with open('username.txt','r') as files:
    for file in files:
        # 正则表达式匹配 email
        email_pattern = re.compile(r'\b[\w.-]+@xiaorang\.lab\b')

        # 提取所有匹配的 email
        emails = email_pattern.findall(file)

        # 输出所有 email
        for email in emails:
            print(email)

写个脚本可以把用户名提出来，先确认一下哪些是有效的域内用户，然后用脚本提取出来

AS-REPRoasting

在AS_REP阶段，会返回由我们请求的域账户hash加密某个值后返回。然后我们通过自身的ntlm hash去解密得到数据。在这里设置不要求预身份验证后，我们可以在AS_REQ阶段，填写想要伪造请求的用户名，随后会用伪造请求的用户名NTLM Hash加密返回给我们。随后我们就可以拿去爆破了

使用域内有效用户去查SPN

rdp上去，用bloodhound做一下信息收集

如果将A域中的域用户迁移到B域中，那么在B域中该用户的SID会随之改变，进而影响迁移后用户的权限，导致迁移后的用户不能访问本来可以访问的资源。SID History的作用是在域迁移过程中保持域用户的访问权限，即如果迁移后用户的SID改变了，系统会将其原来的SID添加到迁移后用户的SID History属性中，使迁移后的用户保持原有权限、能够访问其原来可以访问的资源。

简单来说yuxuan属于域管，所以现在拿到yuxuan的权限然后dump哈希就好了，上小豆子收集一波信息

╔══════════╣ Looking for AutoLogon credentials
    Some AutoLogon credentials were found
    DefaultDomainName             :  xiaorang.lab
    DefaultUserName               :  yuxuan

可以发现自动登录用户，正好就是yuxuan，用此用户rdp上去，dump域管哈希
