PET Imaging of Northern Colorado Email Breach Affects 4,824 Patients

PET Imaging of Northern Colorado, a healthcare provider in Colorado, has reported a significant data breach to the U.S. Department of Health and Human Services (HHS) affecting 4,824 individuals. The incident, which involved unauthorized access to the organization's email systems, highlights the ongoing cybersecurity challenges facing healthcare providers across the nation.

What Happened

On June 27, 2025, PET Imaging of Northern Colorado filed a breach notification with the HHS Office for Civil Rights, reporting a hacking/IT incident that compromised their email systems containing protected health information (PHI). The breach originated from a cyberattack targeting the organization's network infrastructure, specifically focusing on their email communications.

The incident represents another example of cybercriminals targeting healthcare organizations' email systems, which often contain sensitive patient information including medical records, treatment details, and personal identifiers. Email systems have become increasingly attractive targets for cybercriminals due to the wealth of information they contain and their critical role in healthcare operations.

Strauss Borrelli PLLC, a leading data breach law firm, has announced they are investigating the incident on behalf of affected patients, indicating the potential for legal action related to the breach.

Who Is Affected

The breach impacted approximately 4,824 individuals who were patients or had interactions with PET Imaging of Northern Colorado. These affected individuals likely had their protected health information stored in the compromised email systems.

PET Imaging of Northern Colorado specializes in positron emission tomography (PET) scans, a type of medical imaging that helps doctors diagnose and monitor various conditions including cancer, heart disease, and neurological disorders. Patients who received services from the facility may have had sensitive medical information compromised, including:

• Personal identifying information (names, addresses, phone numbers)
• Medical record numbers and patient IDs
• Insurance information and billing details
• Medical diagnoses and treatment information
• PET scan results and imaging reports
• Physician notes and referral information

Breach Details

According to the notification filed with HHS, the breach was classified as a "Hacking/IT Incident" with the location specified as email systems. This classification indicates that cybercriminals gained unauthorized access to PET Imaging of Northern Colorado's digital infrastructure through technical means.

Email-based breaches in healthcare settings typically occur through several attack vectors:

• Phishing attacks: Cybercriminals send deceptive emails to trick employees into revealing credentials or installing malware
• Business Email Compromise (BEC): Attackers gain access to legitimate email accounts to conduct fraudulent activities
• Ransomware: Malicious software encrypts systems and demands payment for restoration
• Credential stuffing: Using stolen username and password combinations to access accounts

While the specific attack method used against PET Imaging of Northern Colorado has not been disclosed, the email system compromise suggests that patient communications, appointment scheduling, and medical record exchanges may have been accessed by unauthorized individuals.

What This Means for Patients

For the 4,824 affected individuals, this breach represents a serious privacy concern. When medical information is compromised, patients face several potential risks:

Identity Theft: Personal information from medical records can be used to open fraudulent accounts, file false tax returns, or commit other forms of identity fraud.

Medical Identity Theft: Criminals may use stolen health information to obtain medical services, prescription drugs, or file fraudulent insurance claims in the victim's name.

Financial Impact: Unauthorized use of insurance information could result in benefits exhaustion, leaving patients unable to access needed care.

Privacy Concerns: Sensitive medical information could be exposed publicly or used for blackmail or discrimination.

The involvement of Strauss Borrelli PLLC in investigating the breach suggests that affected patients may have legal recourse if the healthcare provider failed to implement adequate security measures or respond appropriately to the incident.

How to Protect Yourself

If you are a patient of PET Imaging of Northern Colorado or believe you may be affected by this breach, consider taking the following protective measures:

Monitor Your Accounts: Regularly check your bank statements, credit card bills, and insurance statements for unauthorized activity.

Review Credit Reports: Obtain free credit reports from all three major credit bureaus and look for unfamiliar accounts or inquiries.

Set Up Fraud Alerts: Contact credit reporting agencies to place fraud alerts on your credit files, making it harder for criminals to open new accounts in your name.

Watch for Suspicious Communications: Be wary of unexpected calls, emails, or letters requesting personal or medical information.

Contact Your Insurance Provider: Notify your health insurance company about the breach and monitor your Explanation of Benefits statements for unauthorized claims.

Document Everything: Keep records of any suspicious activity or communications related to the breach.

Prevention Lessons for Healthcare Providers

The PET Imaging of Northern Colorado breach serves as a reminder of the critical importance of email security in healthcare settings. Healthcare providers should implement comprehensive cybersecurity measures including:

Email Security Solutions: Deploy advanced email filtering, anti-phishing tools, and encryption for sensitive communications.

Employee Training: Conduct regular cybersecurity awareness training to help staff identify and respond to potential threats.

Access Controls: Implement role-based access controls to limit who can access sensitive patient information.

Regular Security Assessments: Conduct periodic vulnerability assessments and penetration testing to identify weaknesses.

Incident Response Planning: Develop and regularly test incident response procedures to ensure quick and effective breach response.

Multi-Factor Authentication: Require additional verification steps for accessing email and other systems containing PHI.

As cyber threats continue to evolve, healthcare organizations must remain vigilant and proactive in protecting patient information. The financial and reputational costs of a data breach far exceed the investment required for proper cybersecurity measures.

This incident underscores the ongoing need for healthcare providers to prioritize HIPAA compliance and cybersecurity. Every organization handling protected health information must take comprehensive steps to safeguard patient data and maintain the trust that is fundamental to the healthcare relationship.
