what is this

Programs that are dynamically linked load the file in the LD_PRELOAD environment file before running. For example, I could overwrite the rand() function to return whatever I want (and a more detailed explanation is here.

The idea is to insert the backdoor into a function that's always called, so that no matter when someone runs a dynamically linked file, it'll run our backdoor.
