In fact, using the Wemo as a sort of “middleman,” our team leveraged this open hole in the network to power a smart TV on and off, which was just one of the many things that could’ve been possibly done.Īnd as of April 2019, the potential of a threat born from this vulnerability seems as possible as ever. What’s more – this smart plug, like many vulnerable IoT devices, creates a gateway for potential hackers to compromise an entire home Wi-Fi network. The team soon discovered an attacker could leverage this vulnerability to turn off or overload the switch, which could overheat circuits or turn a home’s power off. Once our research team figured out how exactly the device was vulnerable, they leveraged the flaw to test out a few types of cyberattacks. As a matter of fact, our McAfee Labs Advanced Threat Research team uncovered a flaw in one of these IoT devices: the Wemo Insight Smart Plug, which is a Wi-Fi–connected electric outlet. When a new IoT device is put on the market, these criminals have a new opportunity to expose the device’s weaknesses and access user networks. Additionally, IoT devices’ poor security standards make them conveniently flawed for someone else: cybercriminals, as hackers are constantly tracking flaws which they can weaponize. However, users can be prone to putting basic security hygiene on the backburner when they get a shiny new IoT toy, such as applying security updates, using complex passwords for home networks and devices, and isolating critical devices or networks from IoT. Their convenience and ease of use make them seem like the perfect gadgets for the whole family.
