Prepare for the Computer Hacking Forensic Investigator certification with CHFI practice exam questions covering evidence handling, digital forensics methods, file systems, malware investigation, network evidence, mobile artifacts, and incident response reporting. The questions are scenario-based so you can practice choosing the next forensic step.
As you review, focus on chain of custody, artifact locations, acquisition methods, and tool limitations. Those details are easy to confuse under time pressure, and repeated practice with explanations helps turn forensic terminology into exam-ready judgment.
The Computer Hacking Forensic Investigator (CHFI) certification, offered by EC-Council under exam code 312-49, validates a practitioner's ability to detect hacking attacks, conduct thorough digital forensic investigations, and extract and preserve evidence in a manner admissible in legal proceedings. The program covers the full forensic investigation lifecycle — from searching and seizing digital assets through chain-of-custody procedures, data acquisition and duplication, defeating anti-forensic techniques, and final reporting. CHFI v11 is the current version of the program and introduced new modules on Dark Web Forensics and IoT Forensics, alongside enhanced coverage of malware forensics (including Emotet and EternalBlue), cloud forensics across AWS, Azure, and GCP, and RAM and Tor forensics.
Accredited under ISO/IEC 17024 (ANAB) and approved under U.S. DoD Directive 8140, CHFI carries formal government recognition as an intermediate-level qualification for three critical DFIR (Digital Forensics and Incident Response) work roles defined by the DoD Cyber Workforce Framework (DCWF). The certification is vendor-neutral in scope but technically deep, with more than 600 forensic tools covered across 68+ hands-on labs, making it one of the most lab-intensive digital forensics programs available.
CHFI is designed for cybersecurity and IT professionals who investigate, respond to, or prosecute cybercrime. Primary job roles include forensic computer analysts, cyber defense forensic analysts, malware analysts, incident responders, information security professionals, and IT auditors. It is also well-suited for law enforcement personnel, military and defense professionals, legal professionals who need to understand digital evidence, and banking or insurance professionals dealing with fraud investigations.
Candidates typically have a background in information technology or cybersecurity and are looking to specialize in digital forensics. The program is appropriate for both practitioners aiming to formalize existing skills and professionals transitioning into a DFIR-focused role. While there is no strict experience prerequisite if attending official training, those applying via the self-study eligibility path should have at least two years of information security experience.
There are no mandatory prerequisites for candidates who enroll in an official EC-Council authorized training program (via Training Partner, iLearn self-study, or iWeek live online). Attending the official CHFI course grants automatic eligibility to sit the exam upon completion.
Candidates who wish to challenge the exam without attending official training must submit an EC-Council Exam Eligibility Application, pay a non-refundable $100 eligibility fee, and demonstrate a minimum of two years of professional experience in the information security field. Practically, EC-Council recommends that candidates possess foundational knowledge of networking concepts, operating systems (Windows, Linux, macOS), cybersecurity fundamentals, and basic incident response procedures before undertaking CHFI study. Prior exposure to ethical hacking concepts (such as through CEH) is beneficial but not required.
The CHFI exam (312-49) consists of 150 multiple-choice questions and must be completed within 240 minutes (4 hours). The exam is delivered through EC-Council's ECC Exam Centers worldwide or via remote proctoring. The exam cost is $650 USD.
To maintain exam integrity, EC-Council administers the test in multiple forms with different question banks. Cut scores are set on a per-form basis, meaning the passing threshold can range from 60% to 85% depending on the specific form delivered. EC-Council publishes a 70% passing score as the benchmark figure. Scores are reported immediately upon completion at test centers. The certification is valid for three years, after which holders must earn 120 EC-Council Education Credits (ECE) to renew.
CHFI-certified professionals qualify for roles including Forensic Computer Analyst, Cyber Defense Forensic Analyst, Malware Analyst, Incident Responder, Cybercrime Investigator, and Information Systems Security Professional. The certification carries particular weight in government and defense sectors: under DoD Directive 8140 (the successor to DoD 8570), CHFI is formally recognized as an intermediate-level qualification for three DFIR-related DCWF work roles, making it a required or preferred credential for cybersecurity positions across U.S. federal agencies and defense contractors. The certification is also valued in finance, healthcare, legal, and insurance sectors where digital evidence and regulatory compliance intersect.
According to PayScale, CHFI-certified professionals earn an average salary of approximately $97,000, with ranges from $72,000 to $118,000 depending on role, location, and experience. Salary.com data places the average forensic analyst salary at $115,175 annually in the U.S. EC-Council reports that CHFI is the only forensics-focused certification program whose holders average a six-figure salary, according to its Salary Survey Report 75. Compared to alternatives such as GCFE (GIAC) or the AccessData ACE, CHFI's broader scope — spanning cloud, IoT, dark web, and mobile forensics — and its DoD recognition give it a stronger positioning for professionals targeting both private-sector and government DFIR roles.
