Monaco & Associates Incorporated has disclosed a cybersecurity incident that may have exposed sensitive personal and health-related details. This page summarizes what the company and federal records have reported so far.
Monaco & Associates’s Data Breach Investigation
Monaco & Associates Incorporated is a healthcare provider located in Kansas, according to the federal breach listing that tracks incidents of this kind. In a Notice of Data Security Incident posted on its website, the company said it experienced a cybersecurity incident that limited access to some of its computer systems on or around April 10, 2026. It said it started its incident response procedures right away, took steps to secure and contain the problem, brought in cybersecurity experts to investigate and notified law enforcement.
The company also said it stayed operational during this period and kept providing services on its regular schedule. That detail is useful context, because it suggests the attack did not shut the organization down, even though it reached files that held personal information about patients or clients.
The investigation produced two findings in sequence. On May 1, 2026, Monaco & Associates determined that some files belonging to a limited number of individuals may have been accessed by an unauthorized person. Then, on May 28, 2026, it determined what those files actually contained. According to the notice, the files held names, addresses, Social Security numbers and Medicaid ID numbers, and in some cases diagnostic and medication information.
The U.S. Department of Health and Human Services Office for Civil Rights lists the matter on its public breach portal. The entry was submitted on June 9, 2026 and reports that 534 individuals were affected. The portal classifies the incident as hacking or an IT incident and identifies a network server as the location of the breached information. The listing also shows that no business associate was involved, which means the filing was made by the provider itself rather than by an outside vendor handling data on its behalf.
Monaco & Associates said it has no evidence that the information has been misused and that it is informing people out of an abundance of caution. It said it has restored its systems, tightened its access controls and is evaluating additional technical safeguards. It also said it would mail letters over the following weeks to people whose information was identified as potentially affected, and that those letters would include complimentary credit monitoring and identity theft protection services, along with steps individuals can take to protect themselves. Questions can be sent to the email address given in the company’s notice.
The data types in this notice deserve attention. A Social Security number is the key piece of information used to open accounts, apply for loans and file tax returns, and it cannot easily be replaced. A Medicaid ID number is tied to a person’s public health coverage and can be used in medical identity theft, where someone obtains care, prescriptions or benefits under another person’s name. Diagnostic and medication details add a privacy dimension that goes beyond financial risk, because they reveal health conditions a person may never have chosen to share.
Healthcare providers of every size are frequent targets for network intrusions because their systems hold a combination of identity data and clinical data in one place. Smaller practices often have fewer dedicated security staff than large hospital systems, which can make it harder to detect and contain unauthorized access quickly. Under federal rules, a covered provider that experiences a reportable breach must notify affected individuals and the government, and the public listing is often the first place the scale of an incident becomes visible.
The company’s own description says the number of people involved is limited, and the federal listing puts that figure at 534. Whether a particular person is among them depends on which files were accessed, so receiving a letter is the most reliable signal. If you have been a patient or client of Monaco & Associates, you may want to watch your mail closely and keep any notice you receive.
When Did This Breach Occur?
Monaco & Associates reports that the incident began on or around April 10, 2026, when unauthorized activity limited access to some of its computer systems. On May 1, 2026, its investigation determined that some files may have been accessed by an unauthorized person, and on May 28, 2026 it determined which types of personal information those files contained.
The matter appeared on the HHS Office for Civil Rights breach portal with a submission date of June 9, 2026. The company said it would send notice letters by mail to potentially affected individuals over the following weeks.
What Information Was Breached?
According to Monaco & Associates, the files involved contained each person’s name, address, Social Security number and Medicaid ID number. In some cases the files also contained diagnostic and medication information.
The company has said it has no evidence that the information has been misused. Not every person will have had every type of data exposed, so the details in your own notice letter are the best guide to what applies to you.
