Can a VPN Be Hacked? Yes! (How to Stay Safe)

In today’s interconnected world, where privacy and security are paramount concerns, many people turn to tools like Virtual Private Networks (VPNs) as a means of protecting their online activities.

While VPNs are widely regarded as effective tools for enhancing privacy and security, the question remains: can a VPN be hacked? The truth is that, similar to any service that depends on the internet, a VPN is susceptible to hacking.

In this blog, we will discuss how hackers and other threat actors can hack your VPN and what you need to look for in VPN to mitigate such risks:

How do VPNs get hacked?

While hacking a VPN service, especially a premium one, is challenging and nearly impossible, skilled and well-resourced hackers can still find ways to compromise it. Typically, hackers tend to set their sights on lucrative targets worth their time and effort. However, it is important to remember that no one is completely immune to the risk.

Here are some ways through which your VPN can be hacked:

1. Exploiting weaknesses in VPN software and protocols

No software is entirely immune to vulnerabilities. As technology advances and new features are introduced, potential vulnerabilities may emerge. In the case of VPNs, hackers focus on exploiting vulnerabilities that stem from how the VPN provider implements certain functionalities.

These vulnerabilities can arise in the code of the VPN app or the platform on which the VPN software operates. Hackers often target protocol implementation. VPNs that employ outdated protocols like PPTP and L2TP/IPSec are particularly susceptible to attacks due to inherent vulnerabilities in these protocols.

In addition, hackers may exploit new and untested protocols, misconfigurations in VPN settings, or flaws in the design of the VPN software’s code. Premium VPN services prioritize the use of secure protocols such as OpenVPN, WireGuard, and IKEv2 as they are less likely to have vulnerabilities.

2. Cracking VPN encryption

The strength of encryption depends on the chosen cipher and its implementation. Strong encryption involves using robust ciphers with longer key lengths, enhancing overall security. High-quality VPN providers prioritize secure ciphers like AES-256. Other reliable options include Blowfish and ChaCha20, each with different key lengths.

However, poorly implemented ciphers or those with shorter key lengths can be vulnerable to cryptographic attacks. Skilled hackers may use advanced computing resources to attempt breaking the encryption through methods like hashing and brute force attacks. While such attacks used to take years, modern technology has shortened the required time.

The good news is even with the emergence of quantum computing, properly implemented encryption like AES-256 would still require an incomprehensible amount of time – around trillions of years – to be successfully decrypted. 

3. Obtaining encryption keys

Encryption keys play a crucial role in the encryption and decryption process of ciphers. These keys, used in combination, ensure the security of the encryption. While skilled hackers possessing the correct encryption keys can easily break a VPN’s encryption and gain access to your online traffic, acquiring these keys is a complex undertaking. 

Unless hackers have the right connections and resources, like those available to organizations such as the NSA, obtaining VPN encryption keys is highly challenging. In recent times, most VPN providers have implemented measures to strengthen the encryption process. 

They now employ unique session keys that are periodically changed, achieved through Perfect Forward Secrecy (PFS). Even if a hacker manages to obtain the encryption keys, they will only be viable for a short session, limiting the amount of compromised data to a minimum.

4. Seizing VPN servers

Gaining control of a VPN server is the most direct method for hacking a VPN, as it grants access to all the connections passing through it. The security of a VPN server can be compromised through various means.

Hackers can exploit improperly configured VPN servers, taking advantage of vulnerabilities within the server’s settings. Additionally, they may target weak access control mechanisms or steal login credentials to gain unauthorized access to the server.

In certain cases, governmental entities or other interested parties may seize and breach VPN servers. This typically occurs when high-value targets are involved or within authoritarian countries where surveillance and control over online activities are prominent.

How a hacked VPN puts your security in jeopardy?

Individuals and businesses using a hacked VPN face a range of serious risks, including but not limited to:

• Unauthorized device access: If a cybercriminal sets their sights on you, a hacked VPN could pave the way for them to seize control of your devices by installing malicious software like ransomware or spyware.

• Leaked account credentials: A hacked VPN could allow prying eyes to snoop on your online communications. This could lead to the theft of your usernames, passwords, and other sensitive details.

• Stolen identity: Once cybercriminals have your personal information, they can use it to engage in identity theft – from applying for loans in your name to making fraudulent credit card transactions and even filing for government benefits illegally.

• Third-party surveillance: After a VPN hack, not only cybercriminals but also your Internet Service Provider (ISP), government agencies, and other entities can monitor your online activities as your connection is no longer secure.

Steps to take when your VPN is hacked

If your VPN gets hacked, here is what you need to do: 

1. Disconnect right away: The moment you find out your VPN has been hacked, disconnect immediately. Staying connected risks exposing your private data to prying eyes.

2. Uninstall the VPN app/software: It is a good idea to remove the hacked VPN app or software from your device. Some VPN services run background processes that could give hackers a backdoor to your device.

3. Change your login credentials: Presume all your login details have been compromised. Change these credentials and if the same password is used elsewhere, modify those as well. Using a trusted password manager like PureKeep can streamline this process.

4. Evaluate the severity and response: While not all VPN breaches result in a total compromise, the risks involved with VPN hacks are high due to the nature of the data they protect. Scrutinize how the VPN company responds to the breach and seek expert opinions to assess whether they have effectively mitigated the risks.

5. Switch to a More Secure VPN: The best course of action is to use a better VPN that is known for robust security measures and has not experienced any recent security lapses, such as PureVPN.

How to choose a hacker-resistant VPN

Here are some factors you should consider when looking for a hacker-resistant VPN:

1. Modern VPN protocols

The choice of VPN protocol plays a crucial role in determining how a VPN establishes its connections over the internet. The protocol governs the encryption methods employed for data protection.

A VPN service that prioritizes security uses robust VPN protocols that have undergone thorough testing and proven their effectiveness, such as WireGuard, OpenVPN, and IKEv2. By offering a selection of secure and well-established VPN protocols, the VPN service enhances its resistance to hacking attempts. 

2. High-grade encryption

Encryption serves as a fundamental aspect of VPN functionality. It plays a vital role in safeguarding your online traffic from potential compromises by hackers. When searching for a VPN, we recommend opting for those that employ the AES-256 encryption standard. 

When properly implemented, encryption using the AES cipher with a 256-bit key size is virtually impenetrable, even with the most advanced computing technologies. It is worth noting that adequately implemented AES-256 encryption has remained unbroken to date. This level of encryption is widely trusted and relied upon by banks and military institutions. 

3. No-Logs policy and jurisdiction

VPN providers that adhere to a strict no-logs policy refrain from monitoring or retaining any data regarding your online activities and connections. While this alone does not render a VPN completely impervious to hacking attempts, it significantly enhances your security and privacy, even in the event of a VPN compromise.

Additionally, a no-logs VPN safeguards your activities from prying third parties, including government entities seeking to monitor or access your online data. Equally important is considering the jurisdiction under which a VPN operates. A privacy-friendly jurisdiction ensures that government interference does not compromise your VPN connections and online activities.
