Taking a random selection of the latest Internet-of-Things (IoT) products, Kaspersky Lab researchers have discovered serious threats to the connected home. These include a coffeemaker that exposes the homeowner’s Wi-Fi password, a baby video monitor that can be controlled by a malicious third-party, and a smartphone-controlled home security system that can be fooled with a magnet.
In 2014, Kaspersky Lab’s security expert David Jacoby looked around his living-room, and decided to investigate how susceptible the devices he owned were to a cyberattack. He discovered that almost all of them were vulnerable. Following this, in 2015 a team of Kaspersky Lab antimalware experts repeated the experiment with one little difference: While Jacoby’s research was concentrated mostly on network-attached servers, routers and Smart TVs, this latest research was focused on the various connected devices available on the smart home market.
The devices selected for the experiment were as follows: a USB-dongle for video streaming, a smartphone-controlled IP camera, a smartphone-controlled coffee maker, and a smartphone-controlled home security system. The investigation discovered that almost all of these devices contained vulnerabilities.
“A baby-monitor camera in the experiment allowed a hacker, whilst using the same network as the camera owner, to connect to the camera, watch the video from it and launch audio on the camera itself. Other cameras from the same vendor allowed hackers to collect owner passwords and the experiment showed it was also possible for a hacker on the same network to retrieve the root password from the camera and maliciously modify the camera’s firmware,” a Kaspersky Lab news release said.
“When it comes to app-controlled coffeemakers, it’s not even necessary for an attacker to be on the same network as the victim. The coffeemaker examined during the experiment was sending enough unencrypted information for an attacker to discover the password for the coffeemaker owner’s entire Wi-Fi network,” it said.
When looking at a smartphone-controlled home security system, Kaspersky Lab researchers found that the system’s software had just minor issues and was secure enough to resist a cyberattack. Instead, the vulnerability was found in one of the sensors used by the system.
“The contact sensor, which is designed to set off the alarm when a door or a window is opened, works by detecting a magnetic field emitted by a magnet mounted on the door or window. When the door or window is opened the magnetic field disappears, causing the sensor to send alarm messages to the system. However, if the magnetic field remains in place, no alarm will be sent,” the release said.
