Common QR Code Security Threats
A QR code looks pretty harmless, but it can be exploited by criminals. Businesses can face a variety of risks, and need to stay vigilant. Let's examine a few of the potential cybersecurity threats, and later we’ll provide tips on how to keep your QR codes safe.
Phishing via QR codes (Quishing)
Phishing is a type of online scam in which criminals impersonate someone you trust to trick you into disclosing personal information, such as passwords or bank details.
Lately, scammers have started using a new trick called quishing. Instead of sending regular links, they send QR codes. These QR codes can be shared in various ways, such as through emails, text messages, social media, or even printed and placed on posters, flyers, or restaurant tables.
When you scan the QR code, it may direct you to a fake website that appears genuine but is actually designed to steal your information. Because you cannot read a QR code just by looking at it, and since we usually scan them quickly with our phones, it’s easy to miss the danger.
Physical QR code replacement
Printed QR codes in public places can be easily messed with or swapped out. Scammers sometimes overlay fake QR codes on top of real ones to trick people into visiting malicious websites. For example, someone trying to pay for parking might scan a fake code and inadvertently enter their card details on a problematic page.
These types of QR code scams now account for over 20% of all online scams, indicating just how common they have become.
Malware and spyware distribution
Some QR codes are made to automatically download harmful files onto your phone the moment you scan them. The big issue here is that you won’t see any warnings or prompts—it just happens in the background.
Scammers hide these QR codes in counterfit posters, discount ads, or event flyers that look real. Then the unknowing victims scan them thinking they’ll get a good deal or useful information, but instead, they end up infecting their phones.
The files that those who are duped accidentally open can include spyware, keyloggers, or viruses that let hackers secretly control their phone. And once that happens, they can watch what their victims are doing on their smartphones, or steal personal information.
Wi-Fi spoofing via QR codes
QR codes make it easy to join a Wi-Fi network by just scanning a code. However, hackers can exploit this by creating fake QR codes that connect your phone or laptop to a compromised Wi-Fi network, also known as an "evil twin" hotspot.
From there, they can spy on your online activities or steal personal information.
QR Code Security Regulations
In 2023, cybersecurity experts warned that QR codes are becoming a bigger risk in both public and private places. With a significant rise in phishing attacks, businesses are being advised to take safety steps to protect their employees and comply with the law.
Many industries have implemented measures to stop people from misusing QR codes. In banking, companies must adhere to strict rules that protect customer data. These rules include GDPR, PCI DSS, and PSD2.
These regulations state that companies must use secure methods to send data, such as using protected QR codes and ensuring device security. In the same way, hospitals and clinics that use QR codes for appointments or vaccine records must follow HIPAA rules to prevent the inadvertant sharing of patient information.
To follow the rules and keep online information safe, businesses should control who can access their systems, protect all data connected to QR codes, and regularly check the devices or systems that use these codes. It also helps to work with QR code providers who include safety and rule-following features in their services.
When you incorporate QR safety steps into how you use these codes, you not only protect your customers but also avoid potential future legal or financial issues.
How To Implement Robust Security Measures for Your QR Codes
Now that you are aware of the dangers, let’s discuss how to protect your QR codes. These tips will help you secure your QR codes and protect your business and customers from emerging threats.
Use a trusted QR code generator
Choose a trusted platform that offers safety features such as secure links (HTTPS), encryption, scan tracking, and access control. This way, you can make your own branded QR codes, update them when needed, see how they’re being used, and make sure every scan is protected.
Monitor QR code activity in real time
Use scan tracking and location alerts. If you see a sudden jump in scans from places you do not expect, it could mean something’s wrong. A central dashboard can help you identify these issues, set up alerts, and take swift action if anything unusual occurs.
Train employees on QR code security
Be sure your team knows the risks and how to use QR codes safely. They should check printed codes often, avoid using dubious QR code tools, and report anything that looks suspicious. Include these steps in your company’s regular cybersecurity training.
Secure physical QR code placements
One of the most common ways attackers trick people is by messing with physical QR codes. To prevent this, use tamper-proof stickers, locked frames, or digital screens that display the code. You can also add your logo or branding to the QR code so people know it’s the real one and not a fake.
Encrypt all linked data
Every website link or file connected to a QR code should be protected with HTTPS (TLS encryption) to ensure security. If the QR code is used for sensitive transactions like payments or logging in, be sure to use two-step verification so only the intended person can access it.
Integrate with mobile device management (MDM)
If your company uses QR codes on employee devices, MDM tools can help keep everything secure. These tools enable you to control which apps are allowed to scan QR codes and ensure that only approved devices can access private or company-specific links.
Perform routine QR code audits
Set up a regular process to manage all your QR codes. Check which ones are still in use, make sure that they lead to the right places, remove any that are no longer needed, and confirm they’re still in the right spots. Doing this helps prevent scammers from misusing old or tampered codes.

Future Trends in QR Code Security
A recent study by Juniper Research shows that people around the world are expected to spend more than $3 trillion using QR code payments by 2025, up from $2.4 trillion in 2022. This 25% increase is mainly because more countries are working to make financial services easier to access and are also offering new ways to pay besides traditional methods.
Obviously, such accelerated growth calls for smarter, better-protected QR code systems. Luckily, some great minds are working on new ideas, and we've outlined a few of them for you here.
- Smarter threat detection with AI. Some QR tools are starting to use artificial intelligence to spot anything strange, like too many scans in a short time or from odd locations. This helps stop scams before they happen.
