What is a Dictionary Attack?
A dictionary attack is a method used by hackers to crack passwords by systematically testing a list of potential passwords—commonly known as a “dictionary.” This list contains words that users frequently use as passwords, such as “123456,” “password,” “admin,” or even names and phrases.
Unlike brute force attacks, dictionary attacks are faster and more efficient because they skip random guesses and rely on the likelihood of human behavior.

How Dictionary Attacks Work
Here’s a breakdown of how a dictionary attack typically operates:
- Wordlist Selection: Attackers use precompiled lists of common passwords. These can include leaked password databases or custom-generated lists.
- Hash Matching: If passwords are stored as hashes, the attacker hashes each word from the list and compares it to the stored hashes.
- Automation: Tools like Hydra, Medusa, and John the Ripper automate the process—making it lightning fast.

Why Dictionary Attacks Still Work
Despite warnings, users continue to create easy-to-guess passwords. According to studies, over 50% of internet users reuse passwords across platforms. This makes dictionary attacks highly effective—especially when password complexity is minimal.

Defending Against Dictionary Attacks
The good news? You can defend against these attacks with basic security hygiene. Here’s how:
1. Use senhas fortes
Avoid dictionary words. Instead, use long, random combinations of characters.
2. Enable Two-Factor Authentication (2FA)
2FA significantly reduces the risk—even if your password is compromised.
3. Monitor Login Attempts
Enable alerts and auto-lockout after failed login attempts to stop attackers early.
