PGA of America computers were this week infected with a strain of malicious software that locked down critical files and demanded cryptocurrency for their return.

Officials discovered on Tuesday that servers had been targeted in a ransomware attack which had blocked them from accessing material relating to major golf tournaments, including this week’s PGA Championship at Bellerive Country Club. Some signage had been in development for over a year and could not be reproduced quickly, Golfweek reported.
