GoStringUngarbler is a Python command-line tool designed to extract and deobfuscate strings from Go binaries that have been obfuscated using the Garble tool. It specifically works when Garble is compiled with the `-literals` flag, which is not always the case, leaving many binaries with strings still in plain text. The project is hosted on GitHub and isn't officially supported by Google, meaning it won't qualify for any vulnerability rewards programs. To use GoStringUngarbler, you need to clone the repository and install Python dependencies like Unicorn and Capstone. The command-line interface requires an input file— the garble-obfuscated executable— and optional parameters for specifying output paths for the deobfuscated binary and a string dump. The tool currently supports Windows (PE) and Linux (ELF) binaries from Garble versions 0.11.0 to 0.13.0 and Go versions 1.21 to 1.23. If newer Go versions are released, additional regex patterns will need to be added to maintain compatibility. The deobfuscation process involves analyzing the binary for specific decrypting subroutines and manipulating them through a patched stub that prepares arguments for a runtime function. This technique allows the tool to effectively retrieve decrypted strings by directly writing them into the binary. The article also hints at future improvements, such as expanding support for different architectures and older Go compiler versions, as well as optimizing the process by eliminating the need for wrapper subroutines in some cases.
