FORENSIC ANALYSIS OF CRYPTOCURRENCY TRANSACTIONS: INSIGHTS FROM ANDROID DEVICES CONNECTED TO HARDWARE WALLETS

Tóm tắt

While blockchain ledgers publicly record cryptocurrency transactions, the anonymity of transaction participants presents challenges for forensic investigation. This study concentrates on analyzing android device-based cryptocurrency transactions tethered to hardware wallets: D'cent Biometric Wallet and Ledger Nano S. Through meticulous scrutiny of artifacts produced by these tools – we engineered CryptoInfoGetter; an application designed to extract data related to cryptocurrencies. We developed the tool 'CryptoInfoGetter' for extracting cryptocurrency-related data from artifacts generated by two specific hardware wallets--the D'cent Biometric Wallet and Ledger Nano S; this development was a result of our analysis into forensic aspects of Android device-connected crypto transactions. Our analysis unveils valuable insights: wallet details; transaction histories and hardware wallet configurations—these provide pivotal evidence for forensic investigations. We also confront challenges--the dynamic nature of transactions, anonymity features in particular—and deliberate over opportunities to bolster investigative techniques. The advancement of cryptocurrency forensic analysis necessitates indispensable collaboration among researchers, law enforcement personnel, as well as industry stakeholders.
