  • 0

I need to set an environment variable in Python and find the address in memory where it is located. Since it’s on Linux, I don’t mind about using libraries that only work consistently on Linux (if that’s the only way). How would you do this?

Edit: The scope of the problem is as follows: I’m trying to hack a program for class, and essentially I’m putting my shellcode into an environment variable and then overwriting one byte on the victim code with the address of my environment variable. I need to find a way to automate this in Python, so my question is two-fold:

  • Is there a way to get the address in memory of an environment variable?

  • Can this only be done in bash/C or can I do it purely in Python?
