Today the PGA Championship kicks off, and just as with the Olympics and World Cup, a cyberattack has tried to interfere. Two days ago, the servers of PGA of America were hacked and infected with ransomware.

Oddly, while a bitcoin address was provided, no specific ransomware was cited. The files encrypted included promotional banners and logos.

Golfweek, which broke the story, reports that PGA of America’s staff were met with an ‘ominous’ message when they tried to open their files: “Your network has been penetrated. All files on each host in the network have been encrypted with a strong algorythm [sic].”

The servers were still not completely restored as of Wednesday afternoon, according to Golfweek. However, the PGA Championship is expected to go on as planned, and is not expected to be impacted.
