Conversation records
Available one-to-one and group messages, replies, reactions, edits, unsent messages and service events reconstructed in context.
Facebook and Meta messaging evidence
Messenger
Forensics.
Forensic examination of Facebook Messenger chats, calls, shared media, account identifiers and associated Meta and device artefacts.
Discuss a deviceExamination
What we can
establish.
Every instruction begins with the questions to be answered. Available evidence depends on the device, software, state, credentials, backups and prior handling.
Calls & attachments
Call artefacts, photographs, video, audio, files, links and cached media examined with available metadata.
Account identity
Facebook identifiers, profiles, aliases, contact relationships and account changes assessed without treating a display name as proof of authorship.
Cross-device activity
Available browser, application, notification and connected-session artefacts considered across phones, tablets and computers.
Downloads & account data
Lawfully obtained account exports and available Meta records compared with local device material where appropriate.
Authenticity assessment
Screenshots and exports tested against underlying databases, identifiers, timestamps, attachments and surrounding activity.
Evidence source map
Beyond the
visible application.
Absence from one screen or device does not resolve the evidential question. Relevant records may be distributed across several sources.
Local records
Accessible chats, media, identifiers and account/session traces.
Backup and account
Account exports and configured encrypted message storage may require separate recovery material.
Existing linked endpoints
Existing browser/client records only where retained and accessible.
Limits and corroboration
An account export is not necessarily complete conversation history; encrypted storage configuration matters. Lawfully obtained counterpart records may corroborate the source.
Evidential perspective
The visible profile is not the evidential identity.
Messenger evidence may combine local application records, Meta account data, browser activity and shared media. Attribution requires correlation between account control, device activity and the conversation itself.
Preserve now
Protect the
best evidence.
- 01Do not reset, update, reinstall or casually browse the application.
- 02Record the device, lock, power and network state.
- 03Identify backups, linked computers and counterpart devices promptly.
- 04Secure known credentials separately and maintain custody records.
Typical deliverables
Acquisition record
Device details, condition, method, tool, integrity information and material acquisition limitations.
Evidence schedule
Relevant conversations, attachments, timestamps, identifiers and supporting artefacts in a reviewable form.
Findings report
Plain-English findings with source references, alternative explanations and express evidential limitations.
Our approach
Proportionate.
Documented.
Explainable.
- 01Authority, objectives and device state confirmed.
- 02Acquisition method selected to preserve the best available evidence.
- 03Findings correlated and tested against alternative explanations.
- 04Clear reporting of methodology, findings and limitations.
Sources and interpretation
Each entry identifies its limited supporting proposition and documentation-check date. General methodology is not a current device-support list. These checks are not laboratory validation; availability and method suitability require assessment for the exact source and configuration.
