A Broad Comparative Evaluation of x86-64 Binary Rewriters

Abstract

Binary rewriting is a rapidly-maturing technique for modifying software for instrumentation, customization, optimization, and hardening without access to source code. Unfortunately, the practical applications of binary rewriting tools are often unclear to users because their limitations are glossed over in the literature. This, among other challenges, has prohibited the widespread adoption of these tools. To address this shortcoming, we collect ten popular binary rewriters and assess their generality across a broad range of input binary classes and the functional reliability of the resulting rewritten binaries. Additionally, we evaluate the performance of the rewriters themselves as well as the rewritten binaries they produce.
