access portals. Given the nature of such attacks, continued monitoring and proactive credential hygiene are recommended for organizations in this sector.
