HimitsuShell
Shell scripts to obfuscated binaries
Traditional shell script compilers (e.g., shc) simply wrap shell scripts in C. As a result, scripts can be easily extracted using kernel-level tools such as bpftrace. HimitsuShell embeds a full shell interpreter and applies advanced obfuscation techniques. Even with kernel-level monitoring, nothing is exposed, and reverse engineering is highly difficult.
Hi Product Hunt! I'm MushStory, the developer behind HimitsuShell.
HimitsuShell started as a patented technology in Korea. The goal was simple: protect the proprietary business logic companies embed in their shell scripts.
Existing tools like shc just weren't enough. Kernel-level monitoring still gets through. So I took a different approach and embedded a full shell interpreter directly into the binary, so nothing ever gets logged at the kernel level.
Unless you're a highly skilled reverse engineer, extracting the script should be effectively impossible.
That said, do you see any attack surfaces I might have missed? This is an early launch, and I'd love to hear honest feedback on both the security side and the overall usability.
