I don't know about this situation. That is true. However, I do know about a lot of other situations where ransomware has struck in the past. A lot of those which had problems were due to configuration problems. People got hit with ransomware and you don't know about it because they limited the spread and recovered quickly. The ones who get articles here usually had more trouble, either a more pervasive spread, difficulty recovering from insufficient backups, or both. Therefore, if an organization is having a lot of trouble because of a ransomware situation, I view it as more likely they didn't take a backup step than they were hit with a very sophisticated ransomware variant.
