YET ANOTHER REASON TO BE SKEPTICAL OF THE “INTERNET OF THINGS.” “Attacks that take down websites by flooding them with traffic have been popular among computer criminals for years. Traditionally, such assaults are launched using PCs infected with malware. But two security companies say they have seen the emergence of a worrying new tactic: home routers, Internet-connected printers, and even webcams being used to knock targeted sites offline. In a report released last week, Chinese security company NSFocus said that it had seen a significant increase in the use of networked home and office devices in so-called denial-of-service attacks.” Not surprising, as the security on these devices is often poor.
