"This may lead to the impossibility of recovery of certain files.”
Citing an anonymous source, Golfweek.com reported that the files contained creative materials for the PGA Championship at Bellerive and next month’s Ryder Cup in France.
That includes extensive promotional banners and logos used in digital and print communications, and on digital signage around the grounds at Bellerive.
The message also included a Bitcoin wallet number, but no specific ransom amount was demanded.
