FTP

Brute Force

Brute force attacks against FTP servers involve attempting to log in to an FTP server by systematically trying different usernames and passwords. This is typically done using automated tools that can quickly try thousands of combinations until the correct one is found.

Countermeasures

To protect against brute force attacks on FTP servers, consider implementing the following measures:

Strong Passwords: Encourage users to use strong, complex passwords that are difficult to guess.
Account Lockout: Implement account lockout policies that lock an account after a certain number of failed login attempts.
IP Whitelisting: Restrict FTP server access to specific IP addresses to prevent unauthorized login attempts.
Monitoring: Regularly monitor FTP server logs for suspicious login activities.
Two-Factor Authentication: Implement two-factor authentication to add an extra layer of security to FTP logins.

By implementing these countermeasures, you can significantly reduce the risk of successful brute force attacks against your FTP server.

IMAP

Brute Force

Brute force attacks against IMAP are typically carried out using the hydra tool. The following command can be used to launch a brute force attack against an IMAP server:

hydra -l <username> -P <wordlist> -f <target_ip> imap

-l: Specify the username to attack.
-P: Specify the wordlist containing passwords to try.
-f: Stop the attack once the correct password is found.
imap: Specify the protocol to attack.

It is important to note that brute force attacks can be detected by intrusion detection systems (IDS) and can lead to account lockouts.

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

SQL Server

Brute Force

Brute force attacks against SQL Server typically involve attempting to guess usernames and passwords to gain unauthorized access. This can be done using automated tools that systematically try different combinations until the correct one is found. It is important to have strong passwords and implement other security measures to protect against brute force attacks.

Prevention

To prevent brute force attacks against SQL Server, consider implementing the following measures:

Enforce strong password policies
Implement account lockout policies
Monitor and log failed login attempts
Use multi-factor authentication
Limit access to SQL Server to authorized users only

By implementing these measures, you can significantly reduce the risk of unauthorized access through brute force attacks.

Hashcat

Ataques de Hashcat

Ataque de lista de palabras (-a 0) con reglas

Hashcat ya viene con una carpeta que contiene reglas pero puedes encontrar otras reglas interesantes aquí.

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

Ataque de combinación de listas de palabras

Es posible combinar 2 listas de palabras en 1 con hashcat.
Si la lista 1 contenía la palabra "hello" y la segunda contenía 2 líneas con las palabras "world" y "earth". Se generarán las palabras helloworld y 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 $!

Ataque de máscara (-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

Ataque de Wordlist + Máscara (-a 6) / Ataque de Máscara + 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 Forcing

Dictionary Attack

A dictionary attack involves using a list of common passwords to attempt to crack passwords. This method is more efficient than a brute-force attack as it tries a predefined list of passwords.

Brute Force Attack

A brute force attack involves trying all possible combinations of characters until the correct password is found. This method is time-consuming but effective, especially for complex passwords.

Rainbow Tables

Rainbow tables are precomputed tables used in password cracking to reverse hash functions and discover passwords. They can significantly speed up the cracking process by avoiding the need to hash each possible password repeatedly.

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 often used to crack password hashes.

Tools

There are several tools available for performing brute-force attacks on Windows hashes, such as:

John the Ripper: A popular password-cracking tool that can be used for Windows hashes.
Hashcat: Another powerful tool for cracking password hashes, including Windows hashes.
Hydra: A versatile password-cracking tool that supports various protocols, including SMB (used in Windows environments).

Methodology

Capture Hash: Obtain the password hash from the target system.
Select Tool: Choose a suitable brute-force tool based on the hash type.
Configure Tool: Set up the tool with the necessary parameters, such as hash type and character set.
Initiate Attack: Start the brute-force attack and wait for the tool to find the correct password.
Crack Password: Once the tool successfully cracks the password, use it to access the target system.

Considerations

Brute-force attacks can be time-consuming, especially for complex passwords.
It is essential to use a good wordlist and customize the attack parameters for better results.
Always ensure you have permission to perform such attacks, as unauthorized access is illegal.

3000 | LM                                               | Operating-Systems

Brute Force

Introduction

Brute force attacks are a common method used to crack passwords by systematically trying all possible combinations until the correct one is found. This technique can also be applied to crack common application hashes.

Methodology

Identify Hash Algorithm: Determine the hash algorithm used by the application to hash passwords.
Generate Wordlist: Create a wordlist containing common passwords, dictionary words, and variations.
Hash Wordlist: Hash all the words in the wordlist using the same algorithm as the application.
Compare Hashes: Compare the generated hashes with the target hash to find a match.
Automate: Use automated tools like hashcat or John the Ripper to automate the brute force process.

Resources

Hashcat: A popular password cracking tool that supports multiple hash algorithms.
John the Ripper: Another powerful password cracking tool that can be used for brute force attacks.

By following these steps and utilizing the right tools, you can effectively crack common application hashes using brute force techniques.
