Foreign Employee Accused of Leaking Confidential Data Through AI Tools in Turkey: Criminal Risks (2026 Updated Guide)

A foreign employee in Turkey is accused of uploading company secrets, personal data or confidential documents to an AI tool. Learn about criminal liability, digital evidence, employer complaints, device examinations and defense strategies.

Artificial intelligence tools are increasingly used by employees to translate documents, summarize contracts, analyze spreadsheets, prepare reports, write software code and process business information. A serious criminal dispute can arise when a foreign employee working in Turkey is accused of entering confidential company information, customer data, trade secrets, personal data, source code, financial records or internal documents into an external AI platform without authorization. An employer may characterize the incident as theft or disclosure of confidential information, unlawful transfer of personal data, unauthorized access to information systems or another criminal offense. However, use of an AI tool does not automatically establish criminal liability. Investigators must determine what information was actually transmitted, who transmitted it, whether the employee was authorized to access the information, what the employee intended, how the AI service processed the information and whether the elements of a specific criminal offense can be established.

Why Can Using an AI Tool Lead to a Criminal Investigation?

The principal risk arises when employees place protected business information into a third-party AI system. The information may leave the employer’s controlled information environment and potentially be processed on external infrastructure.

An employer discovering such activity may initiate an internal investigation and subsequently make a criminal complaint.

Not Every Unauthorized AI Use Is Automatically a Crime

This distinction is critical. A company’s internal AI policy may prohibit employees from using public AI services. Breaching that policy can potentially create employment or disciplinary consequences, but breach of an internal policy alone does not automatically prove a criminal offense.

Criminal responsibility requires the elements of an offense recognized under applicable criminal law.

What Type of Information Was Uploaded?

The defense should determine precisely what information allegedly entered the AI system.

Possible categories include customer information, employee records, financial statements, pricing information, commercial contracts, technical drawings, software code, passwords, strategic plans, tender documents, health information or other personal data.

Different information can create different legal issues.

Trade Secrets Can Create Serious Exposure

If the material contains genuine commercial, banking or customer secrets, unauthorized disclosure can create substantially greater legal risk.

The investigation should determine whether the information was actually confidential, how the company protected it and whether the employee had authority to use or disclose it.

Personal Data Can Create Separate Criminal Questions

Uploading documents containing identifiable individuals’ information can potentially raise personal-data issues in addition to confidentiality concerns.

Investigators should identify exactly which data were allegedly transmitted rather than describing an entire document repository as “personal data.”

Sensitive Personal Information Requires Particular Attention

Documents involving health, biometric or other specially protected information can create heightened legal concerns.

The defense should establish whether such information was actually present in the material submitted to the AI service.

Was the Employee Authorized to Access the Information?

An employee may have been fully authorized to view and use a document for work purposes but not authorized to disclose it externally.

This differs from a situation where the employee allegedly accessed information they were never permitted to obtain.

The distinction can affect the criminal analysis.

Authorized Access Does Not Automatically Mean Authorized Disclosure

A finance employee may legitimately access financial records. An engineer may legitimately possess technical drawings. A lawyer or compliance employee may legitimately review confidential contracts.

The investigation must separately examine whether transmission to the external AI tool exceeded the employee’s authorization.

What Was the Employee Trying to Do?

Intent can be central. An employee who uploads text solely to translate a document presents different facts from someone who deliberately provides confidential information to a competitor.

Investigators should not infer malicious intent merely from the fact that an AI service was used.

Accidental Disclosure and Deliberate Disclosure Are Different

A foreign employee may not understand that information entered into an external service can be processed outside the employer’s environment.

That does not necessarily eliminate every form of legal responsibility, but it can be highly relevant to the required mental element of the alleged offense.

Identify the Exact AI Tool

The phrase “AI tool” is too broad for a criminal investigation.

The defense should identify the exact application, account, version and service used. Enterprise systems with contractual data protections may operate differently from public consumer services.

Determine What the AI Provider Actually Received

Investigators should distinguish allegations from technical evidence.

The employer may know that an employee accessed an AI website but may not initially know what text, documents or data were actually transmitted.

Browser History Alone May Not Prove Disclosure

Evidence that an employee visited an AI website does not necessarily establish what information was entered.

Additional technical evidence may be necessary to reconstruct the alleged activity.

Network Logs Can Become Important

Corporate systems may record domains accessed, upload events, data-transfer volumes or security alerts.

The defense should examine what the logs genuinely prove and what conclusions are merely inferred.

Data Loss Prevention Systems May Trigger the Investigation

Large companies increasingly use systems capable of identifying suspicious uploads or transfers.

