Mobile Phone Forensics — Overview & Workflow

Collections • Preservation • Analysis • Reporting

We acquire and analyze iOS and Android devices using defensible methods that preserve metadata and chain of custody — delivering timelines, chats, media, and app artifacts you can rely on.

What We Do

Purpose‑Built Forensics

  • Custodian‑friendly collection options: onsite, remote, or in‑lab.
  • Defensible documentation: consent, scope, hash logs, chain of custody.
  • Attorney‑aligned reporting focused on facts, timelines, and policy impact.

Common Matters

  • Departing employee/IP theft; insider risk
  • Harassment/misconduct investigations
  • Regulatory & litigation discovery

Devices & Data Types

Platforms

  • iOS (iPhone, iPad) — supervised/unsupervised
  • Android — managed (MDM) & unmanaged/BYOD
  • Business & personal devices (policy‑permitting)

Core Artifacts

  • Texts/SMS, iMessage, call logs
  • Chat apps (policy‑ & encryption‑permitting)
  • Photos, videos, audio/voicemail
  • Contacts, calendars, notes
  • Locations, Wi‑Fi, Bluetooth history

App Evidence

  • Email (Exchange/Gmail clients)
  • Enterprise apps (Teams/Slack/Zoom)
  • Cloud storage & sharing traces
  • Browser history, downloads

Legal Authority & Consent

  • Counsel‑directed scope with documented owner consent or legal authority (warrant, subpoena, company policy, or MDM agreement).
  • Least‑intrusive approach first; target work data while respecting privacy boundaries.
  • Works council/region‑specific protocols where applicable.

Acquisition Methods

Logical / Targeted

  • Consent‑based extractions of messages, media, and app data
  • Cloud backups (iCloud/Google) when appropriate
  • Rapid triage to confirm relevance

Advanced Options

  • Selective file‑system/data‑partition acquisitions (device‑ and OS‑dependent)
  • Journals/artifact pulls for deleted item recovery (where supported)
  • Encrypted devices: workflow for passcodes/MDM unlocks or fallback strategies

Standard Workflow (Client‑Facing)

  1. Intake & Scoping: Allegation, custodians, device inventory, policies, region/privacy checks.
  2. Authority & Consent: Counsel letter, consent forms, device custody and access approvals.
  3. Acquisition: Logical/targeted or advanced file‑system methods; capture hashes and logs.
  4. Verification: Validate image integrity; document environment and tool versions.
  5. Parsing & Processing: Normalize timezones; extract chats, media, locations, app artifacts.
  6. Analysis: Build event timelines; correlate with email/chat/endpoint activity if applicable.
  7. Reporting: Findings memo with exhibits; optional expert declaration.
  8. Preservation: Evidentiary storage and retention aligned to matter policy.

Analysis & Deliverables

What You Receive

  • Collection & chain‑of‑custody report (hashes, method, scope)
  • Timeline workbook (messages, calls, locations, media)
  • Exhibits: chat exports, screenshots, and selected artifacts
  • Findings summary: issues, evidence, and recommended next steps

Optional Add‑Ons

  • Audio/video transcription; translation
  • Handwriting OCR and form extraction
  • Cross‑source correlation (M365, endpoints, SaaS)

Triage vs. Full Forensic

Triage (QuickLook)

  • Rapid confirmation of relevance and scope
  • Targeted extractions of key apps/time windows
  • Ideal for early case assessment or HR intake

Full Forensic

  • Broader coverage; deeper artifact recovery
  • Enhanced timelines and cross‑system correlation
  • Suited for litigation, regulatory, or complex matters

Security & Privacy

  • Least‑privilege access; role‑based controls; encrypted storage in transit/at rest.
  • Respect for personal content on BYOD devices; targeted extractions to work data where possible.
  • Region‑aware handling and documentation for cross‑border matters.

Engagement & Onboarding

Engagement Options

  • QuickStart: Single device, targeted scope, fixed fee, rapid readout.
  • Multi‑Device: Parallel acquisitions with weekly status updates.
  • Advisory: Policies, BYOD playbooks, and readiness training.

Onboarding Checklist

  • Signed SOW; custodian/device list; OS & passcode status
  • Authority/consent forms; MDM/work profile details
  • Timeline targets; reporting format preferences
