Understanding Quishing: Protect Yourself from QR Code Scams

As technology evolves, so do the tactics of cybercriminals. One of the latest threats is quishing, a form of QR phishing that targets unsuspecting users of QR codes. These square barcodes have become increasingly popular, especially during the pandemic, for quickly sharing information, accessing websites, and making payments. However, scammers have found ways to exploit this technology to steal sensitive information, install malicious software, or even siphon off money. In this blog, we will explore what quishing is, how to protect yourself from it, and what to do if you fall victim to a fake QR code.

What Is Quishing?

Quishing is a cybercrime tactic where criminals manipulate QR codes to redirect users to fraudulent websites or download malicious software. When a user scans a tampered QR code, they may unknowingly provide personal or financial information to the scammer, download malware onto their device, or make payments to fraudulent accounts. The effectiveness of quishing lies in the fact that QR codes are unreadable without electronic assistance, making it difficult for users to detect tampering.

Examples of Quishing

Here are three common scenarios where quishing can occur:

• A criminal embeds a fake URL in a QR code, leading the user to a phishing website. The user may then enter personal or financial information, which the scammer can use for identity theft.
• A criminal uses a QR code to install malware on a user’s device. This malware can steal sensitive data, lock files, or demand a ransom to restore access.
• A criminal alters a QR code to gain access to the user’s payment platforms, send fraudulent emails, or follow social media accounts controlled by the scammer.

Where Can You Find Altered QR Codes?

Altered QR codes can be found in various places, including:

• Emails
• Text messages
• Social media posts
• Restaurants
• Bars
• Stores
• Parking meters
• Packages

How to Protect Yourself from Quishing

To safeguard yourself from quishing, follow these eight tips:

1. Be skeptical: Only trust QR codes from recognized individuals or organizations.
2. Watch out for modified QR codes: Check if the QR code appears tampered with, such as a sticker covering a legitimate code.
3. Check the URL: After scanning a QR code, examine the URL to ensure it looks authentic. Suspicious URLs are often short or unreadable.
4. Beware of phony websites: Look for signs of illegitimacy, such as typos, poor design, or lack of security (no https:// or padlock icon).
5. Resist downloading apps via QR codes: Download apps from official app stores to avoid malicious software.
6. Don’t download QR code scanner apps: Use the scanner built into your device’s camera to reduce the risk of malware.
7. Be cautious with data: Avoid entering credit card numbers or login credentials on websites accessed via QR codes.
8. Install security software: Ensure your devices have up-to-date security software to prevent viruses and malware.

What to Do if You Scan a Fake QR Code

If you realize you’ve scanned a fake QR code, take the following steps:

1. Change passwords: Update passwords for any compromised online accounts. Use secure passwords with at least eight characters, including uppercase and lowercase letters, numbers, and symbols.
2. Contact your credit card issuers and banks: Inform them of the potential fraud. They may need to close your accounts and open new ones.
3. Set up a fraud alert and credit freeze: You can request a free fraud alert and credit freeze from the three major credit reporting agencies: Experian, TransUnion, and Equifax. A fraud alert asks companies to verify your identity before extending new credit, while a credit freeze limits access to your credit report.
4. Alert the Federal Trade Commission (FTC): Report identity theft to the FTC. They share this information with law enforcement to help investigate fraud.
5. Consider identity theft protection: Services like Experian’s identity theft protection monitor credit applications, scan the dark web for your information, and perform monthly privacy scans to detect signs of identity theft.

The Bottom Line

Anyone who uses QR codes is at risk of quishing, a tactic used by criminals to steal sensitive information or cause other harm. However, you can protect yourself by carefully examining QR codes before scanning them and only downloading QR codes from trusted sources. By following the tips outlined in this blog, you can reduce the risk of falling victim to quishing scams.
