Dictionary attack list
Trying to test the security of your Instagram account? A dictionary attack is one of the easiest way to do it. This script features:. For more information about this tool, please visit the official repository at Github here. As first step, you need to download the Instainsane repository in some directory of your Kali Linux system.
Proceed to clone the repository with the following command:. Then, switch to its directory and provide execution permissions to the Instainsane and Install scripts:. The Instainsane script requires basically Tor as a dependency, so you will need to have Tor installed on your system. Tor is short for The Onion Router thus the logo and was initially a worldwide network of servers developed with the U. Navy that enabled people to browse the internet anonymously.
Now, it's a non-profit organization whose user agent phone model purpose is the research and development of online privacy tools. The Tor network disguises your identity by moving your traffic across different Tor servers, and encrypting that traffic so it isn't traced back to you.
Anyone who tries would see traffic coming from random nodes on the Tor network, rather than your computer. Proceed to run the install script with the following command:. Finally, after installing the dependencies, just run instainsane with the command line executing the following command:. This will start instainsane and it will prompt for the username of the instagram account that you want to attack.

Then, as mentioned the attack will start and won't stop until the list of passwords ends or you stop it. You can pause it as well and store the session, so the next time you start it, it will start in the same place where you left it before.

With Brute Force Attack any type of password with any string lengthA dictionary attack is a method of breaking into a password-protected computer or server by systematically entering every word in a dictionary as a password. A dictionary attack can also be used in an attempt to find the key necessary to decrypt an encrypt ed message or document.
Dictionary attacks work because many computer users and businesses insist on using ordinary words as passwords. Dictionary attacks are rarely successful against systems that employ multiple-word phrases, and unsuccessful against systems that employ random combinations of uppercase and lowercase letters mixed up with numerals. In those systems, the brute-force method of attack in which every possible combination of characters and spaces is tried up to a certain maximum length can sometimes be effective, although this approach can take a long time to produce results.
Vulnerability to password or decryption-key assaults can be reduced to near zero by limiting the number of attempts allowed within a given period of time, and by wisely choosing the password or key.
For example, if only three attempts are allowed and then a period of 15 minutes must elapse before the next three attempts are allowed, and if the password or key is a long, meaningless jumble of letters and numerals, a system can be rendered immune to dictionary attacks and practically immune to brute-force attacks.
A form of dictionary attack is often used by spammers. A message is sent to e-mail addresses consisting of words or names, followed by the at symbolfollowed by the name of a particular domain.

The list of passwords that we recover using the attack is a text file in which each line contains a user account name followed by a password. There are two possible line formats: the first one contains an unsalted password while the second contains a salted password along with the salt.
When a salt is used, it is simply concatenated together with the passwords as follows: salt password. The attack simply reads the dictionary line by line and computes 6 different possible hashed passwords for the word contained in each line.
These 6 possible hashes are compared to each of the passwords contained in the password. If there is a match, we recovered a password. If not, we simply keep reading the dictionary line by line. Note that the salts used in salted hashes are the ones includes in the password.
To run the attack, simply compile and run the DictionaryAttack. All paths are hardcoded in the file so you will need to update them before you compile the source code. Note that this attack is a simple example and could be made far more efficient using various strategies.
One of them would be to precompute the possible hashes before checking the password list for matches. Since our password list and dictionary are fairly small in this example, I did not implement this feature.

A dictionary attack attempts to defeat an authentication mechanism by systematically entering each word in a dictionary as a password or trying to determine the decryption key of an encrypted message or document. Dictionary attacks are often successful because many users and businesses use ordinary words as passwords.
These ordinary words are easily found in a dictionary, such as an English dictionary. The most common method of authenticating a user in a computer system is through a password. This method may continue for several more decades because it is the most convenient and practical way of authenticating users.
However, this is also the weakest form of authentication, because users frequently use ordinary words as passwords. Antagonistic users such as hackers and spammers take advantage of this weakness by using a dictionary attack. Hackers and spammers attempt to log in to a computer system by trying all possible passwords until the correct one is found. Two countermeasures against dictionary attacks include:. Dictionary attacks are not effective against systems that make use of multiple-word passwords, and also fail against systems that use random permutations of lowercase and uppercase letters combined with numerals.

Techopedia explains Dictionary Attack The most common method of authenticating a user in a computer system is through a password. Two countermeasures against dictionary attacks include: Delayed Response: A slightly delayed response from the server prevents a hacker or spammer from checking multiple passwords within a short period of time.
Account Locking: Locking an account after several unsuccessful attempts for example, automatic locking after three or five unsuccessful attempts prevents a hacker or spammer from checking multiple passwords to log in.

Cybersecurity Concerns Rise for Remote Work.In cryptanalysis and computer securitya dictionary attack is a form of brute force attack technique for defeating a cipher or authentication mechanism by trying to determine its decryption key or passphrase by trying hundreds or sometimes millions of likely possibilities, such as words in a dictionary.
A dictionary attack is based on trying all the strings in a pre-arranged listing, typically derived from a list of words such as in a dictionary hence the phrase dictionary attack. Dictionary attacks often succeed because many people have a tendency to choose short passwords that are ordinary words or common passwords, or simple variants obtained, for example, by appending a digit or punctuation character.
Dictionary attacks are relatively easy to defeat, e. It is possible to achieve a time—space tradeoff by pre-computing a list of hashes of dictionary words, and storing these in a database using the hash as the key. This requires a considerable amount of preparation time, but allows the actual attack to be executed faster.
The storage requirements for the pre-computed tables were once a major cost, but are less of an issue today because of the low cost of disk storage. Pre-computed dictionary attacks are particularly effective when a large number of passwords are to be cracked. The pre-computed dictionary need be generated only once, and when it is completed, password hashes can be looked up almost instantly at any time to find the corresponding password.
5 Types of Dictionary Attacks! (Short Intro)
A more refined approach involves the use of rainbow tableswhich reduce storage requirements at the cost of slightly longer lookup-times. See LM hash for an example of an authentication system compromised by such an attack. Pre-computed dictionary attacks, or "rainbow table attacks", can be thwarted by the use of salta technique that forces the hash dictionary to be recomputed for each password sought, making precomputation infeasible, provided the number of possible salt values is large enough.
