Additional Material for the Self Modifying Code (SMC) paper.

Authors

Msc. Marcus Botacin, under supervision of Prof. Dr. Marco Zanata and Prof. Dr. André Grégio -- Department of Informatics - Federal University of Paraná.

Goal

Provide a security look over architectural implications of SMC execution.

Repository Organization

• LinuxSimulation/: A simple Linux kernel module to evaluate the cost of performing I/O.
• Cache.Simulator: A PIN-based, flush-aware cache simulator.
• Detector: A PEBS-based SMC detector.
• Examples: SMC code used for evaluation.

Paper

• The article The Self Modifying Code (SMC)-Aware Processor (SAP): A security look on architectural impact and support was published in the Journal of Computer Virology and Hacker Techniques. Check Preprint Here

Challenge

• I included in the Challenge directory a SMC-based CTF challenge presented to me by Katharina Bogad (thanks). I think that playing with it is an interesting exercise to understand SMC better, so I decided to include it in this repository.
