QR codes can be found almost everywhere, helping people access useful information and other
webpages as fast as they can open their smartphone cameras.
Many of us don’t think twice before scanning them. But to cybercriminals, their pervasiveness presents
a new opportunity; the chance to deploy a sophisticated phishing strain designed to make us let our guard
down while malware is uploaded or sensitive information stolen. After all, no one can verify a QR code is
safe just by looking at it.
