Olga Ivankov VPNs are designed to create a secure and encrypted connection over the internet, masking the user’s IP address and protecting data from prying eyes. Despite their intended purpose, VPNs are not immune to security risks. In this article, we will discuss all you need to know about the security risks with VPNs and what you must stop doing if you’re using a VPN service right now.
What a Recent VPN Security Risk Reports Say
Recent reports highlight significant security risks associated with free VPNs, particularly those available on Android devices. According to TechRadar, over 2.5 billion users of free Android VPNs are at risk due to various vulnerabilities. The report indicates that nearly 90% of these VPNs leak data, and 71% share user data with third parties. This includes sensitive information like IP addresses, DNS requests, and even real-time browsing activities.
One of the major issues identified is the use of outdated and weak encryption protocols. For example, some VPNs still use SSLv2, a 30-year-old protocol, instead of more secure options like IKEv2/IPsec. Additionally, many free VPNs utilize 128-bit encryption rather than the industry-standard 256-bit encryption, compromising data security further.
Another alarming finding is the invasive permissions requested by many free VPN apps. These include access to location data, camera, and even installed apps, which contradicts the fundamental purpose of using a VPN—to protect user privacy. Ads and user-tracking are rampant among these services, undermining the user’s overall experience and privacy.
Stop Doing these If You’re Using VPNs
Here’s what you must immediately stop doing if you’re using VPNs:
1. Using Free VPNs
Let’s talk about free VPNs. Sure, the idea of getting something for nothing sounds great, but in the case of VPNs, you often get what you pay for. Free VPNs tend to have significant limitations, like data caps and slower speeds, which can make streaming or browsing frustrating. But the real kicker is privacy. Many free VPN services fund their operations by collecting and selling your data to third parties. So, while you think you’re protecting your privacy, you might actually be compromising it. Stick with reputable, paid VPN services to ensure your data remains secure.
2. Ignoring Software Updates
We’ve all been guilty of ignoring software updates at some point. However, when it comes to VPNs, this can be a critical mistake. VPN providers regularly release updates that patch security vulnerabilities and enhance the software’s overall performance. By neglecting these updates, you leave your system exposed to potential threats that hackers can exploit. It’s a bit like locking your front door but leaving the back door wide open. Make it a habit to check for updates regularly and install them as soon as they become available.
3. Choosing the Wrong VPN Protocol
VPN protocols are the backbone of your VPN’s security. Think of them as the method by which your data is encrypted and transmitted. Using outdated or insecure protocols like PPTP (Point-to-Point Tunneling Protocol) can leave you vulnerable to security breaches. Instead, opt for more secure and modern protocols like OpenVPN or WireGuard. These protocols offer stronger encryption and better performance, ensuring your data stays protected from prying eyes.
4. Using Weak Passwords
We can’t stress enough the importance of strong passwords. Using weak or easily guessable passwords for your VPN account can be a major security risk. Hackers can use brute force attacks to crack weak passwords, gaining access to your VPN account and potentially all the data you’re trying to protect. Always create strong, unique passwords that include a mix of letters, numbers, and special characters. Additionally, enabling multi-factor authentication (MFA) adds an extra layer of security, making it much harder for unauthorized users to access your account.
5. Not Enabling the Kill Switch
A kill switch is a vital feature that many people overlook. It’s designed to protect your privacy by automatically disconnecting your device from the internet if the VPN connection drops. Without a kill switch, your real IP address could be exposed temporarily, compromising your anonymity. Think of it as a safety net that catches you if your VPN connection fails. Make sure to enable this feature to ensure continuous protection of your online activities.
6. Connecting to Untrusted Public Wi-Fi without a VPN
Public Wi-Fi networks are convenient but notoriously insecure. Hackers often set up fake hotspots or use tools to intercept data on these networks. Connecting to public Wi-Fi without a VPN is like broadcasting your private information to anyone within range. Always ensure your VPN is active before you connect to public Wi-Fi. This encrypts your data and shields it from anyone trying to snoop on your connection.
7. Ignoring DNS Leaks
DNS leaks can undermine the effectiveness of your VPN by exposing your browsing activity to your ISP or other third parties. Even if your VPN is encrypting your data, a DNS leak can reveal the websites you visit. Use tools to check for DNS leaks and make sure your VPN service has built-in DNS leak protection. This ensures that all your DNS requests are routed through the encrypted tunnel, keeping your online activities private.
8. Failing to Verify the VPN’s No-Logs Policy
A no-logs policy means the VPN provider does not keep records of your online activities. However, not all VPN providers are transparent about their logging practices. Some may claim to have a no-logs policy but still collect certain data. It’s important to choose a VPN that has been independently audited to verify its no-logs claims. Trustworthy VPNs often publish these audits, providing peace of mind that your data isn’t being tracked or stored.
9. Using the Default Settings
Default settings are convenient, but they may not always be optimized for your security. Many VPN apps come with default settings that might not offer the best protection. Customize your VPN settings to enhance security and performance. For instance, enable the kill switch, choose a secure protocol like OpenVPN or WireGuard, and set up split tunneling if necessary. Taking a few minutes to adjust these settings can significantly improve your VPN’s effectiveness.
10. Assuming Complete Anonymity
It’s easy to fall into the trap of thinking that using a VPN makes you completely anonymous online. While VPNs do enhance your privacy by masking your IP address and encrypting your data, they don’t make you invisible. Other tracking methods, like cookies and browser fingerprinting, can still identify you. To boost your anonymity, use additional privacy tools like privacy-focused browsers, clear cookies regularly, and avoid logging into personal accounts while connected to the VPN. Remember, a VPN is just one part of a broader strategy to protect your online privacy.
