While the use of QR codes is increasing day by day, the concerns related to the safety of users are also rising. Though some people believe QR codes to be secure, scanning any random QR code can lead to fraud. Here is what you need to be aware of and why.
Are QR Codes Really Safe?
The answer is yes and no. When scanned with caution, there is no better and more efficient option than QR codes. However, a second of carelessness can transfer your private information to cybercriminals.
QR codes emerged as a quick way of contactless payment, and many people have benefited from them. Also, leading users to specific websites and landing pages are a common purpose of QR codes.
However, these benefits have probable repercussions if you are not careful. QR codes are prone to phishing and malware attacks. Cybercriminals can embed harmful files or links in the QR codes, and as soon as you scan them, you fall prey to a cyberattack.
Potential Hazards Related to Malicious QR Codes
Now that you know QR codes are not really safe, you must be curious about the hazards of malicious QR codes. So, what can you expect if you scan a malware-embedded QR code?
Malware-Injected Fake Websites
With increasing awareness about cyber security, people are less likely to fall prey to malicious websites. So, a way of luring people to such websites is by creating fake QR codes. The destination of these QR codes is a harmful website.
So, when users scan these QR codes out of curiosity or any other reason, their device becomes prone to cyber-attacks. The attacker can steal their personal and important information and use it against them.
Virus-Containing Files
Another potential hazard of fake QR codes is virus-containing files. These files contain malware that can damage a victim’s device and steal its information. The virus is downloaded to their device whenever users scan random QR codes.
Besides stealing data, the virus can spread to different applications and lead to ransomware. Though people believe QR code scanners have built-in virus-detecting features, you must ensure that the specific reader you are using offers this facility.
If not, you should download a virus-detecting application on your device to keep your data safe from such attacks.
Phishing
Phishing is a specific term for websites that pretend to be legitimate and ask for your personal information, specifically your credit card details. QR codes are also prone to phishing. Attackers can place QR codes and promote them in a way that they seem authentic.
Once you scan these QR codes, they will lead to a page where you have to fill in your personal information, for example, your credit card number. If you do so, they get access to your accounts. And they can use this access in any harmful way.
5 Things to Look Out for When Scanning QR Codes
Here are some helpful tricks to avoid getting scammed when scanning QR codes.
The Environment
The first question you should ask yourself while scanning a QR code is – is it usual for QR codes to be found in such places. For example, wouldn’t its authenticity be doubtful if you get across a QR code claiming to lead you to a grand prize while walking down the alley?
So, the environment in which you find a QR code tells you a lot about it. You just need to focus. According to a survey conducted among QR code users, common locations they scanned QR codes were restaurants(37.6%) and retailer shops(37.2%).
So, don’t scan random QR codes placed in unusual places.
Sticker Replacements
Another way of spreading fake QR codes among people is by replacing authentic QR codes with fake. Cybercriminals do it by placing stickers of fake QR codes over the actual QR code on promotional pamphlets.
So, whenever you come across a replaced QR code, that’s a foreshadowing you might get scammed.
Don’t Fall a Prey to Curiosity.
Never scan a QR code just because you are curious about what it might contain. Cybercriminals use a common tactic to lure people into scanning malicious QR codes: claiming something curious. Once you scan a harmful QR code, there is no going back.
So, be cautious.
The QR Code Reader
The QR code reader you are using also plays a significant role in preventing you from malicious codes. As it is the first line of defense, make sure you choose a credible QR code that stops harmful QR codes from getting scanned.
Consider Alternate Ways, if Available
Scanning a QR code should be your last option if other ways are available to complete a task, especially while processing payment.
According to a survey conducted in Japan, 33.3% of the respondents used QR payments. It is considerably high, keeping in view other options are available. So, you should not risk your payment details only because paying with QR codes is comparatively effortless.
The Solution
Not all QR codes are secure, and some tricks help you find which QR code is reliable. However, there should be a permanent solution, which is as follows:
For Users; Keep Your Eyes Open
The only solution for users who often have to use QR codes is to be insightful. Keep your eyes open, and don’t scan any random QR code that seems doubtful to you. Whether it is the location of the QR code or you get a hunch it is not a good idea, don’t do it.
For additional security, ensure your QR code reader is secure and detects malicious codes. Also, install virus-detecting software on your device.
For Businesses; Find a Reliable QR Code Generator
Other than users, businesses also play a significant role in ensuring the safe use of QR codes. So, if you are a business offering QR codes, ensure you offer your users a credible and secure service.
So, choose an authentic QR code generator, such as Unitag. Only a secure QR code generator can help you address your customers’ security concerns. Moreover, dynamic QR codes from Unitag have their domain names whitelisted with Apple and Android devices.
