Computer Hacking Forensic Investigator (CHFI v10) — Question 323

An investigator has found certain details after analysis of a mobile device. What can reveal the manufacturer information?

Answer options

• A. Equipment Identity Register (EIR)
• B. Electronic Serial Number (ESN)
• C. International mobile subscriber identity (IMSI)
• D. Integrated circuit card identifier (ICCID)

Correct answer: B

Explanation

The correct answer is B, the Electronic Serial Number (ESN), as it uniquely identifies the device and indicates its manufacturer. The Equipment Identity Register (EIR) tracks devices on a network, while the IMSI identifies a subscriber and the ICCID identifies a SIM card, but neither directly provides manufacturer information.
