A targeted cyber attack compromised the **CodeRED emergency notification system** in Harrisburg, SD, operated by **OnSolve (Crisis24)**. The incident was contained within the CodeRED environment, but hackers gained access to a server, potentially exposing **user data**—including **names, addresses, email addresses, and phone numbers**—though no highly sensitive information (e.g., financial or medical records) was breached. The primary motive appeared to be **ransom extraction**, though no payment demands were explicitly confirmed. The affected server was promptly isolated, and services were migrated to a new server, with full restoration expected by late November 23 or early November 24. While the attack disrupted emergency alert capabilities (raising concerns ahead of a snowstorm), no broader systemic damage or lateral movement into other city systems occurred. The breach underscored vulnerabilities in third-party notification platforms, though the exposed data was limited to basic contact details used for public alerts.
