₩3.4 billion for one chaebol: South Korea's 2026 SMB tech-data theft cliff.
On 4 March 2026 the Fair Trade Commission (KFTC, South Korea's antitrust regulator) closed a ₩3.429 billion consent decision against Hyosung and Hyosung Heavy Industries over what it found was improperly demanding subcontractor technical materials while outsourcing power-equipment component production. Three weeks later it fined Hansei Mobility ₩36 million for emailing a supplier to demand three drive-shaft technical files without the written notice the law requires. The SME Ministry's new Technology-Theft Hotline took 20 reports in its first month of operation — matching the entire 2024 annual baseline. A Subcontracting Act amendment due mid-2026 adds "Korean-style discovery", evidence-preservation orders, and a shifted burden of proof onto the prime contractor.
01The pain
Twenty reports in one month. That is what the South Korean SME Ministry's "Technology-Theft Hotline" (기술탈취 신문고) took in its first month, matching the entire 2024 annual baseline of 20 cases and exceeding the 16 logged across all of 2025.1 Korean small and mid-size suppliers hand over CAD drawings, bills of materials, process specs and failure-analysis files to chaebol prime contractors as a condition of getting on the order book.
On 4 March 2026 the Fair Trade Commission (KFTC, South Korea's antitrust regulator) closed a consent decision against Hyosung and Hyosung Heavy Industries. The company will put ₩3.429 billion (about $2.5 million) into supplier-protection funds for what the KFTC framed as "전력·동력기기 부품 생산을 위탁하면서 수급사업자 기술자료를 부당하게 요구한 혐의" (improperly demanding subcontractor technical materials while outsourcing power-equipment component production).2 On 29 March it fined Hansei Mobility ₩36 million for emailing a supplier to demand three drive-shaft technical files (management plans and failure-analysis documents) without the written notice the law requires. The regulator said it would "intensively monitor procedural breaches going forward".3
A Subcontracting Act amendment due mid-2026 adds what officials are calling "Korean-style discovery": expert fact-finding, evidence-preservation orders, mandatory submission of materials to the KFTC, and a shifted burden of proof onto the prime contractor. For the first time, the cost of bringing the case will not sit entirely with the supplier.1

대기업에 기술을 탈취당했는데 법으로 풀면 된다고요? · Clien News board — 19 comments / 18 distinct posters on the 2023-04-19 thread arguing that the legal route is impractical for SMB victims; follow-ups on the same board (#18037836 and others) carry the pattern through 2024–2026, and the 2026 KFTC press release explicitly cites the cost-of-recourse problem as the rationale for the discovery-system reforms — multi-year operator recurrence (>3 years) on the same asymmetry.
02Who solves this today
Three providers that publicly market into the wedge Korean SMB suppliers reach for when a chaebol prime asks for the next file: document-DRM, watermarking, and data-loss-prevention platforms that build the kind of access-logged paper trail KFTC and the new evidence-preservation regime expect. Coverage is thin on Korean-domestic SMB-priced offerings — the floor on this page is 3, and the gap is real. Each was fetched live on the date of writing. Inclusion is not endorsement.
Probed and dropped (each WebFetched on the date of writing): markany.com/eng/ (HTTP 404 — English subdirectory missing; main Korean homepage was reachable and is the one cited above); ahnlab.com/en (HTTP 200, hero-section body returned empty — could not capture a verbatim self-claim relevant to EDRM/document-DRM); igloo Inc. iglooinc.co.kr/en/ (ECONNREFUSED — Korean SOC/security vendor unreachable from the fetcher; the same Korean fintech-style TLS reachability problem the catalogue has hit on prior SK pages); softcamp.co.kr/eng/ (HTTP 404 — English subdirectory missing); proofpoint.com (acquirer of Tessian — global vendor, not Korean-domestic, dropped on relevance to the SMB-supplier wedge). KFTC, Shin & Kim and other primary sources are referenced for §01 framing and are not listed as vendors. Hyosung, Hyosung Heavy Industries, Hansei Mobility and Lotte Healthcare appear in §01 / §03 only as parties to public-record KFTC decisions or named in operator forum threads, not as solution vendors. Listed providers publicly self-market in one of the wedges named above. Inclusion is not endorsement.
