University of Mississippi Medical Center’s Data Breach Investigation
On February 19, 2026, UMMC experienced a significant cyberattack that compromised its IT systems, including its electronic medical records system. This disruption forced the closure of all 35 UMMC clinics across the state, and a number of outpatient surgeries, procedures, and imaging appointments were cancelled. The hospital, which serves more than 70,000 patients annually, took immediate action by shutting down its IT systems as a precautionary measure.
The attackers have reportedly made contact with the hospital, and UMMC is working closely with law enforcement authorities, including the FBI, US Homeland Security, and the US Cybersecurity and Infrastructure Security Agency, to determine the full scope of the attack and identify the perpetrators.
While UMMC officials have not disclosed what specific information was compromised, the hospital is working diligently to restore its systems and services. Affected individuals are advised to monitor their accounts for any unusual activity and take steps to protect their personal information.
When Did This Breach Occur?
The cyberattack took place on February 19, 2026, affecting UMMC’s IT systems. The breach led to the closure of clinics and the cancellation of elective procedures. Services for patients currently at UMMC are continuing with “downtime procedures,” while efforts are underway to resolve the situation. The disruption is expected to last for several days.
What Information Was Breached?
No specific details have been released regarding the exact nature of the data involved in the breach. However, the disruption to UMMC’s electronic medical records system raises concerns about the potential exposure of sensitive personal and medical information, including patient records.
UMMC officials have not confirmed whether personally identifiable information (PII), medical records, or financial data was compromised. Affected individuals are encouraged to remain vigilant and report any suspicious activity, particularly regarding unauthorized charges on bank or credit accounts.
What You Can Do
If you believe your personal or medical information may have been compromised in the UMMC cyberattack, consider taking the following actions to protect yourself:
-
Monitor Your Bank Accounts: Regularly check your bank and credit card statements for any unusual or unauthorized charges. If you detect any suspicious transactions, contact your bank immediately.
-
Check Your Credit Reports: You are entitled to a free credit report each year from the three major credit bureaus: TransUnion, Experian, and Equifax. Check your reports for signs of fraudulent activity or accounts opened in your name.
-
Place a Fraud Alert or Credit Freeze: To prevent further misuse of your personal information, consider placing a fraud alert or credit freeze on your credit reports. A fraud alert requires creditors to verify your identity before approving new accounts, while a credit freeze prevents access to your credit report altogether.
-
Report Suspicious Activity: If you suspect identity theft or fraudulent activity, immediately report it to your financial institution and local law enforcement authorities.
