Digital Forensics Investigation on Xiaomi Smart Router Using SNI ISO/IEC 27037:2014 and NIST SP 800-86 Framework

The factual conditions reinforced by research data show the increasing number of connected smart devices in a house. The interconnection of these smart devices is able to form a smart home ecosystem with capabilities in the form of file sharing services, multimedia services, access to the internet network, to surveillance applications. Today's smart home interconnection is supported by the use of smart routers. The existence of the threat of exploitation of security gaps in the smart home ecosystem requires mitigation steps after cyber attacks on the smart home ecosystem. The research proposes a digital forensic investigation on the Xiaomi Smart Router using NIST SP 800-86 and SNI ISO/IEC 27037:2014 in a smart home ecosystem. Based on the findings in this study, to obtain and secure potential digital evidence from the Xiaomi Smart Router using the live acquisition method through the Xiaomi Smart Router web interface and the Mi Wi-Fi application installed on an Android smartphone. Live acquisition via the Xiaomi Smart Router web interface using web scraping techniques to obtain and secure digital evidence in the form of smart router device logs. Meanwhile, the digital evidence found from the Mi Wi-Fi application is a SQLite database file.
