Chaos Ransomware Claim Against Ohio Primary Care Network Remains Unconfirmed
Third-party threat intelligence sources allege the Chaos ransomware group breached Central Ohio Primary Care around August 25–26, 2026, with estimated data exfiltration figures ranging from 263 GB to 362 GB, but COPCP has issued no public acknowledgment and no matching filing appears on the HHS breach portal or with Ohio regulators. A law firm announced a data-privacy investigation on August 27, though no lawsuit has been filed. Until COPCP issues an incident notice, a regulatory filing appears, or a court complaint is submitted, the breach's scope, affected systems, and patient impact remain unverified.
