Corporate Data Theft Investigation Services

Employee departures can create information security risks when company documents, customer records, source files, financial information, or confidential business data may have been copied or transferred without authorization.

Xpert Forensics helps organizations investigate suspected corporate data theft through a structured examination of available computer, email, storage, and activity records. The service is intended to support internal investigations, legal teams, HR departments, compliance teams, and corporate security functions.

An employee exit investigation should be scoped carefully, with appropriate authorization, respect for privacy, and preservation of potentially relevant evidence.

When Is an Employee Exit Audit Needed?

Consider an investigation when:

Confidential files may have been copied before resignation or termination.
Large or unusual file transfers are identified.
Business emails may have been forwarded to external accounts.
USB devices or external storage may have been used to transfer information.
Company files may have been synchronized to personal cloud accounts.
A company laptop or workstation has been returned with unexplained changes.
Intellectual property or customer information may have been disclosed.

Evidence Sources for Corporate Data Theft Investigations

Depending on the environment and authorization, relevant sources may include:

Company issued laptops and desktops.
Corporate email systems and available mail archives.
File server access and audit logs.
USB connection artifacts and removable media records.
Browser and download artifacts.
Cloud storage audit logs.
Endpoint security and data loss prevention records.
Available file metadata and document versions.

No single artifact should automatically be treated as proof of theft. Findings should be correlated across available sources.

Employee Exit Investigation Methods

Method 1: Computer and Removable Media Examination

Identify the company devices and the relevant period.
Preserve the device or acquire a forensic image when appropriate.
Examine USB connection records, file access artifacts, downloads, and relevant system activity.
Correlate the records with known file names, timestamps, and available device identifiers.
Report which activities are supported by evidence and which remain uncertain.

Example objective: Assess whether selected company files were accessed or copied to removable media during the review period.

Method 2: Email and Cloud Transfer Investigation

Define the corporate mailboxes and cloud systems within scope.
Collect authorized exports and relevant audit records.
Examine forwarding rules, attachments, external recipients, and file-sharing events.
Correlate email and cloud events with endpoint records where available.
Document relevant communications, transfer indicators, and evidence gaps.

Example objective: Investigate whether confidential documents were sent to external email addresses or shared through cloud storage.

Method 3: Timeline and Data Exposure Assessment

Establish the relevant employee exit or incident timeline.
Identify the data assets and business information of concern.
Correlate file access, downloads, removable media activity, and transfer logs.
Identify confirmed events, suspicious patterns, and unresolved questions.
Prepare a report to support the organization’s internal decision making.

Example objective: Build an evidence based timeline of activity involving specific files before a departure date.

Comparison of Investigation Methods

Method	Primary focus	Potential value
Computer and USB analysis	Local files and device activity	Evidence of access or possible copying
Email and cloud analysis	Communications and online transfers	Records of sharing or external transmission
Timeline assessment	Cross source correlation	A clearer view of events and outstanding questions

Deliverables and Limitations

Depending on scope, deliverables may include:

A technical investigation report.
Relevant artifact references and timelines.
Hash records for acquired evidence, where applicable.
Lists of relevant files, communications, or activity records.
Findings categorized as observed, corroborated, inconclusive, or outside scope.
Recommendations for further evidence collection.

The investigation may not establish the recipient’s identity, the complete contents of a transfer, or the ultimate use of the information if the relevant logs or records are unavailable.

Organizations should obtain appropriate legal, HR, and privacy guidance before collecting employee information or accessing personal accounts.

Frequently Asked Questions

Can you investigate a company laptop after an employee leaves?

Yes, subject to the organization’s authority over the device and the agreed investigation scope.

Can you identify files copied to a USB device?

Available artifacts may indicate USB connections and certain file access or transfer activity. The precise conclusion depends on the operating system, retained artifacts, and corroborating records.

Can deleted company files be investigated?

Potentially. Recoverability depends on the storage condition, file system, encryption, and overwrite activity.

Can the findings support legal proceedings?

A properly scoped and documented technical examination may support internal or legal processes. Admissibility and legal significance depend on applicable law, evidence handling, and the facts of the case.
