We consider the problem of recovering the compiling chain used to generate a given bare binary code. We present a first attempt to devise a Graph Neural Network framework to solve this problem, in order to take into account the shallow semantics provided by the binary code's structured control flow graph (CFG). We introduce a Graph Neural Network, called Site Neural Network (SNN), dedicated to this problem. Feature extraction is simplified by forgetting almost everything in a CFG except transfer control instructions. While at an early stage, our experiments show that our method already recovers the compiler and the optimization level provenance with very high accuracy. We believe these are promising results that may offer new, more robust leads for compiling tool chain identification.
