Loretto Hospital recently announced that they were targeted in a cyberattack that may have resulted in a data breach. Sensitive personal identifiable information and personal health information (PHI) in its possession may have been accessed and leaked. According to the security breach notice on their site, Loretto says they are aware of suspicious activity involving its computer network.

After an inital investigation, Loretto Hospital confirmed that sensitive personal data in its systems may have been compromised by an intrusion by unauthorized third party between January 17, 2025, and February 1, 2025.

We are unaware of what data may be leaked, but typically when a hospital reports a data breach, it can include some of the following types of information:

  • Name
  • Social Security number
  • Driver’s license number or state identification card number
  • Account number or credit or debit card number
  • Medical information
  • Health insurance information
  • Unique biometric data
  • Username or email address

Loretto Hospital has posted a notice of the incident on its website, and those who believe they may be at risk should contact an attorney to learn more about taking legal action and seeking compensation. The hospital plans to send breach notification letters to all impacted individuals once its review of the compromised data is complete, but you should not wait to mitigate certain risks if your data may be compromised.
