Quick Answer
The answer is Cellebrite UFED, the correct tool for Android logical acquisition via ADB. This is because UFED leverages the Android Debug Bridge (ADB) protocol to communicate with a device’s operating system over USB debugging, allowing forensic examiners to extract call logs, contacts, SMS, and application data without invasive chip-off methods. On the Computer Hacking Forensic Investigator (CHFI) exam, this question tests your understanding of non-destructive logical acquisition techniques, often contrasting UFED with tools like JTAG or physical imaging. A common trap is confusing ADB-based logical extraction with more invasive methods; remember that logical acquisition via ADB requires USB debugging to be enabled and does not recover deleted files. Memory tip: “UFED uses ADB for the logical grab—no chip-off, just a USB cab.”
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 can be used to extract evidence from Android devices through the Android Debug Bridge (ADB) and is often used for logical acquisition?
Cellebrite UFED
Supports ADB logical acquisition for Android.
PEiD
Why wrong: Windows packer identifier, not mobile.
Cuckoo Sandbox
Why wrong: Malware dynamic analysis, not mobile acquisition.
GrayKey
Why wrong: Primarily for iOS physical extraction.

Correct answer & explanation
Cellebrite UFED
Cellebrite UFED (Universal Forensic Extraction Device) is a widely used forensic tool that leverages Android Debug Bridge (ADB) to perform logical acquisition of Android devices. ADB allows the tool to communicate with the device's operating system via USB debugging, enabling extraction of call logs, contacts, SMS, and application data without physical chip-off. This makes it the correct choice for logical acquisition over ADB.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the distinction between logical acquisition (via ADB) and physical acquisition (via JTAG or chip-off), and candidates may confuse GrayKey (iOS-focused) with Android tools because both are used for mobile forensics.
Detailed technical explanation
Logical acquisition via ADB relies on the device having USB debugging enabled and the appropriate ADB drivers installed; the tool sends commands like `adb backup` or `adb pull` to extract data from accessible partitions. A subtle behavior is that ADB logical acquisition cannot recover deleted data or access protected storage areas (e.g., /data partition without root), making it suitable only for unlocked, user-accessible data. In real-world scenarios, examiners must ensure the device is in 'File Transfer' mode and that the ADB authorization prompt is accepted on the device screen.
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.
