I don't think there is any direct impact on the price but it could certainly make people more fearful of computers and the internet. Thus they might trust technology less and use computers less. Since Bitcoin is based on computers and the internet this could have a negative effect on the price. People may also lose a lot of their money due to the Ransomware and have less funds to spend on Bitcoin. This could also negatively impact the price to a certain degree.

The Ransomware could have indirect positive effects on the price as well. Due to the attacks people may become more knowledgeable about computers and security. This draws them to computers and makes them more likely to but Bitcoin in the future.
