Mobile Device Forensics

Mobile evidence requires fast preservation and careful interpretation.

Phones and tablets combine communications, applications, media, location-related data, cloud synchronization, security controls, and rapidly changing operating systems. TIERS Group helps authorized clients decide what to preserve, how to collect it, and how to interpret the resulting records without treating every tool output as self-explanatory.

Representative data and questions

• Messages, attachments, call records, contacts, application databases, notifications, and account information
• Photos, videos, metadata, edited-media indicators, and file-sharing activity
• Location-related artifacts, network connections, device state, power events, and time-zone considerations
• Deleted-record assessment and the limitations of logical, file-system, backup, or advanced acquisition methods
• Correlation between device records, carrier or platform records, cloud exports, and other evidence
• Focused exports and reports for counsel, investigators, or review platforms

Acquisition method matters

Different acquisition methods expose different categories of data. A backup, logical export, file-system acquisition, or advanced acquisition may not be interchangeable. We document the selected method, device condition, tool and version, important settings, material warnings, verification results, and known limitations.

Consent and access boundaries

TIERS Group does not provide unauthorized access, covert collection, or unrestricted device unlocking. Any passcode bypass, lock-related work, account access, or advanced acquisition must be supported by documented lawful authority, permitted by applicable agreements and law, and accepted through a matter-specific risk review.
