How attackers use QR codes
A Quick Response (QR) code is a string of 7,089 digits or 4,296 characters. It can be scanned with a QR scanner or reader that is usually built into mobile device’s default camera’s. The convenience QR codes and mobile devices offer make them an easy target for malicious actors to use QR code malware kits to steal personal credential and financial assets. Since cashless and no-contact transactions will likely remain for the foreseeable future, we offer a few tips below on how users can protect themselves from QR code scams.
Check for misspellings in website URL
Once you scan a QR code look at the URL to make sure there are no misspellings or typos.
Check for overlaid QR code stickers
Check physical QR codes on stickers and posters to make sure they haven’t been pasted over with a fraudulent QR code.
Never download apps directly from QR code
Always use your phone’s app store for a safer download.
Beware of QR codes sent through email
“Quishing” is when a malicious QR code is sent through email in an attempt to bypass email protection. Always verify with the sender.
Only use QR code with trusted merchants
Always use trusted pay merchants and service providers when using a QR code.
Never use codes sent through social media
Even if you know the sender, QR codes sent through social media can come from hacked accounts and should never be used.
