When the Lights Go Out: Cracking the Sonoff / eWeLink Platforms

Smart lighting and automation have opened up tremendous opportunities in residential architecture and design. Whether in plain sight or hidden under drywall, these convenient and relatively inexpensive intelligent outlets and switches can act as a entry points for bad actors or can be hijacked for fun and profit.

This is the case with a vulnerability discovered in the ITEAD Sonoff / eWeLink platform-as-a-service that manages remote control and connectivity between smart switches, relays, or outlets and the software applications controlling them.

Using this vulnerability, a potential attacker can gain control of random devices and remotely access any functionality they offer.
