Question
A security firm investigating an IoT-based cybercrime involving an Android smartwatch found on the crime scene. The smartwatch is suspected of capturing sensitive information such as PINs and passwords through motion sensors and GPS tracking. The paired smartphone is not available. Which of the following steps should the investigator undertake first to proceed with the forensics process effectively?
A. Extract data from the smartwatch’s memory before it gets volatile
B. Identify APIs like Data API, Message API, and Node API on the smartwatch
C. Generate forensic images of the evidence found on the crime scene
D. Look for cloud data and mobile data linked to the smartwatch
Answer
When beginning a forensic investigation of an IoT-based cybercrime involving an Android smartwatch, the most important first step is:
C. Generate forensic images of the evidence found on the crime scene
Explanation
In any forensic investigation, especially when dealing with digital evidence like IoT devices, the top priority is to properly document, collect, and preserve the evidence in its original state. This is critical to maintain the integrity of the evidence and ensure it will be admissible in court.
The first action should be to thoroughly document the crime scene and then generate forensic images of the smartwatch and any other relevant evidence. A forensic image is an exact, bit-for-bit copy of the device’s storage, including deleted and hidden data. Creating this forensic copy preserves the evidence in its original state and allows the investigator to conduct analysis on the copy without risk of altering or damaging the original device.
Extracting data directly from the smartwatch’s memory (choice A) before proper documentation and imaging risks losing volatile data or altering the original evidence. Identifying APIs on the smartwatch (choice B) and looking for associated cloud or smartphone data (choice D) are important steps that can provide valuable information, but should be done after the evidence is documented and imaged.
In summary, the crucial first step is to generate a forensic image of the smartwatch to create an exact copy of the evidence that can be analyzed without altering the original. This preserves the integrity of the evidence, which is paramount in any forensic investigation.
