Security Analysis of the LIFX Smart Light Bulb

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/01/security_analys_6.html

The security is terrible:

In a very short limited amount of time, three vulnerabilities have been discovered:

  • Wifi credentials of the user have been recovered (stored in plaintext into the flash memory).
  • No security settings. The device is completely open (no secure boot, no debug interface disabled, no flash encryption).
  • Root certificate and RSA private key have been extracted.

Boing Boing post.
