Can VPNs Be Hacked? We Did The Research

A VPN, or virtual private network, is one of the greatest ways to secure your internet connection and keep your data private. All of that protection, though, is for nought if a VPN is easily hacked.

What is the level of security provided by your VPN service? We made the decision to discover the truth. At the end of the day, it’s all about encryption and how much data your VPN leaks.

VPNs function by building a secure virtual tunnel across the Internet between two networks. If you utilise this virtual tunnel, no one, even your ISP, will be able to track your browsing activities.

A VPN protects the confidentiality and integrity of messages sent over the public Internet. This guarantees that your data is kept secure and unaltered.

Setting up a secure connection is straightforward. After you’ve established a connection with your ISP, set up a VPN connection with the software you’ve installed on your device. This software is also known as the VPN client.

The VPN server then gathers the requested web pages and transmits them to you through a secure tunnel, keeping your data safe and private.

But how can you know whether your VPN is secure? For the finest VPN companies, such as ExpressVPN, independent verification is feasible. Nonetheless, we’ll go through the most important VPN security features below.

How Do VPNs Encrypt Your Data?

VPNs use a specific protocol to encrypt and transmit your private data. Each protocol consists of a set of agreed-upon rules for data transmission and encryption.

Most VPN providers allow users to choose from a number of VPN protocols. Some of the most often used protocols include Point to Point Tunneling Protocol (PPTP), Layer Two Tunneling Protocol (L2TP), Internet Protocol Security (IPSec), and OpenVPN (SSL/TLS).

Anyone may look for and fix problems in OpenVPN because it is an open-source protocol. It’s widely considered as one of the safest VPN services accessible. If you’ve used a premium VPN service like ExpressVPN, you’ve undoubtedly utilised the OpenVPN protocol.

To fully grasp how a VPN protects your privacy, we need to dig deeper into the science of encryption.

VPNs use encryption to make your readable data (plaintext) completely unreadable if it is intercepted while travelling over the Internet (ciphertext). An algorithm or cypher governs the encryption and decryption operations inside VPN protocols.

Each protocol has its own set of strengths and weaknesses, depending on the cryptographic technique employed. Customers may choose from a range of cyphers with some VPN services. A symmetric, asymmetric, or hashing algorithm or cypher can be categorised into one of three types.

Symmetric encryption uses the same key to encrypt and decode data. Two keys are used in asymmetric encryption, one for encryption and the other for decryption. The table below provides a quick comparison of symmetric and asymmetric encryption.

Asymmetric cryptography is a solution to the limitations of symmetric encryption. By developing the Diffie-Hellman asymmetric algorithm, Whitfield Diffie and Martin Hellman were among the first to address these flaws.

HTTPS, SSH, IPsec, and OpenVPN are all VPN protocols that employ the Diffie-Hellman cryptographic algorithm. The method allows two individuals who have never met before to negotiate a private key even via an unsecure public channel like the Internet.

Hashing, on the other hand, is an irreversible, one-way encryption technique. It’s used to keep data transferred over the internet, such as passwords, safe.

Most VPN protocols employ hashing algorithms to verify the authenticity of communications sent over the VPN. Some examples are MD5, SHA-1, and SHA-2. On the other hand, MD5 and SHA-1 are no longer considered secure.

Is It Possible To Hack A VPN?

VPNs are one of the most effective ways to protect your online privacy since they encrypt your data and use private DNS servers. It’s crucial to remember, though, that everything may be hacked. This is especially true if you’re a high-value target with a significant amount of time, money, and resources on the line.

The good news is that the vast majority of consumers are not classified as “high-value,” thus they will not be targeted.

There are two techniques to hijack a VPN connection. A hacker might either exploit known flaws or use unethical methods to break the encryption.

Encryption, on the other hand, is computationally challenging and time-consuming to break. Breaking the encryption with powerful computers can take years.

Rather, the bulk of assaults are aimed at stealing the keys. For example, spy agencies prefer this method to the laborious task of decrypting data.

