Spear phishing targets a particular individual and tries to gather as much personal information as possible before the attack.There are different types of phishing tailored for a particular situation, so weвЂ™ll look at the few common ones:

In the end, password-extracting software is installed automatically or the user enters his account details into a look-alike website. The methods for doing so usually involve sending some important and official-looking email that warns to take action before itвЂ™s too late. Phishing is the most popular technique that involves luring the user into clicking on an email attachment or a link that contains malware. There are many cases when these are combined together for greater effect.

Now letвЂ™s discuss the most popular password cracking techniques. Prepare the hashes for a selected cracking tool ThatвЂ™s why using a password manager, biometric data (which has its cons too) or adding a second factor will make most of the cracking methods below useless.ДЄ typical password cracking attack looks like this:

ThatвЂ™s especially the case if a user creates a weak password, reuses it, and stores its plaintext copy somewhere online. While passwords are a very popular account security tool, they arenвЂ™t necessarily the safest option. If that fails, there are plenty of other password cracking techniques to try. As long as the human is the weakest link of any security system, targeting her or him is the best bet. More often than not, that method is phishing, described in detail below. Naturally, hackers want to use the easiest available method for password cracking. Top-8 password cracking techniques used by hackers Unfortunately, there are still some services that store unencrypted or weakly-encrypted passwords on their servers. Some methods of password cracking become significantly more difficult if your password uses salting or key stretching. ThatвЂ™s why most password hash functions use key stretching algorithms, which increase the resources (and, therefore, time) needed for a brute-force attack. ItвЂ™s easy to try different hashed passwords at a high rate when using a GPU or botnet. This takes a password and runs it through a one-way encryption cipher, creating whatвЂ™s known as a вЂњhash.вЂќ The server stores the hash-version of the password.

However, now most passwords are stored using a key derivation function (KDF). If the password is stored as plaintext, hacking the database gives the attacker all account information. A brute-force attack where all possible combinations are checked is also password cracking. This doesnвЂ™t have to be a sophisticated method. Password cracking means recovering passwords from a computer or from data that a computer transmits. But before we go down to details, letвЂ™s discuss what password cracking is. Nowadays, you can even find specialized password cracking tools, which donвЂ™t have to be used only for ill purposes.

WeвЂ™ll be discussing various password cracking techniques in this article. Password cracking is one of them вЂ“ involves using various computational and other methods to break through the password authentication step. вЂњshadowвЂќ file located at /etc/shadow contains the SHA encrypted password of each of the users found in passwd file.ДЇor this lab, we have a passwd & shadow file from a remote system stolen with other tools (explained within this series) located in the Desktop folder.There are many ways to hack into an account. In unix/linux вЂњpasswdвЂќ file located at /etc/passwd contains all user information. For that first, we have to understand the files containing the authentication information. In this tutorial, weвЂ™ll look at breaking a week Unix password. Output tab shows the result of the attack once passwords get cracked.Settings allow you to edit the main settings for the john engine like the path to the binaries, timing etc.Statistics tab shows the current statistics once the attack has started.(Default, Incremental, Wordlist mode etc).
