However, existing solutions suffer from well-known shortcomings in terms of soundness, performance and usability. We present SaBRe, a novel load-time framework for selective binary rewriting. SaBRe rewrites specific constructs of interest — mainly system calls and function prologues — when the program is loaded into memory. This enables users to intercept those constructs at runtime via a modular architecture allowing custom plugins to be linked with SaBRe using a simple and flexible API. We also discuss the theoretical underpinnings of disassembling and rewriting, including conditions for coverage, accuracy, and correctness; and how they affect SaBRe. We developed two backends for SaBRe — one for x86_64 and one for RISC-V — which were in turn used to implement two open-source plugins: a fast sys...
