The U.S. federal judiciary’s **Case Management/Electronic Case Files (CM/ECF) and PACER systems** suffered a **sweeping cyber intrusion**, exposing **sensitive, unclassified data**, including **witness identities and ongoing criminal investigation details**. The breach was exploited by **multiple threat actors**, including **Latin American drug cartels and nation-states**, some of whom maintained **persistent access** for extended periods. The stolen data poses severe risks, as cartels could **weaponize the information**—potentially endangering witnesses, compromising investigations, or leveraging it for blackmail and coercion. The incident underscores systemic vulnerabilities in federal cybersecurity, exacerbated by the **democratization of hacking tools**, which lower the barrier for sophisticated attacks. The **reactive 'education-by-breach' approach** of U.S. agencies has proven inadequate against such **diverse, persistent threats**, necessitating a **centralized, proactive response** like shared incident case studies and coordinated security uplifts. The breach not only jeopardizes **national security** but also erodes public trust in judicial and law enforcement institutions.