An automated security alert should be preserved and technically examined rather than automatically treated as conclusive evidence of a criminal offense.

Screenshots Can Be Misleading

An employer may submit screenshots from internal monitoring systems. Determine when they were created, who created them, whether the underlying data remain available and whether the screenshot accurately represents the alleged transaction.

The Employee’s Computer May Be Examined

If a criminal investigation begins, computers and other digital devices can become important evidence.

The legality of search, seizure and forensic examination should be reviewed carefully.

The Employee’s Phone May Also Become Relevant

If the AI application was used through a mobile device, investigators may seek evidence from the phone.

The scope and legal basis of any digital examination should be analyzed separately.

Personal and Corporate Devices Should Be Distinguished

A company-owned laptop presents different factual issues from an employee’s personal device.

Ownership of the device does not by itself determine whether every form of examination is lawful or whether every file on the device is relevant.

Digital Evidence Must Be Preserved Properly

The integrity of electronic evidence can become central.

Relevant questions include when the device was obtained, who handled it, how forensic copies were created and whether the underlying evidence remained unchanged.

Metadata Can Help Reconstruct Events

File metadata, timestamps, browser records and system logs may help determine when a document was opened, copied or uploaded.

These records should be interpreted by qualified experts where necessary.

Shared Computers Can Create Attribution Problems

Evidence showing activity from a particular device does not always prove which person performed the activity.

If multiple employees had access to the computer or account, attribution should be investigated carefully.

Shared AI Accounts Can Create Similar Problems

Companies sometimes use shared accounts for business tools.

Login records, IP information and device evidence may be necessary before activity can reliably be attributed to a particular employee.

The Employee’s Account May Have Been Compromised

Where the employee denies the activity, investigate whether credentials were shared, stolen or used from another device.

Cybersecurity evidence can become essential in determining responsibility.

Foreign Employees Have the Right to Understand the Accusation

A foreign suspect should understand the nature of the allegation and criminal procedure being conducted.

Language difficulties should not result in the employee signing documents they do not understand.

Interpreter Assistance Can Be Critical

Where the foreign employee cannot adequately understand Turkish, interpretation becomes important during statements and other criminal procedures.

Any inaccurate interpretation affecting the substance of a statement should be documented immediately.

Do Not Sign an Incorrect Police Statement

The employee should review the statement carefully before signing it.

Technical terminology involving AI, cloud systems, file transfers and corporate networks can be mistranslated or oversimplified, potentially changing the meaning of the employee’s explanation.

The Employee’s Statement Should Address the Actual Technology

Statements such as “I uploaded the company’s information to AI” can be dangerously imprecise.

The employee should distinguish what was entered, why it was entered, whether the information was anonymized and what they understood about the system.

Employer Interviews Can Become Evidence

Before the criminal complaint, the company may have conducted an internal interview.

Preserve emails, interview notes and written statements because differences between the internal investigation and later criminal allegations can become important.

Internal Investigation Reports Should Be Examined

An employer’s cybersecurity or compliance report may be influential but should not automatically be treated as independent forensic proof.

Determine who prepared the report, what data were examined and what assumptions were made.

Company AI Policies Matter

Obtain the AI-use policy in force on the date of the alleged incident.

Determine whether the employee received it, understood it and received any relevant training.

Later Policies Should Not Be Applied Retroactively

A company may strengthen its AI policy after discovering an incident.

The investigation should distinguish rules existing when the alleged conduct occurred from policies adopted afterward.

Confidentiality Agreements Should Be Reviewed

Employment contracts, confidentiality agreements, information-security policies and employee handbooks may help establish what information the employee was permitted to use and how confidentiality obligations were communicated.

Criminal and Employment Proceedings Are Separate

An employer may dismiss an employee even while the criminal investigation continues.

An employment-law finding does not automatically determine criminal guilt, and termination does not itself prove that a crime occurred.

Civil Compensation Claims May Also Arise

The employer may claim financial damage resulting from an alleged data leak.

Any claimed loss should be proven rather than assumed from the existence of the incident.

Was the Information Actually Disclosed to Another Person?

This can become a central factual question depending on the alleged offense.

The technical operation of the AI service should be examined rather than assuming that every prompt automatically became publicly available.

Was the Information Used to Train a Model?

This question should be answered according to the actual service, account type, contractual terms and settings applicable at the relevant time.

The prosecution and defense should not rely on generalized assumptions about how all AI systems work.

Was the Data Deleted?

If the company requested deletion or the employee deleted conversations, preserve evidence concerning what happened.

Deletion after an incident can be interpreted in different ways, so chronology and motive should be documented carefully.

