Basically, NiCOFF is a COFF and BOF file loader written in Nim. NiCOFF reads a BOF or COFF file, parses and executes it in the memory. Whole project is based on Yasser's and Kevin's COFF Loader projects. Both the loader and beacon functions in these projects were rewritten in Nim.
You can directly compile the source code with the following command:
nim c -d:release Main.nim -o NiCOFF.exe
In case you get the error "cannot open file", you should also install required dependencies:
nimble install ptr_math winim
NiCOFF can take up to three arguments which are BOF or COFF file path, started function entry (you may want to change function pointer), and optional BOF arguments (you can check Kevin's script).
PS C:\Users\test\Desktop\NiCOFF\bin> .\NiCOFF.exe .\ipconfig.x64.o go
