A brute force attack on your router It is a method that cybercriminals use to try to access your device, network or system by trying different password combinations until they find the correct one.
This technique is based on “trial and error.” The attacker subjects your device to a large number of access attempts in a short period of time using automated software.
The objective is to break security measures to obtain sensitive information, compromise connected devices or take advantage of your network resources for malicious purposes.
How a brute force attack works on your router
In order for a brute force attack to be carried out on your router, the following phases must occur:
-Scanning your network. The attacker searches for your router and other devices connected to the network. Identify if your computer model has vulnerabilities or if it uses factory settings or default usernames or passwords.
-Use of programs to test passwords. Once your device is found, the attacker uses automated software that tries a large number of password combinations. These types of programs send thousands of requests in a matter of seconds.
-Entry to the router. By guessing the correct password, access your router settings to commit improper activities.
-Settings on your network. The cybercriminal changes the security settings. In addition, it redirects Internet traffic to malicious sites, or even creates a “back door” to try to later access your network without you realizing it, potentially attacking other devices you have connected, such as security cameras, televisions or computers. .
-You can create a botnet. The attacker, through your router, can create a network of infected devices called a botnet that allows them to use your equipment to send large-scale attacks, such as a denial of service (DDoS) attack against other systems.
How to protect yourself from a brute force attack on your router
If you want to protect your router from a brute force attack you must do the following:
-Change your password. Do not keep the key that comes from the factory. Set a password that is strong and that combines upper and lower case letters, numbers and symbols so that it is not so easy to guess.
-Update the router firmware. Updating the firmware of your Wi-Fi router frequently is very useful to correct possible vulnerabilities in your equipment.
-Limits remote administration. This way no one will be able to access your device outside the local network and it will not be a gateway for attackers.
-Create a network of guests. You can use it specifically with less secure devices, be it smart speakers, security cameras, among others.
-Activate two-factor authentication. With it, you will add an additional layer of security that will make it difficult for attackers to enter your router if they guess the password.
-Configure the limits of failed attempts. Set limits on failed login attempts before temporarily locking the account. This will help you stop brute force attacks since the attacker won’t be able to keep trying passwords constantly.
-Monitor your network daily. You must be aware of your network activity. If you notice an unusual increase in bandwidth usage or devices you don’t know about, it could be a sign of a brute force attack.
