It is true that hackers can access your system over your WiFi connection. However, there is no reason to worry about it while surfing the internet. Simple actions can help you prevent security breaches. To do this, you must first determine whether the network connection has been compromised.

How Can I Tell If A Network Connection Has Been Hack?

To determine whether a hacker has gained access to your system through the network connection, you can check the following things:

  • The speed is much slower since your network consumption is much more than usual.
  • abrupt removal of any malware or an antivirus application.
  • Unexpected and unusual behaviour on your system, such as erratic cursor movement, new files, applications, etc. Hackers can access your data system, misuse or manipulate it, download malware or other programmes, and more.
  • Your browser’s default homepage changing could be the consequence of a hacker incursion. This occurs as a result of the browser’s page redirect. In order to steal any valuable data, the hackers occasionally divert the visitor to a phone page.
  • a Programme or piece of software asking access to your network.

Check for these indicators if you’re unsure and keep wondering, “Can someone hack my computer using WiFi?”

How WiFi Allows A Hacker To Access Your Computer System

Hackers will utilize DNS (Data, Name, System) Hijacking to access your WiFi router when they are within your WiFi range. The MITM (Man In The Middle) assault is another name for it. The connections between your computer and router are disrupted by a hacking system, which collects sensitive information like passwords, user names, emails, account numbers, pins, etc.

If hackers are outside the range of your WiFi, they employ a different tactic. Here are a few instances of how cybercriminals can access your computer. Read on to find out if your computer may be hacked via WiFi and how to protect it from such assaults.

Computer Hacking Using Local WiFi

If your device is linked to a local network, nearby hackers may be able to access it. The majority of public networks are unsafe and fairly simple to sabotage. You’ve connected your gadget to a free public network, therefore the chance of a hacking attempt is quite real.

Connecting to WiFi that has previously been compromised at your place of business or from a neighbour is another way your device could be taken over. Your gadget becomes a simple target for the hacker as a result.

Any WiFi network that has been compromised will have all types of devices linked to it under assault. It could be a tablet, smartphone, laptop, computer, iPhone, or iPad. A hacker may be able to access your device once they have physical access to the same WiFi as you do.

Attack by a Man in the Middle

Attacks known as “man-in-the-middle” (MITM) allow hackers to listen in on a communication between two hosts. The “man-in-the-middle” attack happens between two hosts who are interacting legally. It enables the online criminal to covertly join discussions that they are not permitted to access through normal channels.

You must first understand how your computer connects to the WiFi connection in order to understand what a man-in-the-middle attack is. A WiFi router is used by every DSL, cable, and fiber-optic WiFi user to connect to the network. Through the router, data is transferred back and forth between your computer and the internet. Below is a thorough explanation of this procedure:

  • To connect to the internet, the computer will identify the local WiFi router.
  • Every computer has a network card that can be recognized by its unique MAC address. The router will communicate its specific MAC address to the computer when a user provides the right password. As a result, both the router and the PC have access to each other’s MAC addresses.
  • All internet traffic will subsequently be routed through the router after your computer has the router’s address.

Hackers must connect to an accessible local WiFi router in order to learn the router’s MAC address in order to access your data via WiFi. The MAC address of the hacker’s machine is then changed to the MAC address received from the router.

In this manner, the hacker’s device with the same address will receive all information from the devices connected to that router. The hacker serves as Man in the Middle as a result.

With the aid of particular data collecting techniques, the hacker acting as a middleman will be able to see all the information transferred and received. All of the user’s personal information, including URLs and user IDs, passwords, and numbers, will be viewable and saved on the hacker’s computer.

The hacker may also stop users’ sessions and reroute them to false websites. For instance, the hacker could alter the account number when a user is transferring money to another account in order to divert the funds to a different account.

Can someone hijack my computer using WiFi? searches can be seen by the hacker if your WiFi is actually compromised. Make careful to use a website with a secure browser protocol, such as “HTTPS” rather than “HTTP,” to protect yourself against cyberattacks.

The “s” in HTTPS stands for a secure connection that encrypts all data sent and received, typically rendering it unusable by hackers. A website is considered secure if it has a padlock icon next to the URL. An HTTP connection, however, does not encrypt the data, allowing a hacker’s access to it simple.

How to Crack the Router

When: A cybercriminal can easily hack your router because of:

  • Your router is not password-protected.
  • Your router’s default password remains the same, or it has a common password (such 12345678).
  • The router uses a WEP authentication mechanism, which is an obsolete technology (Wired Equivalent Privacy).

Changing your router’s login credentials is the first step in protecting it against a cyberattack. Try to create a lengthy, unique password. Your password’s complexity increases with the number of characters it contains.

It’s advised to use a password with at least 15 to 20 characters. Additionally, changing the default SSID (Router or network name) can make it easier for the hacker to determine the sort of router you are using. It is advisable to use longer, trickier names because they increase the WPA security of your router.

