The Center for Kidney Care Data Breach

The Center for Kidney Care, P.C., a private medical practice based in Hainesport, New Jersey, was named on or around September 28, 2026 on the dark web leak site of the ransomware group known as Interlock. The group claims to possess approximately 40 gigabytes of data that it says includes patient information and records. As of this writing, The Center for Kidney Care has not publicly confirmed the alleged breach or its authenticity, and the scope of any actual compromise remains under investigation.

The Center for Kidney Care’s Data Breach Investigation

Attorneys are investigating the circumstances surrounding Interlock’s claim that it accessed and exfiltrated files from The Center for Kidney Care, which provides renal care services from locations in Hainesport and Burlington, New Jersey. A posting on a ransomware group’s leak site is the attacker’s own claim, published as leverage during extortion negotiations, and is not the same as an independently confirmed data breach. Healthcare providers are frequent targets of ransomware groups because medical records typically combine highly sensitive categories of information, including protected health information, insurance details, and other personal identifiers, that can be valuable both for extortion and for resale on dark web marketplaces.

Based on the nature of similar attacks against healthcare practices and Interlock’s own claims, the categories of information potentially at risk include patient names, health information such as treatment and diagnosis details, health insurance information, contact information, and other demographic and protected health information. Because The Center for Kidney Care has not yet confirmed which, if any, of these categories were actually accessed, patients should treat the claim seriously but not assume the worst until official confirmation is available. Investigators are monitoring for a formal notification from the practice, a regulatory filing with a state attorney general, or any other official acknowledgment that would move this from an unverified leak-site claim to a confirmed incident, and are examining what data security measures the practice had in place to protect patient records.

When Did This Breach Occur?

Interlock’s leak-site claim surfaced on or around September 28, 2026. The Center for Kidney Care has not disclosed when, or whether, unauthorized access to its systems actually occurred, nor has it confirmed the incident publicly.

What Information Was Breached?

The Center for Kidney Care has not confirmed the breach or specified what information was compromised. Based on Interlock’s claims and the nature of similar healthcare ransomware incidents, potentially affected information may include patient names, health information, health insurance information, contact information, and other demographic or protected health information, though none of this has been independently verified.
