Explore the reverse engineering and security analysis of IoT vape detection devices commonly deployed in school bathrooms through this DEF CON 33 conference talk. Discover how two researchers acquired and thoroughly analyzed a popular line of IoT surveillance devices marketed to educational institutions, beginning with a high school student's network scanning discovery during lunch break. Learn about the complete hardware teardown process, firmware dumping techniques, and behavioral analysis methods used to examine these surveillance devices. Examine the application security vulnerabilities uncovered during the reverse-engineering process and understand their implications for both the specific device series and the broader educational technology surveillance industry. Gain insights into the commoditization of IoT surveillance technology and its impact on student privacy in educational settings. Access practical resources including device filesystem copies, scripts for decrypting OEM firmware, and tools for packing custom firmware updates that will be released alongside this presentation.
