A dictionary attack is based on trying all the strings in a pre-arranged listing. Such attacks originally used words found in a dictionary (hence the phrase dictionary attack); [2] however, now there are much larger lists available on the open Internet containing hundreds of millions of passwords recovered from past data breaches. [3]
One of the modes John can use is the dictionary attack. [6] It takes text string samples (usually from a file, called a wordlist, containing words found in a dictionary or real passwords cracked before), encrypting it in the same format as the password being examined (including both the encryption algorithm and key), and comparing the output to the encrypted string.
A directory harvest attack (DHA) is a technique used by spammers in an attempt to find valid/existent e-mail addresses at a domain by using brute force. [1] The attack is usually carried out by way of a standard dictionary attack, where valid e-mail addresses are found by brute force guessing valid e-mail addresses at a domain using different permutations of common usernames.
A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). [1] Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the ...
More common methods of password cracking, such as dictionary attacks, pattern checking, and variations of common words, aim to optimize the number of guesses and are usually attempted before brute-force attacks. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover ...
The Secure Remote Password protocol (SRP) is an augmented password-authenticated key exchange (PAKE) protocol, specifically designed to work around existing patents. [1]Like all PAKE protocols, an eavesdropper or man in the middle cannot obtain enough information to be able to brute-force guess a password or apply a dictionary attack without further interactions with the parties for each guess.
Hashcat offers multiple attack modes for obtaining effective and complex coverage over a hash's keyspace. These modes are: Brute-force attack [7] Combinator attack [7] Dictionary attack [7] Fingerprint attack; Hybrid attack [7] Mask attack [7] Permutation attack; Rule-based attack [7] Table-Lookup attack (CPU only) Toggle-Case attack [7]
