description: As of 2019, nearly 147 million smart speakers were sold worldwide. This increasing popularity of voice-controlled systems amplify the severity of security vulnerabilities in these systems. On November 4, 2019 Sugawara et al unveiled a novel attack using lasers to silently inject commands into voice-controlled systems. The aim of this project is to replicate their attack, entitled light commands in order to assess the threat, scope the severity and feasibility. Design and build a low-cost laser-based audio remote surveillance and command injection system for voice-controlled devices. Implement and discuss the details behind digital signal processing speech filter. Ending with an examination of ways to extend the Light Command attack. The results show that this is not a feasible nor scalable attack as one cannot simply buy the terminal experimental setup and expect it to work. However, everything is vulnerable in some ways, and cannot be assumed safe nor off the table for hacking.
