A dynamic binary instrumentation framework like Intel PIN might come in
handy (i. e. do not try to solve this challenge with a static analysis
approach - it might melt your computer and/or your brain).

The Intel PIN manual is a good starting point
(https://software.intel.com/sites/landingpage/pintool/docs/98869/Pin/doc/html/index.html).

Besides, there are a lot of ready-to-use PIN tools(/opt/pin/source/tools/SimpleExamples);
you might want to take a look at the pinatrace tool (SimpleExamples, **not** ManualExamples)
that is already shipped with Intel PIN.

If you're solving the challenge on your local
machine, turning off ASLR might be a good idea (e. g. disabling ASLR per process via 'setarch -R').
