Description

In September, the Slate Valley Unified School District experienced a cybersecurity breach that allowed hackers to access business documents and employees’ personal information. After discovering the intrusion, district officials said that hackers had accessed business documents and employees’ personal information and that the district later received a ransom demand threatening to release that data. The ransom amount was described by district leaders as substantial. Upon receiving the demand, the school board consulted with legal counsel and decided not to pay the ransom. District leaders stated that they did not want to cancel school as a result of the incident. They explained that staff pulled together and created workarounds for every different scenario to keep operations running. The breach forced the district to adapt without many of its core online systems.

Officials say they continue to work with law enforcement. The district is notifying individuals whose information may have been impacted by the cyberattack. District leaders have stated that they do not believe any student data was leaked as a result of the incident. District leaders explained that staff have been using workarounds to maintain essential functions while core systems remain unavailable.
