Description

On July 24, 2025, Ridgefield Public Schools' cybersecurity systems detected an attack aimed at encrypting files on the district's computer network. Upon detection, the network was immediately taken offline to prevent further harm and to allow an investigation to begin. District officials subsequently confirmed that the incident was a ransomware event, involving malicious software used to lock digital files in exchange for demands for a decryption key. Law enforcement agencies were notified and are assisting with the investigation, as stated in a post on the Ridgefield Public Schools website.

The disruption had immediate operational impacts, particularly affecting student registration for the upcoming 2025-26 school year. Those experiencing issues with student registration were directed to contact District Registrar Brigid Clancy by email at [email protected] or by calling 203-894-5550 ext. 1106. However, sports registration was expected to be unaffected, as the district anticipated network restoration prior to registration periods.

In response to the attack, officials took decisive action by taking the entire network offline, effectively containing the threat and preventing further spread of the malicious software. Law enforcement agencies were engaged to assist with the investigation. The district emphasized that the response would be methodical, with services restored in a staggered manner as systems are cleared for use. Officials committed to providing regular updates on the Ridgefield Public Schools website as the investigation progressed and systems were brought back online safely. The district indicated that if forensic analysis reveals that employee financial information was compromised, credit protection services would be offered, and notifications to affected residents would follow Connecticut state law.
