Mobile Forensics: Investigation and Tools

Mobile devices, particularly smartphones, have become integral to daily life. The personal and sensitive information stored on these devices has become hot targets for cybercriminals. Crimes such as mobile banking fraud, online scams and payment fraud are taking new forms daily. Mobile phones are also being used for money laundering operations to transfer or exchange illicit funds through mobile payment platforms. Either way, the involvement of mobile phones in committing crimes or mobile devices being targets of attacks has made them a critical source of digital evidence in forensic investigations. To extract evidence from these devices, mobile forensic tools have become essential for law enforcement agencies to preserve, extract and acceptably analyze data from mobile devices in law courts. An in-depth examination of the current state-of-the-art mobile forensic tools is essential to help the investigators make an informed choice while selecting the tools. This paper explores four mobile forensic tools: Cellebrite UFED, XRY, Oxygen Forensics Detective, and Magnet AXIOM. A comprehensive overview of the tools is presented, focusing on their capabilities, technicalities and shortcomings in the ever evolving mobile ecosystem. Key functionalities such as accessing locked devices, deleted data recovery, app data parsing, cloud storage access, decryption of encrypted data, and timeline generation are discussed to assess the effectiveness of the tools. Even though these tools have become sophisticated over time, they face several technical challenges. No single tool provides a complete solution for mobile forensic investigation. It is recommended that a combination of tools, based on the case-specific requirements, device types and the nature of data extraction, be used. This paper underscores the importance of constant updates, a wide range of device support, and legal compliance to perform mobile forensic tools effectively.
