The details of approximately 540,000 sports referees, league officials and game officials have been stolen by hackers after an attack on ArbiterSports, a company owned by the National Collegiate Athletic Association (NCAA) to provide match scheduling and training software and services.
According to data breach notification letters sent out by ArbiterSports, some months ago it detected that its computer network had been breached, and that the hackers had attempted to encrypt data through a ransomware attack.
