The answer is Elcomsoft Phone Breaker, as it is the tool specifically designed to decrypt and display iOS keychain contents from device backups. This tool works by first recovering the backup password through brute-force, dictionary attacks, or GPU acceleration, then leveraging iOS’s Keychain Services API to extract and decrypt stored passwords, tokens, and cryptographic keys. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your knowledge of specialized forensic utilities for mobile data recovery, often appearing in the iOS forensics domain where examiners must distinguish between general backup extractors and keychain-specific decryptors. A common trap is confusing it with tools like Cellebrite or FTK, which handle broader data extraction but lack dedicated keychain decryption. Memory tip: think of Elcomsoft as the “keychain breaker” because it breaks the backup password to break open the keychain.

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.
A forensic investigator needs to analyze the keychain data from an iOS device backup. Which tool is specifically designed to decrypt and display iOS keychain contents?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Elcomsoft Phone Breaker
Elcomsoft Phone Breaker is specifically designed to decrypt and display iOS keychain contents from backups, including passwords, tokens, and cryptographic keys. It leverages techniques such as brute-force, dictionary attacks, and GPU acceleration to recover the backup password, then extracts and decrypts the keychain data using iOS's Keychain Services API.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Elcomsoft Phone Breaker
Why this is correct
Elcomsoft Phone Breaker can decrypt iOS backups and keychain items, including passwords and tokens.
Related concept
Read the scenario before looking for a memorised answer.
✗
Cellebrite UFED
Why it's wrong here
UFED is a comprehensive mobile forensic tool but does not specifically specialize in keychain decryption like Elcomsoft.
✗
Oxygen Forensic Detective
Why it's wrong here
Oxygen Forensic Detective is a mobile forensic tool but keychain decryption is not its primary feature.
✗
Magnet AXIOM
Why it's wrong here
AXIOM is a digital forensic platform that can analyze iOS data but is not specialized for keychain decryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that general-purpose forensic tools like Cellebrite UFED or Magnet AXIOM can decrypt iOS keychain natively, when in fact only specialized tools like Elcomsoft Phone Breaker are designed for that specific task.
Detailed technical explanation
How to think about this question
iOS keychain uses the 256-bit AES-GCM encryption with keys derived from the device's UID and the user's passcode via PBKDF2-AES. Elcomsoft Phone Breaker exploits the fact that iOS backups store the keychain in an encrypted SQLite database (keychain-backup.plist) and uses the backup password to derive the decryption key, often employing rainbow tables or brute-force to recover weak passwords. In real-world scenarios, this tool is critical for accessing encrypted credentials like Wi-Fi passwords, VPN tokens, and app-specific secrets that are otherwise inaccessible.
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.
