The compromise of passwords is always a serious threat to the confidentiality and integrity of data. Generally, the passwords shorter than 7 characters are especially susceptible to bruteforce attack. However, a sequence of mistyped commands or incorrect login responses (with attempts to recover or reuse them) can be a signs of brute-force intrusion attempts.

Password hacking software has evolved tremendously over the last few years but essentially it comes down to several things: firstly, what systems are in place to prevent certain popular types of password cracking techniques (for example ‘captcha forms’ for brute force attacks), and secondly, what is the computing processing power of the hacker?
Brute force attack is a process of guessing a password through various techniques. Commonly, brute force attacks are divided into three categories:
a) Traditional Brute Force
In a traditional brute force attack, you will try all the possible combinations to guess the correct password. This process is very usually time consuming; if the password is long, it will take years to brute-force. But if the password is short, it can give quick results.
b) Dictionary Attacks
In a dictionary-based brute force attack, we use a custom wordlist, which contains a list of all possible username and password combinations. It is much faster than traditional brute force attacks and is the recommended approach for penetration tests.
c) Hybrid Attacks
Hybrid brute force attacks are a combination of both traditional brute force attack and dictionary based attack. The idea behind a hybrid attack is that it will apply a brute force attack on the dictionary list.
Using bruteforce attacks, an attacker could gain full access to the affected machine. When conducting brute force attacks or password attacks, faster processing speed is beneficial. In cases where remote brute force attacks are conducted, bandwidth constraints must be addressed.
1. THC Hydra
THC hydra is one of the oldest password cracking tools developed by “The Hackers Community“. By far, Hydra has the most protocol coverage than any other password cracking tool as per our knowledge, and it is available for almost all the modern operating systems. THC Hydra can perform rapid dictionary attacks against many protocols such as Telnet, FTP, HTTP, SMB etc.
Here is the basic syntax for hydra (Linux version) to brute-force a service.

2. Aircrack-Ng
Aircrack-ng is another most popular brute force wireless hacking tool which is further used to assess WiFi network security. Generally it focuses on different 4 areas of WiFi security i.e. Monitoring, Attacking, Testing and Cracking.
Aircrack-ng is a set of tools widely used to crack/recover WEP/WPA/ WPA2-PSK. It supports various attacks such as PTW, which can be used to decrypt WEP key with a less number of initialization vectors, and dictionary/brute force attacks, which can be used against WPA/WPA2-PSK. It includes a wide variety of tools such as packet sniffer and packet injector. The most common ones are airodump-ng, aireply-ng, and airmon-ng.

3. Ncrack
Ncrack is one of our favorite tool for password cracking. It is based upon nmap libraries. It comes pre-installed with Kali Linux OS. It can be combined with nmap to yield great results. The only disadvantage is that it supports very few services, namely, FTP, SSH, Telnet, FTP, POP3, SMB, RDP, and VNC.

6. Ophcrack
Ophcrack is a Windows-based tool that has the capability to not only dump the hashes, but also crack those hashes using rainbow tables. Sims 4 white eyes. The ophcrack program comes with rainbow tables that work for passwords of a very short length. Jax for mac. So if the password is lengthy, or, say, alphanumeric, you won’t be able to crack it.

10. L0phtcrack
Wifi Brute Force Attack Software
L0phtCrack is a password auditing and recovery application originally produced by Mudge from L0pht Heavy Industries. It is used to test password strength and sometimes to recover lost Microsoft Windows passwords, by using dictionary, brute-force, hybrid attacks, and rainbow tables. It was one of the crackers’ tools of choice, although most use old versions because of its low price and high availability.
