RDP Cracking

To prevent password cracking from brute force attacks, one should always use long and complex passwords. This makes it hard for attackers to guess the password, and brute force attacks will take too much time. Account lockout is another way to prevent the attacker from performing brute force attacks on web applications. However, for offline software, things are not as easy to secure.

A reverse brute force attack is another term that is associated with password cracking. It takes a reverse approach in password cracking. In this, the attacker tries one password against multiple usernames. Imagine if you know a password but do not have any idea of the usernames. In this case, you can try the same password and guess the different usernames until you find the working combination.

Now, you know that a brute-forcing attack is mainly used for password cracking. You can use it in any software, any website or any protocol which does not block requests after a few invalid trials. In this post, I am going to add a few brute force password-cracking tools for different protocols.

I am sure you already know about the Aircrack-ng tool. This is a popular brute force wifi password cracking tool available for free. I also mentioned this tool in our older post on most popular password-cracking tools. This tool comes with WEP/WPA/WPA2-PSK cracker and analysis tools to perform attacks on Wi-Fi 802.11. Aircrack-ng can be used for any NIC which supports raw monitoring mode.

It is available for Windows and Linux platforms. It has also been ported to run on iOS and Android platforms. You can try it on given platforms to see how this tool can be used for brute force wifi password cracking.

John the Ripper is another awesome tool that does not need any introduction. It has been a favorite choice for performing brute force attacks for a long time. This free password-cracking software was initially developed for Unix systems. Later, developers released it for various other platforms. Now, it supports fifteen different platforms including Unix, Windows, DOS, BeOS and OpenVMS.

This tool is very popular and combines various password-cracking features. It can automatically detect the type of hashing used in a password. Therefore, you can also run it against encrypted password storage.

Rainbow Crack is also a popular brute-forcing tool used for password cracking. It generates rainbow tables for using while performing the attack. In this way, it is different from other conventional brute-forcing tools. Rainbow tables are pre-computed. It helps in reducing the time in performing the attack.

Hashcat claims to be the fastest CPU-based password cracking tool. It is free and comes for Linux, Windows and Mac OS platforms. Hashcat supports various hashing algorithms including LM Hashes, MD4, MD5, SHA-family, Unix Crypt formats, MySQL and Cisco PIX. It supports various attacks including brute force attacks, combinator attacks, dictionary attacks, fingerprint attacks, hybrid attacks, mask attacks, permutation attack, rule-based attacks, table-lookup attacks and toggle-case attacks.

Ncrack is also a popular password-cracking tool for cracking network authentications. It supports various protocols including RDP, SSH, HTTP(S), SMB, POP3(S), VNC, FTP and Telnet. It can perform different attacks including brute-forcing attacks. It supports various platforms including Linux, BSD, Windows and Mac OS X.

These are a few popular brute-forcing tools for password cracking. There are various other tools are also available which perform brute force on different kinds of authentication. If I just give an example of a few small tools, you will see most of the PDF-cracking and ZIP-cracking tools use the same brute force methods to perform attacks and crack passwords. There are many such tools available for free or paid.

Brute-forcing is the best password-cracking method. The success of the attack depends on various factors. However, factors that affect most are password length and combination of characters, letters and special characters. This is why when we talk about strong passwords, we usually suggest that users have long passwords with a combination of lower-case letters, capital letters, numbers and special characters. It does not make brute-forcing impossible but it does make it difficult. Therefore, it will take a longer time to reach to the password by brute-forcing.

Ncrack is a high-speed network authentication cracking tool.It was built to help companies secure their networks byproactively testing all their hosts and networking devicesfor poor passwords. Security professionals also rely onNcrack when auditing their clients. Ncrack was designedusing a modular approach, a command-line syntax similar toNmap and a dynamic engine that can adapt its behaviourbased on network feedback. It allows for rapid, yetreliable large-scale auditing of multiple hosts.

Hydra is one of the most famous tools for login cracking used either on Linux or Windows/Cygwin. In addition, for Solaris, FreeBSD/OpenBSD, QNX (Blackberry 10), and macOS. It supports many protocols such as AFP, HTTP-FORM-GET, HTTP-GET, HTTP-FORM-POST, HTTP-HEAD, HTTP-PROXY, and more.

