Can VPNs Be Hacked? We Did The Research, Here’s the …
A VPN or virtual private network is one of the best ways to secure your internet connection and keep your data private. However, all of that protection amounts to nothing if a VPN can be easily hacked. How secure is your VPN service? We decided to find out. In the end, it comes down to encryption and how much your VPN leaks.
VPNs work by creating a secure virtual tunnel through the Internet to another network or device. Using this virtual tunnel makes it difficult for anyone – including your ISP – to see your browsing activities.
A VPN protects the confidentiality and integrity of messages as they travel over the public Internet. This means your data remains secret and unaltered.
It’s easy to establish a secure connection. After you connect to your ISP, initiate a VPN connection through the software you’ve installed on your device. This software is also called the VPN client. From there, the VPN server fetches the requested web pages and returns them to you through a secure tunnel, thus keeping your data secure and private.
But how do you know if your VPN is truly secure? The top VPN services like ExpressVPN can be independently verified. Even so, we’ll walk you through the important aspects of VPN security below.

How Does VPN Encryption Work?
VPNs use a specific protocol to transmit and encrypt your private data. Each protocol is an agreed upon set of rules for data transmission and encryption. Most VPN providers give users the option to choose from several VPN protocols. Some of the most used protocols include: Point to Point Tunnelling Protocol (PPTP), Layer Two Tunnelling Protocol (L2TP), Internet Protocol Security (IPSec) and OpenVPN (SSL/TLS).
OpenVPN is an open-source protocol, which means anyone can look for and patch vulnerabiliies. It’s considered one of the best options for VPN security. If you’ve used a premium VPN service like ExpressVPN, then you’ve likely used OpenVPN protocol.
In order to fully understand how a VPN protects your privacy, we need to dig a little deeper into the science of encryption. VPNs use encryption to make your readable data (plaintext) completely unreadable (ciphertext) in case it’s intercepted as it travels through the Internet. An algorithm or cipher dictates how the encryption and decryption process takes place within the VPN protocols.
Each protocol has its strengths and weaknesses based on the cryptographic algorithm implemented within it. Some VPN providers give users the option to choose from different ciphers. The algorithm or cipher can be based on any of these three classifications: symmetric, asymmetric, and hashing algorithm.
Symmetric encryption uses one key to lock (encrypt) and unlock (decrypt) data. Asymmetric encryption uses two keys, one for encrypting and the other for decrypting data. The table below is a summary comparison between symmetric and asymmetric encryption.
Asymmetric cryptography is the solution to the limitations inherent in symmetric cryptography. Whitfield Diffie and Martin Hellman were among the first group that set out to address these shortfalls by developing an asymmetric algorithm called Diffie-Hellman.
Diffie-Hellman is a popular cryptographic algorithm that is fundamental to many VPN protocols including HTTPS, SSH, IPsec, and OpenVPN. The algorithm lets two parties that have never met before negotiate a secret key even when communicating over an unsecured public channel such as the Internet.
Hashing, in comparison, is a one-way, irreversible type of encryption. It’s used to protect the integrity of transmitted data, such as passwords. Most VPN protocols use hashing algorithms to verify the authenticity of messages sent via the VPN. Examples include MD5, SHA-1, and SHA-2. However, both MD5 and SHA-1 are no longer considered secure.
Can Someone Actually Hack into a VPN? By encrypting your data and using private DNS servers, VPNs remain one of the most effective means of maintaining online privacy. Nevertheless, it’s important to note that anything can be hacked. This is especially true if you are a high-value target and your adversary has enough time, funds, and resources. The good news is that most users do not fall into the “high-value” category and are therefore unlikely to be singled out.
Hacking into a VPN connection involves one of two tactics. A hacker can either break the encryption through known vulnerabilities or steal the key through unethical means. Cryptographic attacks are used by hackers and cryptoanalysts to recover plain text from their encrypted versions without the key. However, breaking encryption is computationally demanding and time-consuming. It can take strong computers years to actually break the encryption.
Instead, most attacks tend to involve stealing the keys. Spy agencies, for example, generally prefer this method over the complex task of breaking encryption. Given that the math behind encryption is computationally complex, stealing a key is a far easier task. Their success comes from a combination of technical trickery, computing power, cheating, court orders, and behind-the-scenes can be hacked, but it’s hard to do so. Furthermore, the chances of being hacked without a VPN are significantly greater than being hacked with one. Existing VPN Vulnerabilities and ExploitationsEdward Snowden and other security researchers previously revealed that the US spy agency, the NSA, did crack the encryption protecting a large amount of internet traffic, including VPNs. The Snowden documents show that the NSA’s VPN decryption infrastructure involves intercepting encrypted traffic and passing some data to powerful computers. The computers would then return the key.
