Earlier this month, Microsoft said "no Windows 10 customers were known to be compromised by the recent WannaCry (WannaCrypt) global cyberattack," adding that "no known ransomware works against Windows 10 S." News outlet ZDNet asked a security researcher to see how good Microsoft's claims were. Turns out, not much. From the report: We asked Matthew Hickey, a security researcher and co-founder of cybersecurity firm Hacker House, a simple enough question: Will ransomware install on this operating system? It took him a little over three hours to bust the operating system's various layers of security, but he got there. "I'm honestly surprised it was this easy," he said in a call after his attack. "When I looked at the branding and the marketing for the new operating system, I thought they had further enhanced it. I would've wanted more restrictions on trying to run privileged processes instead of it being such a short process."
