PowerHuntShares：一款针对活动目录域安全的分析与审计工具
关于PowerHuntShares
PowerHuntShares是一款针对活动目录域安全的分析与审计工具，该工具本质上是一个PowerShell脚本，可以帮助广大研究人员清点、分析和报告加入到活动目录域中计算机上SMB共享上配置的过度权限。在该工具的帮助下，IAM和其他红队研究人员可以更好地了解SMB共享相关的攻击面，并提供相关的安全数据见解，以帮助企业和各大组织以更加安全的方式管理大规模分组共享。
功能介绍
当前版本的PowerHuntShares支持下列功能：
1、使用当前用户上下文、凭据或明文用户/密码进行身份验证；
2、自动发现与活动目录域关联的可访问系统。它还将根据可用的开放端口筛选活动目录中的计算机；
3、以单个计算机、计算机列表或发现的活动目录计算机为目标（默认）；
4、使用PowerShell从目标计算机收集SMB共享的ACL信息；
5、支持分析收集到的共享ACL数据；
6、以HTML和CSV文件格式生成过度权限检测详细报告；
SMB共享的ACL分配过多，这是一个系统性问题，也是所有企业和组织都难以应对的攻击面。因此，该项目的目标就是为了解决这个问题，并构建了一个更好的共享收集和数据洞察引擎，以帮助广大研究人员更好地了解活动目录域的安全态势。
工具下载
广大研究人员可以使用下列命令将该项目源码克隆至本地：
git clone https://github.com/NetSPI/PowerHuntShares.git
工具配置
下面给出的命令可以帮助我们将将PowerHuntShare加载到当前PowerShell会话中，请注意，每次运行PowerShell时都必须运行其中一个命令，且不是持久化的：
# 绕过执行策略限制
Set-ExecutionPolicy -Scope Process Bypass
# 导入存在于当前目录中的模块
Import-Module .\PowerHuntShares.psm1
# 降低SSL操作登记以支持与github连接
[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
[Net.ServicePointManager]::SecurityProtocol =[Net.SecurityProtocolType]::Tls12
# 下载并将PowerHuntShares.psm1导入到内存中
IEX(New-Object System.Net.WebClient).DownloadString("https://raw.githubusercontent.com/NetSPI/PowerHuntShares/main/PowerHuntShares.psm1")工具使用样例
注意事项：该工具所有的操作命令需要以非特权域用户运行。
.EXAMPLE 1: 从一个域计算机运行，默认执行活动目录计算机扫描。 PS C:\temp\test> Invoke-HuntSMBShares -Threads 100 -OutputDirectory c:\temp\test .EXAMPLE 2: 使用其他域凭据从域计算机运行，默认情况下执行活动目录计算机扫描。 PS C:\temp\test> Invoke-HuntSMBShares -Threads 100 -OutputDirectory c:\temp\test -Credentials domain\user .EXAMPLE 3: 以当前用户身份从域计算机运行，文件中的目标主机每行设置一个。 PS C:\temp\test> Invoke-HuntSMBShares -Threads 100 -OutputDirectory c:\temp\test -HostList c:\temp\hosts.txt .EXAMPLE 4: 使用凭据从非域计算机运行，默认情况下执行活动目录计算机扫描。 C:\temp\test> runas /netonly /user:domain\user PowerShell.exe PS C:\temp\test> Import-Module PowerHuntShares.psm1 PS C:\temp\test> Invoke-HuntSMBShares -Threads 100 -RunSpaceTimeOut 10 -OutputDirectory c:\folder\ -DomainController 10.1.1.1 -Credential domain\user =============================================================== PowerHuntShares =============================================================== This function automates the following tasks: o Determine current computer's domain o Enumerate domain computers o Filter for computers that respond to ping reqeusts o Filter for computers that have TCP 445 open and accessible o Enumerate SMB shares o Enumerate SMB share permissions o Identify shares with potentially excessive privielges o Identify shares that provide reads & write access o Identify shares thare are high risk o Identify common share owners, names, & directory listings o Generate creation, last written, & last accessed timelines o Generate html summary report and detailed csv files Note: This can take hours to run in large environments. --------------------------------------------------------------- ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| --------------------------------------------------------------- SHARE DISCOVERY --------------------------------------------------------------- [*][03/01/2021 09:35] Scan Start [*][03/01/2021 09:35] Output Directory: c:\temp\smbshares\SmbShareHunt-03012021093504 [*][03/01/2021 09:35] Successful connection to domain controller: dc1.demo.local [*][03/01/2021 09:35] Performing LDAP query for computers associated with the demo.local domain [*][03/01/2021 09:35] - 245 computers found [*][03/01/2021 09:35] Pinging 245 computers [*][03/01/2021 09:35] - 55 computers responded to ping requests.
