What are some types of QR Code scams?

Quishing or QR Code phishing is when hackers trick users to exfiltrate their sensitive data . 

Upon scanning a malicious QR Code, uninitiated users submit their private information or download malware onto their mobile devices. 

QR Code scams are often of three types:

1. A fraudulent QR Code that leads to a website that prompts users to enter their personal information like credit card numbers
2. Fake QR Codes that initiate the download of a malicious software on your mobile
3. Scanning a QR Code that takes you to fake offers like rewards and discounts that don’t exist

It is due to these scams that authorities the world over, including the FBI, have issued a warning against malicious QR Codes.

How to check if a QR Code is safe 

Be it a restaurant, a parking meter or a suspicious email, a QR Code scam may be anywhere. But instead of avoiding QR Codes altogether, here are a few ways to ensure your next QR Code scan is not a scam:

1. Use safe QR Code scanning apps (if required)

There was a time when you needed to download an app to scan QR Codes. 

Today, however, if you have an Android (8 and above) or an iOS (11 and above), you simply need to point your native camera app to the QR Code to scan it. 

If a QR Code requires you to download a scanning app, it might be a scam as these third-party apps ask for permissions unrelated to scanning a QR Code. It is also a sneaky way to hide malware.

2. Check the source of your QR Code

QR Code phishing emails have become increasingly common. These emails might contain a fraudulent QR Code that hides malware. 

Some hackers might impersonate a brand, making it tricky to spot a fake. This is why it is essential to inspect the sender’s email address closely and check if the domain is blacklisted, and avoid scanning QR Codes from unknown sources altogether.

3. Check the design and branding

Most brands create customized QR Codes based on their branding. They might add their logo to the QR Code, use brand colors etc., to trigger brand recall, and as a trust-building component.

Additionally, the content that the QR Code redirects to should ideally have the brand’s URL, logo and design elements in the final destination. 

A big red flag is when the website doesn’t contain any branding. In fact, if you see grammatical errors and typos, consider it a warning.

4. Check for any evidence of tampering

Scammers are known to replace authentic QR Codes with fraudulent ones by sticking their fake QR Code over the original design. 

These new QR Codes can redirect you to phishing websites that can steal all your personal information. 

Simply put, one must watch out for any tampering of QR Codes especially on restaurant menus and outdoor advertising. 

5. Examine and preview the URL

Fake QR Codes often lead to a phishing website or an illegitimate app designed to either capture your personal information or steal money. 

Instead of scanning a suspicious QR Code, it makes sense to first preview the URL and check if it is a secure website. 

Secure websites include HTTPS in their web address and not HTTP. They also appear with a padlock sign symbol near the URL. 

On the other hand, a malicious domain might use an incorrect spelling of the intended brand name or a misplaced letter.

What to do if you’ve scanned a fraudulent QR Code

If you’ve already entered some sensitive information and realized that you might have been the victim of a scam, take these steps immediately:

1. Change your passwords and use two-factor authentication software to important accounts. This is important if you think your personal data could have been accessed. 
2. Inform your bank to let them know of a potential scam so that preventive measures can be taken. The bank can block your account and even help you set up a new one if needed. 
3. Sign-up for a virus or identity theft protection software to safeguard yourself. Such a software is designed to detect, prevent and remove any kind of threat to your data.