Because the math that underpins encryption is computationally complex, stealing a key is far easier than stealing a key. Their success is due to a combination of technical trickery, processing power, cheating, judicial orders, and behind-the-scenes influence.

VPNs can be hacked, but it’s a difficult task. Furthermore, individuals who do not utilise a VPN have a far higher chance of being hacked than those who do.

Security experts Alex Halderman and Nadia Heninger provided convincing evidence that the NSA did develop the ability to decode a large volume of HTTPS, SSH, and VPN traffic. This sort of assault is known as a logjam.

Their success was achieved by taking advantage of a vulnerability in a commonly used Diffie-Hellman algorithm implementation. The underlying source of this issue is the prime number used to do the encryption.

The researchers estimated that it would take a year and a few hundred million dollars to create a powerful computer capable of breaking a single 1024-bit Diffie-Hellman prime.

Unfortunately, the researchers observed that just a few prime numbers are commonly used with 1024-bit encryption. Apps like VPNs are included, making it even more difficult to breach.

VPNs’ encryption does not have to be compromised in order for your connection to be vulnerable. One of the simplest ways for your data to be exposed to a third party is through VPN breaches.

An IP leak is the most typical event. While transmitting data, your browser may still reveal your real IP address. They may not have access to your traffic data in this case, but they can monitor your location.

Your traffic may periodically leak when using a VPN, allowing your ISP to see exactly what you’re seeing. They’ll be able to see who has watched it as well. Keep an eye out for DNS leaks as well. See this page for additional information on the differences between DNS leaks and IP breaches. 

Knowing how to detect and remedy breaches is essential if your main concern is privacy. Although most VPN companies claim that their software includes DNS leak prevention, we discovered that this isn’t always the case. These three main VPN providers, according to our analysis, were leaking data.

Should You Still Use A VPN?

Your home network is usually safe if you use a strong Wi-Fi password. You may also rely on the most recent software upgrades for additional router security. Using a home VPN, on the other hand, provides an extra layer of security against hackers and snoops that your local internet provider does not give.

A home VPN masks your IP address while you’re online, preventing your ISP from monitoring your activities. When you use a VPN on your home network, you may surf anonymously, which can lead to lower airline fares, unrestricted streaming, and no digital limitations.

Even if your home network is more secure, you might wish to set up a VPN for personal use on your Windows or Mac computer.

It’s the extra layer of anonymity that allows you to surf the web anyway you choose. There’s no need to worry about your ISP selling your data to the highest bidder or whether you’re being duped by price gouging. Using a VPN for your home network provides you peace of mind and the freedom to roam about.

The Benefits Of Having A VPN?

There are several advantages to using a VPN. One of the most important capabilities of organisations is their capacity to effectively secure their networks. Without your knowledge, a software or website can track your online actions. They can then analyse the data and try to target you with adverts based on it. 

If you don’t use a VPN, you may see a lot of pop-up advertising, which may be irritating and interrupt your browsing experience. When you use a VPN, people, software, and web browsers are unable to access your connection. This guarantees that the information you provide and receive is safe and secure.

The ability to hide your personal information is one of the most essential advantages of a VPN. Hackers can use a variety of ways to intercept sensitive information you input on websites.

They can use that information to impersonate you and get access to your bank accounts, credit card numbers, and other sensitive data.

A VPN provides high-level security, such as 256-bit encryption. Anyone listening in on your online discussions will see a mess of useless text and characters.

Data throttling occurs when you’ve used up all of your allowed data and your internet service provider (ISP) decides to slow down your connection.

You’ll quickly learn that one of the benefits of using a VPN is the ability to avoid data limitations, especially because neither your ISP nor your ISP can see how much data you use. Employees who must use data plans on their mobile devices to access the internet while on the road may find this particularly useful.

The practise of intentionally slowing down your internet speed by your ISP or someone else with control over how your Wi-Fi network functions is known as bandwidth throttling. This may occur when you visit certain websites or engage in certain internet behaviours.

If you use a digital VPN service, the mobile traffic that originates from your device may be protected. Because of the encryption, others will not be able to see the websites you are visiting.

