What is a Brute Force Attack?
A brute force attack refers to hackers using a trial-and-error method to gain access to an account. This may involve breaking a password or personal identification number (PIN), depending on the context. Most brute force attacks are automated, making businesses of all sizes potential targets. Brute force attacks are the most common and direct type of cyberattack. They are used to crack passwords to gain access to a website's backend and obtain crucial information.
How Does a Brute Force Attack Work?
Understanding brute force attacks and how they operate isn't complex; what's more challenging is how to protect yourself from them.Any site with a login page (or any form of password protection) is a potential target for such attacks.
Content Management System (CMS) admin pages that are most frequently targeted include:
- WordPress wp-admin or wp-login.php login pages
- Magento /index.php or admin pages
- Joomla! administrator
- vBulletin admin control panel
- Various other common login pages of websites
When attackers aim to access a website, user account, or any other encrypted information, they first need to crack or unlock that information.
This process begins with trying different possible combinations of passwords and continues until they crack the password of the target they wish to access. There are thousands of potential password combinations for just one account. The standard minimum password length is eight characters.
How Can We Prevent Brute Force Attacks?
Simple measures any user can take against brute force attacks include:
- Adding special characters
- Reducing the number of login attempts
- Using CAPTCHA
- Enabling two-factor authentication
- Alphanumeric password combinations
- A longer password (beyond the standard 8 characters)
- Combining uppercase and lowercase letters
