The use of QR codes has skyrocketed, especially with the development of mobile technologies. Our ability to browse the restaurant’s menu and websites, authenticate transactions, and even make payments is made possible by them. They provide a practical link between the real and digital worlds. However, the dark side of the internet has started using QR codes for evil purposes, particularly in phishing and cyberattacks, just like with any other technology.
The Use of QR Codes in Phishing Attacks
The top three business verticals for QR code use are retail and shopping, restaurants & cafes, and healthcare. Attackers substitute phony QR codes that point to phishing websites for real QR codes that might be on fliers, posters, and signs. The users of these websites may then be tricked into installing malware or disclosing personal information.
- Malicious QR codes for mobile devices might direct users to download risky software or programs that compromise their devices.
- Deceptive Promotions: Attackers entice users to scan a QR code by promising false discounts or promotions, which starts a destructive operation.
QR Code Safety Guidelines
- Verify Before Scanning: Look for any signs of tampering before scanning a QR code, especially in public areas. Avoid scanning if you’re unsure.
- Utilize a Secure QR Code Scanner: Several mobile security programs provide built-in QR code scanners to identify dangerous URLs.
- After scanning, always double-check the URL before moving on. Suspicious-looking URLs or typos are common on malicious websites.
- Avoid Downloading Files: Use extra caution if the QR code asks you to download a file. Downloading files shouldn’t be done unless the source is known to you.
- Update the operating system and apps on your device frequently. Routine updates frequently include security fixes that stop malware and phishing efforts.
- Use Two-Factor Authentication (2FA): Having 2FA activated can add extra security, even if attackers get some of your information.
The key is to inform and spread awareness. Let your friends and relatives know cyber-criminals are planting fake and dangerous QR codes around. It takes everyone to be on the lookout.
In this digital age, QR codes provide unmatched convenience, but it’s important to use caution when using them. We can enjoy and utilize the advantages of QR codes without being a target of cyber dangers by being aware and using safe practices. Always keep in mind: don’t scan if you’re unsure!
