Enable a VPN to encrypt your online activity

If your computer server has recently crashed or experienced unusual traffic spikes, there’s a possibility it could be related to an IP spoofing attack. IP spoofing occurs when a malicious actor falsifies the source IP address in data packets to impersonate another computer, server, or trusted system.

However, enlisting the help of one of the best VPNs can help protect you by encrypting your internet traffic and replacing your visible IP address with that of the VPN server. This enhances privacy and protects your data while it’s in transit.


Here’s what you need to know about IP spoofing — including how it works, why it’s used, and how a VPN can best protect you.

What is IP spoofing?

Internet Protocol (IP) spoofing occurs when a fraudster uses a false source IP address to impersonate another computer or system. It's typically used for malicious purposes to steal your data or crash servers.

According to Kaspersky, this works when data is transmitted over the internet is first broken into multiple packets, and those packets are sent independently and reassembled at the end. Each packet has an IP (Internet Protocol) header that contains information about the packet, including the source IP address and the destination IP address.

In very simple terms, it’s like sending a letter with a fake return address. A hacker sends internet data packets with a false source IP address to pretend to be someone else.

A hacker then uses these tools to modify the source address in the packet header to make the receiving computer system think it's from a trusted source, such as another computer on a legitimate network, and accept it. This occurs at the network level, so there are no external signs of tampering.

It’s different to IP masking, which replaces the user's real IP address with a different, often virtual, IP address.

How a VPN can help protect against IP spoofing

A VPN can protect you against IP spoofing by encrypting your traffic and masking your real IP address with the server's IP, making it much harder for attackers to see your actual location and tamper with data in transit.

One thing to note is that it's not a complete solution for every type of spoofing or network-level attack. For instance, A VPN creates a secureconnection between your device and the VPN server, but it does not verify the authenticity of emails, websites, or devices beyond that point — meaning it does not stop you from visiting a fake, malicious website.

If you're in search of a VPN that will help protect your privacy and is a highly recommended service, we recommend ExpressVPN.

What is a VPN?

A Virtual Private Network (VPN) is software that protects and anonymises everything you do online. VPNs can conceal your online activities by routing traffic through an encrypted tunnel that connects to secure servers worldwide.

The most reliable cheap VPNs or even free VPNs employ the same encryption standard as governments in the United Kingdom and the United States, ensuring that even your Internet Service Provider (ISP) connected to Wi-Fi cannot record the websites you visit, the duration of your sessions on each site, or your current location. This protection extends to advertisers, trackers, and hackers, preventing them from monitoring your online behaviour.

Furthermore, personal information entered into online forms and sensitive data transmitted to and from your device will be safeguarded from hackers using strong encryption provided by a VPN.