Security researchers Alex Halderman and Nadia Heninger also presented convincing research suggesting that the NSA did develop the capability to decrypt a large number of HTTPS, SSH, and VPN traffic. This attack is known as Logjam.
Their success was based on the exploitation of a weakness in a common implementation of the Diffie-Hellman algorithm. The root cause of this weakness stems from the prime number used to implement the encryption. The researchers estimated it would take about a year and a few 100M dollars to build a powerful computer that would be able to crack a single 1024 bit Diffie-Hellman prime. This is a cost the NSA can afford, but it wouldn’t be enough to decrypt the multiple encryption keys that secure millions of websites and VPNs.
Unfortunately, the researchers found that only a few prime numbers are commonly used for 1024-bit encryption. This includes applications such as VPNs, and therefore, makes it even easier to break. According to Bruce Schneier, “the math is good, but math has no agency. Code has agency, and the code has been subverted”.
VPNs and IP LeaksOf course, VPNs don’t need their encryption to be compromised to make your connection vulnerable. One of the simplest ways your data can be revealed to an outside party is via VPN leaks. Most frequently, this involves an IP leak. In the process of transmitting your data, your browser may still leak your real IP address. They may not have access to your traffic data in this case, but they can trace your location.
Sometimes, however, your traffic can leak while using a VPN, which would let your ISP know exactly what you’re viewing. Not only that, they’ll know who viewed it. You should also watch out for DNS leaks. For more on understanding the difference between DNS leaks and IP leaks, you can refer to our guide. Learning to test and fix a leak is a useful skill if privacy is your biggest concern. We’ve also written a guide on how to test and fix a VPN leak.
Though most VPN companies claim they have DNS leak protection built into their software, we discovered that this isn’t exactly true for a number of VPN providers. Based on our research, these three top VPN services were leaking data.
Should You Still Use a VPN? For service providers, the research team recommends the use of 2048-bit or more Diffie-Hellman keys and also published a guide to its deployment for TLS. The Internet Engineering Task Force (IETF) also recommends using the latest revisions of protocols which require longer prime numbers.
Spies may be able to crack primes commonly used in Diffie-Hellman keys up to 1024 bits (about 309 digits) in length. Primes in 2048-bit keys are more difficult, meaning the spies won’t be able to decrypt data secured using these keys for a very long ’s true that the spy agencies have exploits to target VPNs and other encryption protocols. However, you’re still better protected than if you communicate in plain text. While your computer can be compromised, it would cost them time and money. The less obvious you are, the safer you are. According to Edward Snowden, “Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. ” As much as possible, avoid VPNs that are primarily based on MD5 or SHA-1 hashing algorithms and PPTP or L2TP/IPSec protocols. Go for those that support current versions of OpenVPN (considered extremely secure) and SHA-2. If unsure which algorithm your VPN uses, refer to the VPN’s website or contact are your friend. You can trust the math behind encryption. Maximize their use, and do your best to ensure your endpoint is also protected. That’s how you can remain secure even in the face of the crackdown on encrypted connections. But, how can you know which VPNs are truly secure? Which VPNs Can’t Be Hacked? Even if all VPNs can be hacked with enough time and money, there are several providers who have leak protection that actually works. Here is the top VPN that has been proven to have the best security.
1. ExpressVPN

Does Cracked VPN Work? Are They Safe to Use? – Anonymster
With online threats, surveillance, censorship and geo-restrictions being stronger and more troublesome than ever, millions of people around the world have started using VPN technology to protect themselves on a regular basis. However, there are always those who would rather use a VPN without having to pay for it. With nearly every VPN guide, text, and article out there explaining all the reasons why free VPNs are a bad idea, many tend to turn to the possibility of a cracked VPN software.
So, today, we would like to discuss this idea also and see whether a VPN crack like ExressVPN crack, CyberGhost VPN crack, NordVPN crack, IPVanish crack or similar is a good idea. We will even consider whether cracked VPN works and, most importantly, the possible dangers that come with it.
Do Cracked VPNs Work?
The short answer is that they might work but there are several downsides and dangers to it.
Whether a VPN crack works or not often depends on a number of factors. However, one thing that you should remember is that, even if you somehow get them to work, they will never bee as good as regular, premium VPN services.
You will often bump into problems that premium members do not have to deal with. Furthermore, you won’t have customer support to help you resolve any issue you may run across.
