Complete computer forensic services in Illinois: forensic imaging, artifact analysis, deleted data recovery, expert reports, and court testimony statewide.
Computer forensic services in Illinois cover every step from device intake to courtroom exhibit. Whether the matter is a departing employee suspected of copying source code, a fraud investigation involving accounting workstations, or a criminal defense case where the prosecution relies on computer evidence, our Illinois computer forensic services are structured as discrete, priced deliverables you can combine into a scope that fits the matter and the budget.
Emergency Preservation: an on site or same day acquisition to freeze the state of a computer before spoliation risk grows. Forensic Imaging: bit for bit copy of drives, SSDs, external media, servers, or virtual machines, with dual hash verification. Targeted Data Recovery: recovery of deleted files, browser history, chat logs, cloud sync artifacts, and system logs. USB and External Device Analysis: identification of every USB device ever connected, when, and what files were touched. Network Artifact Extraction: parsing browser history, cookies, cached credentials, and cloud client sync logs. Timeline Reconstruction: building a court ready chronological narrative from $MFT, journal files, and application logs. Email Preservation and Analysis: full mailbox capture from Outlook, Apple Mail, Thunderbird, or O365/Google Workspace. Expert Report Drafting: Illinois formatted expert reports with exhibits, hash tables, and methodology sections. Declaration Support: sworn declarations for TRO and injunction motions. Deposition and Trial Testimony: Illinois experienced testifying experts. Rebuttal of Opposing Reports: written or oral critique of another expert’s methodology and conclusions.
Computer forensic engagements in Illinois follow a structured workflow: lawful preservation, forensic imaging, targeted examination, and courtroom ready reporting. We handle Windows, macOS, Linux, virtualized environments, RAID sets, and cloud synced endpoints, and we scope every engagement so counsel knows exactly what is being purchased at each phase.

Windows, macOS, and Linux acquisitions in Illinois cases use write blockers (Tableau, WiebeTech) and validated imagers (FTK Imager, Guymager, X Ways). Server and virtualized environments are captured live where required using KAPE and F Response. Full disk decryption workflows cover BitLocker, FileVault 2, LUKS, and third party volumes when keys or credentials are lawfully available. Analysis then leverages Magnet AXIOM Cyber, X Ways, and Autopsy for artifact carving, timeline building (plaso/log2timeline), NTFS $MFT and USN journal parsing, ShellBags, Prefetch, ShimCache, and browser + cloud sync artifact review.
A digital forensic engagement is not a single deliverable it is a defined chain of services: intake and scoping, lawful preservation, forensic acquisition (imaging or extraction), examination against agreed upon questions, reporting, and, where needed, declaration or courtroom testimony. Each of these steps has its own cost, its own risk profile, and its own Illinois legal considerations. Understanding what you are actually purchasing at each step is the difference between evidence that helps your case and evidence that gets excluded.
Computer based evidence in Illinois cases must clear both authentication under Ill. R. Evid. 803(6) (business records) (business records and electronic authentication) and 815 ILCS 333 (Uniform Electronic Transactions Act) and reliability under Frye (Donaldson v. Central Illinois Public Service Co.) when the underlying technique is novel. We prepare acquisition logs, hash verifications (MD5, SHA 1, SHA 256), and examiner declarations tailored to Illinois Court of Common Pleas and Seventh Circuit requirements. For criminal matters we align with Brady disclosure obligations and Ill. S. Ct. R. 412 (criminal discovery) (discovery and inspection) discovery; for civil matters we align with Ill. S. Ct. R. 214 (requests for production) document production and § 2033 requests for admission workflows.
Illinois is the fifth largest state economy in the United States in the world on a standalone basis, and that footprint shapes the digital forensic work we see: Downtown Chicago and West Loop tech corridor IP theft and trade secret matters; manufacturing, healthcare, and logistics sector fraud, IP, and contract disputes in Chicago; Northwestern Medicine, Rush, and University of Chicago Medicine healthcare and biotech breach investigations in Chicago; logistics, trucking, and agricultural fraud across Central Illinois and Downstate; and cross border criminal defense matters throughout the Collar Counties (DuPage, Lake, Will, Kane, McHenry) and Downstate Illinois. Every industry brings its own artifact set GitHub commits, cloud IDE logs, DAW project files, medical device telemetry, EDI trade documents and we build the exam plan around what actually matters to the case.
Preservation and imaging typically starts around $1,500 $3,000 per device. Full examinations depend on scope; most Illinois engagements land between $5,000 and $25,000 including report.
