Welcome back, aspiring digital investigators!

Today we will take a look at WhatsApp forensics. WhatsApp is one of those apps that are both private and routine for many users. People treat chats like a private conversation, and because it feels comfortable, users often share things there that they would not say on public social networks. That’s why WhatsApp is so critical for digital forensics. The app stores conversations, media, timestamps, group membership information and metadata that can help reconstruct events, identify contacts and corroborate timelines in criminal and cyber investigations.

At Hackers-Arise we offer professional digital forensics services that support cybercrime investigations and fraud examinations. WhatsApp forensics is done to find reliable evidence. The data recovered from a device can show who communicated with whom, when messages were sent and received, what media was exchanged, and often which account owned the device. That information is used to link suspects and verify statements. It also maps movements when combined with location artifacts that investigators and prosecutors can trust.

You will see how WhatsApp keeps its data on different platforms and what those files contain.

WhatsApp Artifacts on Android Devices

On Android, WhatsApp stores most of its private application data inside the device’s user data area. In a typical layout you will find the app’s files under a path such as /data/data/com.whatsapp/ (or equivalently /data/user/0/com.whatsapp/ on many devices). Those directories are not normally accessible without elevated privileges. To read them directly you will usually need superuser (root) access on the device or a physical dump of the file system obtained through lawful and technically appropriate means. If you do not have root or a physical image, your options are restricted to logical backups or other extraction methods which may not expose the private WhatsApp databases.

Two files deserve immediate attention on Android: wa.db and msgstore.db. Both are SQLite databases and together they form the core of WhatsApp evidence.

wa.db is the contacts database. It lists the WhatsApp user’s contacts and typically contains phone numbers, display names, status strings, timestamps for when contacts were created or changed, and other registration metadata. You will usually open the file with a SQLite browser or query it with sqlite3 to inspect tables. The key tables investigators look for are the table that stores contact records (often named wa_contacts or similar), sqlite_sequence which holds auto-increment counts and gives you a sense of scale, and android_metadata which contains localization info such as the app language.

Wa.db is essentially the address book for WhatsApp. It has names, numbers and a little context for each contact.

msgstore.db is the message store. This database contains sent and received messages, timestamps, message status, sender and receiver identifiers, and references to media files. In many WhatsApp versions you will find tables that include a general information table (often named sqlite_sequence), a full-text index table for message content (message_fts_content or similar), the main messages table which usually contains the message body and metadata, messages_thumbnails which catalogs images and their timestamps, and a chat_list table that stores conversation entries. 

Be aware that WhatsApp evolves and field names change between versions. Newer schema versions may include extra fields such as media_enc_hash, edit_version, or payment_transaction_id. Always inspect the schema before you rely on a specific field name.

On many Android devices WhatsApp also keeps encrypted backups in a public storage location, typically under /data/media/0/WhatsApp/Databases/ (the virtual SD card)

or /mnt/sdcard/WhatsApp/Databases/ for physical SD cards. Those backup files look like msgstore.db.cryptXX, where XX indicates the cryptographic scheme version. 

The msgstore.db.cryptXX files are an encrypted copy of msgstore.db intended for device backups. To decrypt them you need a cryptographic key that WhatsApp stores privately on the device, usually somewhere like /data/data/com.whatsapp/files/. Without that key, those encrypted backups are not readable.

Other important Android files and directories to examine include the preferences and registration XMLs in /data/data/com.whatsapp/shared_prefs/. The file com.whatsapp_preferences.xml often contains profile details and configuration values. A fragment of such a file may show the phone number associated with the account, the app version, a profile message such as “Hey there! I am using WhatsApp.” and the account display name. The registration.RegisterPhone.xml file typically contains registration metadata like the phone number and regional format. 

The axolotl.db file in /data/data/com.whatsapp/databases/ holds cryptographic keys (used in the Signal/Double Ratchet protocol implementation) and account identification data. chatsettings.db contains app settings. Logs are kept under /data/data/com.whatsapp/files/Logs/ and may include whatsapp.log as well as compressed rotated backups like whatsapp-YYYY-MM-DD.1.log.gz

These logs can reveal app activity and errors that may be useful for timing or troubleshooting analysis.

