Data Breach Summary
The American Association of Critical-Care Nurses (AACN) has disclosed a security incident involving its online payment system that may have exposed sensitive financial and personal information of members and customers.
According to official notices, the issue was first discovered in late July 2025, when AACN’s investigation confirmed unauthorized access to payment card data connected to transactions on its website. Approximately 186 Maine residents have been identified as potentially impacted.
AACN explained that it detected unusual activity within its website’s payment system earlier this year and immediately launched an investigation with the assistance of its payment processor and outside cybersecurity experts.
March 8, 2025 – Unauthorized access to payment card data is believed to have begun.
July 31, 2025 – Investigation confirmed evidence of an unauthorized party accessing payment card information.
August 29, 2025 – Maine residents were formally notified of the breach.

The potentially compromised information includes:
Payment card details (card number, expiration date, CVV)
Full name
Contact details (billing and shipping addresses, phone number, email address)
Although AACN could not determine with certainty which specific cards were accessed, the organization chose to notify affected individuals out of an abundance of caution.
