Infiltrating Wi-Fi Networks: Software and Techniques Without a Router

How to Protect Your Wi-Fi Network

Change your password regularly

Reasons for Periodic Password Changes:

1. Security: Changing your password regularly helps reduce the risk of hacking or unauthorized access to your account. While strong passwords are important, regular changes can reduce the risk of account misuse due to passwords being revealed or leaked.
2. Security Policy: Many online organizations and services implement a policy of changing passwords periodically as part of their security practices. This can help comply with security standards and reduce potential vulnerabilities.
3. Early Detection: Periodic password changes can help detect attacks that may have occurred without them being noticed, as attacks often take time to steal or guess passwords.
4. New Technology: Security technologies and encryption algorithms are constantly evolving. By changing your password regularly, you can ensure that your password is using the latest practices for protecting your account.

Replacement Frequency:

• Generally, it is recommended to change your password at least once every 3-6 months. However, this frequency may vary depending on your organization’s security policies or personal preferences.
• Some organizations may require password changes every 90 days or more frequently, depending on the sensitivity level of the data accessed by the account.

Strong Password Criteria:

1. Long: Try to have a password of at least 12 characters. The longer it is, the harder it is to predict or predict by a brute-force attack.
2. Character Combinations: Use a combination of uppercase and lowercase letters, numbers, and symbols. This will increase the complexity and strength of your passwords.
3. Don’t Use Personal Information: Avoid using personal information that is easy to guess, such as your name, date of birth, or words that are personally associated with you.
4. Don’t Use Common Words: Stay away from commonly used words or words that are easy to find in password dictionaries.
5. Random: Create passwords that look random and don’t directly relate to predictable words.
6. Using Phrases or Sentences: Using phrases or sentences that you remember easily but that others have a hard time guessing can help create passwords that are easy to remember but still strong.

Examples of Strong Passwords:

• 8Y$fH2!a4mW&
• B3ch$B1gTr3e$

Disabling WPS (Wi-Fi Protected Setup)

The WPS (Wi-Fi Protected Setup) feature on routers has significant security risks due to its potential to make it easy to set up a Wi-Fi connection. However, the main drawback of WPS is that it is vulnerable to brute-force attacks that can allow attackers to access Wi-Fi networks without having to know the actual password.

Some of the security risks of WPS include:

• Brute-Force Attack: An attacker can use the brute-force technique to guess the WPS PIN which by default only has 8 digits. By using tools such as Reaver or Bully, these attacks can be carried out in a relatively short period.
• PIN Attack: WPS PINs are often easy to guess or contained in widespread databases, making them vulnerable to attacks by trying several common PIN combinations.
• Vulnerability to DoS Attacks: Some WPS implementations can also be vulnerable to Denial-of-Service (DoS) attacks, which can disrupt the availability of Wi-Fi networks.

How to Disable WPS on a Router

To improve the security of your Wi-Fi network, it is recommended to disable the WPS feature on your router. Here are the general steps to disable WPS, although these procedures may vary depending on the make and model of your router:

1. Open a web browser and enter your router’s default IP address into the address bar (for example, 192.168.1.1 or 192.168.0.1). You will be asked to enter a username and password to log in to the router’s administration interface.
2. In the router’s administration interface, look for the option related to Wi-Fi Protected Setup or WPS. This can be found under wireless network settings or security.
3. Once you find the WPS option, choose to disable it. This is usually done by selecting the “Disable” or “Off” option next to WPS.
4. After disabling WPS, be sure to save the changes or confirm the settings before exiting the router administration interface.
5. To make sure the changes take effect, you may need to restart your router. This will ensure that all new settings are applied correctly.

Using WPA3

WPA3 (Wi-Fi Protected Access 3) is the latest security standard for Wi-Fi networks that offers several advantages over its predecessor, WPA2. Here are some of the key advantages of WPA3:

1. Protection Against Brute-Force Attacks: WPA3 introduces a stronger authentication method and is less vulnerable to brute-force attacks on Wi-Fi passwords. This makes it more difficult for attackers to guess or steal Wi-Fi passwords.
2. Stronger Encryption: WPA3 improves the encryption quality of data exchanged on Wi-Fi networks, making it more difficult for attackers to access or manipulate data transmitted over the network.
3. Enhanced Privacy Protection: WPA3 provides additional privacy protection for Wi-Fi networks by introducing individual encryption for every connected device, even in open or public networks.
4. Protection Against Offline Attacks: WPA3 improves protection against offline attacks by requiring attackers to be near a Wi-Fi access point (AP) during the authentication process.
5. Support for IoT and Smart Devices: WPA3 introduces a more secure mode of operation for IoT (Internet of Things) devices and smart devices, which are often vulnerable to attacks due to security flaws associated with weak configuration and authentication.

Steps to Upgrade to WPA3

Upgrading to WPA3 may require a few steps depending on your hardware (router) and connected device support. Here is a general guide to upgrading to WPA3:

1. Make sure that your hardware (router) supports WPA3. Many new routers have support for WPA3, but it’s worth checking the manufacturer’s documentation or website.
2. If your router supports WPA3 but doesn’t come with the latest firmware that supports this feature, update your router’s firmware to the latest version. This can usually be done through the router’s administration interface.
3. After updating the firmware (if required), log in to your router’s administration interface.
4. Look for the option to enable WPA3 in your security settings or wireless network. Typically, you’ll find this under network security settings or similar options.
5. After enabling WPA3 on your router, make sure that the connected Wi-Fi device also supports WPA3. Devices such as laptops, smartphones, and IoT devices should be able to select WPA3 as a security option when connected to a Wi-Fi network.
6. After configuring WPA3, test your device connections to ensure that all devices are properly connected and can access the internet with enhanced security.
