Modernizing Authentication — What It Takes to Transform Secure Access REGISTER >
Websense security researchers are warning of spam messages that use QR codes to disguise linked Web sites.
"QR codes are a two-dimensional matrix barcode that can be scanned by a camera phone to link users directly to a website that can host any type of content, malicious or otherwise," writes The Register's John Leyden. "By using QR codes (rather than links) as a jump-off point to spamvertised sites, spammers can disguise the ultimate destination of links as well as improving click-through rates. In particular, the approach helps when it comes to targeting mobile users."
"QR codes could be the next step in mobile malware propagation because the technique offers the 'ultimate URL obfuscator,' according to net security firm Websense, which was the first to warn of the QR code mobile spam ploy," Leyden writes.
