Analisis Artefak Digital Aplikasi Dompet Cryptocurrency Tokocrypto pada Android

Abstract

Cryptocurrency wallets are applications that enable cryptocurrency users to store, withdraw, and transfer various digital assets of cryptocurrency. Criminal activities involving cryptocurrency wallets as a container play a role in the challenge of proving and analyzing artifacts or digital objects stored on smartphones. Therefore, this research will conduct forensic investigation on one of the legal cryptocurrency wallet applications in Indonesia, namely the Tokocrypto cryptocurrency wallet application. This study focuses on discovering digital artifacts of the Tokocrypto cryptocurrency wallet from smartphone devices based on facts and information obtained from smartphone clues. To find digital evidence from cryptocurrency wallet applications on smartphones, the DFRWS method is used, which consists of six stages: identification, preservation, collection, examination, analysis, and presentation, along with the forensic tool Oxygen Forensics for acquisition and analysis. Based on the research results, this study aims to analyze the artifacts of the Tokocrypto digital cryptocurrency wallet on Xiaomi Redmi 6A smartphones. The analysis results show that out of ten observed transaction activities, information about seven transactions has been successfully identified, including fiat deposits, fiat withdrawals, crypto withdrawals, and crypto sales. However, some transaction labels such as transaction type, Order ID, Txid, and wallet address are not available for certain transactions. The absence of these labels reduces the level of detail and completeness of information, making it challenging to achieve a comprehensive understanding of transaction activities. This research also highlights the importance of a scientific approach in digital forensic analysis to address such challenges. The absence of transaction labels underscores the need for access to richer data, including relevant transaction labels, to obtain a more comprehensive and accurate understanding. Additionally, a multidisciplinary approach that involves the use of additional metadata evidence from external sources can help fill information gaps and understand incomplete transactions. The research results provide initial insights into transaction activities within the Tokocrypto digital wallet but also emphasize the need for improvements in digital forensic analysis methods to address such challenges in the future.
