More Than Half of IoT Devices Vulnerable to Severe Attacks

March 11, 2020 / LINDSEY O'DONNELL

More than half of all internet of things (IoT) devices are vulnerable to medium- or high-severity attacks, meaning that enterprises are sitting on a “ticking IoT time bomb,” according to Palo Alto Networks Unit 42 research team. In new research released Tuesday, researchers said that several deep-rooted issues exist around connected devices, both used by general enterprises and in medical environments. At the most basic level researchers found that 98 percent of all IoT device traffic is unencrypted, exposing personal and confidential data on the network. Other issues, like the reliance on outdated legacy protocols and operating systems, are opening up organizations up to older attack techniques that IT teams may not have had to deal with in years. For instance, researchers outlined one attack they discovered of a connected mammogram machine, used in a hospital, by the Conficker worm (malware first discovered more than a decade ago).
