Pipe Injector

Node.js script that can detect when "curl ... | bash" is being used and serve a different file than normal. This is an implementation of this article https://www.idontplaydarts.com/2016/04/detecting-curl-pipe-bash-server-side/

The first 4 lines of injector.js are the settings used to configure the program:

initalFile is the file sent regardless of good or bad. It must be set to a file in it that has at least a sleep inside. I've found 2 seconds to work, but other delays may be necessary.
goodFile is the file served if piping is not detected.
badFile is the file served if piping is detected.
Port is what port number to bind the HTTP server on
minStd is the minimum standard deviation of the time needed to send each "filler" packet required to send badFile
