The Washington Attorney General's Office disclosed a data breach affecting Zillow Group on May 19, 2017, stemming from a clerical error that occurred on May 9, 2017. The incident exposed the personal information of 1,086 Washington residents, including highly sensitive data such as names, Social Security numbers, wage details, and tax information. The breach was not the result of a targeted cyber attack or external hack but rather an internal administrative mistake, leading to unauthorized exposure of confidential records. While the scope was limited to a specific group of individuals, the compromised data—particularly Social Security numbers and financial details—posed significant risks, including potential identity theft, financial fraud, or misuse of personal information. Zillow Group likely faced regulatory scrutiny and was required to notify affected individuals, offering credit monitoring or identity protection services as mitigation. The incident highlighted vulnerabilities in data handling procedures, emphasizing the need for stricter internal controls to prevent similar errors in the future.
