Malicious QR codes pop up on traffic-heavy locations

Cybercrooks are putting up stickers featuring URLs embedded in Quick Response codes (QR codes) as a trick designed to drive traffic to dodgy sites.

QR codes are two-dimensional matrix barcode that can be scanned by smartphones that link users directly to a website without having to type in its address. By using QR codes (rather than links) as a jump-off point to dodgy sites, cybercrooks can disguise the ultimate destination of links.