Media is often stored in the media tree on internal or external storage:

/data/media/0/WhatsApp/Media/WhatsApp Images/ for images,

/data/media/0/WhatsApp/Media/WhatsApp Voice Notes/ for voice messages (usually Opus format), WhatsApp Audio, WhatsApp Video, and WhatsApp Profile Photos.

Within the app’s private area you may also find cached profile pictures under /data/data/com.whatsapp/cache/Profile Pictures/ and avatar thumbnails under /data/data/com.whatsapp/files/Avatars/. Some avatar thumbnails use a .j extension while actually being JPEG files. Always validate file signatures rather than trusting extensions.

If the device uses an SD card, a WhatsApp directory at the card’s root may store copies of shared files (/mnt/sdcard/WhatsApp/.Share/), a trash folder for deleted content (/mnt/sdcard/WhatsApp/.trash/), and the Databases subdirectory with encrypted backups and media subfolders mirroring those on internal storage. The presence of deleted files or .trash folders can be a fruitful source of recovered media.

A key complication on Android is manufacturer or custom-ROM behavior. Some vendors add features that change where app data is stored. For example, certain Xiaomi phones implement a “Second Space” feature that creates a second user workspace. WhatsApp in the second workspace stores its data under a different user ID path such as /data/user/10/com.whatsapp/databases/wa.db rather than the usual /data/user/0/com.whatsapp/databases/wa.db

As things evolve and change, you need to validate the actual paths on the target device rather than assuming standard locations.

WhatsApp Artifacts on iOS Devices

On iOS, WhatsApp tends to centralize its data into a few places and is commonly accessible via device backups. The main application database is often ChatStorage.sqlite located under a shared group container such as /private/var/mobile/Applications/group.net.whatsapp.WhatsApp.shared/ (some forensic tools display this as AppDomainGroup-group.net.whatsapp.WhatsApp.shared).

Within ChatStorage.sqlite the most informative tables are often ZWAMESSAGE, which stores message records, and ZWAMEDIAITEM, which stores metadata for attachments and media items. Other tables like ZWAPROFILEPUSHNAME and ZWAPROFILEPICTUREITEM map WhatsApp identifiers to display names and avatars. The table Z_PRIMARYKEY typically contains general database metadata such as record counts.

iOS also places supporting files in the group container. BackedUpKeyValue.sqlite can contain cryptographic keys and data useful for identifying account ownership. ContactsV2.sqlite stores contact details: names, phone numbers, profile statuses and WhatsApp IDs. A simple text file like consumer_version may hold the app version and current_wallpaper.jpg (or wallpaper in older versions) contains the background image used in WhatsApp chats. The blockedcontacts.dat file lists blocked numbers, and pw.dat can hold an encrypted password. Preference plists such as net.whatsapp.WhatsApp.plist or group.net.whatsapp.WhatsApp.shared.plist store profile settings.

Media thumbnails, avatars and message media are stored under paths like /private/var/mobile/Applications/group.net.whatsapp.WhatsApp.shared/Media/Profile/ and /private/var/mobile/Applications/group.net.whatsapp.WhatsApp.shared/Message/Media/. WhatsApp logs, for example calls.log and calls.backup.log, often survive in the Documents or Library/Logs folders and can help establish call activity.

Because iOS devices are frequently backed up through iTunes or Finder, you can often extract WhatsApp artefacts from a device backup rather than needing a full file system image. If the backup is unencrypted and complete, it may include the ChatStorage.sqlite file and associated media. If the backup is encrypted you will need the backup password or legal access methods to decrypt it. In practice, many investigators create a forensic backup and then examine the WhatsApp databases with a SQLite viewer or a specialized forensic tool that understands WhatsApp schema differences across versions.

