A digital forensic examiner receives a computer used in a hacking case. The examiner is asked to extract information from the computer's Registry. How should the examiner proceed when obtaining the requested digital evidence?
Correct Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: In digital forensics, the use of reliable, validated, and widely accepted tools and techniques is critical to maintain the integrity and admissibility of digital evidence. According to the National Institute of Standards and Technology (NIST) guidelines and the Scientific Working Group on Digital Evidence (SWGDE) standards, any forensic process must utilize methods that are recognized by the forensic community and have undergone rigorous testing to ensure accuracy and reliability. Using validated tools helps prevent evidence contamination or loss and ensures that results can withstand legal scrutiny. While proper seizure and witnessing are important, the priority in the extraction phase is to use appropriate, trusted tools. Downloading tools from unauthorized or suspicious sources can compromise the evidence and is not an ethical or legal practice. Reference: NIST SP 800-101 (Guidelines on Mobile Device Forensics) and SWGDE Best Practices emphasize tool validation and adherence to community-accepted methods as foundational principles in forensic examination.
Question 2
An organization believes that a company-owned mobile phone has been compromised. Which software should be used to collect an image of the phone as digital evidence?
Correct Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: Forensic Toolkit (FTK) is a widely recognized and trusted software suite in digital forensics used to acquire and analyze forensic images of devices, including mobile phones. FTK supports the creation of bit-by-bit images of digital evidence, ensuring the integrity and admissibility of the evidence in legal contexts. This imaging process is crucial in preserving the original state of the device data without alteration. FTK enables forensic investigators to perform logical and physical acquisitions of mobile devices. It maintains the integrity of the evidence by generating cryptographic hash values (MD5, SHA-1) to prove that the image is an exact copy. Other options such as PTFinder or Forensic SIM Cloner focus on specific tasks like SIM card cloning or targeted data extraction but do not provide full forensic imaging capabilities. Data Doctor is more aligned with data recovery rather than forensic imaging. Reference: According to standard digital forensics methodologies outlined by NIST Special Publication 800-101 (Guidelines on Mobile Device Forensics) and the SANS Institute Digital Forensics and Incident Response guides, forensic tools used to acquire mobile device images must be capable of bit-stream copying with hash verification, which FTK provides.
