A person tries to optimize everything and make his life easier. Laziness drives humanity. A washing machine, a robot vacuum cleaner, smart homes have already been invented to help people. The developers strive to tie everything to the smartphone, so that they can manage everything in one click.
Intelligent lamps, which are connected to the Internet and allow you to change light color, are already in use, and users can also schedule them to turn on and off. Despite the advantages of such a device, there is a disadvantage. We use lamps at home and in the office, and hackers can use intelligent lamps to steal data.
Researchers tested cheap smart lamps and concluded they can be used as a covert channel for shielding the user’s personal data. The team used different types of hardware. During the work, the team of researchers connected a mobile phone with the necessary application and changed light colors. The basic plan for exfiltration was the use of light as a channel for transmitting information from a hacked device to the attacker. As a result of the checks, two applications were created: one to send exfiltrated data, and the other to receive data.
The study of this topic is ongoing and it is planned to introduce artificial intelligence. At the moment, methods to control attacks are being developed.