5 sample questions with answers and explanations. The full bank has 589 questions, enough for 4 full-length practice exams.
Preview — answers shown1. During malware static analysis, you examine a suspicious PE file and notice the entry point is located outside the .text section, raw size equals zero while virtual size is greater than zero for multiple sections, and entropy measurements exceed 7.5. What do these indicators suggest? (Select one!)
Explanation
These are classic indicators of packed or encrypted malware. Entry point outside the .text section indicates custom unpacking code in another section. Raw size of zero with virtual size greater than zero indicates sections that will be unpacked or decrypted at runtime rather than stored on disk. Entropy exceeding 7.5 suggests encrypted or highly compressed data, as random data approaches maximum entropy of 8.0 while normal executable code typically has entropy between 5.0 and 6.5. Packers like UPX, ASPack, and custom packers create these patterns to evade antivirus detection and complicate analysis. Digitally signed legitimate software would have normal section characteristics and entropy values. Corrupted executables would show structural inconsistencies and fail to execute properly. Debug builds contain additional symbol information but maintain normal section layouts and entropy values.
2. A digital forensic investigator needs to acquire data from a passcode-locked iPhone X running iOS 15.3. The device owner is uncooperative and the passcode is unknown. The investigator has access to checkm8-based tools and can place the device into DFU mode. Which acquisition approach will yield the maximum amount of recoverable data given these constraints? (Select one!)
Explanation
BFU (Before First Unlock) extraction using checkm8 is the only viable option for a passcode-locked iPhone X on iOS 15 when the passcode is unknown. While the data recovered is limited to items with kSecAttrAccessibleAlways attributes, some authentication tokens, email credentials, and unencrypted files can be extracted. Full file system extraction via checkm8 requires the screen lock passcode to be removed first on iPhone X running iOS 14 or 15, which is impossible without cooperation. iTunes logical backup requires either the passcode or an existing trust pairing and provides no access to locked devices. AFC2 service requires jailbreak with device access and cannot be deployed on a locked device without the passcode.
3. An email forensics investigator examines message headers to determine authenticity. The Authentication-Results header shows: dkim=pass, spf=fail, dmarc=fail. What does this combination indicate? (Select one!)
Explanation
DKIM pass indicates the email's cryptographic signature is valid and the message was not altered in transit, but SPF fail means the sending server's IP address is not authorized by the sender's domain, and DMARC fail means the overall authentication policy failed due to the SPF failure. This pattern often indicates email spoofing where an attacker controlled the sending server to create valid DKIM signatures but could not spoof the authorized IP addresses. A legitimate email would show pass for all three mechanisms. Email encryption (S/MIME or PGP) does not prevent authentication header generation. Stripped headers would show no Authentication-Results header at all.
4. A forensic investigator needs to create a forensic image of a 2TB hard drive with simultaneous verification and wants to generate both MD5 and SHA256 hashes during acquisition while splitting the output into 10GB segments. The investigator also needs a detailed hash log for court presentation. Which command accomplishes all these requirements? (Select one!)
Explanation
The dcfldd command with hash=md5,sha256 hashlog=hash.log split=10G parameters performs on-the-fly dual hashing, creates a detailed hash log file, and automatically splits output into 10GB segments. The DoD Computer Forensics Lab DD (dcfldd) tool was specifically designed for forensic imaging with enhanced features over standard dd. Standard dd does not support built-in hashing or automatic file splitting. The dc3dd tool supports hashing but uses different syntax (hof for hash output file) and the example shown doesn't include splitting. The ewfacquire tool creates Expert Witness Format (E01) files with compression but uses different parameters and doesn't match the specified dcfldd syntax in the question requirements.
5. An investigator uses Sleuth Kit to analyze a disk image and runs 'istat -o 2048 image.dd 128-48-5' which returns detailed information. What does the number 128-48-5 represent? (Select one!)
Explanation
Sleuth Kit uses metadata addresses in the format MFT_ENTRY-SEQUENCE-ATTRIBUTE_ID for NTFS file systems. The first number (128) is the MFT entry number, the second (48) is the sequence number used to distinguish files that reused the same MFT slot across time, and the third (5) is the attribute ID within that MFT entry. The sequence number is critically important for preventing misattribution when the same MFT entry was reallocated to different files over time. This addressing scheme allows precise identification of specific file attributes even for deleted or reallocated entries. Partition offsets are specified with the -o parameter separately. Ext4 uses simpler inode numbers without this compound addressing. LBA coordinates do not use hyphenated notation.
