Problem
There is something on my shop network running at mercury.picoctf.net:16524, but I can't tell what it is. Can you?
Solution
1.We can use nc to connect to the challenge and output the commands to a file: nc mercury.picoctf.net 16524 > cnc_command.txt
2.Searching for What language does a CNC machine use? finds that the answer is g-code Searching for simulate g-code finds NCViewer (WebGCode is another option).
3.We can paste in the contents of cnc_command.txt into the "GCode File" panel and then click "Plot" to view the flag.
