What Happened?

Recently, Guardant Health realized that it had placed the protected health information of its patients online without any protections whatsoever. This information was uploaded online in October of 2020 and remained accessible for over three years. Between September 8, 2023, and February 28, 2024, an unknown actor discovered and copied the file containing unencrypted medical data. To date, it is unknown whether any other actor downloaded or copied the file during the three and a half years it was available online. Subsequently, on May 3, 2024, Guardant Health filed a notice of the data breach, and data breach letters were sent out to all individuals affected by the incident, providing them with a list of compromised information.