Because bandwidth throttling might be triggered by the websites you visit or the activities you engage in, your ISP won’t be able to slow it down if they can’t see the data travelling to and from your device. They may, however, limit your connection at certain times of the day to make room for other users.

In most situations, employees and anybody else who uses your internet connection will not be throttled based on their internet usage, but using a VPN allows businesses to disguise their data flows and completely eliminate the danger.

Using a VPN, you may get an alternative Internet Protocol (IP) address. When a device browses the internet, streams content, or performs other online activities, its IP address reveals its location.

Users from certain countries are denied access to parts or all of the material on various websites and services. This is common with streaming services that cater to certain geographic locations.

Depending on where you are, several corporate websites restrict how you may utilise their public work services, such as getting estimates or seeing more specific information about their services.

Using a VPN, you may make it look as if you’re accessing the internet from a place that’s acceptable to the service you’re trying to access.

While a private network might assist your business in getting off the ground, the cost of expanding it can be prohibitive.

If you use a VPN server, you may offer access to several employees and remote workers at the same time. You may also use the cloud to run important programmes and allow them access over the VPN’s secure tunnel.

Email to full-fledged programmes that would normally be installed on a desktop computer are examples of this. When employees connect to the VPN, they have access to a new computer where you may run the software they need.

The VPN and, as a result, the programme may be used by any employee who has a login. Adding more employees is as simple as giving each new team member more bandwidth and login credentials.

If you pick a VPN setup that incorporates cloud computing architecture, you might save a lot of money on support services.

Internal IT personnel, for example, are typically responsible for the operation and upkeep of the in-house server in an on-site setup. It might take hours to check how effectively the server is running, if all employees are getting optimal throughput, and whether it is under attack from hackers or viruses.

Furthermore, after an issue has been identified, further time and attention must be spent addressing it as well as the consequences it may have had within your company.

With a VPN, however, the service provider is responsible for all maintenance, performance monitoring, and security measures. Because they have a large number of paying clients, their IT expenditures are covered, resulting in a cheap cost per client.

These savings are passed on to you as cheaper rates than if you hired a specialised staff to handle your infrastructure. Without a doubt, this is one of the most important VPN advantages for organisations.

Examine the provider’s services as well as the equipment they employ to make sure this is the case. More modern components and security measures usually result in a better experience for you, the consumer.

Final Thoughts

So, is a VPN really worth it? The benefits of using a VPN vary depending on how crucial it is to your digital life. Some gamers, for example, use a VPN to disguise their location or mask their IP address when playing. The primary benefits of using a VPN are increased online security and a better user experience.

Online privacy is a major issue that affects a wide range of aspects of your life. There are numerous reasons to acquire a VPN and safeguard your data and surfing online, from advertising trying to unfairly target you online to hackers trying to swoop in on an unprotected Wi-Fi network and steal your information.

Using a VPN has different benefits depending on how essential it is to your online life. Some gamers, for example, use a VPN to mask their location or camouflage their IP address when playing. The two major benefits of using a VPN are increased online security and a better user experience.

Online privacy is a major issue with implications in many aspects of your life. There are several reasons to acquire a VPN and safeguard your data and internet browsing, ranging from advertising seeking to unfairly target you online to hackers attempting to swoop in on an unprotected Wi-Fi network and steal your information.

Despite the fact that VPNs are meant to protect your data from third-party snoopers, many free VPNs sell your data to others.

Third-party snoopers frequently utilise this information to better target advertisements to specific individuals. While a VPN is supposed to protect your data, many simply hand it over to the highest-paying company.

Finally, some free VPNs have data caps and only cover one or two devices. They don’t always have the fastest connections, so 4K movies and large files take longer to download than normal.

Many free services will try to persuade you to upgrade to a paid version in order to get the info you want.

Data is one of the most valuable commodities on the planet. Individuals only have so much control over their internet privacy because their data is sold on a variety of sites. By using a VPN, you may recover some control over the information you share with your ISP and other third parties.

Finally, if you’re asking whether or not a VPN is worthwhile, the answer is a resounding yes.
