Correct answer & explanation
✓
GrayKey
GrayKey is a specialized forensic tool developed by GrayShift that performs physical extraction on iOS devices, including bypassing passcodes and obtaining full file system images. It exploits hardware and software vulnerabilities in iOS to extract data, making it the correct choice for this specific task.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Cellebrite UFED's broad device support with the specific ability to perform physical extraction and passcode bypass on iOS, but Cellebrite's iOS capabilities are more limited compared to GrayKey's specialized focus.
Detailed technical explanation
How to think about this question
GrayKey leverages the Device Firmware Upgrade (DFU) mode and exploits the Secure Enclave's limited brute-force protection to bypass passcodes, often using a combination of software and hardware attacks. In real-world scenarios, GrayKey is used by law enforcement to access locked iPhones, even those with the latest iOS versions, by exploiting vulnerabilities like checkm8 or other bootrom exploits. This tool can extract encrypted file system images and decrypt them if the passcode is known or bypassed, providing access to user data such as messages, photos, and app data.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
