Brute force and dictionary attacks in Cybersecurity - Mini Project: Build & Apply

Understanding Brute Force and Dictionary Attacks

📖 Scenario: You are learning about common methods hackers use to guess passwords. Two common ways are brute force attacks and dictionary attacks. Understanding these helps you protect your accounts better.

🎯 Goal: Build a simple example that shows how brute force and dictionary attacks try passwords from a list to find the correct one.

📋 What You'll Learn

Create a list of possible passwords to try

Create a variable to hold the correct password

Write a loop that tries each password from the list

Add a check to stop when the correct password is found

💡 Why This Matters

🌍 Real World

Understanding how attackers guess passwords helps you create stronger passwords and protect your accounts.

💼 Career

Cybersecurity professionals use knowledge of these attacks to build better security systems and educate users.

1

Create a list of possible passwords

Create a list called passwords with these exact strings: "1234", "password", "letmein", "admin", "welcome".

Cybersecurity

# Create the list of passwords
# Your code here

Need a hint?

Use square brackets [] to create a list and separate items with commas.

2

Set the correct password

Create a variable called correct_password and set it to the string "letmein".

Cybersecurity

passwords = ["1234", "password", "letmein", "admin", "welcome"]
# Set the correct password
# Your code here

Need a hint?

Use an equals sign = to assign the string "letmein" to the variable.

3

Try each password in the list

Write a for loop using the variable attempt to go through each password in the passwords list.

Cybersecurity

passwords = ["1234", "password", "letmein", "admin", "welcome"]
correct_password = "letmein"
# Loop through each password attempt
# Your code here

Need a hint?

Use for attempt in passwords: to loop through the list.

4

Check if the password is correct and stop

Inside the for loop, add an if statement to check if attempt equals correct_password. If yes, add a comment # Password found and use break to stop the loop.

Cybersecurity

passwords = ["1234", "password", "letmein", "admin", "welcome"]
correct_password = "letmein"
for attempt in passwords:
    # Check if attempt matches correct_password
    # Your code here

Need a hint?

Use if attempt == correct_password: and inside it write break to stop the loop.
