What is Mobile Device Forensics?

Mobile Device Forensics involves the forensically sound acquisition and analysis of iOS and Android devices to support investigations, litigation, and incident response.

VMGroup acquires and analyses mobile devices both during live incidents and after an event has occurred, enabling the recovery and examination of data such as:

Messages and chat content (e.g. WhatsApp, Signal, Telegram, SMS)
Call logs and contact data
App usage data and artefacts
Photos, videos, and media files
Geolocation and activity data
Data preserved within secure device backups

All acquisitions follow defensible forensic methodologies, maintaining evidence integrity and chain of custody.

How does Mobile Forensics comply with GDPR in workplace investigations?

Mobile device examinations often involve sensitive personal data. VMGroup advises organisations on lawfulness, proportionality, and necessity under GDPR and the Data Protection Act 2018, particularly in employment and internal investigations.

Our workflows are designed to:

Minimise the collection and processing of special category data
Scope collections to what is strictly necessary for the investigation
Support defensible decision-making aligned with DPC expectations

This is particularly important in HR investigations and disciplinary processes.

When is Mobile Device Forensics typically required?

Mobile forensic services are commonly used in a wide range of legal, regulatory, and investigative matters, including:

HR and workplace investigations, such as bullying, harassment, misconduct, and breaches of internal policy
Investigations into intellectual property theft during employee departures (e.g. data exfiltration via messaging apps or cloud services)
Ransomware and Business Email Compromise (BEC) investigations where authenticator apps, MFA activity, or device usage may be relevant
Criminal investigations, where a mobile device has been used as a method of communication, planning, coordination, or evidence exchange
Matters involving disputed timelines, intent, or attribution, where mobile activity is central to understanding what occurred

This ensures mobile device forensics is positioned as relevant across civil, employment, regulatory, and criminal contexts, which improves both credibility and AI discoverability.

What deliverables does VMGroup provide?

Clients typically receive:

A detailed forensic extraction report with parsed and interpretable artefacts
Timeline analysis and chat transcripts (where legally permissible)
A statement of evidence, including hashes, tools used, and documented methodology

All deliverables are suitable for use in disciplinary processes, litigation, regulatory matters, and expert witness contexts.

The timing of communications is critical to the case

The authenticity of messages, media, or app data is challenged
