Seoul puts a three-year floor under sentences for leaking state secrets to any foreign entity
South Korea's revised Criminal Act took effect on September 13 and drops the requirement that a leak benefit an enemy state, so conduct police logged a record 33 times last year now carries three to 30 years.

What happened
- South Korea's revised Criminal Act took effect on September 13, extending espionage from acts benefiting enemy states to acts on behalf of any foreign country or organized entity.
- Obtaining, collecting or disclosing state secrets for a foreign entity now brings a minimum of three years in prison and a maximum of 30.
- Before the change, an espionage charge required the involvement of an enemy state, which in practice meant North Korea.

Why it matters
- exposure An engineer weighing an offer from a Chinese memory firm is now pricing three years of personal liberty as the floor.
- constraint Hiring people who already know the process was the pathway export controls left open to CXMT and YMTC, and the price of that pathway just went up on the seller's side.
- precedent Technology theft is now a national security matter in Korean law, so state investigative powers arrive where a company once handled a departing employee through its own HR file.
- cost The penalty falls entirely on individuals, which makes a sentencing amendment the cheapest protection available for an $880 billion semiconductor hub plan.
The working part of the revision is the phrase that replaced "enemy state." Anyone who obtains, collects or discloses state secrets on behalf of any foreign country or organised entity now faces at least three years in prison and as much as thirty [1][6]. The revision does not say how a privately held DRAM process recipe becomes a state secret. That definition decides how far the statute reaches into Samsung and SK Hynix, which together dominate the global memory chip market [12].
Twenty-seven years sit between the floor and the ceiling [1], and it is the floor that binds. Prosecutors who used to fall back on trade secret statutes carrying lighter penalties and less deterrent force now have a charge with a three-year minimum attached [5].
Price it from the recruiting side. US export controls have slowed CXMT's and YMTC's access to the most advanced manufacturing equipment while both build memory capacity, and human capital is the alternative pathway to closing the technology gap [11]. Five former Samsung Electronics employees were indicted over an alleged transfer of critical DRAM manufacturing technology to CXMT [8]. Whatever those five were offered was set against the penalties the old law allowed. An offer made after September 13 has to cover three years at minimum.
The counter-argument is enforcement. Police reported 33 technology leak cases in 2025, a record, with more than half linked to China, so at least 17 [7][3]. All of them were found under the narrow law. The amendment raises the penalty on cases that were already being detected. It does not find more of them, and an unchanged probability multiplied by a longer sentence moves a recruiting premium less than the thirty-year ceiling suggests.
Legislators passed the revision on 26 February 2026, the first major overhaul of the espionage provision in 73 years, and commencement followed 199 days later [9][3][2].
cryptobriefing.com, reporting the change, wrote that Beijing may interpret the legislation as targeted, given that over half of the reported leak cases were linked to Chinese entities [14]. I'd expect the durable effect to sit in the labour market: the outside option for a Korean process engineer now carries a personal criminal price, and the firms that were buying that knowledge either pay it in cash or go without.
What to watch
- The first prosecution brought under the revised article, and whether a court treats a company's process technology as a state secret.
- Whether the 2026 police count of technology leak cases comes in above or below the 33 reported for 2025.
- Any Chinese response to a law that cryptobriefing.com expects Beijing to read as aimed at its memory firms.
