What Happened?

On October 13, 2023, City of Hope, a renowned cancer treatment and research organization, detected suspicious activity within a segment of its systems. They acted swiftly to control any potential disruption to their operations. With the aid of a top-tier cybersecurity firm, City of Hope initiated a thorough investigation to understand the nature and extent of the breach.

The types of information exposed included names, addresses, Social Security numbers, driver's license numbers, government-issued ID numbers, financial information, medical information, health insurance details, and dates of birth.
