What is a malicious QR code called? A malicious QR code is often referred to as a "QRishing" code. These codes are designed to look like legitimate QR codes but redirect users to harmful websites or initiate unwanted actions on their devices. Understanding how to identify and protect against these codes is crucial for maintaining digital security.

How Do Malicious QR Codes Work?

Malicious QR codes exploit the convenience and popularity of QR codes. They often appear in places where users expect to find legitimate codes, such as on advertisements, posters, or product packaging. By scanning these codes, users may unknowingly download malware, be redirected to phishing sites, or have their personal data compromised.

Common Tactics Used in QRishing

• Redirecting to Phishing Sites: Users are taken to fake websites that mimic legitimate ones to steal login credentials or personal information.
• Initiating Downloads: Scanning the code may trigger automatic downloads of malicious software onto the user’s device.
• Triggering Unwanted Actions: QR codes can initiate actions like sending messages or making phone calls without the user’s consent.

How to Identify a Malicious QR Code?

Identifying a malicious QR code can be challenging, but there are several strategies you can use to protect yourself:

• Verify the Source: Only scan QR codes from trusted sources. If a code appears in an unexpected location, be cautious.
• Use a QR Scanner with Security Features: Some QR scanner apps offer security features that check the safety of a URL before opening it.
• Look for Tampering: Check if the QR code is a sticker placed over another code, which could indicate tampering.

Examples of QRishing Attacks

To illustrate the potential risks, consider these real-world examples of QRishing attacks:

• Event Tickets: Scammers have created fake event tickets with QR codes that lead to phishing websites, tricking users into entering payment details.
• COVID-19 Scams: During the pandemic, fake QR codes were used to redirect users to fraudulent websites claiming to offer COVID-19 information or vaccines.
• Restaurant Menus: QR codes on restaurant tables have been replaced with malicious ones that direct users to phishing sites.

How to Protect Yourself from Malicious QR Codes

Staying safe from QRishing involves a combination of awareness and technology:

1. Educate Yourself: Understand the risks associated with scanning unknown QR codes.
2. Use Security Apps: Install apps that provide security checks for QR codes.
3. Enable Security Features: Ensure your device’s security settings are up-to-date to prevent unauthorized actions.
4. Be Skeptical: If a QR code seems out of place or unexpected, verify its legitimacy before scanning.