Practical Notes For Beginners

From the databases and media files described above you can recover contact lists, full or partial chat histories, timestamps in epoch format (commonly Unix epoch in milliseconds on Android), message status (sent, delivered, read), media filenames and hashes, group membership, profile names and avatars, blocked contacts, and even application logs and version metadata. It helps us understand who communicated with whom, when messages were exchanged, whether media were transferred, and which accounts were configured on the device.

For beginners, a few practical cautions are important to keep in mind. First, always operate on forensic images or copies of extracted files. Do not work directly on the live device unless you are performing an approved, controlled acquisition and you have documented every action. Second, use reliable forensic tools to open SQLite databases. If you are parsing fields manually, confirm timestamp formats and time zones. Third, encrypted backups require the device’s key to decrypt. The key is usually stored in the private application area on Android, and without it you cannot decode the .cryptXX files. Fourth, deleted chats and files are not always gone, as databases may leave records or media may remain in caches or on external storage. Yet recovery is never guaranteed and depends on many factors including the time since deletion and subsequent device activity.

When you review message tables, map the message ID fields to media references carefully. Many WhatsApp versions use separate tables for media items where the actual file is referenced by a media ID or filename. Thumbnail tables and media directories will help you reconstruct the link between a textual message and the file that accompanied it. Pay attention to the presence of additional fields in newer app versions. These may contain payment IDs, edit history or encryption metadata. Adapt your queries accordingly.

Finally, because WhatsApp and operating systems change over time, always inspect the schema and file timestamps on the specific evidence you have. Do not assume field names or paths are identical between devices or app versions. Keep a list of the paths and filenames you find so you can reproduce your process and explain it in reports.

Summary

WhatsApp forensics is a rich discipline. On Android the primary artifacts are the wa.db contacts database, the msgstore.db message store and encrypted backups such as msgstore.db.cryptXX, together with media directories, preference XMLs and cryptographic key material in the app private area. On iOS the main artifact is ChatStorage.sqlite and a few supporting files in the app group container and possibly contained in a device backup. To retrieve and interpret these artifacts you must have appropriate access to the device or an image and know where to look for the app files on the device you are examining. Also, be comfortable inspecting SQLite databases and be prepared to decrypt backups where necessary.

Welcome back, dear digital investigators! 

Today, we’re exploring mobile forensics, a field that matters deeply in modern crime investigations. Think about how much our phones know about us. They carry our contacts, messages, locations, and app history in many ways. They are a living log of our daily lives. Because they travel with us everywhere, they can be a goldmine of evidence when something serious happens, like a crime. In a murder investigation, for instance, a suspect’s or a victim’s phone can help us answer critical questions: Who were they in touch with right before the crime? Where did they go? What were they doing? What kind of money dealings were they involved in? All of this makes mobile forensics powerful for investigators. As digital forensic specialists, we use that data to reconstruct timelines, detect motives, and understand relationships. Because of this, even a seemingly small app on a phone might have huge significance. For example, financial trading apps may reveal risky behavior or debt. Chat apps might contain confessions or threats. Location logs might show the victim visiting unusual places.

The Difference Between Android and iOS Forensics

When we do mobile forensics, we usually see Android and iOS devices. These two operating systems are quite different under the hood, and that affects how we work with them. On Android, there’s generally more openness. The file system for many devices is more accessible, letting us examine data stored in app directories, caches, logs, and more. Because Android is so widespread and also fragmented with many manufacturers and versions, the data we can access depends a lot on the model and version. 

On iOS, things are tighter. Apple uses its own file system (APFS), and there’s strong encryption, often backed by secure hardware. That means extracting data can be more challenging. Because of this, forensic tools must be very sophisticated to handle iOS devices.

When it comes to which has more usable data, Android often gives us more raw artifacts because of its flexibility. But iOS can also be very rich, especially when data is backed up to iCloud or when we can legally access the device in powerful ways.

