LD_PRELOAD AFNOM Talk

This repo contains the slide deck / code examples for my lighning talk about LD_PRELOAD for the University of Birmingham's ethical hacking club AFNOM.

Building the slides

It can be built using Marp like so:

• Development: marp -w -s ./
• Final PDF: marp --pdf=true slides.md

Code Examples

All code referenced is provided in the src directory.

Per the slides, here's how you can explore LD_PRELOAD

1. Run make to compile both binaries
   • $ make
2. Run the random_number binary a few times:
   • $ ./random_number
3. Now, run the random_number binary after preloading the unrandom library:
   • $ env LD_PRELOAD=$PWD/unrandom.so ./random_num

TODO

• More examples of what you can do with this?
