Home Wi-Fi Vulnerabilities

There are many ways for people to get unauthorized access to your home wireless network. At best, someone might be trying to piggyback on your connection for their Internet needs. At worst, it can mean severe danger, including theft of sensitive information and losing access to your devices.

There are many ways for threat actors to find your home Wi-Fi password, especially if you have set a weak one

For starters, many users do not even change the default access passwords of their home routers. This is the first thing hackers usually try. In many cases, it is enough for them to gain access to the routers, view and change the settings, and access the wireless network.

In fact, according to a survey, 79 percent of respondents have a weak Wi-Fi password set up at home. With weak passwords, it can be relatively easy for hackers to set up a brute force attack, arriving at your password eventually. 

They might even resort to devious social engineering to retrieve your password. Birthdays, important dates, names, and other easily discoverable personal information are bad passwords.

More enterprising hackers, equipped with the right tools, can resort to methods like packet sniffing to capture and study your wireless data packets and use that data to hack your passwords.

If your password gets hacked, you are exposed to several dangers, including:

Performance Issues: If you have one or more unauthorized people sharing your Internet connection and hogging your bandwidth, you have less left. You will see slower speeds and connectivity issues.
Malware: With access to your home Wi-Fi, threat actors can easily infect your devices with malware. This can be used to steal sensitive data, which puts you at serious risk of identity theft.
Hacked Devices: Since your devices are connected to your home Wi-Fi, breaching them allows threat actors to access them. This can mean access to your files, passwords, cameras, and microphones, a significant breach of privacy.
Data Theft: This is something to be wary of in the best times. With access to your personal and sensitive data, hackers can easily steal your identity, perform financial transactions on your behalf, and even sell your personal information on the dark web.
Other Threats: Once in control, hackers can use your home Wi-Fi and an internet connection to commit other unethical and even illegal acts, which can directly be tied to your IP address, leaving you vulnerable to legal trouble.

Keeping these threats in mind, it is always a good idea to adopt specific best practices with your home Wi-Fi and remain vigilant for unauthorized activity. You can take immediate action when you spot anything out of the ordinary.

First, you should closely examine your home network, identify its vulnerabilities, and plug all the holes you can.

Securing your Home Wi-Fi

The better you secure your home wireless network, the harder it becomes for any malicious parties to gain access to your connection password and data. From the outset, the focus should be on setting up your network correctly so that the most significant points of vulnerability can be adequately protected.

Here are a few critical steps.

Change the Default Password of Your Router

Every Wi-Fi router comes with a default username and password out of the box, which you are supposed to use while setting it up at home. You are supposed to change this default password during the initial setup. However, a lot of users do not bother to do this. 

Consequently, this is one of the first things hackers can try while trying to gain access to your router. Default passwords for most major brands and models of routers are readily available on the Internet. 

Change the password of your router interface the first time you log on to it, and select a long, complex, and secure password.

Create a Secure Password

When you set up your home wireless network, you will notice that every network needs a password or a wireless key once you enable security on the network. This passphrase needs to be something difficult for hackers to get their hands on. 

Easy passwords like names, dates, birthdays, and locations should never be considered. Similarly, familiar words and phrases are also out as these are easy to hack using dictionary brute force attacks. 

For the best results, you should have a reasonably long password comprising lowercase and uppercase letters, numbers, and special characters.

Choose the Right Protocol

When setting up your home Wi-Fi, you will notice that your router offers protection and encryption. This is true for most modern routers. You should see options like WEP, WPA-PSK, WPA2, and WPA3. Right off the bat, do not choose the now obsolete WEP protocol. 

WPA2 and WPA3 are the best choices, and if all your connected devices support WPA3, this is the way to go. Otherwise, stick to WPA2 and never change the encryption protocol to something less secure. 

If you have legacy devices that only support older protocols, upgrading is the best way forward instead of compromising your network security.

Create a Guest Network

Often, having to share information about your home Wi-Fi when you have guests at home can be a critical point of vulnerability. Good practice dictates keeping the guests on a separate network that does not have access to your devices. 

This can be easily achieved by creating an independent guest network and closing it off from the rest of your local network. All you need for the guest network is Internet access. 

When you have guests over, share the details of this network, and your primary home network will not be disturbed. This is also beneficial if a guest has a device already infected with malware and is looking for more hosts. 

Keep your Router Updated

Often, older router firmware can be vulnerable to specific attacks from hackers. Router manufacturers routinely release firmware upgrades meant to patch these security holes. 

Once you install and set up your router, you must be on the lookout for firmware updates. When one becomes available, follow the recommended procedure from the manufacturer to download and install it on your router. Do this regularly for the best results.

Never use WPS

WPS or Wi-Fi Protected Setup is a convenience feature provided in many routers. It comes as a physical button or switch in the router, which you can turn on to make it easy for a device supporting WPS to connect to the router

Similarly, there might be settings relevant to WPS in your router settings. 

While this might be convenient to use in some cases, it is a security vulnerability. A router with WPS enabled is much easier to break into for hackers. Therefore, spend a little extra time to pair your devices if needed and choose not to turn on WPS on your router.

Turn Off Router Features

Certain router features are meant for ease of use and convenience. However, these also weaken your security. It is a good idea to turn off such services permanently. 

A good starting point is the UPnP or Universal Plug and Play feature, which lets different software open ports on your router for easy Internet access. Another good candidate is the remote management feature that enables you to access and manage your router settings over the Internet. 

These leave open loopholes and allow enterprising hackers to enter your home network. Find these settings in your router admin panel and disable them permanently.

Access Control and Monitoring

Access control for your primary home wireless network is essential as you do not want any unauthorized device ever to gain connection. While many routers have multiple means to achieve this, one of the easiest ways to control access is to lock devices down by MAC address, a unique hardware address in all your connected devices. 

Once all the devices you want are connected to the router, you can configure it to reject any connection attempts from a different MAC address than the ones already connected. 

This provides an additional layer of security over and above your Wi-Fi password. Another great way to guard your main home network is to hide the SSID or network name. Typically, this is advertised for all to find. 

Hiding it means that only people who know the exact name of the network should be able to log into it. Monitor your network regularly, looking at connected devices and logs to see if any unauthorized attempts have been made to sign on.

Firewalls and Malware Protection

In order to remove all the security loopholes, you need multiple layers of protection. This means securing not just your router but also all of your connected devices. 

Most routers come with built-in firewalls that you can activate. Once active, these can protect you from various network-based attacks, including code injection and denial of service attacks. 

You can pair that with competent malware protection and removal software installed in all the devices that scan for malware and alert you if anything gets infected. Keep your anti-virus software regularly updated with the latest virus definitions.

Use a VPN

Using a VPN is one way to protect your data even if your Wi-Fi has been breached. This creates a secure, encrypted network between your devices and the internet so that even with advanced methods like packet sniffing, any data hackers might get will be useless to them. 

Many routers will allow you to set up a VPN connection on the router software and have system-wide VPN protection for the whole home. Using a modern VPN protocol like OpenVPN and WireGuard helps you maintain excellent connectivity and speed while taking complete advantage of the protection a VPN has on offer.

Upgrade your Router

If your router only comes with basic features, it might not provide enough protection for your home network. Consider buying a more advanced router with better security features. 

This one-time investment can provide you with better protection for years to come. For more granular control over your network, consider feature-rich router frameworks like DD-WRT and OpenWRT if you have a supported router. 

Alternatively, create one from scratch using an old computer using a solution like pfSense.
