UNM Health Shuts Clinics and Diverts Patients During Security Incident

5 de Novembro de 2026, 10:48

A cybersecurity incident forced UNM Health to divert ambulances, cancel appointments, and pause care while it contained the threat.

On Monday, October 26, the University of New Mexico Health System (UNM Health) faced the kind of security incident that healthcare leaders dread: one serious enough to change how patients could receive emergency care.

A major hospital network in New Mexico worked urgently on Monday to fix a cybersecurity problem. The issue forced it to send ambulances to other hospitals and left the state without a hospital emergency department able to treat the most serious injuries.

UNM Health operates New Mexico’s only Level 1 trauma center. These centers treat the most serious and complex injuries. Even a temporary closure can put extra pressure on other hospitals.

UNM Health runs New Mexico’s only Level 1 trauma center. That matters because a Level 1 center handles the most complex injuries, and losing even temporary access to it puts pressure on every nearby hospital.

The organization told patients not to come to its main Albuquerque hospital and canceled appointments across more than 30 clinics.

“The University of New Mexico Health System is experiencing a cybersecurity issue at this time. UNM Health officials are actively working to resolve this issue. Currently, all ambulance traffic is being diverted to other hospitals and all appointments at all clinics today have been cancelled. UNM Health patients should not show up to UNM Health facilities on October 26. Emergencies should be handled by 911 and non-emergencies should be delayed until further notice.” reads the update published by the organization on October 26, 2026. “The cybersecurity threat is affecting the entire University of New Mexico Health Sciences Center. “

UNM said its IT security teams identified the threat around 11 a.m. and began containment work. They later said the event affected some end-user devices but did not reach core systems or servers.

Leadership activated an Emergency Operations Center, brought in outside support, and notified state and federal law enforcement. That is the right sequence: isolate first, investigate second, communicate continuously.

From 12:30 to 2:30 p.m., UN Health temporarily stopped accepting new patients while teams protected the network. “System outages also required the suspension of outpatient surgeries and appointments for the remainder of the day.”

This was not an abstract IT problem. Patients arrived for care and were told to reschedule. Staff had to explain, repeatedly, why a hospital visit could not proceed as planned.

UNM also canceled classes at its Health Sciences Center and sent nonessential employees home. Medical, nursing, pharmacy, and population health students lost a day of instruction because the institution had to protect its network.

Other providers stepped in. Presbyterian Healthcare Services and Lovelace Health System coordinated with UNM and took additional patients, which is exactly what a functioning regional healthcare system should do.

UNM Health began restoring its systems on Monday afternoon. By the following day, hospitals, ambulance services and clinics were back to normal.

The incident is still under criminal investigation. Employees reported messages claiming that patient, student and staff data had been stolen, but UNM has not confirmed this. The hospital also warned people to watch out for phishing and fraud attempts by attackers exploiting the incident.

McKesson confirms cyber incident after ShinyHunters claims patient-data theft

31 de Agosto de 2026, 11:46

Healthcare and pharmaceutical-distribution giant McKesson has disclosed a cybersecurity incident involving unauthorized access to third-party applications and the theft of data.

McKesson Corporation is an American healthcare company that distributes pharmaceuticals and provides medical supplies, health information technology, and care management tools.

McKesson says it discovered the cybersecurity incident on August 25, 2026, and that its investigation is still in early stages.

“Based on our investigation thus far, including assessments by leading cybersecurity industry experts supporting our response, we’ve confirmed that the unauthorized access to certain third-party applications and the exfiltration of certain data was associated with a subset of customers within our Oncology & Multispecialty and Medical-Surgical business units.”

For now, McKesson provides no information about the amount or nature of the stolen data.

The attack has been claimed by ransomware/extortion group Shiny Hunters. On their leak site the group claims to have stolen hundreds of millions of records containing very sensitive information spanning from Personally Identifiable Information (PII) to Protected Health Information (PHI).

The ShinyHunters extortion group told BleepingComputer that it was behind the attack, claiming it gained access after conducting voice phishing (or vishing) attacks—a form of social engineering—against multiple McKesson employees. Subsequently, the group said it used compromised Okta single-sign-on accounts to access Salesforce and Snowflake environments. It further claimed to have removed approximately 1 TB of data between August 21 and 25.

The group also said the data includes roughly 284 million records, which does not necessarily mean they belong to 284 million unique patients.

A combination of identity information and healthcare-related details could make affected people targets for convincing scams. Criminals could impersonate a pharmacy, insurer, medical provider, debt collector, or patient-support service and use personal details to make the approach appear legitimate.

Healthcare data is especially useful in social-engineering attacks because it can be used to create a sense of urgency: Criminals could scare a target by sending a supposed prescription problem, unpaid claim, delivery issue, appointment change, or request to “verify” insurance details. At this stage, however, McKesson has not confirmed that any particular category of patient data was accessed.

What to do if you’re affected

While waiting for more information about the nature of the breach and how you might be affected, there are a few things you can do:

  • Check the company’s advice. Every breach is different, so check with the company to find out what’s happened and follow any specific advice it offers.
  • Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
  • Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop, or phone as your second factor. Some forms of 2FA can be phished just as easily as a password, but 2FA that relies on a FIDO2 device can’t be phished.
  • Watch out for impersonators. Cybercriminals may contact you posing as the breached company. Check its official website to see if it’s contacting victims, and verify the identity of anyone who contacts you using a different communication channel.
  • Take your time. Phishing attacks often impersonate people or brands you know and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
  • Consider not storing your card details. It’s definitely more convenient to let sites remember your card details, but it increases the risk if a company suffers a breach.
  • Set up identity monitoring. This can alert you if your personal information is found being traded illegally online and help you recover afterward.

Let’s face it, an incognito window can only do so much. 
 
Breaches, dark web trading, credit fraud. Malwarebytes Identity Theft Protection monitors for all of it, alerts you fast, and comes with identity theft insurance.
