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/

Requirements

• Node.js v7.6.0 or higher

Usage

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
