1. What is hikari_pe_x64? hikari_pe_x64 is a LLVM obfuscator plugin (based on Hikari/Obfuscator-LLVM) specifically compiled to work with MSVC/clang-cl on Windows targeting x64 PE executables . It transforms IR code to resist static/dynamic analysis. ⚠️ Not to be confused with “hikari” (anime character). This is a security research tool. 2. Prerequisites | Component | Requirement | |-----------|-------------| | Windows | 10/11 (x64) | | LLVM/Clang | 15.x or 16.x (clang-cl) | | Build tools | Visual Studio 2022 (with “C++ CMake tools”) | | Python | 3.8+ (for scripts) |
