Don’t Let a QR Code Lead You Astray: The Rise of “Quishing”
QR codes are everywhere these days – menus, advertisements, payment terminals. They’re convenient, fast, and generally helpful. But what if that quick scan leads you down a rabbit hole of deception?
Welcome to the world of QR code phishing, or “quishing.” This increasingly popular social engineering tactic leverages our trust and desire for speed. Cybercriminals are embedding malicious links into fake QR codes, often mimicking legitimate ones, to trick you into:
• Visiting phishing websites: These look like real login pages (banks, social media, email) but are designed to steal your credentials.
• Downloading malware: A seemingly harmless scan could install harmful software on your device.
• Giving away personal data: You might be prompted to enter sensitive information, thinking you’re interacting with a genuine service.
Why is quishing so effective? Because we tend to drop our guard. We trust QR codes because they’ve become part of our daily lives. Plus, it’s harder to inspect a QR code’s destination with the naked eye compared to a traditional URL.
How to Protect Yourself from Quishing:
1. Stop and Think: Before scanning, consider the source. Is it a legitimate, expected QR code, or does something feel off? Be extra cautious with QR codes on public posters, random flyers, or those sent via unsolicited emails/texts.
2. Inspect the Physical Code: If it’s a sticker placed over another QR code, or if the quality looks poor, it’s a huge red flag. Attackers often overlay fake codes on top of real ones.
3. Use a Secure Scanner App (If Possible): Some dedicated QR code scanner apps allow you to preview the URL before navigating to it. This gives you a chance to spot suspicious links. Your phone’s built-in camera usually goes directly, so an app can add a layer of safety.
4. Verify the URL After Scanning: Once you scan, and before you enter any information, always check the URL in your browser. Look for misspellings, strange domains (e.g., amaz0n.com instead of amazon.com), or non-secure http:// connections (look for https://).
5. Be Wary of Urgent Requests: If the QR code leads to a page demanding immediate action, personal info, or payment due to an “issue,” it’s likely a scam.
As cybersecurity professionals, we often talk about complex attacks, but sometimes the most effective ones exploit simple human trust. Let’s make “think before you scan” a new cybersecurity mantra.