Obtaining and exploiting existing account credentials can support Initial Access Brokers in the stages of initial access, persistence, and privilege escalation. Valid credentials can be obtained in various ways, but, as aforementioned, brute-forcing techniques (T1110) remain the most common. It is relatively easy to find default and common RDP passwords on the internet, like in this GitHub repository. Additionally, various widely-available cracking software such as NLBrute and RDP Forcer can be used by any kind of attacker, regardless of their technical capability.

Offline password cracking, such as using an automated tool to try to crack a Windows Security Account Manager database or the contents of a Linux password shadow file (i.e., /etc/shadow), requires different tools, such as hashcat or John the Ripper.

You can't install RSAT on computers that are running Home or Standard editions of Windows. You can install RSAT only on Professional or Enterprise editions of the Windows client operating system. Unless the download page specifically states that RSAT applies to a beta, preview, or other prerelease version of Windows, you must be running a full (RTM) release of the Windows operating system to install and use RSAT. Some users have found ways of manually cracking or hacking the RSAT MSU to install RSAT on unsupported releases or editions of Windows. This behavior is a violation of the Windows end-user license agreement.

Cain and Abel (often abbreviated to Cain) was a password recovery tool for Microsoft Windows. It could recover many kinds of passwords using methods such as network packet sniffing, cracking various password hashes by using methods such as dictionary attacks, brute force and cryptanalysis attacks.[1]Cryptanalysis attacks were done via rainbow tables which could be generated with the winrtgen.exe program provided with Cain and Abel.[2]Cain and Abel was maintained by Massimiliano Montoro[3] and Sean Babcock.[4]

MFA protects user accounts and can prevent hackers from obtaining access to the network and from escalating privileges once in the network. MFA for remote access to the network and all externally exposed enterprise and third-party applications is required by 23 NYCRR 500.12. All logins to privileged accounts, whether remote or internal, should require MFA, as this is a highly effective way of blocking privilege escalation via password cracking. 23 NYCRR 500.03(d) & (g); 500.12.

Password cracking tools can also be used by system administrators to check for easily hackable passwords. Although traditionally perceived to be used exclusively for criminal purposes, using password hacking tools to test or recover lost passwords is a legal practice. The best password cracker apps can handle multiple targets simultaneously, are usable on different platforms, and support multiple protocols.

John the Ripper is a good choice for a password cracking tool, mainly because of its open-source nature and support for different platforms. The open-source nature means that the code is available to the public, so users do not have to worry about the legality of the software and about potential malware of malicious programs that might be deeply integrated into the software.

Medusa is an online password-cracking tool that supports plenty of protocols, including HTTP, SSH, FTP, CVS, AFP, POP3, Telnet, and more. The software works as a login brute-forcer; many credentials using as many protocols as possible are inputted to arrive at the correct password.

THC Hydra has seen many comparisons to Medusa as a password cracker, but there are notable differences between the two software. Like Medusa, THC Hydra is also an online password cracking tool that uses a brute-force password guessing method. One key difference is that THC Hydra can be installed on Windows, macOS, Linux, Free BSD, and Solaris, notably more platforms than Medusa supports. In addition to the brute-force method, THC Hydra can also use dictionary attacks, using external wordlists.

WFuzz is another brute-force password-cracking tool, much like Medusa and THC Hydra. Another feature of the program is finding hidden resources like servlets, directories, and scripts. The tool also supports multiple injection types with multiple dictionaries.

While most password cracking tools are used to detect easily-cracked passwords, WFuzz can also find injection vulnerabilities in an application, such as XSS injection, SQL injection, and LDAP injection. WFuzz stands out as more than just a password cracker; the software also allows users to detect vulnerabilities and secure Web applications as a whole.

RainbowCrack is another password cracker tool that uses a rainbow table attack to decipher passwords in hash form. The main technique used is the time-memory trade-off technique which can be accelerated with multiple GPUs. Users can use RainbowCrack to generate rainbow tables to be used in the password cracking process or download preexisting rainbow tables from the Internet. 041b061a72
