Linux On Android Ssh Password Crack
I strongly recommend you to always change default passwords (e.g. "alpine", which is a terrible error not to change) and always choose a very strong password if you are thinking to open you server to the wan. Follow OTW's recent demonstrations about how easy password cracking is, and also his advices on how to protect yourself from these attacks.

The GPU tool can crack some hashcat-legacy in a shorter time than the CPU tool (MD5, SHA1, and others). But not every algorithm can be cracked quicker by GPUs. However, Hashcat had been described as the fastest password cracker in the world.
Hashcat enables highly-parallelized password cracking with the ability to crack multiple different passwords on multiple different devices at the same time and the ability to support a distributed hash-cracking system via overlays. Cracking is optimized with integrated performance tuning and temperature monitoring.
John the Ripper offers password cracking for a variety of different password types. It goes beyond OS passwords to include common web apps (like WordPress), compressed archives, document files (Microsoft Office files, PDFs and so on), and more.
Brutus is one of the most popular remote online password-cracking tools. It claims to be the fastest and most flexible password cracking tool. This tool is free and is only available for Windows systems. It was released back in October 2000.
Brutus has not been updated for several years. However, its support for a wide variety of authentication protocols and ability to add custom modules make it a popular tool for online password cracking attacks.
Wfuzz is a web application password-cracking tool like Brutus that tries to crack passwords via a brute-force guessing attack. It can also be used to find hidden resources like directories, servlets and scripts. Wfuzz can also identify injection vulnerabilities within an application such as SQL injection, XSS injection and LDAP injection.
Medusa is an online password-cracking tool similar to THC Hydra. It claims to be a speedy parallel, modular and login brute-forcing tool. It supports HTTP, FTP, CVS, AFP, IMAP, MS SQL, MYSQL, NCP, NNTP, POP3, PostgreSQL, pcAnywhere, rlogin, SMB, rsh, SMTP, SNMP, SSH, SVN, VNC, VmAuthd and Telnet.
Medusa is a command-line tool, so some level of command-line knowledge is necessary to use it. Password-cracking speed depends on network connectivity. On a local system, it can test 2,000 passwords per minute.
RainbowCrack is a password cracking tool designed to work using rainbow tables. It is possible to generate custom rainbow tables or take advantage of preexisting ones downloaded from the internet. RainbowCrack offers free downloads of rainbow tables for the LANMAN, NTLM, MD5 and SHA1 password systems.
OphCrack is a free rainbow table-based password cracking tool for Windows. It is the most popular Windows password cracking tool but can also be used on Linux and Mac systems. It cracks LM and NTLM hashes. For cracking Windows XP, Vista and Windows 7, free rainbow tables are also available.
L0phtCrack is an alternative to OphCrack. It attempts to crack Windows passwords from hashes. For cracking passwords, it uses Windows workstations, network servers, primary domain controllers and Active Directory. It also uses dictionary and brute-force attacks for generating and guessing passwords. It was acquired by Symantec and discontinued in 2006. Later, L0pht developers again reacquired it and launched L0phtCrack in 2009.
Aircrack-ng is a Wi-Fi password-cracking tool that can crack WEP or WPA/WPA2 PSK passwords. It analyzes wireless encrypted packets and then tries to crack passwords via the dictionary attacks and the PTW, FMS and other cracking algorithms. It is available for Linux and Windows systems. A live CD of Aircrack is also available.
In this post, we have listed 10 password-cracking tools. These tools try to crack passwords with different password-cracking algorithms. Most of the password cracking tools are available for free. So, you should always try to have a strong password that is hard to crack. These are a few tips you can try while creating a password.
Password-cracking tools are designed to take the password hashes leaked during a data breach or stolen using an attack and extract the original passwords from them. They accomplish this by taking advantage of the use of weak passwords or by trying every potential password of a given length.
This article will focus on tools that allow remote service brute-forcing. These are typically Internet facing services that are accessible from anywhere in the world. Another type of password brute-force attack are against the password hash. Powerful tools such as Hashcat can crack encrypted password hashes on a local system.
