QR codes have become commonplace, offering a convenient bridge between the physical
and digital worlds. From restaurant menus to marketing materials, they provide quick
access to information and services. However, as with any technology, there are inherent
risks. QR code scams are on the rise, and scanning an unknown code can lead to phishing
sites, malware downloads, or data theft. At CyberFlow, we’re committed to keeping you
informed and secure. Here’s an in-depth look at how to stay safe when using QR codes.

The Rise of QR Code Scams

QR codes (Quick Response codes) have gained immense popularity due to their ease of
use and the growing reliance on smartphones. They encode information that can be
quickly read by a smartphone’s camera, leading users to websites, apps, or payment
portals. However, this convenience comes with a dark side. Cybercriminals have found
ways to exploit QR codes to deceive users and gain access to personal information.
Scammers can create malicious QR codes that, when scanned, direct users to phishing
websites designed to steal login credentials or personal data. Others might initiate the
download of malware, compromising the security of your device. Some scams even lead to
fraudulent payment pages, tricking users into transferring money. As these attacks
become more sophisticated, it’s crucial to stay vigilant.

Tips to Stay Safe from CyberFlow

To protect yourself from QR code scams, follow these comprehensive tips from
CyberFlow:

1. Verify the Source
Only scan QR codes from trusted sources. Whether it’s a poster, a flyer, or a website,
ensure that the origin is reputable. Official websites, business cards from known contacts,
or printed materials from recognised companies are generally safe. Avoid scanning codes
from random public places or unknown sources.

2. Check the URL
When you scan a QR code, your device will usually display the URL before you proceed.
Take a moment to scrutinise this URL. Look for signs of phishing, such as misspelled
words, strange domain names, or unfamiliar web addresses. If something seems off, don’t
proceed. Instead, manually type the URL into your browser to verify its legitimacy.

3. Use Security Apps
Several security apps can scan QR codes and warn you of potential risks. These apps
analyse the embedded link before you visit it, providing an additional layer of security.
Some recommended security apps include Norton Mobile Security, Kaspersky QR
Scanner, and Avast Mobile Security. These tools can help you identify malicious codes and
protect your personal information.

4. Be Wary of Unsolicited Codes
Scammers often send QR codes through unsolicited emails, text messages, or social
media. These codes might promise gifts, exclusive offers, or urgent actions required on
your part. Be sceptical of such messages, especially if they come from unknown senders.
Remember, if an offer seems too good to be true, it probably is.

5. Physical Inspection
Before scanning a QR code, especially in public places, take a moment to inspect it
physically. Scammers often place fraudulent QR code stickers over legitimate ones to
deceive users. Look for signs of tampering, such as mismatched colours, peeling edges, or
unusual placements. If something looks suspicious, avoid scanning the code.

6. Update Your Device
Keeping your smartphone’s operating system and security software up to date is crucial.
Manufacturers regularly release updates that fix security vulnerabilities and improve
overall device security. Ensure you have the latest versions installed to protect against
exploits that could be triggered by malicious QR codes.

Understanding QR Code Scams

To appreciate the risks fully, it’s helpful to understand the different types of QR code
scams and how they operate.

Phishing Scams

Phishing scams involve directing users to fraudulent websites designed to steal personal
information. A scammer might place a QR code on a flyer that promises free concert
tickets. When scanned, the code leads to a website that asks for login credentials or
payment information. Unsuspecting users may enter their details, which are then stolen by
the scammer.

Malware Distribution

Malware distribution via QR codes is another common threat. Scanning the wrong code
can initiate the download of malicious software onto your device. This malware can steal
data, track your activities, or even take control of your device. This type of attack is
particularly dangerous because it often goes unnoticed until significant damage has been
done.

Payment Fraud

Some scammers use QR codes to facilitate payment fraud. They might replace a legitimate
payment QR code with their own, leading to unauthorised transactions. For example, a
scammer could stick a fake QR code over a restaurant’s payment QR code, directing funds
to their account instead of the restaurant’s.

Staying Informed and Vigilant

Education and awareness are your first line of defence against QR code scams. Stay
informed about the latest trends in cyber threats and adopt a cautious approach to
scanning QR codes. Share these safety tips with friends and family to help them stay
protected as well.

Advanced Protective Measures

Beyond the basic tips, consider implementing advanced protective measures to enhance
your security further.

Use a Dedicated QR Code Scanner

While most smartphone cameras can scan QR codes, using a dedicated QR code scanner
app can provide additional security features. These apps often include safety checks and
can alert you to potentially harmful links before you open them.

Enable Two-Factor Authentication

Two-factor authentication (2FA) adds an extra layer of security to your online accounts.
Even if a scammer obtains your login credentials through a phishing QR code, they would
still need the second form of verification (such as a code sent to your phone) to access
your account. Enable 2FA on all your important accounts to enhance their security.

Regularly Monitor Your Accounts

Keep a close eye on your financial and online accounts for any unusual activity. Early
detection of unauthorised transactions or changes to your accounts can help you respond
quickly and mitigate potential damage.

Educate Yourself Continuously

Cybersecurity is an ever-evolving field. Stay updated on the latest security threats and best
practices by following reputable cybersecurity blogs, attending webinars, and participating
in online forums. Continuous education will help you stay ahead of scammers and protect
your personal information more effectively.

Understand the Risks

QR codes are a valuable tool in our digital lives, but they come with risks. By understanding
these risks and following CyberFlow’s tips, you can enjoy the convenience of QR codes
while keeping your personal information safe. Always verify the source, check URLs, use
security apps, be wary of unsolicited codes, inspect codes physically, and keep your
device updated. Stay informed and vigilant to protect yourself from the growing threat of
QR code scams. Remember, a moment of caution can prevent a lot of trouble. Stay safe
and scan smart!