An outdated router protocol, like WEP, can be quickly and readily hacked by a would-be hacker. Additionally, WPS (Wireless protected setup) is somewhat safe, but a hacker in the vicinity of your network can simply access it. If the credentials are strong, a WPA (Wireless Protected Access) connection is a far more secure choice.

However, WPA using the TKIP encryption technique is also somewhat vulnerable to cyberattacks. The most safe wireless security methods are currently WPA3 and WPA2 (AES encryption algorithm).

For improved authentication strength, users of routers that support WEP, WPS, and WPA should update, if at all possible, to WPA2 or WPA3.

Cybercriminals won’t break into your system connected to the router using WPA or more advanced WPA protocols unless you are a billionaire or famous person. Keep in mind that these sophisticated techniques are not completely secure from online hackers. However, it takes a lot of resources to breach such a secure link.

How To Determine If Your Router Has Been Hacked

The most important indication that a router has been compromised is the presence of an unknown device connected to the public WiFi network. The presence of such a gadget may prompt you to consider whether my machine is vulnerable to WiFi hacking.

You can quickly identify a hacker’s equipment if your router permits viewing linked devices. Disconnect all unidentified devices by visiting the router’s settings.

Downloading a network scanning application is an additional choice. These Programmes allow you to view connected devices and search for any exposed, open ports. Turn off capabilities like remote access, screen sharing, etc. and remove all unauthorized devices.

How To Prevent A MITM Assault

Are you still concerned that someone could hack your PC using WiFi? Instead of handling ongoing MITM assaults, try to take proactive actions to stop them from happening in the first place. Understanding your surfing patterns and identifying potentially hazardous websites are necessary for maintaining a secure network. Here are a few best practices for shielding your browsing from MITM attacks.

Login Information

As was previously said, in order to thwart a cyberattack, you must configure a long and secure password as well as a special network name (SSID).

Router Firmware and Protocol

For improved connection security, disable WEP and WPS and switch to WPA, WPA2, or WPA3 protocols. Install any router firmware upgrades that are available from the maker’s website.


On public networks, it is impossible to scan for and find unusual gadgets, unlike in private networks. In this case, a virtual private network can protect your device from a cyberattack (VPN). You can search safely using a VPN service because it encrypts your data.

To a hacker connected to that public network, the encrypted data will appear to be random nonsense going back and forth. Because of this, the hacker won’t be able to obtain your login information or the URLs you’re using.

Make sure to take the following factors into account while choosing VPN software for ensuring acceptable security:

  • Choose a VPN programme with the fastest speed possible.
  • Version that costs money: Opt for commercial VPN software to access the best features rather than a free VPN.
  • Check the reputation of the VPN provider before using it. VPN acts as a man-in-the-middle by conducting searches on your behalf. Therefore, the VPN service provider needs to be trustworthy enough to protect your data.
  • Select a VPN programme that is compatible with all of your devices for compatibility.

Always use an HTTPS browser when searching. Since HTTP is an insecure browser, hackers can see your login information in plain text. Since HTTPS is secured, a secure search is guaranteed. In order to compel HTTPS websites when browsing, browser plug-ins are installed.

Authentication with public keys

At various points along the network, a public key authentication is used to verify that your connection or message is genuine.

Remote computer hacking

Someone who is within your wi-fi range can hack your computer. The question of whether attackers can remotely hijack your home WiFi from a distance comes to mind next.

Without a doubt! Even if the hackers manage to guess your home WiFi password, they are only able to access it within a 300-foot radius. In most cases, turning off your computer will prevent hackers from gaining access. However, there are a number of methods they can access your computers from a distance, including ransomware and spyware.

The same thing happened to Jeff Bezos. Jeff unintentionally downloaded spyware onto his phone from a fake WhatsApp message. His personal data started being sent to a server in another nation by this spyware.

Similar spyware can put us at risk if it is installed on our computers and other devices. By granting remote access to the device, this virus enables hackers to take control of it. Additionally, the spyware may be a keylogger.

When you use a computer, a keylogger captures each key you press. Your login information, including passwords, pins, and credit card numbers, will all be available to the hacker in this scenario. A VPN or HTTPS will be useless in this circumstance. Installing firewall or antivirus software is the only way to prevent any security breaches from happening.

The notion that Macs are virus-free is a widespread one. According to research, they contain malware. Therefore, for security reasons, installing antivirus or antimalware software on your computer and other devices is a smart practice.

Anti-malware programmes with extra functions are an option. Never be afraid to spend a little additional money when your security is at risk. Paid firewall versions come with extra security features. Consider selecting antivirus software that also includes a VPN.


In conclusion, stay vigilant about hackers. Through WiFi, is my computer vulnerable to hacking? Undoubtedly, yeah! Always utilize a safe and secure connection, whether you are browsing normally or on a page that asks for personal information. Use the above-mentioned precautions to protect your home WiFi or when connecting to a public network. Purchasing a reliable VPN and antivirus programme is preferable than compromising online security.
