Can You Be Hacked Through a VPN? What You Need to Know

Using a VPN does not make you invisible online. While a VPN encrypts your traffic and hides your IP address, it does not protect you from every type of cyberattack. Hackers can still reach you through a VPN if your provider is untrustworthy, your VPN software has unpatched flaws, or your device is already compromised. This guide breaks down exactly how that happens and what you can do to stay protected.

Does a VPN Actually Protect You from Hackers?

A VPN protects you by encrypting your internet traffic and routing it through a secure server. This prevents third parties like your ISP, network admins, or attackers on public Wi-Fi from spying on your browsing activity or intercepting your data in transit.

However, a VPN only secures the connection between your device and the VPN server. It does not protect against malware already on your device, phishing attacks, weak passwords, or a VPN provider that logs and sells your data.

Think of a VPN as a locked armored truck. It protects what is being transported, but it cannot stop someone from breaking into the warehouse before the truck departs or after it arrives.

How You Can Still Get Hacked While Using a VPN

1. Your VPN Provider Is Malicious or Untrustworthy

Not all VPN providers operate with your interests in mind. Free VPN services in particular have a history of logging user data, injecting ads into web pages, and even selling browsing activity to advertisers. Some have been caught distributing malware bundled with their apps.

When you use a VPN, you are routing all your traffic through that provider’s servers. A dishonest provider has full visibility into your unencrypted requests, including the sites you visit and the data you submit before HTTPS encryption kicks in at the destination server.

Always choose a VPN with an independently audited no-logs policy. Providers like Mullvad, ProtonVPN, and ExpressVPN have undergone third-party security audits that verify their privacy claims.

2. VPN Software Vulnerabilities

VPN applications are software, and software has bugs. Researchers have discovered serious vulnerabilities in popular VPN clients over the years. For example, older versions of Cisco AnyConnect and Pulse Secure VPN had vulnerabilities that allowed remote code execution without any credentials.

If you run an outdated VPN client, attackers can exploit known flaws to gain unauthorized access to your device or intercept your traffic before it gets encrypted.

Fix: Keep your VPN application updated at all times. Enable automatic updates if the option is available.

3. DNS Leaks Expose Your Real IP Address

A DNS leak happens when your DNS queries bypass the VPN tunnel and go directly to your ISP’s DNS server instead. This exposes the websites you visit and your real IP address, even though you think you are protected by the VPN.

DNS leaks often occur due to misconfigured VPN settings or OS-level DNS handling overriding the VPN’s DNS servers.

You can test for DNS leaks by visiting dnsleaktest.com while connected to your VPN. If you see your ISP’s DNS servers in the results, you have a leak. Fix it by switching to a VPN that enforces its own DNS servers and blocks outside DNS requests.

4. Misconfigured VPN Settings

A VPN set up incorrectly can leave your traffic exposed. Common misconfigurations include:

• Allowing file sharing while connected to a VPN on a public network
• Using an outdated or weak VPN protocol like PPTP, which uses broken encryption
• Disabling the kill switch feature, which means your real IP gets exposed if the VPN drops

Stick to modern protocols like WireGuard or OpenVPN. Both offer strong encryption and are actively maintained.

5. Malware Already on Your Device

A VPN cannot protect a device that is already infected. If malware is running on your system, it operates at a level that bypasses the VPN entirely. Keyloggers record everything you type, spyware monitors your screen, and remote access trojans give attackers full control regardless of whether a VPN is active.

Scan your device regularly with a reputable antivirus tool like Malwarebytes or Windows Defender and avoid downloading software from unofficial sources.

6. Phishing Attacks

Phishing attacks work by tricking you into handing over your credentials on a fake website. A VPN does not analyze the sites you visit for legitimacy. If you click a phishing link and enter your login details, the VPN offers zero protection because you willingly submitted the information.

Always verify URLs before entering credentials and enable two-factor authentication on all your important accounts.

How to Stay Safe While Using a VPN

Following these steps significantly reduces your exposure to hacking risks while using a VPN:

• Choose a verified no-logs VPN provider: Look for providers that have completed independent security audits, not just self-reported privacy claims.
• Enable the kill switch: This feature cuts your internet connection if the VPN drops, preventing your real IP from leaking even temporarily.
• Use a modern VPN protocol: WireGuard and OpenVPN are the current standards. Avoid PPTP and L2TP without IPsec.
• Check for DNS leaks regularly: Run a DNS leak test every few weeks, especially after VPN updates.
• Keep your VPN client updated: Outdated clients carry known vulnerabilities that attackers actively exploit.
• Use strong, unique passwords: A password manager like Bitwarden makes this easy to maintain across all accounts.
• Enable two-factor authentication: Even if attackers get your password, 2FA stops them from accessing your accounts.
• Keep your operating system and antivirus updated: OS updates patch security vulnerabilities that hackers use to bypass application-level protections like VPNs.
