Dictionary Attacks

Last updated
Dictionary attacks are a common type of password attack that relies on a predefined list of words, phrases, or commonly used passwords, known as a "dictionary." In this attack, the attacker systematically tries each word from the dictionary as a possible password to gain unauthorized access to a system or account.
The attack is based on the assumption that many users choose weak passwords that are easy to guess. The dictionary can include common words, names, patterns, and commonly used combinations. The attacker uses automated tools that iterate through the dictionary, trying each word as a password until a successful match is found.
Rockyou is a widely known and extensively used wordlist in the field of password cracking and security testing. It gained its popularity due to the large number of passwords it contains, derived from a breach of the Rockyou website in 2009. The wordlist consists of millions of commonly used passwords, dictionary words, and combinations that users often use to secure their accounts.
Security professionals and ethical hackers often leverage the Rockyou wordlist during password auditing and penetration testing to identify weak passwords and assess the strength of an organization's security. It serves as a valuable resource for testing the effectiveness of password policies and highlighting the importance of using strong, unique, and hard-to-guess passwords.
rockyou.txt contains 14,341,564 unique passwords, used in 32,603,388 accounts.
