I saw an article claiming they had infected a third of a million computers by 1-2 days ago. Google claims that private ransomware programs claim a 3% conversion rate, and because this one was spread by worm it is likely to have a greater rate of PCs in business settings (as they are networked) compared to normal. So at least 5 million dollars (avg payment of $450?) and probably pushing up to 8 million by now. Perhaps a ransomware/malware criminal reading this can make a throwaway and provide a better estimate.