Note that on non-rooted you cannot use some tools which require root permissions . However, this still remains utilitarian when performing memory intensive operations like Password cracking and bruteforcing. Most mobile devices nowadays come with a lot of RAM and brilliant processors which can help to crack password hashes or bruteforce our way into systems all the while retaining the functionalities of a normal Android Device.
Or perhaps a user offers up just enough variation on the classic password selection to get past the minimal rules of the service. Unfortunately, "Pa$$w0rd!" isn't secure in any meaningful way, either. At this point, almost every variation of words and phrases strung together with a few numbers or substitutions is simply too easy for a password cracking tool to make its way through, and the shorter the password, the easier.
Most security experts agree that one of the biggest security vulnerabilities is the password. Despite a growing concern for privacy and anonymity, users and IT departments alike are ignoring basic cybersecurity best practices, especially password hygiene. In this article we will introduce you to some tools that will demonstrate how easy it is to gain unauthorized access via password cracking and brute force attacks.
Hydra is a password cracking tool used to perform brute force / dictionary attacks on remote systems. It is available on many different platforms such as Linux, Windows and even Android. Hydra is capable of using many popular protocols including, but not limited to, RDP, SSH, FTP, HTTP and many others. Because of its module engine, support for new services can easily be added.
Now that we have a more robust password dictionary we can launch another brute force attack attempt to crack the password. This time we will pass the new mangled password list to Hydra and hope we get a hit.
hashcat is a powerful and versatile tool that brute forces the stored credentials using known hashes by conducting various modes of attacks. The article covers this password cracking utility used by penetration testers, system administrators, spies, or hackers to find passwords.
hashcat offers a variety of attack modes (Combinator, Rule-based, Brute-force guessing, hybrid, and dictionary attacks) to provide better coverage. Here is an explanation of some attacks that hashcat uses to crack hashed passwords:
Hence, if you come across a readable /etc/shadow file through any regular user account, you can get the hash value of the root account and crack the password hash using the hashcat utility.
A well-built authentication system does not store user passwords in plain text and clear sight as they can cause security vulnerabilities. A better authentication mechanism stores passwords as hashes in secure and inaccessible files. However, a password cracker such as hashcat is designed to decipher or guess the passwords using various attack modes.
This article details ways a penetration tester must know to crack hashed passwords using the hashcat utility. As a red teamer, it's necessary to understand the techniques an attacker can use to compromise the authentication controls and provide guidelines on covering system loopholes.
But sometime this password is creating trouble for users itself because In long time user does not use his correct credential for accessing services he will forget soon due to human tendency. I will tell you about a router password cracker tool which help you to recover router password.
The biggest problem is start from the here because it will ask for the username and password if you have the forgotten me your credential then you will not able to access router configuration page. so for getting know the correct username and password you can use Router password cracker tool hydra.
1st factor: The private key. (something you have)2nd factor: The password to encrypted the private key. (something you know)Bingo! 2FA for cheap. It doesn't get any more complicated then that. FreeIPA would be VERY overkill if that is all you want. What FreeIPA can get you is kerberos support for your enterprise, management of sudo rules, ldap, manage selinux rules, it's own RBAC for network services, and all that fun stuff. For securing OpenSSH you can use kerberos or have FreeIPA manage the SSH keys. It can manage your user's public key for them and also manage your host SSH keys (all stored in LDAP). That way it makes the 'unknown host key' feature for ssh work better.For fanciness you can do OTP with FreeIPA. You can use the embedded OTP and radius server that ships with FreeIPA or you can use a external OTP service via a radius server. The most basic FreeIPA OTP usage is to lock down the user's web interface so they will need to use their token + password to do self-management things like changing passwords for kerberos or for uploading their ssh public key.All of this is not terribly useful if your goal is to eliminate internet failed logins. I, personally, think that it's mostly silly. I am able to ignore failed login attempts with gratuitious use of 'grep -v' when looking at logs. The only login attempts that you should care about is ones that succeed. :PAlthough if you are getting hit so hard that it's actually impacting your server then that is a real problem.