Cracked VPNs may be free, but they are not safe.
Always remember that using something free means that you are still paying for it, only in a different way.
You may keep your money, but you will expose your data, privacy, security, and possibly more.
VPN Crack – What Problems Are There When Using It?
As mentioned, using cracked VPNs can be quite problematic, as they often end up simply not working. Some of the major issues you most likely will deal with include:
1) VPN Doesn’t Work After Update
As you know, VPNs often change some aspects of their service. Whether that includes listing new server locations, replacing existing ones, adding new features, or even simply adding patches that fix some issue with the app — updates are usually quite common.
However, if you crack a VPN, and it receives an update, you might end up losing access to it, and it will simply stop working for you.
2) It Might Not Be Secure Anymore
As mentioned, updates are often made in order to implement new security patches. No technology is 100% perfect, and new vulnerabilities, bugs, and other flaws are being discovered all the time, which is why VPNs constantly keep issuing new updates.
Now, if you use a cracked VPN, and the VPN company issues a patch, you might still manage to run your VPN.
However, if this happens, chances are that you won’t receive the security patch that you now require in order to stay safe while using a VPN. Even if the flaw within the app was kept hidden, it is likely to be reported once the patch is out, which makes you vulnerable, since you do not have it.
3) You Might Not Be Connected To the Right Server
If you crack a VPN and it is still able to connect, that means that it should be working.
However, there is still a possibility that the VPN crack brought some internal changes, including the server address that you are now using. That means that your online activities — all of your online activities — might be stored somewhere else, and not on the VPN’s own servers.
That means that there is a fair chance that those who cracked the VPN may have changed the server to which the data goes.
They might even be collecting it themselves, which means that they will see everything that you are doing and that they might collect sensitive data, such as credit card numbers, login info, and more.
This is a very serious danger that cannot be overlooked!!
4) Hackers May Trick You
As mentioned, it would not be unheard of for hackers to crack a VPN and then leave it for people to find it and start using it. Meanwhile, all of their sensitive data is being stored on a hacker-owned server, and they can then do with it whatever they want.
However, there is also a risk that the VPN crack might be malware in disguise.
In other words, the crack could be real, but it might not arrive at your device alone. Hackers are known for using such disguises for infecting computers, as many modern anti-malware and anti-virus systems can recognize and prevent malicious threats.
If you download a VPN crack that is hiding malware inside, there is no telling what kinds of problems you may experience later on.
It might be ransomware that would encrypt all of your files and ask for money in order to release them. It might be a cryptojacking malware, that will use your computing power and electricity to mine cryptocurrencies. It might be spyware, or something completely different, but just as damaging. Hackers could steal your data, money, identity, and more.
VPN Crack – How to Protect Yourself?
The best and easiest way to ensure your safety is to simply pay for a premium VPN. If you look at services such as CyberGhost, NordVPN, Surfshark, and alike — you will see that even these top services only cost a bit over $3 per month, or even less than that if you go for a yearly subscription. Alternatively, you can check our full list of the best VPNs and you will see that some of them are very economical.
This is not that expensive. In fact, many would agree that it is quite cheap. In consideration of that, it is difficult to understand what is the benefit of using ExpressVPN crack, NordVPN crack, CyberGhost crack, IPVanish VPN crack, or the like.
The alternative is to risk your privacy, money, identity, security, and more, just to save $3 per month. Saving $3 per month could easily become the most expensive move you have ever made if you go for cracked VPN and allow someone to take away everything from you.
In the end, you simply have to ask yourself: Is your personal data not worth a few dollars per month?

