In 2023, the City of Oakland suffered a severe **ransomware attack** executed by the **Play ransomware group**, exposing the personal data of thousands of current and former **police officers and city employees**. Compromised information included **home addresses, medical records, and Social Security numbers**, which were leaked on the **dark web**. The attack crippled the city’s IT systems for **weeks**, disrupting essential government services and delaying critical operations, including **police misconduct investigations**. The breach led to a **class-action lawsuit** with over **10,000 plaintiffs**, resulting in settlements of **$175 per affected officer** and up to **$350 for other employees** who proved financial harm. The city also offered **three years of free credit monitoring**. An earlier **2022 audit** had warned of **cybersecurity vulnerabilities** due to **understaffing and resource shortages**, but no action was taken. The incident exposed systemic neglect in Oakland’s digital defenses, raising concerns about **identity theft risks**—especially for police in a **high-crime city**—and prolonged **operational disruptions** across municipal services.
