Allervie Health Breach

In late 2025, AllerVie Health, a Frisco, Texas-based network of allergy and asthma clinics, suffered a significant data breach following unauthorized network access between October 24 and November 3, 2025. While initial reports cited a general compromise of patient records, subsequent analysis of the leaked data-attributed to the Anubis ransomware group-reveals a much broader scope of exposure than first estimated. A detailed parse of the compromised dataset via databreach.com indicates that the leak affects tens of thousands of individuals, specifically exposing 122,700 unique email addresses, 58,900 unique phone numbers, and, most critically, 15,200 unique Social Security numbers.
