Dictionary attack facts for kids
A dictionary attack is a way that computers try to guess a secret code, like a password or a username. Imagine someone has a huge list of common words, names, and phrases. A dictionary attack uses a computer program to try every single word from that list, one by one, until it finds the correct one.
This method is called a "dictionary attack" because the list of words often comes from a dictionary, but it can also include lists of popular passwords, common names, or even phrases. It's like trying every key on a giant keyring until one opens the lock!

What is a Dictionary Attack?
A dictionary attack is a type of cyberattack where a computer program tries to break into a system by guessing passwords. Instead of guessing randomly, it uses a special list of words and phrases. This list is often called a "dictionary" because it contains many common words, just like a real dictionary.
How Does a Dictionary Attack Work?
When you try to log into a website or an app, you usually type a username and a password. A dictionary attack works by having a computer program automatically try thousands or even millions of different words from its list as the password.
- The attacker gets a list of possible passwords. This list can be very long.
- The computer program then tries each word from the list as a password for a specific account.
- If one of the words matches the real password, the attack is successful, and the attacker gains access.
Why Are They Used?
Dictionary attacks are popular because many people use simple or common words as passwords. If your password is "password," "123456," or your pet's name, it's likely to be on one of these lists. This makes it easier for attackers to guess.
Protecting Yourself from Dictionary Attacks
It's important to protect your online accounts from these kinds of attacks. Here are some tips:
- Use Strong Passwords: Make your passwords long and complex. Don't use words that can be found in a dictionary.
- Mix It Up: Combine uppercase and lowercase letters, numbers, and special symbols (like !, @, #, $). For example, "MyP@ssw0rd!" is much stronger than "Mypassword".
- Make Them Unique: Use a different password for each important account. If one account is hacked, your others will still be safe.
- Two-Factor Authentication (2FA): This adds an extra layer of security. Even if someone guesses your password, they would also need a code sent to your phone or email to log in.
- Password Managers: These tools can help you create and store strong, unique passwords for all your accounts.
