Orome1 writes "QR codes are very handy for directing users to specific sites by simply scanning them with their smartphones. But the ease with which this technology works has also made it a favorite of malware peddlers and online crooks, who have taken to including QR codes that lead to malicious sites in spam emails. They have also begun using the same tactic in the physical world, by printing out the malicious QR codes on stickers and affixing them on prominent places in locations where there is a lot of foot traffic. According to Symantec Hosted Services director Warren Sealey, these locations include airports and city centers, where the crooks stick them over genuine QR codes included in advertisements and notices, and most likely anywhere a person might look and be tempted to scan them."
