POP

Brute Force

Brute force attacks are one of the simplest and most common types of attacks. The attacker tries every possible combination of usernames and passwords until the correct one is found. This method is time-consuming but effective, especially against weak passwords.

Dictionary Attack

A dictionary attack is similar to a brute force attack, but instead of trying every possible combination, it uses a predefined list of common passwords. This method is faster than a brute force attack and can be very effective if the target is using a common or weak password.

Rainbow Table Attack

A rainbow table attack is a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes. This method can be very fast and efficient, especially against hashed passwords.

Credential Stuffing

Credential stuffing is the automated injection of breached username/password pairs to gain unauthorized access to user accounts. Attackers use automated tools to test large numbers of credentials against various websites and services to find valid login information.

Hydra

Hydra is a popular password-cracking tool that can perform rapid dictionary and brute-force attacks. It supports multiple protocols and can be used to crack passwords for various services and platforms.

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

VNC

Brute Force

Brute forcing VNC involves trying all possible username and password combinations until a successful login is found. Tools like Hydra and Medusa can be used for this purpose.

Protection

To protect against brute force attacks on VNC, it is recommended to use strong, complex passwords and implement account lockout policies after a certain number of failed login attempts. Additionally, using VPNs or restricting VNC access to specific IP addresses can add an extra layer of security.

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

Keepass

Brute Force

Brute force attacks are a common way to gain unauthorized access to a Keepass database. Attackers use automated tools to try all possible combinations of passwords until the correct one is found. This method can be time-consuming but is effective if the password is weak.

Protection

To protect against brute force attacks, it is essential to use a strong and unique password for your Keepass database. Additionally, enabling two-factor authentication can add an extra layer of security to prevent unauthorized access. Regularly updating your passwords and keeping your Keepass software up to date can also help mitigate the risk of brute force attacks.

sudo apt-get install -y kpcli #Install keepass tools like keepass2john
keepass2john file.kdbx > hash #The keepass is only using password
keepass2john -k <file-password> file.kdbx > hash # The keepass is also using a file as a needed credential
#The keepass can use a password and/or a file as credentials, if it is using both you need to provide them to keepass2john

Brute Force

Description

Brute force is a common technique used to crack passwords by systematically trying all possible combinations of characters until the correct one is found. This method is often used to crack Linux hashes stored in the /etc/shadow file.

Tools

  • John the Ripper: A popular password cracking tool that can be used for brute force attacks.
  • Hashcat: Another powerful tool for cracking passwords using brute force and other techniques.

Methodology

  1. Obtain the hash from the /etc/shadow file.
  2. Use a password cracking tool like John the Ripper or Hashcat to perform a brute force attack.
  3. Configure the tool to try different combinations of characters, such as letters, numbers, and symbols.
  4. Monitor the progress of the brute force attack and wait for the correct password to be found.
  5. Once the password is cracked, it can be used to gain unauthorized access to the system.

Prevention

  • Use strong, complex passwords that are less susceptible to brute force attacks.
  • Implement multi-factor authentication to add an extra layer of security.
  • Regularly update passwords and monitor for any unauthorized access attempts.
