Uvalde CISD suffered a **ransomware attack** that disrupted critical operational systems, including **phones, internet, districtwide security systems, and HVAC (air conditioning)**. The attack forced the relocation of students to cooler areas due to malfunctioning HVAC, while internet outages reverted learning to non-digital methods. While no explicit data breach was confirmed, the incident caused **significant operational paralysis**, delaying system restoration and exposing the district to potential **secondary extortion risks** (e.g., threats to sell stolen data on the dark web). Experts highlighted the attack as part of a broader 23% year-over-year surge in ransomware targeting K-12 schools, exploiting their weaker cybersecurity defenses. The district’s recovery efforts remain unclear, including whether a ransom was paid or insurance was leveraged. The attack underscored vulnerabilities in public education sectors, with potential long-term financial burdens on taxpayers and lingering risks of data exposure despite system restoration.
