What are the risks of using a VPN?

Using a VPN entails some risks. These include potential data leaks due to unreliable VPN providers, exposure to malicious websites if the VPN lacks proper security features, and trusting VPNs based in countries with strict data retention laws. Moreover, VPNs may not completely protect against advanced surveillance techniques, and users might engage in illegal activities assuming they’re anonymous.

What are the risks of using a VPN

Risks of Using a VPN

The use of VPN services has steadily increased over the years due to their claim of providing online anonymity and security. However, they are not without their share of risks. One of the most alarming issues surrounding VPNs is the potential for privacy and data leaks.

The Reality of Complete Anonymity

While VPNs promise to mask your IP address, which can hide your geographic location and internet activities, they can’t guarantee 100% anonymity. Some VPNs can accidentally expose your real IP address during your online sessions, potentially revealing your actual location or internet provider. This situation is called an IP leak.

Data Logging Practices

A less obvious but equally important risk involves data logging practices. Although most VPN providers claim they don’t keep logs of users’ activities, some still do for various reasons. They might collect and store data about your browsing history, connection times, IP addresses, and even device information. For example, in 2018, a popular VPN service, PureVPN, admitted to logging user data, contradicting their privacy policy.

Encryption Quality and Data Leaks

The level of encryption provided by a VPN also plays a critical role in data protection. Not all VPNs offer high-grade encryption, which can result in data leaks. A VPN might use a 256-bit encryption standard, which is highly secure, while another could use a 128-bit standard, offering less protection. The AES-256 encryption is the most recommended due to its high level of security, but it also requires more processing power, potentially slowing down your internet speed.

DNS Leaks

When you visit a website, your device typically sends a request to a DNS server to translate the website name to an IP address. Some VPNs can expose these DNS requests outside the VPN tunnel, an issue known as a DNS leak. DNS leaks can give away your browsing history to your Internet Service Provider or third-party DNS servers, even if you use a VPN.

Malware Risks Associated with VPNs

Alongside privacy concerns, malware presents another substantial risk to VPN users. Contrary to the common belief that VPNs inherently protect from all cyber threats, their use may expose devices to certain malware risks.


VPNs as Trojan Horses

While VPNs can protect your data from external attacks, some VPN applications themselves might contain malicious software. This risk is particularly significant with free VPN services. An analysis in 2020 by the cybersecurity company Metric Labs found that of 150 free VPN apps on the Google Play Store, over 25% had potential malware or viruses, and 85% featured excessive permissions or functions that could put users’ privacy at risk.

The Risks of Downloading VPNs

When downloading a VPN application, especially from a less reputable source, there’s a risk of getting an application infected with malware. For instance, certain types of malware, such as spyware, can track your keystrokes, capture screenshots, and send this information to cybercriminals. Cybersecurity researchers have discovered instances where malware was embedded within free VPN software, causing harmful consequences for users who unwittingly downloaded and installed the compromised applications.

Inadequate Malware Protection

While some VPNs claim to offer extra security features like built-in antivirus or malware protection, they often fall short of a dedicated antivirus software. A VPN’s primary purpose is to encrypt internet traffic and hide the user’s IP address, not to protect against malware or viruses. So even when connected to a VPN, without a reliable antivirus program, a user might still be vulnerable to malware attacks.

The Role of Reliable Antivirus Software

Investing in reliable antivirus software is crucial, even when using a VPN. It’s recommended to use antivirus software from reputable providers like Norton, McAfee, or Bitdefender. These programs offer robust protection against a wide range of malware, including ransomware, spyware, and phishing attacks, and often include features like real-time protection and frequent malware definition updates.

VPN Vulnerabilities and Hacking Risks

As with any internet-connected technology, VPNs have vulnerabilities that, if exploited, can make users prone to hacking.

Weak and Outdated Encryption Algorithms

The encryption algorithm a VPN employs is vital to maintaining user data privacy. However, some VPNs use outdated or weak encryption algorithms that hackers can more easily exploit. For instance, the PPTP (Point-to-Point Tunneling Protocol), once a popular encryption protocol, is now considered insecure and susceptible to various attacks, such as the MS-CHAP v2 crack tool.

Unpatched Software Vulnerabilities

Another issue relates to the VPN software itself. Like any other software, VPNs can contain vulnerabilities. If the VPN provider does not regularly update and patch their software, hackers can exploit these vulnerabilities. For example, in 2020, a severe vulnerability was found in several commercial VPN products from Pulse Secure, Fortinet, and Palo Alto Networks, potentially allowing hackers to steal sensitive user data.

