Introduction
Meta Platforms operates two of the world’s most widely used communication platforms: Facebook and Facebook Messenger. Together, these services allow users to communicate through text messages, voice calls, video calls, image sharing, file transfers, and social networking activities.
Due to their widespread adoption, Facebook and Messenger frequently feature in digital forensic investigations involving criminal, civil, corporate, and family court matters.
Digital forensic examiners often analyse Facebook-related data to establish communication timelines, identify users, recover deleted content, verify relationships, and investigate online activity.
History of Facebook
Facebook was launched in February 2004 by Mark Zuckerberg and fellow students at Harvard University. Initially known as “TheFacebook,” the platform was designed as a social networking site for university students.
Key milestones include:
- 2004 – Facebook launches for Harvard students.
- 2005 – Expanded to other universities and schools.
- 2006 – Opened registration to anyone aged 13 and over.
- 2007 – Introduction of Facebook Pages for businesses and organisations.

- 2021 – Facebook’s parent company rebrands as Meta.
Today, Facebook remains one of the largest social networking platforms globally, supporting billions of users.
History of Facebook Messenger
Facebook Messenger originated as Facebook Chat, an integrated messaging feature within Facebook’s website.
Significant developments include:
- 2008 – Facebook Chat introduced.
- 2011 – Messenger released as a standalone mobile application.
- 2013 – Introduction of voice calling.
- 2015 – Video calling functionality added.
- 2016 – Integration of chatbots and business messaging.
- 2020 onwards – Enhanced end-to-end encryption and cross-platform messaging features.
Messenger has evolved into a comprehensive communication platform supporting individual and group conversations, media sharing, and real-time communications.
Importance in Digital Forensics
Facebook and Messenger often contain valuable digital evidence that can assist investigations by providing:
- Communication records
- Relationship mapping
- Location information
- Photographs and videos
- Business communications
- Timeline reconstruction
- Evidence of intent, knowledge, or state of mind
Forensic investigators may examine data from mobile devices, computers, cloud backups, and legal disclosures obtained from Meta.
Facebook Forensic Artefacts
Account Information
Facebook applications may store:
- User IDs
- Names and profile details
- Email addresses
- Phone numbers
- Account settings
- Authentication tokens
These artefacts can help attribute device usage to a particular user.
Social Activity
Investigators may recover:
- Posts and comments

- Search history
This information can establish user behaviour and associations.
Location Data
Depending on permissions and settings, Facebook may record:
- Check-ins
- Tagged locations
- IP address history
- Approximate login locations
Location artefacts can assist in placing a user at or near a specific location.
Media Artefacts
Forensic examinations frequently identify:
- Uploaded photographs
- Videos
- Profile images
- Shared media
- Metadata associated with images
Metadata may include timestamps and location information.
Facebook Messenger Forensic Artefacts
Message Content
Messenger data can contain:
- One-to-one conversations
- Group chats
- Deleted messages (in some circumstances)
- Draft messages
- Reactions and replies
Message content often forms a key source of evidence.
Attachments
Messenger may store references to:
- Images
- Videos
- Voice messages
- Documents
- Shared links
Associated metadata may identify when files were sent or received.
Call Records
Messenger can maintain evidence relating to:
- Voice calls
- Video calls
- Call participants

These records may corroborate communication between parties.
Contact Information
Artefacts may include:
- Contact identifiers
- User IDs
- Display names
- Group membership information
Such information assists in identifying communication participants.
Common Mobile Device Artefacts
During examinations of Android and iOS devices.
Android
Typical locations may include:
- Messenger application databases
- Cache files
- Media storage directories
- Notification databases
- Application preferences
Common database formats include SQLite databases containing message and account information.
iOS
Potential artefacts include:
- Application sandbox data
- Cached media files
- Account configuration files
- Notification records
- Shared application containers
Forensic tools may extract these artefacts from logical, filesystem, or full file system acquisitions.
Cloud and Server-Side Evidence
Where legally authorised, investigators may obtain information directly from Meta, including:
- Account subscriber details
- Login records
- IP addresses
- Messenger communications
- Friends and contacts information
- Uploaded content
The availability of data depends on legal authority, jurisdiction, retention policies, and privacy protections.
Conclusion
Facebook and Facebook Messenger are significant sources of digital evidence in modern investigations.
Their extensive communication, social networking, media sharing, and location-based features generate a wide range of forensic artefacts.
Digital forensic examiners can use these artefacts to reconstruct events, identify users, establish communication patterns, and provide evidence for criminal, civil, corporate, and family court proceedings.
Understanding the history, functionality, and forensic footprint of Facebook and Messenger is therefore essential for any digital forensic investigation involving social media evidence.
