Quest Healthcare Solutions, which also operates as Quest Health Solutions, experienced a data breach following a ransomware attack by the Anubis group. The attack was estimated to have occurred on June 24, 2026, and was discovered by the company on July 2, 2026. As of July 3, 2026, the company has not issued a public statement or official breach notification letter, and regulators have not been notified.
Preliminary reports indicate that the breach may have exposed various types of sensitive information, including names, Social Security numbers, dates of birth, addresses, phone numbers, health insurance information, medical information, patient records, treatment data, and billing data. Employee data and internal company files were also reportedly compromised. The exact number of affected individuals and the total volume of compromised data are still under investigation.
This incident involves Quest Healthcare Solutions, a patient care provider, and should not be confused with Quest Diagnostics (NYSE: DGX) or DentaQuest. The company is a vendor of diabetes and insulin supplies, as well as continuous glucose monitors. Due to this vendor relationship, the breach likely impacts downstream healthcare providers and their patients. Patients who received these supplies from Quest Healthcare Solutions should monitor for identity theft and consider credit freezes.
