Digital Device Forensics Across Computers, Phones and Connected Devices

Look Beyond the Computer and the Phone

Digital evidence lives in tablets, vehicle systems, office equipment, network storage, cloud services and backups as surely as it lives in a laptop, and the record that decides a matter usually spans several of them. Global Digital Forensics identifies the sources, evaluates the access options and connects the available artifacts to the question counsel or the business needs answered, rather than examining one device and hoping it was the right one.

We start with the event rather than with a device list. A document may have been created on a workstation, synchronized to a cloud account, opened on a tablet, printed at an office and retained in a nightly backup, and each of those sources contributes different facts about timing, content and access. Examining them together is how a disputed sequence of events becomes one timeline with the source of every entry recorded, which is what a litigator needs when the sequence is questioned.

To keep those devices in the state they are in now, read the five digital evidence mistakes to avoid.

Device Examiners Designated as Experts in Federal and State Courts

Global Digital Forensics has served law firms and businesses since 1992 with certified examiners who have testified in federal and state courts. Veronica Perez, our Senior Computer Forensic Specialist, has been designated a digital forensics expert in California, Oklahoma and South Carolina state courts and in federal court in Chicago, has taught mobile forensics for the California Department of Justice Advanced Training Center, and is trained in JTAG, chip off, in system programming, vehicle forensics and embedded hardware analysis. Robert Knudsen, a Certified Computer Examiner, has conducted hundreds of computer and mobile device examinations supporting federal and state court matters across the United States.

That bench matters on a device page because the examiner who understands a phone's file system is not always the one who understands a vehicle's telematics module or a printer's job log. We match the examiner to the device, and the examiner who does the work is the examiner who explains it.

Tablets, Mobile Devices and the Accounts Behind Them

Tablets and other mobile devices hold messages, documents, photographs, application records and account information, and much of what a user sees on the screen actually lives in an associated cloud account or backup. Device access and cloud access are separate collection questions with different permissions, retention and technical limits, and we plan them separately so that nothing is assumed to be on the device when it is on a server.

A device extraction does not necessarily include everything an application displays. Some content is stored remotely, some is encrypted and some is no longer retained. We document the device model, the operating system, the account relationships and the available backups before choosing a method, and our mobile device forensic services set out the collection scope in detail.

If the phone is still in use, call (800) 868-8189 before it is wiped, traded in or restored from a backup.

Vehicle Navigation, Infotainment and Event Data

Navigation, infotainment, telematics and event recording systems each hold different information, from paired device records, destinations and route history to event specific vehicle data, and availability depends on the vehicle, the installed systems, the retention and the supported access methods.

We confirm whether the vehicle reached a destination by joining the navigation record with telematics and the event data recorder, which captures specific events rather than every trip. Interpretation draws on the source, the timestamp behavior and the recording conditions, which is why we preserve the vehicle and its associated accounts under an agreed plan before repairs, resets or software updates change the record. Our vehicle forensics page describes the service.

Vehicles scheduled for repair or return to a lender need a preservation plan first; tell us where the vehicle is and when it is due to move.

Tell Us Which Event You Need to Understand

Describe the event, the devices and accounts still available and your deadline, and a senior examiner will scope the collection and the examination with you. The initial consultation is free, and the 24/7 hotline is (800) 868-8189.

Office Equipment, Voicemail and Shared Storage

Printers, copiers, scanning systems and voicemail platforms retain job records, stored documents, messages and configuration information, with retention that varies by model, settings and subsequent use, so no one should assume that every printed document is still available or that every one is gone.

Network attached storage, file servers and offsite backups frequently hold earlier versions or material missing from the current workstation. Our collection plan identifies who administers each source, whether backups can be restored and what changes a restoration could introduce, and we preserve the original backup material and document any restoration used for analysis.

Embedded Storage and Specialist Access

Some devices give up their contents only through methods beyond a normal export or connector, through a supported debug interface, board level work or an assessment of removable storage. Encryption and proprietary formats can stand between physical access and readable content, so we assess both before anyone commits to an invasive step.

We discuss feasibility, risk and authorization first, and the examination plan explains why the method is needed, how the original device will be handled and which data the method will reach. Related capabilities include embedded systems forensics and integrated circuit forensics.

Build the Source Map Before the Evidence Disappears

For every device and service we record the owner, the administrator, the account, the relevant period and the retention risk, including the business applications and databases that exchanged information with it. A cloud export, a device extraction and a server log can describe the same event differently, and those differences are reconciled on the record rather than silently merged.

The work product identifies what was collected, the method, the custody and integrity records, the material findings and the limitations of each source, so the legal team can see the strength of the account before the other side tests it. Tell us which event you need to understand and which devices or accounts remain available, and we will scope the collection and examination around it.
