Brute-force attack: How to defend against digital intruders

Imagine this: a burglar stands at your office door with a huge bag full of tens of thousands of keys. He tries them out one by one. He doesn't stop, he doesn't get tired, and he keeps going until he finds the right key. That is exactly what a Brute-force attack is, but at digital speed.

At Mediawax, we see that these attacks occur thousands of times an hour on websites worldwide every day. How do you ensure that your door stays locked?

What is a Brute-force attack?

A Brute-force attack is a method in which hackers use automated software to guess billions of combinations of usernames and passwords.

Because computers are becoming increasingly faster, simple passwords like Welkom01 or Wachtwoord123 can nowadays be cracked within seconds. Hackers often target login pages for content management systems (such as WordPress), FTP accounts, or email portals.

How do you defend against it? (The 4 locks on the door)

1. Use strong, unique passwords

This sounds obvious, but it is the most important barrier. A 12-character password with symbols and numbers is exponentially harder to crack than a shorter word. Use a password manager (such as Bitwarden or LastPass) so that you never reuse the same password.

2. Implement Multi-Factor Authentication (MFA)

This is the absolute "game changer". Even if a hacker guesses your password, they cannot get in without the unique code on your smartphone. MFA blocks almost 99% of all automated login attempts.

3. Limit the number of login attempts (Login Throttling)

At Mediawax, we often configure servers so that an IP address is temporarily blocked after, for example, 3 or 5 incorrect attempts. This makes brute-forcing impossible, because the "intruder" has to wait each time. 4. Change your default login path

By default, hackers look for jouwsite.be/wp-admin or jouwsite.be/admin. By changing this URL to something unique, you make your website invisible to most automated bots.

Why Mediawax chooses proactive security

We do not leave security to chance. By using firewalls that immediately recognize and block suspicious behavior, we ensure that your website remains an impenetrable fortress.

Conclusion

A brute-force attack is a matter of the hacker's persistence. By making it technically impossible and time-consuming for them, they quickly retreat to an easier victim.
