Industrial IoT cross-layer forensic investigation

SIM card is a basic component for Mobile devices which have function for both identification and authentication of the subscriber phones to its network.  SIM cards themselves contain a repository of data and information such as ICCID, IMSI, Phonebook, SMS, Call detail etc. which have great forensic value. In this article we summarize current forensic research for the data extraction of forensic interest present in SIM cards through a sample tool on window based computer and it is concluded that tools to extract such evidence from the SIM card are exist but there is a need to develop more accurate and sensitive forensically sound tools.

Forensic Analysis of SIM Cards for Data Acquisition

SIM cards as part of smart cards are considered one of the elements found in every mobile phone either smartphone or not. They are used to communicate through the telephone network. SIM cards can be used to track the mobile or to extract user’s data like SMS or phonebook. Moreover, criminal cases involving mobile phone activities are increasing. Therefore, mobile security and analysis is important during the investigation.

Experimental Digital Forensics of Subscriber Identification Module (SIM) Card

With the rapid evolution of the smartphone industry, mobile device forensics has become essential in cybercrime investigation. Currently, evidence forensically-retrieved from a mobile device is in the form of call logs, contacts, and SMSs; a mobile forensic investigator should also be aware of the vast amount of user data and network information that are stored in the mobile SIM card such as ICCID, IMSI, and ADN. The aim of this study is to test various forensic tools to effectively gather critical evidence stored on the SIM card. In the first set of experiments, we compare the selected forensic tools in terms of retrieving specific data; in the second set, genuine user data from eight different SIM cards is extracted and analyzed. The experimental results on a real-life dataset support the effectiveness of the SIM card forensics approach presented in this paper.
