Emergency notification systems across the US disrupted after OnSolve CodeRED cyber attack


  • OnSolve’s legacy CodeRED platform hit by cyber attack claimed by INC Ransom
  • The hack forced Crisis24 to rebuild from outdated backups, permanently losing recent accounts and data
  • The Douglas County Sheriff’s Office and 911 Board cut ties with CodeRED, citing citizen privacy concerns

OnSolve, a cloud-based critical incident and mass notification platform, recently suffered a highly disruptive cyber attack that forced it to shelve its old CodeRED environment and move to a new version, losing sensitive data and even an enterprise customer.

OnSolve is a service that helps organizations send emergency alerts and communications via SMS, phone, email, push notifications and more. It is used by state and local authorities, the police and other emergency services. CodeRED is the platform that enables this service.
