These problems are a part of my Master Thesis Project based on "Security CTF Problems For Beginning Developers Of Low-Resource Real-Time Embedded Systems Software" This reposity contains 5 "coherent" CTF challenges which revolve around a storyline. TODO::Include link to thesis?

• Storyline: Please refer to Section 3 of thesis.

For each problem:

• Problem Statement: Refer to Section 4.< Problem Number >.2

• Hints: Please refer to Section 4.< Problem Number >.3

  To begin:

  • cd EmbeddedSecurityCTFs/FreeRTOS/FreeRTOS/Demo/Posix_GCC/
  • make && build/posix_demo <Problem Number>
  • For example, make && build/posix_demo 1 will launch Problem 1 and so on.

ENJOY!