Many VPN users wonder whether they should use a cracked VPN: does a cracked VPN work to protect you? And is it safe to use? This article will help answer these questions so you can make an informed is a Cracked VPN? A cracked VPN is a pirated version of premium VPN software that you can download from the internet. It comes with an activation code to appear legitimate but is in fact fake and unlawful. No reputed company will give out free activation codes for their premium software. And as the saying goes, there ain’t no such thing as a free lunch! You might come across websites or individuals on forums and social media offering links to free downloads of premium VPN software. For instance, an ExpressVPN crack file might be said to work just as well as the full-fledged premium ExpressVPN software, without you needing to pay the subscription fee. But these kinds of offers and assurances are just a scam. Even though you may get the cracked VPN for free, you’ll be paying for it in other ways, namely by sacrificing your are also unscrupulous online vendors selling premium VPN subscriptions at slashed prices. These might seem like attractive offers, but they are in fact just stolen VPN accounts from premium users with weak passwords. This means your information could be viewed by the people selling such VPN subscriptions. So, don’t be fooled and always buy subscriptions directly from the that you have an idea about how cracked VPNs work, let’s consider whether they’re even effective or Cracked VPNs Work? Yes, technically a cracked VPN will work, but there are many risks involved. It could be harmful to your device and your privacy, as explained in detail below. Moreover, you should remember that a cracked VPN is pirated software that is illegal to use. You could get in trouble with the VPN company and the law if you’re detected using such while your cracked VPN might work to help you browse anonymously or access geo-restricted content, it’s never worth the security risks involved. In fact, in a lot of cases using a cracked VPN is worse than using no VPN at all. Let’s check out some of the potential it Safe to Use a Cracked VPN? Using a cracked VPN can be very unsafe. These pirated crack files can cause serious damage to your device and your online privacy. Even if they seem to work fine, you may be exposing yourself and your device to risks that can be very tricky to deal with. Here are some of the dangers involved:1. Viruses and ransomwareWhen you download a pirated copy of a VPN, it’s usually from a random unknown webpage, a link someone has given you, or an anonymous mirror or server. All of these make you susceptible to downloading dangerous viruses and malware in disguise. These can infect your device and be difficult to get rid of. Even the best antivirus software might not detect all types of viruses and ’s more, you could unknowingly download ransomware onto your system. Ransomware will lock all your files and ask for money to release them. Is it really worth risking your security and exposing yourself to such trouble for the sake of a free VPN that may or may not work? We certainly don’t think so. 2. AdwareSuppose you get lucky and don’t download some pesky virus or ransomware. You could still run into other kinds of malware. For instance, adware can be just as much of a nuisance, even if it is generally less dangerous. This kind of program floods your computer or mobile device with ads. You’ll see annoying pop-ups everywhere with no easy way to get rid of them. This can slow down your system and also lead you to malicious websites if you accidentally click on the ads. 3. No updatesVPNs constantly release new updates for their software to protect against new bugs, threats, and vulnerabilities. Cracked software will not have this advantage, which can lead it to malfunction and compromise your security. Even if your pirated software does receive the latest updates, it might stop working because it’s not genuine software. This makes it pointless to try and use a pirated VPN. 4. Privacy risksWhen you download and use a cracked VPN, you risk your online privacy. This completely defeats the purpose of using the software in the first place. Even if the VPN works, it may be connecting to unknown servers set up by hackers or whoever pirated the software. This means that all your online activities and data may be available for third, complete strangers could be seeing everything you’re doing online and might also collect your personal data. This can include sensitive information like login credentials, credit card numbers, and so on. Obviously, this is a major privacy concern that cannot be ignored. It could make you the victim of fraud and other kinds of harassment. 5. No access to customer supportWhen you don’t use genuine VPN software, you can’t benefit from the technical assistance and guarantees that it offers. Most of the best VPN companies have great customer support that can help you deal with any issues you might face when using the software. This is invaluable when you’re not satisfied with the service or something goes wrong. But when you’re using pirated VPNs, you’re on your own to sort out issues and could end up jeopardizing your security, doing more harm than good to your to Avoid Cracked VPNsConsidering all the disadvantages of cracked VPNs explained above, we strongly recommend that you steer clear of them. It’s better to use no VPN at all than to risk your security and online privacy with a cracked might wonder how you can make sure you don’t accidentally use a cracked VPN. Luckily, it’s quite easy to make sure this doesn’t happen. Here are some tips to avoid falling for a cracked VPN bscribe via the official websiteEnsure you always subscribe via the official website of a VPN provider. Here are some pointers to help you determine whether you’re on the right page or not:An official VPN provider website will nearly always have a URL carrying their brand or company name. It’ll also often start with. The “s” indicates that it’s a secure site. However, there are fraudulent websites out there that use HTTPS as well, so also make sure to pay attention to other aspects. A genuine VPN site should look clean and well-organized. It shouldn’t have any irrelevant pop-ups or strange ads. The “About us” page can tell you more about the owner of the website and the VPN, if you’re in links from trusted review platforms, like VPNOverview, will instantly send you to the right page on the right website. If you’re in doubt, you can always use the buttons on our subscriptions instead of one-time paymentsBe wary when VPNs appear to offer a one-time payment instead of a subscription-based system. Most trustworthy VPNs have monthly fees. If you come across a provider that will give you an account for life, you should be suspicious, especially if you read in other places, like on their official website that this same provider uses a different search deals and pricesNever believe a deal that sounds too good to be true, especially when you read about them on fora.
