Tips On Protecting You From Malicious QR Codes | Protect From Malicious QR Codes

What is a QR Code?

A QR (Quick Response) code is a two dimensional barcode, a wonderful marketing tool as it is able to store lots of information.  Consumers / clients can take out their handy smartphones and scan the QR code to directly access coupons, discounts, information, etc.  This saves the consumer / client the agony of manually inputting the website URL.

For a creator of QR code, you can basically generate 2 types of QR code:

Static QR Code: The exact destination website URL is placed directly into the QR code and no modifications are allowed to the destination URL.

Dynamic QR Code: Rather than placing the exact destination website URL into the QR code, a short URL or redirection link is placed into the QR code.  Thus, with the redirection link intact, the destination website URL could be changed even after the QR code has been created.

Convenience but dangers lurk

With usage of QR code gaining more traction (refer to the Q1 2014 Code Scan Volume by QRStuff below), criminals have also discovered that they can make use of QR code to:

–        Infect your smartphone with Malware

–        Trick you to a phishing site

–        Steal your private information stored in your smartphone

Protecting yourself against Malicious QR codes

Follow some or all of these tips to better safeguard yourself against malicious QR code:

  1. Use a QR scanner / reader with built-in security.
  2. Disable ‘Auto Open’ feature in scanner / reader.
  3. Make sure there is no sticker overlaying the original QR code.
