Google issues urgent warning to millions of VPN users about serious security threat – what YOU must do

However, fraudsters are using fake apps that are rapidly spreading across multiple platforms, which are targeting billions of smartphone and computer users worldwide. Instead of safeguarding your internet connection as promised, they're actually designed to compromise your security and privacy.

The malicious software poses as legitimate VPN services, often copying the names and branding of some of the best VPNs to deceive unsuspecting users into downloading them.

Once you install these counterfeit applications, they unleash dangerous malware onto your device. The malicious software can steal your passwords, financial credentials, and even access your cryptocurrency wallets without your knowledge.

"These apps often appear genuine and even perform basic VPN functions," explained Laurie Richardson, Google's vice president of trust and safety. "But behind the scenes, they can compromise passwords, banking details and private messages."

The fake VPNs deploy various types of malware, including info-stealers, remote access trojans and banking trojans. These programmes secretly harvest your browsing history, private communications and stored login details.

Your personal information is then transmitted to cybercriminals who can use it for identity theft, financial fraud, or sell it on the dark web.

The timing of this warning is particularly significant as VPN usage has surged following new online safety regulations.

For example, the UK's Online Safety Act and similar US state legislation have introduced age-verification requirements for adult content websites, prompting many users to seek VPN solutions to bypass these restrictions.

Cybercriminals have recognised this opportunity and are specifically targeting vulnerable users through sexually explicit advertising.

If you want to install a VPN on your device to secure your browsing, make sure to stick with the most trusted brands. ExpressVPN has earned dozens of awards from industry publications like Techradar and Cnet. But it's not the only widely-recognised VPN service, with NordVPN also earning a truckload of industry plaudits. Surfshark is another popular choice, especially for those on a tighter budget.

Google said in a statement, "These actors tend to impersonate trusted enterprise and consumer VPN brands or use social engineering lures, such as through sexually suggestive advertising or by exploiting geopolitical events, to target vulnerable users who seek secure internet access."

If you've recently downloaded a VPN to access restricted content, you could be at particular risk from these sophisticated scams.

To protect yourself from these malicious applications, it's best practice to only download VPNs from official sources. Google recommends using verified app stores like Google Play, where applications display a VPN badge to confirm their legitimacy.

It's also best practice to avoid free VPN offers and never sideload apps from untrusted sources.

Some free or disreputable VPNs have been known to log data, sell information on your browsing habits, or expose you to malware. Paid services from well-known providers are usually more secure, offering stronger encryption protocols and privacy policies that prioritize user security.

That said, a VPN is not a foolproof solution. Always ensure that you access your bank's website through its official domain and use two-factor authentication (2FA) where possible to further safeguard your accounts.

Ms. Richardson emphasised that while VPNs can mask your IP address, they don't guarantee complete anonymity online. "A VPN can mask your IP address, but it doesn't make you invisible," she cautioned, advising users to remain sceptical of any service promising total privacy.
