Spam Emails Link To QR Codes - Security Labs（情報元のブックマーク数）
スパムは、今やQRコードも使うらしい。
It was just a matter of time, and now it's happening. The WebsenseR ThreatSeekerR Network has started spotting spam messages that lead to URLs that use embedded QR codes. This is a clear movement and evolution of traditional spammers towards targeting mobile technology.

The spam email messages look like traditional pharmaceutical spam emails (image 1) and contain a link to the Web site 2tag.nl. This is a legitimate Web service that allows users to create QR codes for URLs. Once the 2tag.nl URL from the mail message is loaded in the browser, a QR code is displayed, along with the full URL that the QR code resolves to on the right (image 2). When the QR code is read by a QR reader, it automatically loads the spam URL(or asks before loading, depending on which flavor of QR reader you have installed) (images 3 and 4).
