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.
Security watchers have already seen spam messages pointing to URLs that use embedded QR codes. Now crooks have gone one step further by printing out labels and leaving them in well trafficked locations.
