IoT Forensics: Investigating the Mobile App of Dahua Technology

Modern smart homes and their habitants are being protected by both CCTV surveillance systems and diverse security devices like motion sensors. Due to their ever-increasing adoption, such appliances may witness incidents occurring to the loT security systems they form. These complex systems can be configured and monitored by simply using a mobile application. Dahua Technology is a manufacturer of such loT devices that offers a variety of applications to utilize with its products. Research related to the forensic analysis of these applications is scarce yet this unexplored piece of evidence may hide the answer to a number of investigative questions. In this paper the mobile application of Dahua Technology is thoroughly examined in both Android and iOS operating systems so as to uncover evidentiary data that may reside within. Making use of the findings of this study authors contributed to FOSS in an effort to assist investigators with their examinations.
