By gaining access to the master bulb, Context was able to control all connected light bulbs and expose user network configurations. The bulb manufacturer LIFX has since worked closely with Context to promptly patch the issue, which is now available as a firmware update. A spokesperson,
Details of the vulnerability and the subsequent fix, have been published today at: contextis.co.uk/blog/hacking-internet-connected-light-bulbs
The work by Context is part of ongoing research into the security of the emerging Internet of Things (IoT) and raises some questions. "It is clear that in the dash to get onto the IoT bandwagon, security is not being prioritised as highly as it should be in many connected devices," said

The fix, developed with the help of Context, is included in the new firmware available at updates.lifx.co and now encrypts all 6LoWPAN traffic, using an encryption key derived from the wifi credentials. It also includes functionality for secure 'on-boarding' of new bulbs on to the network.
The detailed steps of gaining access to the device involved accessing the firmware by physically interrogating the device's embedded microcontrollers to identify and understand the encryption mechanism in use. Armed with knowledge of the encryption algorithm, key, initialisation vector and an understanding of the mesh network protocol, Context was able to inject packets into the mesh network, capture and decrypt the network configurations, all without any prior authentication or alerting of its presence.
"Hacking into the light bulb was certainly not trivial but would be within the capabilities of experienced cyber criminals," said