The Tools For the Job

One of the most powerful tools is Cellebrite, which is used by law enforcement and digital forensic labs. Cellebrite’s tools are capable of extracting data from both Android and iOS devices, sometimes even from locked devices. But the ability to extract depends a lot on the device model, its security patch level, and how encrypted it is.

There’s an interesting twist when it comes to GrapheneOS, which is a very security-focused version of Android. According to reports, Cellebrite tools struggle more with GrapheneOS, especially on devices updated after 2022. In some cases, they may be able to do a “consent-based” extraction (meaning the phone has to be unlocked by the user), but they can’t fully bypass the security on a fully patched GrapheneOS phone. Because of that, from a security perspective, users are strongly encouraged to keep their firmware and operating system updated. Regular updates close vulnerabilities. Also, using strong passcodes, enabling encryption, and being careful about where sensitive data is stored can make a real difference in protecting personal data.

Our Case: Investigating a Murder Using an Android Phone

Now, let’s turn to our case. We are in the middle of a murder investigation, and we’ve managed to secure the victim’s Android phone. After talking with witnesses and people who were close to the victim, we believe this phone holds critical evidence. To analyze all of that, we are using ALEAPP, a forensic tool made specifically for parsing Android data.

ALEAPP and How It Works

ALEAPP stands for Android Logs, Events, And Protobuf Parser. It’s an open-source tool maintained by the forensic community. Basically, ALEAPP allows us to take the extracted data from an Android phone, whether it’s a logical extraction, a TAR or ZIP file, or a file-system dump and turn that raw data into a human-readable, well-organized report. ALEAPP can run through a graphical interface, which is very friendly and visual, or via command line, depending on how you prefer to work. As it processes data, it goes through different modules for things like call logs, SMS, app usage, accounts, Wi-Fi events, and more. In the end, it outputs a report, so you can easily explore and navigate all the findings.

You can find the repository here:

https://github.com/abrignoni/ALEAPP

What We Found on the Victim’s Phone

We started by examining the internal storage of the Android device, especially the /data folder. This is where apps keep their private data, caches, and account information. Then, we prepared a separate place on our investigation workstation, a folder called output, where ALEAPP would save its processed data.

Once ALEAPP was ready, we launched it and pointed it to the extracted directories. We left all its parsing modules turned on so we wouldn’t miss any important artifact. We clicked “Process,” and depending on the size of the extracted data, we waited for a few minutes while ALEAPP parsed everything.

When the processing was done, a new folder appeared inside our output directory. In that folder, there was a file called index.html, that’s our main report. We opened it with a browser and the GUI showed us different categories. The interface is clean and intuitive, so even someone not deeply familiar with command-line tools can navigate it.

Evidence That Stood Out

One of the first things that caught our attention was a trading app. ALEAPP showed an installed application named OlympTrade. A quick web search confirmed that OlympTrade is a real online trading platform. That fits with what witnesses told us. The victim was involved in trading, possibly borrowing or investing money. We also noted a hash value for the app in our report, which helps prove the data’s integrity. This means we can be more confident that what we saw hasn’t been tampered with.

Next, we turned to text messages. According to the victim’s best friend’s testimony, the victim avoided some calls and said he owed a lot of money. When we checked SMS data in ALEAPP, we found a thread where the victim indeed owed $25,000 USD to someone.

We looked up the number in the contacts list, and it was saved under the name John Oberlander. That makes John an important person of interest in this investigation.

Then, we dove into location data. The victim’s family said that on September 20, 2023, he left his home without saying where he was going. In ALEAPP’s “Recent Activity” section, which tracks events like Wi-Fi connections, GPS logs, and other background activity, we saw evidence placing him at The Nile Ritz-Carlton in Cairo, Egypt. This is significant. A 5-star hotel, which could have security footage, check-in records, or payment logs. Investigators would almost certainly reach out to the hotel to reconstruct his stay.

