QR codes have a variety of uses, from storing bank information for payments to ordering at restaurants or joining a WiFi network.
But the easy-to-use codes don’t come without security risks. While QR code technology itself is inherently safe, we must be wary of the ways cyber attackers could exploit these codes for nefarious gains, especially as our reliance on them grows.
Essentially, QR codes can serve as URLs, offering the same kind of risks as opening a malicious website on a phone. But unlike a URL, people are less likely to recognize a malicious QR code. Beyond URLs, it also benefits the bad guys that most people don’t know that a QR code can write an email or text message or even make a phone call.
Dynamic QR codes are a special risk. The data stored on them can be changed after they’re generated, or they can present different data to different types of devices.
There are several ways to minimize the risk of QR code scams and QR code security issues:
• Ensure that any QR code reader app that you download is from a reputable source.
• If anyone appears to send a QR code, contact the supposed sender and ask if they sent it.
• Look out for URL-shortened links appearing after scanning a QR code, which can hide malicious URLs.
• Avoid using a QR code to pay a bill. There are many other payment methods that are less susceptible to fraud.
• Consider adding protection that checks for malicious or inappropriate content like RedFox Mobile Security app.
