Quick Response (QR) Code Tampering

What is Quick Response (QR) Code Tampering?

The intentional altering of QR codes to send visitors to potentially dangerous websites or to conduct fraudulent activities is known as QR code tampering.

There are a few techniques to accomplish this, such as overlaying a fake QR code over a real one. For instance, a con artist could print a phoney QR code sticker and apply it over the real one on a product label, a public poster, or a menu at a restaurant. When QR codes are in digital format, they can be edited with image editing software to include malicious URLs, giving the impression that they are reliable but actually directing users to risky websites.

In addition, attackers may design fake QR codes that closely resemble real ones in order to trick people into scanning them. These altered codes frequently lead to phishing websites that collect private or sensitive data, such as login credentials or bank account information. They may also send users to websites that automatically download and install malware on their devices, endangering their privacy and security. Scanning a modified QR code can have serious consequences, ranging from financial losses due to fake payment pages to data theft and privacy violations.

How Do Scammers Execute QR Code Tampering?

  1. Scammers make fake QR code stickers that are designed to look real, and then they physically place them over real QR codes that already exist. This technique is frequently carried out in busy places where many people can scan the codes, including menus at restaurants, billboards, or public information kiosks.
  2. Scammers manipulate QR codes in digital formats such as electronic documents, photos, and webpages by using image editing software. Once shared via email, social media, or other online channels, these hacked QR codes can direct unsuspecting people to dangerous websites.
  3. Fraudsters can generate completely fake QR codes that resemble those from trusted sources. These counterfeit codes might be distributed through flyers, business cards, or advertisements, tricking users into scanning them.
  4. By embedding URLs that lead to phishing websites within QR codes, scammers can trick users into entering sensitive information, such as login credentials, financial details, or personal data. These phishing sites often mimic legitimate websites to appear trustworthy.
  5. Some tampered QR codes direct users to websites that automatically download and install malware on their devices. This malware can then be used to steal information, track activities, or gain unauthorised access to systems.
  6. Scammers often exploit situations where QR codes are trusted and expected, such as during events, in official communications, or on products. By placing tampered codes in these contexts, they increase the likelihood that users will scan them without suspicion.

Signs To Look For in QR Code Tampering

  1. A sticker or label placed over an existing QR code is one way to tell if it has been tampered with. If the QR code appears to be a separate piece glued to a surface, a fake code likely covered the actual one.
  2. Look for differences in the QR code’s logo or design from the surrounding area. It may be suspicious if the QR code’s style, colour, or logo does not complement the general pattern of the material it is printed on.
  3. Look for evidence of tampering, such as scratches, adhesive residue, or defects that suggest a sticker was removed or changed, on the area surrounding the QR code.
  4. Upon scanning a QR code, be sure to read the URL that appears. The URL may be dangerous if it appears out of context, misspells words, or uses an unknown domain.
  5. If the QR code takes you to a website without HTTPS, proceed with caution. A padlock icon in the address bar of a secure website often indicates that it is encrypted and safer to use.
  6. Take into account the environment when you locate the QR code. It could be a warning sign if a code appears in an odd or unexpected place, such as an unwanted email or a random flyer.
  7. When prompted to enter login credentials or provide personal or financial information via a QR code, especially if it does not seem suitable in the given situation, be cautious of such requests.
