QR codes have become an everyday convenience, allowing quick access to websites, payment platforms, and digital menus with a simple scan. However, as their popularity has grown, so has the interest of cybercriminals looking to exploit them. A not-so-new but lesser-known wave of phishing attacks known as “QR phishing” or “quishing” is on the rise, tricking unsuspecting users into scanning malicious codes that can steal personal information, install malware, or redirect to fraudulent websites.
How QR Phishing Works
Cybercriminals have found multiple ways to manipulate QR codes for their scams. One of the most common methods involves placing fake QR codes over legitimate ones. This can happen at restaurants, parking meters, or public spaces where businesses commonly use QR codes for services. When a user scans the fake code, they might be taken to a website that looks legitimate but is designed to steal login credentials, financial information, or other sensitive data.
Another approach involves sending QR codes via email or text messages, claiming to be from a trusted source like a bank, delivery service, or tech support team. These messages often create a sense of urgency, telling users that their account has been compromised or that they must verify a payment. Once scanned, the user is unknowingly handing over their private information to hackers.
According to Online QR Code, a QR code generating tool, there are different types of QR codes and almost every type of code can be abused by scammers. This means that no matter how a QR code is presented, on a poster, in an email, or even on an official-looking document; there’s always a risk if the source isn’t verified.
Why QR Phishing Is So Effective
QR phishing works so well because QR codes themselves don’t immediately show where they lead. Unlike a traditional link, which allows users to hover over and preview the URL, scanning a QR code often takes users directly to the intended site without any immediate warning. On mobile devices, where most QR scans happen, this makes it even easier for scammers to operate undetected.
Additionally, many people trust QR codes because they are widely used by legitimate businesses and organizations. Scammers take advantage of this trust by placing their malicious codes in places where people wouldn’t normally question their authenticity. This is why even the FBI had to issue warnings about QR phishing.
How to Protect Yourself from QR Phishing
While QR phishing is a growing threat, there are simple steps you can take to stay safe:
- Verify Before Scanning – If you see a QR code in a public place, check for signs of tampering. If a sticker looks like it’s been placed over another code, avoid scanning it.
- Preview the URL – Some smartphone cameras and QR scanner apps allow you to preview the link before opening it. If the URL looks suspicious or doesn’t match the expected destination, don’t proceed.
- Avoid Scanning Codes from Emails or Texts – Be cautious with QR codes sent via email or text, especially if the message is unexpected or urgent. Instead of scanning, visit the official website of the organization by typing the address directly into your browser.
- Use a QR Code Scanner with Security Features – Some security apps and QR scanners come with built-in protection that can detect and warn users about malicious links.
- Check for HTTPS and Official Domains – If you do scan a QR code, look at the URL before entering any personal information. Legitimate websites should have “https” in the address, and the domain should match the official website of the company.
- Be Skeptical of Unsolicited QR Codes – If you receive a QR code claiming to offer a prize, discount, or urgent security alert, treat it with suspicion. Scammers often use these tactics to lure victims into scanning.
- Keep Your Phone’s Security Updated – Ensure that your phone’s operating system and security software are up to date. This can help prevent malware infections from malicious sites.
QR codes aren’t going away anytime soon. They’ve become a vital tool in marketing, payments, and everyday interactions. But just like with email phishing and other cyber threats, awareness is key to staying safe. By taking a few extra seconds to verify the source of a QR code before scanning, you can protect yourself from falling victim to these increasingly sophisticated scams.