The detective pressed on with his investigation and spoke with the hotel staff, hoping to fill in more of the victim’s final days. The employees confirmed that the victim had booked a room for ten days and was supposed to take a flight afterward. Naturally, the investigator wondered whether the victim had saved any ticket information on the phone, since many people store their travel plans digitally nowadays. Even though no tickets turned up in the phone’s files, the search did reveal something entirely different, and potentially much more important. We looked at Discord, since the app appeared in the list of installed applications. Discord logs can reveal private chats, plans, and sometimes illicit behavior. In this case, we saw a conversation indicating that the victim changed his travel plans. He postponed a flight to October 1st, according to the chat.

Later, he agreed to meet someone in person at a very specific place. It was the Fountains of Bellagio in Las Vegas. That detail could tie into motive or meetings related to the crime.

What Happens Next

At this stage, we’ve collected and parsed digital evidence, but our work is far from over. Now, we need to connect the phone-based data to the real world. That means requesting more information from visited places, checking for possible boarding or ticket purchases, and interviewing people named in the phone, like John Oberlander, or the person from Discord.

We might also want to validate financial trail through the trading platform (if we can access it legally), bank statements, or payment records. And importantly, we should search for other devices or backups. Maybe the victim had cloud backups, like Google Drive, or other devices that shed more light.

Reconstructed Timeline

The victim was heavily involved in trading and apparently owed $25,000 USD to John Oberlander. On September 20, 2023, he left his residence without telling anyone where he was headed. The phone’s location data places him later that day at The Nile Ritz-Carlton in Cairo, suggesting he stayed there. Sometime afterward, according to Discord chats, he changed his travel plans and his flight was rescheduled for October 1. During these chats, he arranged a meeting with someone at the Fountains of Bellagio in Las Vegas.

Summary

Mobile forensics is a deeply powerful tool when investigating crimes. A single smartphone can hold evidence that helps reconstruct what happened, when, and with whom. Android devices often offer more raw data because of their openness, while iOS devices pose different challenges due to their strong encryption. Tools like ALEAPP let us parse all of that data into meaningful and structured reports.

In the case we’re studying, the victim’s phone has offered us insights into his financial troubles, his social connections, his movements, and his plans. But digital evidence is only one piece. To solve a crime, we must combine what we learn from devices with interviews, external records, and careful collaboration with other investigators.

Our team provides professional mobile forensics services designed to support individuals, organizations, and legal professionals who need clear, reliable answers grounded in technical expertise. We also offer a comprehensive digital forensics course for those who want to build their own investigative skills and understand how evidence is recovered, analyzed, and preserved.

Welcome, aspiring forensic investigators!

Welcome to the new Digital Forensics module. In this guide we introduce digital forensics, outline the main phases of a forensic investigation, and survey a large set of tools you’ll commonly meet. Think of this as a practical map: the article briefly covers the process and analysis stages and points to tools you can use depending on your objectives. Later in the course we’ll dig deeper into Windows and Linux artifacts and show how to apply the most common tools to real cases.

Digital forensics is growing fast because cyber incidents are happening every day. Budget limits, legacy systems, and weak segmentation leave many organizations exposed. AI and automation make attacks easier and fasterю. Human mistakes, especially successful phishing, remain a top cause of breaches. When prevention fails, digital forensics helps answer what happened, how it happened, and what to do next. It’s a mix of technical skills, careful procedure, and clear reporting.

What is Digital Forensics?

Digital forensics (also called computer forensics or cyber forensics) is the discipline of collecting, preserving, analyzing, and presenting digital evidence from computers, servers, mobile devices, networks, and storage media. It grew from early law-enforcement needs in the 1980s into a mature field in the 1990s and beyond, as cybercrime increased and investigators developed repeatable methods.

Digital forensics supports incident response, fraud investigations, data recovery, and threat hunting. The goals are to reconstruct timelines, identify malicious activity, measure impact, and produce evidence suitable for legal, regulatory, or incident-response use.

Main Fields Inside Digital Forensics

Digital forensics branches into several focused areas. Each requires different tools and approaches.

Computer forensics

Focuses on artifacts from a single machine: RAM, disk images, the Windows registry, system logs, file metadata, deleted files, and local application data. The aim is to recreate what a user or a piece of malware did on that host.

