Korea's expanded espionage law:
why manufacturing SMEs must act

Protecting drawings, process recipes, samples and customer data is now part of supplier competitiveness.

Sep 16, 2026 · BIZPECTRA Editorial · 7 min read

Effective September 13, Korea expanded espionage offenses beyond acts involving an “enemy state” to cover foreign countries or equivalent organizations. Strategic industries are the policy focus, but suppliers with limited security resources face acute exposure.

What changed
  • The scope now covers espionage for any foreign country or equivalent organization.
  • The new offense carries a minimum three-year prison term.
  • Industrial-technology and trade-secret laws remain relevant.
  • Technology leakage without the old North Korea nexus can face stronger scrutiny.

A 30-day SME plan

Week 1: inventory

Classify recipes, plating conditions, material specifications, customer drawings and prices as critical, restricted or general.

Week 2: access and export

Remove shared passwords, revoke access promptly and record USB, email and cloud exports.

Week 3: supplier contracts

Cover subcontracting, retention, incident notice, sample destruction and audit rights—not just NDA language.

Week 4: response drill

Assign responsibility for evidence preservation and customer, law-enforcement and insurer contact.

BIZPECTRA view

Stronger law does not automatically protect know-how. SMEs need asset classification, least privilege, employee-exit control, subcontractor discipline and incident records. Secure handling of customer information is a global-sales trust signal.
