PET Imaging of The Woodlands Email Breach Exposes 2,978 Patients

A healthcare data breach at PET Imaging of The Woodlands in Texas has compromised the protected health information (PHI) of 2,978 patients. The incident, reported to the Department of Health and Human Services on June 27, 2025, involved unauthorized access to the medical facility's email system through a hacking/IT incident.

What Happened

PET Imaging of The Woodlands, a medical imaging facility in Texas, experienced a cyberattack that targeted their email infrastructure. The breach was classified as a hacking/IT incident with the location of breach specifically identified as their email system.

A business associate was involved in this incident, which is significant under HIPAA regulations. Under the HIPAA Business Associate Rule (45 CFR § 164.308), healthcare providers must ensure that their business partners who handle PHI maintain appropriate safeguards. When a business associate experiences a breach, they are required to notify the covered entity within 60 days of discovery.

While specific details about the attack methodology remain limited, email-based breaches typically involve:

• Phishing attacks targeting employee credentials
• Malware deployment through malicious attachments
• Account takeover through compromised passwords
• Man-in-the-middle attacks intercepting email communications

Who Is Affected

The breach impacted 2,978 individuals who received medical imaging services at PET Imaging of The Woodlands. Patients who underwent procedures such as:

• PET scans (Positron Emission Tomography)
• CT scans
• Nuclear medicine procedures
• Other diagnostic imaging services

May have had their sensitive health information compromised during this incident.

Breach Details

While comprehensive details remain limited, here's what we know:

• Entity Type: Healthcare Provider specializing in medical imaging
• Breach Classification: Hacking/IT Incident under 45 CFR § 164.402
• Attack Vector: Email system compromise
• Timeline: Reported June 27, 2025
• Business Associate Involvement: Yes, indicating third-party vendor compromise
• Scale: Medium-sized breach affecting nearly 3,000 patients

Under HIPAA's Breach Notification Rule (45 CFR § 164.404), healthcare providers must report breaches affecting 500 or more individuals to HHS within 60 days of discovery. This incident clearly meets that threshold.

What This Means for Patients

Email breaches at healthcare facilities can expose various types of protected health information, including:

• Personal identifiers (names, addresses, phone numbers)
• Medical record numbers
• Insurance information
