Hikari_pe_x64 Review

Download prebuilt hikari_pe_x64.dll from: github.com/HikariObfuscator/Hikari/releases (look for Hikari-LLVM15.0-windows-x64.zip ) Extract the zip to C:\Hikari\ :

clang-cl.exe /O2 /GS- /c payload.c -mllvm -enable-pass-plugin=C:\Hikari\lib\hikari_pe_x64.dll -mllvm -sub -mllvm -bcf -mllvm -fla -mllvm -split Use lld-link.exe (or MSVC link.exe):

loc_obf_1: mov eax, switch_var cmp eax, 0x1 -> jmp loc_realblock1 cmp eax, 0x2 -> jmp loc_realblock2 ... If prebuilt plugin fails: hikari_pe_x64

lld-link.exe /SUBSYSTEM:CONSOLE /ENTRY:main /MACHINE:X64 /OUT:obfuscated.exe payload.obj Do apply obfuscation at link stage – only per TU (translation unit). 6. Advanced: Selective Obfuscation with __attribute__ Annotate functions to control passes:

__attribute__((annotate("sub"))) __attribute__((annotate("fla"))) void critical_function() // heavily obfuscated Download prebuilt hikari_pe_x64

C:\Hikari\ bin\ clang-cl.exe lld-link.exe lib\ hikari_pe_x64.dll <-- plugin Add to environment PATH : C:\Hikari\bin Use the plugin flag :

Example full obfuscation:

git clone https://github.com/HikariObfuscator/Hikari.git cd Hikari mkdir build && cd build cmake -G "Visual Studio 17 2022" -A x64 -DLLVM_ENABLE_PROJECTS="clang;lld" -DCMAKE_BUILD_TYPE=Release ../LLVM cmake --build . --config Release --target hikari_pe_x64 Plugin will be at Release/lib/hikari_pe_x64.dll . | Error | Fix | |-------|-----| | Failed to load plugin | Use full absolute path to .dll | | Unrecognized flag -sub | Plugin didn’t load – check -enable-pass-plugin | | LNK2001 unresolved external | Add /DEFAULTLIB:libcmt (static CRT) | | Access violation after obf | Disable -split + -fla together | Use hikari_pe_x64 responsibly – only on your own binaries or with explicit permission.