Network forensics

Covers packet captures, flow records, and logs from routers, firewalls and proxies. Analysts use network data to trace communications, find command-and-control channels, spot data exfiltration, and follow attacker movement across infrastructure.

Forensic data analysis

Deals with parsing and interpreting files, database contents, and binary data left after an intrusion. It includes reverse engineering malware fragments, reconstructing corrupted files, and extracting meaningful information from raw or partially damaged data.

Mobile device forensics

Targets smartphones and tablets. Android and iOS store data differently from desktops, so investigators use specialized methods to extract messages, app data, calling records, and geolocation artifacts.

Hardware forensics

The most specialized area: low-level analysis of firmware, microcontrollers, and embedded devices. This work may involve extracting firmware from chips, analyzing device internals, or studying custom hardware behavior (for example, the firmware of an IoT transmitter or a skimmer installed on an ATM).

Methods and approaches

Digital forensics work generally falls into two modes: static (offline) analysis and live (in-place) analysis. Both are valid. The choice depends on goals and constraints.

Static analysis

The traditional workflow. Investigators take the device offline, build a bit-for-bit forensic image, and analyze copies in a lab. Static analysis is ideal for deep disk work: carving deleted files, examining file system metadata, and creating a defensible chain of custody for evidence.

Live analysis

Used when volatile data matters or when the system cannot be taken offline. Live techniques capture RAM contents, running processes, open network connections, and credentials kept in memory. Live collection gives access to transient artifacts that vanish on reboot, but it requires careful documentation to avoid altering evidence.

Live vs Static

Static work preserves the exact state of disk data and is easier to reproduce. Live work captures volatile evidence that static imaging cannot. Modern incidents often need both. They start with live capture to preserve RAM and active state, then create static images for deeper analysis.

The forensic process

1. Create a forensic image

Make a bit-for-bit copy of storage or memory. Work on the copy. Never change the original.

2. Document the system’s state

Record running processes, network connections, logged-in users, system time, and any other volatile details before power-down.

3. Identify and preserve evidence

Locate files, logs, configurations, memory dumps, and external devices. Preserve them with hashes and a clear chain of custody.

4. Analyze the evidence

Use appropriate tools to inspect logs, binaries, file systems, and memory. Look for malware artifacts, unauthorized accounts, and modified system components.

5. Timeline analysis

Correlate timestamps across artifacts to reconstruct the sequence of events and show how an incident unfolded.

6. Identify indicators of compromise (IOCs)

Extract file hashes, IP addresses, domains, registry keys, and behavioral signatures that indicate malicious activity.

7. Report and document

Produce a clear, well-documented report describing methods, findings, conclusions, and recommended next steps.

Practical notes and best practices

a) Preserve original evidence. Always work with verified copies and record cryptographic hashes.

b) Capture volatile data early. RAM and live state can vanish on reboot. Prioritize their collection when necessary.

c) Keep clear records. Document every action, including tools and versions, timestamps, and the chain of custody.

d) Match tools to goals. Use lightweight tools for quick triage and more powerful suites for deep dives.

e) Plan for scalability. Network forensics can generate huge data sets. Prepare storage and filtering strategies ahead of time.

Summary

We introduced digital forensics and laid out the main concepts you’ll need to start practical work: the different forensic disciplines, the distinction between live and static analysis, a concise process checklist, and a broad toolset organized by purpose. Digital forensics sits at the intersection of incident response, threat intelligence, and legal evidence collection. The methods and tools presented here form a foundation. In later lessons we’ll work through hands-on examples for Windows and Linux artifacts, demonstrate key tools in action, and show how to build timelines and extract actionable IOCs. 

Keep in mind that good forensic work is disciplined, repeatable, and well documented. That’s what makes the evidence useful and the investigation reliable.

If you need forensic assistance, we offer professional services to help investigate and mitigate incidents. Additionally, we provide classes on digital forensics for those looking to expand their skills and understanding in this field.
