Reinforce CHFI concepts with active-recall study cards covering all 13 blueprint domains. Each card shows the question on the front and the correct answer with a full explanation on the back.
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For CHFI preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the CHFI question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your CHFI flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real CHFI exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass CHFI.
Sample cards from the CHFI flashcard bank. Read the question, think of the answer, then read the explanation below.
During a forensic investigation, an analyst discovers that the suspect's hard drive was encrypted using BitLocker. The analyst has obtained the recovery key. Which of the following is the best next step to ensure data integrity?
Create a forensic image of the encrypted drive, then decrypt the image.
Creating a forensic image of the encrypted drive before decryption preserves the original evidence in its pristine, unaltered state. Decrypting the image later using the recovery key ensures that the original encrypted data remains intact and verifiable, maintaining data integrity throughout the investigation.
A first responder arrives at a crime scene where a computer is running. According to standard forensic procedure, what should the responder do FIRST?
Photograph the scene and secure the area
The first priority at a live crime scene is to preserve the integrity of the scene and all potential evidence. Standard forensic procedure (e.g., from NIST SP 800-86 and ACPO guidelines) mandates that the first responder must photograph the scene to document the state of the computer (including screen contents, cables, and peripherals) and secure the area to prevent unauthorized access or tampering. Only after this documentation and scene stabilization can the responder proceed to handle the live system, such as capturing volatile data or creating a forensic image.
A security analyst reviews an Apache access log entry: 192.168.1.5 - - [10/Jan/2024:08:12:35 +0000] "GET /index.php?id=1 UNION SELECT username,password FROM users-- HTTP/1.1" 200 4321 "-" "Mozilla/5.0". What type of attack is MOST likely indicated?
SQL injection
The log entry shows a UNION SELECT statement appended to the id parameter, which is a classic SQL injection attempt.
A security analyst is reviewing output from a Cuckoo Sandbox analysis of a suspicious executable. The report shows that the process created a mutex named 'Global\GLOBAL_MUTEX_123' and modified the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run\. Which behavioral indicator is MOST evident?
Persistence mechanism
The modification of the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run is a classic persistence mechanism. This key is automatically processed by Windows Explorer at user logon, causing any executable listed there to run. Combined with the mutex creation (which prevents multiple instances), the behavioral indicator is clearly an attempt to establish persistence on the host.
An investigator needs to capture network traffic from a live network segment without altering the traffic flow. Which technique should they use?
Configure a SPAN port on the switch
A SPAN (Switched Port Analyzer) port, also known as a mirror port, copies all traffic from a specified source port or VLAN to a destination port where the forensic workstation is connected. This allows the investigator to capture traffic without injecting any frames or altering the forwarding behavior of the switch, thus preserving the integrity of the live network segment.
An analyst recovers a hard drive from a suspect's computer. The drive has a partition table that uses a 32-bit identifier and a maximum partition size of 2 TB. Which partition table type is present?
MBR
The Master Boot Record (MBR) partition table uses a 32-bit identifier for partition entries and, with traditional 512-byte sectors, supports a maximum partition size of 2 TB. This matches the description exactly, making MBR the correct answer.
An organization uses Microsoft SQL Server 2019 with full recovery model. A database administrator accidentally executed a DROP TABLE statement. The transaction log was backed up immediately after the incident. Which forensic technique would allow the analyst to restore the dropped table?
Perform a tail-log backup, then restore the full backup and all subsequent transaction log backups, stopping before the DROP TABLE.
Under the full recovery model, point-in-time recovery is required to undo the DROP TABLE. By performing a tail-log backup (to capture any transactions after the last log backup), then restoring the full backup and all subsequent transaction log backups with STOPAT or STOPBEFOREMARK to the moment just before the DROP TABLE, the analyst can recover the table without losing other transactions. This is the only method that preserves the dropped table's data while maintaining database consistency.
An analyst receives an alert indicating a suspicious process (PID 3342) is making outbound connections on port 443 to an unknown IP. The system is a Windows 10 workstation. Which first responder action is MOST appropriate?
Capture a full memory dump using a tool like FTK Imager (Memory Capture) or DumpIt.
Capturing a full memory dump (option A) is the most appropriate first responder action because it preserves the volatile state of the suspicious process (PID 3342) and its associated artifacts (e.g., network connections, loaded DLLs, encryption keys) before any further system changes occur. This allows forensic analysis to identify the malware's behavior, such as command-and-control (C2) communication over port 443 (HTTPS), without altering evidence. Tools like FTK Imager (Memory Capture) or DumpIt acquire a raw .mem file that can be analyzed with Volatility or Rekall to extract process details, network sockets, and injected code.
A forensic lab is designing a network architecture to ensure the integrity of evidence during acquisition. What is the most critical design consideration?
Implement hardware write-blockers on all acquisition stations
Hardware write-blockers are the most critical design consideration because they physically prevent any write operations to the source drive at the ATA/SCSI command level, ensuring that the evidence remains bit-for-bit unchanged during acquisition. Without a hardware write-blocker, even a single read operation from a forensic workstation could inadvertently modify metadata (e.g., last access timestamps) or trigger anti-forensic mechanisms, compromising the integrity of the evidence and its admissibility in court.
A security analyst investigates a Windows system and finds an event with ID 4625 in the Security log. What does this event indicate?
A failed logon attempt
Event ID 4625 in the Windows Security log specifically indicates a failed logon attempt. This event is generated by the Local Security Authority Subsystem Service (LSASS) whenever an authentication attempt fails, regardless of the logon type (interactive, network, service, etc.). The event details include the account name, source IP address, and failure reason code (e.g., 0xC000006D for bad username/password).
An organization suspects a stealthy malware infection on a critical server. Traditional antivirus and EDR solutions have not detected anything. Which forensic approach would be most effective in identifying the malware, given that it likely resides only in memory?
Acquire a memory dump and perform memory forensics with tools like Volatility
The malware resides only in memory, making it invisible to disk-based scans. Memory forensics with tools like Volatility allows investigators to analyze RAM artifacts (e.g., processes, network connections, injected code) to detect stealthy malware that never writes to disk.
You are imaging a suspect's hard drive using a write blocker and dd command. After imaging, you verify the hash of the original drive and the image file. The original drive hash is SHA1: A1B2C3D4E5..., and the image hash is SHA1: F6G7H8I9J0... What is the most likely cause of the mismatch?
The write blocker malfunctioned and allowed writes to the original drive
The hash mismatch indicates that the data on the original drive and the image file are not identical. A write blocker malfunction that allowed writes to the original drive during the imaging process would alter the source data after the initial hash was computed, causing the final hash of the original drive to differ from the hash of the image file taken at a different point in time. This is the most direct cause of a hash mismatch because the write blocker's primary purpose is to prevent any modification to the evidence.
During a forensic investigation, an analyst needs to preserve the integrity of evidence on a hard drive. Which of the following is the best practice for acquiring an image of the drive?
Use a hardware write blocker and create a bit-stream image.
Using a hardware write blocker ensures that no write commands from the forensic workstation reach the suspect drive, preserving its integrity at the physical level. Creating a bit-stream image (sector-by-sector copy) captures all data, including slack space and unallocated clusters, which is essential for thorough forensic analysis. This combination is the gold standard in digital forensics, as mandated by best practices like those from NIST and the ACPO principles.

Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that CHFI questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.CHFI questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective CHFI study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