Risk of Server Hacking

While less common, there are cases where hackers have compromised VPN servers. In 2019, NordVPN, a well-known VPN provider, disclosed that a hacker gained access to one of its servers in Finland due to an insecure remote management system used by the data center provider. Although NordVPN assured users that no personal data was compromised, the event demonstrated that even reputable VPNs aren’t immune to hacking.

The Importance of Security Measures

To protect themselves from these potential vulnerabilities, users should select a VPN that uses up-to-date, strong encryption methods, such as OpenVPN or IKEv2/IPSec protocols, coupled with the AES-256 encryption standard. Additionally, users should regularly update their VPN software and use additional security measures, such as two-factor authentication and robust antivirus software.

Risks Related to VPN Provider Policies

One overlooked aspect of VPN use is the dependency on the VPN provider’s policies. The VPN provider’s decisions around logging, data sharing, and server location can significantly impact a user’s online privacy and security.

Data Logging Policies

As discussed earlier, the data logging policy of a VPN provider is of paramount importance. Not all VPN providers uphold a strict no-logs policy. Some may keep certain logs, either for a short duration (like session logs) or longer periods. For instance, HideMyAss, a VPN provider, handed over user log data to law enforcement in a 2011 cyberstalking case, raising serious questions about user privacy.

Jurisdiction and Data Sharing

The VPN provider’s jurisdiction can determine the laws they must follow, including those related to data retention and sharing. For example, a VPN provider based in a Fourteen Eyes country may be legally obliged to share user data with government agencies. Therefore, users should consider the implications of the VPN provider’s location and the local laws it falls under.

Server Ownership and Management

Some VPN providers use third-party servers or virtual servers, which can affect data security. The 2019 NordVPN server breach occurred because a third party inadequately managed the server. It’s often better to choose a VPN provider that owns and manages its server network to ensure proper security protocols.

Changes in Policies

VPN providers can change their policies. A VPN provider could decide to start logging user data or sharing data with third parties. Therefore, it’s crucial for users to regularly review the terms of service and privacy policies of their chosen VPN provider.

VPN Impact on Internet Speed and Performance

While using a VPN adds an extra layer of security and privacy to internet browsing, it can impact your internet speed and overall performance.

Internet Speed

Using a VPN usually slows down your internet speed to some degree. This is because your data has to travel farther to reach the VPN server, and it takes time to encrypt and decrypt the data. According to a 2022 report by AV-TEST, an independent IT security institute, the average internet speed when using a VPN can decrease by up to 25%, depending on the VPN provider and server location.

Server Distance and Load

The distance between the user and the VPN server can also impact speed. The farther the VPN server is, the slower the speed may be. Additionally, if a particular VPN server has many users connected at the same time, it can lead to a slower connection due to increased load.

Device Performance

Using a VPN can also affect the device’s performance. Encrypting and decrypting data requires processing power, which can slow down older devices or devices with limited processing capability. For instance, a smartphone from 2019 may experience a more significant performance drop when using a VPN compared to a latest-generation smartphone.

Choosing the Right VPN for Speed

If speed is a primary concern, it is worth doing some research before choosing a VPN provider. Some VPNs, such as ExpressVPN and NordVPN, are known for providing faster speeds due to their large server networks and advanced technology.

 Legal Considerations and Restrictions of VPN Use

The use of VPNs isn’t always straightforward from a legal perspective. While it’s generally legal to use a VPN in most countries, some considerations and restrictions can apply.

Illegal Activities

VPNs are legal tools, but they can be misused for illegal activities. Engaging in activities such as hacking, spreading malware, cyberstalking, or illegal file-sharing while using a VPN is still against the law. In 2020, an individual from Nevada was sentenced to 12 years in prison for using a VPN to anonymize his illegal cyberstalking activities.

Use of VPNs in Certain Countries

Some countries have restrictions or outright bans on VPN use, especially those with stringent internet censorship laws. As of 2023, countries like China, Russia, Iran, and North Korea have restrictions or bans on VPN use. For instance, in China, only government-approved VPNs are allowed, and using an unapproved VPN can result in fines or other penalties.

Bypassing Geo-Restrictions

Many people use VPNs to bypass geographical restrictions on content, which can raise legal and ethical issues. This practice may violate the terms of service of the content provider. For example, Netflix’s terms of service state that users should only access content in the country where they are located and that it reserves the right to terminate accounts that violate this policy.

Corporate and Institutional Policies

Many companies and educational institutions have policies against the use of VPNs on their networks. These policies are in place to ensure network security and compliance with content licensing agreements.
