A new Rapid7 National Exposure Index found that 160 million computers, servers and IoT devices have open ports not meant to be exposed on public networks.
And when it came to the file-sharing SMB port 445 vulnerability exposed with the WannaCry attacks, 4.6 million internet-connected devices left this port open in 2016. Just after the attacks Rapid7 checked this statistic again and found that even with the SMB port vulnerability known, still 5.5 million internet-connected devices still had exposed ports.
