What to check when scanning a QR code to avoid scams and hacks ?

QR codes have become part of our everyday lives, making it easy to access information, connect to Wi-Fi, or make payments in a flash. But while these black-and-white squares might seem harmless, they can pose hidden risks if not approached carefully. So, how do you protect your personal data while still benefiting from the convenience of QR codes? Here’s what you need to know.

Are QR Codes a Hidden Security Risk?

You’ll find QR codes everywhere these days—on menus, in advertisements, and even on store receipts. They’re undeniably handy, but they also present an entry point for cybercriminals. When you scan a QR code, it often contains a link to a website, a prompt to download something, or login credentials, meaning a lot is happening behind the scenes with just one click.

If that link directs you to a phishing site or initiates a download, your device could end up compromised, or your personal information could be at risk. Cybersecurity expert Brian Krebs explains that while QR codes themselves are not inherently dangerous, they can be used by scammers to lure users into unsafe actions, particularly since a QR code’s content is invisible until it’s scanned.

How to Verify a QR Code’s Safety

If you’re scanning QR codes regularly, as many of us do, it’s worth taking an extra moment to check the destination before proceeding. Fortunately, a quick review can prevent a lot of potential harm. After you scan a QR code, an abbreviated URL might pop up, which doesn’t always show the full destination. For Android users, long-pressing the URL will reveal the full address. On an iPhone, you can view the complete link by tapping the QR code icon on the right side of the URL preview. This extra step gives you a clear picture of where you’re headed.

If you’re ever unsure about a link, you can copy and paste it into a tool like VirusTotal, a free service that checks for potential risks. This scan can tell you if the site is secure or possibly linked to phishing scams. Staying vigilant with these simple precautions can go a long way toward ensuring your safety online.

Beware of Public Wi-Fi QR Codes

Free Wi-Fi feels like a lifesaver sometimes, especially when you’re out and about, but be cautious with QR codes that promise quick access to public networks. Hackers often set up fake Wi-Fi networks using QR codes to capture your data when you connect. Unfortunately, there isn’t a simple way to check a network’s legitimacy, so it’s best to confirm with a staff member if a public Wi-Fi network actually belongs to the business or venue.

If there’s any doubt about a Wi-Fi network, don’t take the risk. Many cybersecurity experts, including the National Cyber Security Centre (NCSC), advise using only verified networks. Sticking with trusted sources can help you avoid falling prey to a scam that could compromise your personal information or bank account.

As QR codes become more widespread, it’s tempting to scan them without a second thought. But with just a few precautions, you can stay safe and protect your data from potential threats. So next time you reach for your phone to scan, remember: a quick check can make all the difference.
