Kim Knobbe, a Missouri business associate, has reported a breach to the federal health privacy portal affecting 11,927 people.
If you received a notice, here is what has been made public so far and what you can do about it.
Kim Knobbe’s Data Breach Investigation
Kim Knobbe is listed on the federal Office for Civil Rights breach portal as a business associate based in Missouri. According to that listing, the entity reported a breach affecting 11,927 individuals, and the submission is dated August 27, 2026. The portal classifies the incident as unauthorized access or disclosure, and it identifies the location of the breached information as a network server and other locations.
The public record for this incident is thin. The federal portal is a compliance listing, not a narrative account. It does not explain how the unauthorized access happened, who was responsible, when the activity began, or when it was discovered. It also does not list the specific types of personal or health information involved. This page does not guess at any of those details, and it will be more useful if the entity or a regulator publishes a fuller account.
The phrase business associate matters here. Under federal health privacy rules, a business associate is an organization that handles protected health information on behalf of a healthcare provider, health plan or similar covered entity. Examples include billing companies, record-storage vendors, software providers and other outside service firms. When a business associate is breached, the people affected are often patients who never dealt with that organization directly and may not even recognize its name. Their information reached it only because a doctor, hospital or insurer chose to use its services.
That is one reason notice letters in business associate breaches can arrive without warning. A person may receive a letter from a company they have never heard of, explaining that it held their records for a provider they did see. If you got a letter naming Kim Knobbe, or a letter from a healthcare provider that mentions this entity as a vendor, the notice is the best source of facts about what applies to you.
The count reported, 11,927, is the number given on the federal portal for this single filing. A filing like this is often the first public signal of an incident. More detailed notification letters to affected individuals can follow later, and they sometimes contain dates, data categories and details about protective services that the portal does not show. Anyone who is notified should read the letter closely and keep it, along with the envelope, for their records.
Why does unauthorized access to a network server matter? Servers commonly hold stored files, databases and shared documents, so access by someone who is not authorized can expose a large amount of information at once. In the healthcare setting, those records can include names, contact details, insurance information, billing data and treatment details. When such records are combined with a Social Security number or date of birth, they can be used for identity theft, and medical details can be used for medical identity theft, where someone uses another person’s coverage to obtain care or file false claims. Whether any of those categories apply in this incident is not stated in the listing.
Health data is also hard to replace once exposed. A password can be changed and a payment card can be reissued, but a diagnosis, a date of birth or a medical history cannot be reset. For that reason, the risk to people whose records were involved can last long after the first notice, and it is reasonable to stay alert for unfamiliar charges, unexpected explanation-of-benefits statements, and calls or messages that refer to a medical account or appointment.
A report to the federal government is also a sign that the entity concluded the event met the legal definition of a reportable breach. It is not, by itself, a finding about fault or about whether the safeguards in place were adequate. Those are questions that remain open on the public record, and they are the kind of questions that attorneys can ask on behalf of people who were harmed. Until more is published, the listing above is the reliable core of what is known.
When Did This Breach Occur?
The breach listing on the federal portal carries a submission date of August 27, 2026. That date is when the report was filed, not necessarily when the unauthorized access took place.
The listing does not state when the unauthorized access began, when it ended, or when it was discovered. If you received a notice, it may contain the dates that apply to you.
What Information Was Breached?
The federal portal does not list the specific categories of information involved. It says only that the incident was unauthorized access or disclosure and that the breached information was held on a network server and other locations.
Because the entity is a business associate, the records may relate to patients of one or more healthcare providers. The notice you receive, if any, is the best guide to what was exposed in your case.
