Quote:Until now, we have seen how different smart home appliances such as refrigerators, TVs and routers could expose our private data, but now you can add another worry to your list —LED light bulb. Don’t laugh! It’s true.

Researchers at UK security firm Context have formulated an attack against the Wi-Fi connected lightbulbs, which is available to buy in the UK, that exposes credentials of the Wi-Fi network, it relies on to operate, to anyone in accessibility to one of the LED devices.

Security vulnerabilities found in the LIFX Smart light bulbs, that can be controlled by the iOS-based and Android-based devices, could allow an attacker to gain access to a “master bulb” and with the help of that they could control all connected bulbs across that network, and help them expose user network configurations.

Along with other Internet of Things (IoTs) devices, the smart bulbs are part of a rising trend in which the manufacturers enclose computing and networking capabilities to their devices so that it can be easily controlled remotely by using a smartphone, computer, and other network-connected device. LIFX ran a popular fundraising campaign in 2012 on Kickstarter, raising more than $1.3 million (£760,000) which was more than 13 times the original goal of $100,000 (£59,000).

But before delivering the smart bulbs to home consumers, the company failed to properly encrypt all data in the wireless protocols it used when enrolling new bulbs on the network. The oversight allowed the researchers to craft messages to the networked bulbs within about 30 meters, forcing them to obtain security credentials used to secure the connected Wi-Fi network.
