Lake Washington Vascular Data Breach Class Action

At Console & Associates, our data breach lawyers are closely examining the recent Lake Washington Vascular data breach. This data breach was disclosed following a cyber security incident at Lake Washington Vascular, which may have affected as many as 21,000 individuals, potentially exposing sensitive personal identifiable information and protected health information.

What Happened?

A recent report from the U.S. Department of Health and Human Services Office for Civil Rights states that the Lake Washington Vascular data breach occurred due to a malware attack. On February 14, 2025, the company discovered an unauthorized party had infiltrated their network and was attempting to install malicious software. While Lake Washington Vascular took steps to halt the attack by eliminating unauthorized access, their systems were already encrypted by the malware.

Following the incident, the company conducted an investigation which confirmed that the unauthorized party had accessed files and folders containing confidential patient information. The compromised data includes:

• names,
• dates of birth,
• addresses,
• payer identification numbers,
• government-issued IDs,
• diagnostic test results,
• medical histories,
• and treatment information.

Data breach letters were sent out by Lake Washington Vascular on February 25, 2025, informing affected individuals about the nature of the incident and compromised data. The company also filed a formal notice with federal authorities on the same date.
