To ensure the safety of QR codes, it is essential to follow best practices for their usage and implementation. Here are three key best practices for QR code safety:

  1. Personalized targeting techniques: Attackers often use highly personalized targeting techniques to trick individuals into scanning malicious QR codes. This means that you should be cautious when scanning QR codes that come from unfamiliar or suspicious sources. Always verify the source and ensure that it is trustworthy before scanning.
  2. QR code authentication methods: Implementing QR code authentication methods can add an extra layer of security. This involves using tools or services that authenticate the QR code before it is scanned, ensuring that it is legitimate and not malicious. Look for QR code scanners or apps that provide this feature and use them whenever possible.
  3. Trustworthy sources: Only use QR codes from trusted sources. This means scanning QR codes from reputable companies, organizations, or individuals that you know and trust. Avoid scanning QR codes from random sources or those received through unsolicited messages, as they may lead to phishing attempts or malware infections.

Personalized Targeting and Sender Domains

Personalized targeting and sender domains play a crucial role in the effectiveness of QR code phishing attacks. Attackers often employ customized scams, tailoring their messages to specific targets to increase the likelihood of success. In addition, they frequently impersonate legitimate senders, such as internal IT teams, to deceive recipients and gain their trust. This social engineering technique enhances the credibility of the phishing attempt and increases the chances of victims falling for the scam.

Traditional security measures, such as those relying on known-bad lists and signature-based detection, struggle to detect these attacks due to their personalized nature. Therefore, individuals should exercise caution and only scan QR codes from trusted sources to mitigate the risks associated with personalized targeting and sender impersonation.

Social Engineering Techniques With Malicious QR Codes
