The answer is the `msgstore.db` database and the external media directory. This is correct because WhatsApp’s Android forensics relies on two key artefacts: the primary SQLite database at `/data/data/com.whatsapp/databases/msgstore.db` stores chat messages, and deleted entries are often only flagged for deletion rather than physically erased until a vacuum operation, making recovery possible. Additionally, media files like images and videos persist in `/data/media/0/Android/data/com.whatsapp/` even after the associated chat message is deleted, as the file itself is not automatically removed. On the CHFI exam, this question tests your understanding of Android file system hierarchy and SQLite data retention—a common trap is assuming deletion means permanent removal. Remember the mnemonic “DB for texts, Media for files” to link each artefact to its recoverable data type.
CHFI Mobile and Malware Forensics Practice Question
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.
During a mobile forensic investigation, an examiner wants to recover deleted WhatsApp messages from an Android device. Which of the following artefacts should the examiner examine? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
/data/media/0/Android/data/com.whatsapp/
Option A is correct because WhatsApp stores media files (images, videos, voice notes) in the external app-specific directory `/data/media/0/Android/data/com.whatsapp/`. Even after a message is deleted from the chat, the media file may remain in this directory if it was not explicitly removed, allowing recovery. Option C is correct because the primary SQLite database `msgstore.db` in `/data/data/com.whatsapp/databases/` contains the chat messages, including deleted entries that are often only marked as deleted but not physically removed until a vacuum operation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
/data/media/0/Android/data/com.whatsapp/
Why this is correct
This directory contains WhatsApp media and backup files that may include message history.
Related concept
Read the scenario before looking for a memorised answer.
This is the primary WhatsApp message database; deleted records may remain in unallocated space or WAL files.

✗
/data/data/com.whatsapp/files/Avatars/
Why it's wrong here
Contains profile pictures, not messages.
✗
/data/data/com.google.android.gms/databases/
Why it's wrong here
Contains Google Play Services data, not WhatsApp messages.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between the app-specific data directory (`/data/data/`) and the external media directory (`/data/media/0/`), tricking candidates into thinking only the internal database holds deleted messages, while media files in the external directory are also recoverable artefacts.
Detailed technical explanation
How to think about this question
WhatsApp uses a WAL (Write-Ahead Log) journaling mode for its SQLite databases, meaning deleted rows in `msgstore.db` may still be present in the WAL file (`msgstore.db-wal`) until a checkpoint occurs. In real-world forensics, examiners should also check the `msgstore.db.crypt*` backup files (e.g., `msgstore.db.crypt12`) in `/data/media/0/WhatsApp/Databases/` for older message versions. The `/data/media/0/Android/data/com.whatsapp/` directory is accessible without root on Android 10 and below, but on Android 11+ scoped storage restricts direct access, requiring a physical acquisition or backup.

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.

What is the correct answer to this question?
The correct answer is: /data/media/0/Android/data/com.whatsapp/ — Option A is correct because WhatsApp stores media files (images, videos, voice notes) in the external app-specific directory `/data/media/0/Android/data/com.whatsapp/`. Even after a message is deleted from the chat, the media file may remain in this directory if it was not explicitly removed, allowing recovery.
