Account, backup and synchronised evidence

Mobile cloud
Forensics.

Lawful acquisition and examination of available cloud and account data can extend, corroborate or qualify what remains on a handset. It is a complementary evidence route, not a guaranteed substitute for the device.

Potential sources

Evidence beyond
the handset.

We identify relevant services, confirm authority and access, preserve available data and document what the provider returned. Service support, content and authentication requirements change over time.

01

Apple ecosystem

Available iCloud device backups, synchronised account content, photographs, contacts, files and related Apple-device sources.

02

Google ecosystem

Available Google Timeline or location-related records from supported device, account or exported sources, plus Google Drive, Gmail, Keep, account activity, synchronised records and Android backup material.

03

Messaging services

Available WhatsApp backups or authorised account collection, Telegram cloud chats and other service-held records where supported.

04

Microsoft and email

Available Microsoft 365, OneDrive and mailbox data, plus supported email accounts collected through authorised service access.

05

Huawei services

Available Huawei account, backup and synchronisation material considered alongside compatible device evidence.

06

Social and storage

Available hosted social-media, content-sharing and cloud-storage records relevant to the agreed instruction.

Critical qualification

Configured, retained
and lawfully accessible.

Availability depends on the service and region, account configuration, credentials or valid session material, multi-factor authentication, encryption, retention, subscription status, provider changes and lawful authority. A listed source is a potential acquisition route, not a promise that a particular account or item can be recovered.

Examination scope

Collect.
Correlate.
Qualify.

01Authority, account ownership, relevant dates and proportional scope confirmed.

02Authentication and multi-factor requirements assessed without unsafe credential transmission.

03Provider-returned data preserved with acquisition records and integrity information where available.

04Cloud records correlated with the handset, backups, linked devices and counterpart evidence.

05Missing fields, changed media, unsuccessful access and service limitations reported expressly.

Imported evidence

Existing forensic
images and exports.

Where direct acquisition is unavailable or another examiner has already collected the data, we can assess compatible mobile backups, file-system images, third-party forensic exports, device images and selected low-level acquisitions. Provenance and completeness are checked before reliance.

Source-specific scope

Cloud capability
and evidence routes.

Documentation-check dates are shown beside each source. These dates record documentation checks, not tests of D3's installed tools. Reconfirm access, region, version, authority and collection effects for every instruction.

Scroll horizontally on narrow screens. An unsupported route, failed authentication and a successful return with no relevant records are different outcomes and must be reported separately.

Route distinctions

A device backup is a configured snapshot. Synchronisation can propagate changes. A provider export is a selected representation. Direct account collection depends on supported interfaces and authority. A linked session may change account state. An imported image is an existing acquisition whose provenance and scope must be checked.

Cross-border and account effects

Confirm applicable jurisdiction, authority, proportional scope, storage and transfer arrangements before collection. Access can generate account events or notifications. Provider formats, fields, authentication and retention can change or fail. No account ownership or administrator role alone establishes authority over every third-party record.
