What are you supposed to do if you’ve forgotten or lost your Mac password? Or can’t remember your Apple ID password when you attempted to login into your Mac ? Don’t panic, you still have a few other ways to reset and recover lost password on Macby resetting its password with the help of third-party software, please read on.

1. John the Ripper: Tool for Mac password cracking

John The Ripper is perhaps the best known password cracking (hacking) tools out there, and that’s why it will always be in our ‘concise top ten hacking tools’ category. Aside from having the best possible name, it works and is highly effective. John The Ripper is a part of the Rapid7 family of hacking tools. There are two versions you can choose from, the free version and the commercial “PRO” version.The commercial version optimized for performance and speed. For the average user, John The Ripper ‘open-source’ will work great, for the real hard-core user we’d certainly recommend the Pro Version.

Features of John The Ripper:

  • It is a fast password cracker
  • John The Ripper runs on various platforms 11,like Unix, Windows, DOS, BeOS, and OpenVMS, Mac OS
  • The actual usage procedure is quite easy
  • It provides a free version

2. THC Hydra : Multiple services supportive, Network authentication Mac PasswordCracker

THC Hydra, or simply ‘Hydra’, is another very popular and supper fast network password hacking tool. It can be used to crack passwords of different protocols including HTTPS, HTTP, FTP, SMTP, Cisco, CVS, SQL, SMTP etc. It will give you option that you may supply a dictionary file that contains list of possible passwords. It’s best when we use it in Linux environment.

Features of THC Hydra

  • Fast cracking speed
  • Available for Windows, Linux ,Solaris and OS X
  • New modules can be added easily to enhance features
  • Supportive with Brute force and dictionary attacks

3.Medusa : Speedy MacPassword Cracking Tool

Medusa is remote systems password cracking tool just like THC Hydra but its stability, and fast login ability prefer him over THC Hydra.

It is speedy brute force, parallel and modular tool. Software can perform Brute force attack against multiple users, hosts, and passwords. It supports many protocols including AFP, HTTP, CVS, IMAP, FTP, SSH, SQL, POP3, Telnet and VNC etc.

Medusa is thread-based tool, this feature prevent unnecessarily duplicate of information. All modules available as an independent .mod file, so no modification is required to extend the list that supports services for brute forcing attack.

Features of Medusa

  • Available for Windows, SunOS, BSD, and Mac OS X
  • Capable of performing Thread based parallel testing
  • Good feature of Flexible user input
  • Due to parallel processing speed of cracking is very fast

For Mac users, you can easily crack the forgotten password with 3 Mac password reset software mentioned above. For Windows user, we will recommend you the best free Windows password recovery program—Windows Password Recovery Tool. It is designed to recover, or reset lost user and administrator passwords on Windows 10/8.1/8/7/XP/Vista.

John the Ripper (JtR) is one of the hacking tools the Varonis IR Team used in the first Live Cyber Attack demo, and one of the most popular password cracking programs out there. In this blog post, we are going to dive into John the Ripper, show you how it works, and explain why it’s important.

Notes about hacking: Hacking is a pursuit of knowledge about systems, design, and humans. In this case, we are talking about software and operating systems.

Hacking is not necessarily criminal, although it can be a tool used for bad intentions. We advocate for ethical hacking. Stay in the light side of the Force.

How Does John the Ripper Work?

JtR supports several common encryption technologies out-of-the-box for UNIX and Windows-based systems. (ed. Mac is UNIX based). JtR autodetects the encryption on the hashed data and compares it against a large plain-text file that contains popular passwords, hashing each password, and then stopping it when it finds a match. Simple.

In our amazing Live Cyber Attack demo, the Varonis IR team demonstrates how to steal a hashed password, use JtR to find the true password, and use it to log into an administrative account. That is a very common use case for JtR!

JtR also includes its own wordlists of common passwords for 20+ languages. These wordlists provide JtR with thousands of possible passwords from which it can generate the corresponding hash values to make a high-value guess of the target password. Since most people choose easy-to-remember passwords, JtR is often very effective even with its out-of-the-box wordlists of passwords.

JtR is included in the pentesting versions of Kali Linux.

What is John the Ripper Used for?

JtR is primarily a password cracker used during pentesting exercises that can help IT staff spot weak passwords and poor password policies.

Here is the list of encryption technologies found in JtR:

  • UNIX crypt(3)
  • Traditional DES-based
  • “bigcrypt”
  • BSDI extended DES-based
  • FreeBSD MD5-based (linux and Cisco IOS)
  • OpenBSD Blowfish-based
  • Kerberos/AFS
  • Windows LM (DES-based)
  • DES-based tripcodes
  • SHA-crypt hashes (newer versions of Fedora and Ubuntu)
  • SHA-crypt and SUNMD5 hashes (Solaris)

That’s the “official” list. JtR is open-source, so if your encryption of choice isn’t on the list do some digging. Someone might have already written an extension for it.

How to Download John the Ripper

JtR is an open-source project, so you can either download and compile the source on your own, download the executable binaries, or find it as part of a penetration testing package.

The official website for John the Ripper is on Openwall. You can grab the source code and binaries there, and you can join the GitHub to contribute to the project.

JtR is available on Kali Linux as part of their password cracking metapackages.

Tutorials for Using John the Ripper

We are going to go over several of the basic commands that you need to know to start using John the Ripper. To get started all you need is a file that contains a hash value to decrypt.

If you ever need to see a list of commands in JtR, run this command:

Cracking Passwords

John the Ripper’s primary modes to crack passwords are single crack mode, wordlist mode, and incremental. The single crack mode is the fastest and best mode if you have a full password file to crack. Wordlist mode compares the hash to a known list of potential password matches. Incremental mode is the most powerful and possibly won’t complete. This is your classic brute force mode that tries every possible character combination until you have a possible result.

The easiest way to try cracking a password is to let JtR go through a series of common cracking modes. This command below tells JtR to try “simple” mode, then the default wordlists containing likely passwords, and then “incremental” mode.

You can also download different wordlists from the Internet, and you can create your own new wordlists for JtR to use with the –wordlist parameter.

If you want to specify a cracking mode use the exact parameter for the mode.

Word Mangling Rules

Mangling is a preprocessor in JtR that optimizes the wordlist to make the cracking process faster. Use the –rules parameter to set the mangling rules.

Viewing Your Output

When you want to see the list of passwords that you have cracked, use the –show parameter.

If your cracked password list is long, you can filter the list with additional parameters. You can also redirect the output using basic redirection in your shell. For example, if you want to see if you cracked any root users (UID=0) use the –users parameter.

Or if you want to show users from privileged groups use –groups.

Below is the JtR command from our Live Cyber Attack Webinar. In this scenario, our hacker used kerberoast to steal a Kerberos ticket granting ticket(TGT) containing the hash to be cracked, which was saved in a file called ticket.txt. In our case, the wordlist used is the classic rockyou password file from Kali Linux, and the command was set to report progress every 3 seconds.
