Messages & groups
Available one-to-one and group messages, replies, reactions, edits and service events reconstructed with their context.
Messaging application evidence
Viber
Forensics.
Forensic examination of Viber messages, calls, communities, shared media, account information and available local or backup artefacts.

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
Available voice and video call records, participants and timestamps correlated with contacts and wider device activity.
Communities & channels
Membership, administrator activity, posts and associated identifiers examined where relevant and available.
Media & files
Images, video, voice messages, documents, stickers, thumbnails and cached material assessed with file-system traces.
Account & contacts
Telephone registration, profile data, contacts, linked computers and account changes considered for attribution.
Backups & deleted data
Available backups, desktop records, notifications, media and database remnants assessed without guaranteeing recovery.
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 messages, calls, groups, attachments and configuration.
Backup and account
Configured application backups assessed by platform, date and retained content.
Existing linked endpoints
Existing linked-client records may corroborate the handset.
Limits and corroboration
Backup and transfer features do not establish that deleted content remains. Lawfully obtained counterpart records may corroborate the source.
Evidential perspective
Local records and backup choices define the evidence.
Viber content may be distributed between the handset, linked computers, media storage and configured backups. The examination documents which sources were available and what each can properly establish.
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.