Deleting Evidence Can Create Additional Problems

Once an investigation is anticipated, employees and companies should avoid destroying relevant records.

Legal counsel should coordinate evidence preservation promptly.

Foreign Company Headquarters May Hold Important Evidence

If the employer belongs to an international corporate group, security logs or AI-use records may be maintained abroad.

Cross-border evidence collection and preservation may therefore become important.

Independent Digital Forensics May Be Necessary

A forensic expert can help reconstruct whether a file was uploaded, which account was used, what device initiated the transaction and whether employer conclusions are technically supported.

Complex AI-related criminal cases should not be decided solely through assumptions about technology.

Prosecutors Must Still Prove the Individual’s Conduct

Corporate concern about confidential information does not remove the need to establish the defendant’s personal responsibility.

Evidence should connect the foreign employee to the specific alleged disclosure.

A Single IP Address May Not Be Enough

Corporate networks, VPNs and shared infrastructure can cause multiple users to appear under the same external IP address.

IP evidence should therefore be interpreted in its technical context.

AI-Generated Output Can Also Be Evidence

If the output reproduces confidential information, it may help establish what information was entered into the system.

However, investigators should verify the source, date and authenticity of the conversation.

Preserve the Full Conversation

Partial screenshots can omit prompts, warnings and surrounding context.

Where possible and legally appropriate, preserve the complete AI conversation and associated account information.

What If the Employee Used AI Only for Translation?

The purpose of use matters but does not automatically resolve the legal issue.

The defense should examine whether confidential or personal information was transmitted, whether authorization existed and whether the employee understood applicable restrictions.

What If the Information Was Anonymized?

Effective anonymization can materially change the factual analysis.

However, simply removing a person’s name may not be sufficient if the individual or company remains identifiable from the remaining information.

What If the Information Was Already Public?

Information genuinely available to the public may present a different confidentiality analysis.

The employee should preserve evidence showing where and when the information became publicly accessible.

What If the Employer Exaggerates the Amount of Data?

Obtain the actual upload records.

An allegation that “the entire database was leaked” should be tested against forensic evidence establishing the actual files or text transmitted.

Travel Restrictions Can Become Relevant

Depending on the seriousness and procedural development of the criminal investigation, judicial-control measures may potentially affect a foreign suspect’s ability to travel.

Any restriction should be reviewed immediately because foreign employees may need to travel internationally for work or residence purposes.

Residence and Work Permit Consequences Should Be Considered Separately

A criminal investigation can create immigration concerns for foreign nationals, but the existence of an allegation should not automatically be treated as equivalent to a final criminal conviction.

Criminal-defense and immigration strategy should therefore be coordinated where necessary.

Immediate Defense Strategy

A foreign employee accused of leaking confidential information through AI should preserve the relevant devices and accounts, avoid deleting data, obtain the employer’s exact allegation, identify the AI service and account used, preserve the complete conversation where available, obtain applicable company policies, review confidentiality obligations, request the underlying cybersecurity evidence, reconstruct device and account activity, identify potential shared access, preserve evidence of authorization and business purpose, and obtain legal assistance before providing detailed statements concerning complex technical facts.

Frequently Asked Questions

Is using an AI tool at work a criminal offense in Turkey?

No. The criminal issue depends on what the employee actually did, what information was involved and whether the elements of a specific offense are established.

Can uploading confidential company information create criminal liability?

Potentially. The analysis depends on the nature of the information, the employee’s authority, the manner of disclosure and the applicable criminal provisions.

Can uploading customer information create additional risks?

Yes. Personal-data issues may arise separately from trade-secret or confidentiality allegations.

Is browser history enough to prove a data leak?

Not necessarily. Browser history may establish access to a service without proving exactly what information was transmitted.

Can the employer examine the employee’s computer?

Corporate investigations and criminal searches raise different legal issues. The ownership of the computer, workplace policies, scope of monitoring and criminal-procedure requirements should be examined.

What if several employees used the same computer?

Attribution becomes important. Device activity alone may not establish which individual performed a particular action.

Can an internal company investigation prove criminal guilt?

An internal report can become evidence, but its methodology, underlying records and conclusions can be challenged during the criminal process.

What if the employee used AI only to translate a document?

Purpose is relevant, but the content transmitted and applicable authorization still need to be examined.

Can the foreign employee request an interpreter?

Where the suspect cannot adequately understand Turkish, interpretation rights are an important part of ensuring that the person understands the criminal procedure and statement.

What should the employee do first?

Preserve the digital evidence and determine exactly what data were allegedly transmitted, through which account, from which device and for what purpose. AI-related criminal allegations should be reconstructed from technical evidence rather than assumptions about how artificial intelligence systems operate.
