This CHFI practice question tests your understanding of mobile and malware forensics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which tool is specifically designed to perform physical extraction of data from mobile devices, including bypassing lock screens on many iOS and Android devices?
SIFT Workstation
Why wrong: SIFT is a forensic workstation, not a mobile extraction tool.
FTK Imager
Why wrong: FTK Imager is for disk imaging, not mobile devices.
Cellebrite UFED
Cellebrite UFED specializes in physical extraction and lock screen bypass.
Wireshark
Why wrong: Wireshark is a network protocol analyzer.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cellebrite UFED
Cellebrite UFED (Universal Forensic Extraction Device) is a specialized hardware and software tool designed for physical extraction of data from mobile devices, including bypassing lock screen security on iOS and Android devices. It uses advanced techniques such as bootloader exploits, JTAG, chip-off, and proprietary software-based methods to acquire full file system images, even when the device is locked or encrypted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
SIFT Workstation
Why it's wrong here
SIFT is a forensic workstation, not a mobile extraction tool.
FTK Imager
Why it's wrong here
FTK Imager is for disk imaging, not mobile devices.
Cellebrite UFED
Why this is correct
Cellebrite UFED specializes in physical extraction and lock screen bypass.

Wireshark
Why it's wrong here
Wireshark is a network protocol analyzer.
Common exam traps
EC-Council often tests the distinction between logical extraction (e.g., via ADB or iTunes backup) and physical extraction, and candidates may confuse FTK Imager (a computer forensics tool) with mobile extraction tools, missing that Cellebrite UFED is the only option capable of bypassing lock screens via hardware-level exploits.
Detailed technical explanation
Cellebrite UFED leverages low-level bootloader vulnerabilities (e.g., checkm8 for iOS devices) and Android's fastboot or recovery mode exploits to bypass lock screen protections and perform physical extraction. In real-world scenarios, examiners may use UFED to acquire a full file system from a locked iPhone with a broken screen, where traditional logical extraction fails, enabling recovery of encrypted app data and deleted artifacts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
