Online safety & content laws in South Korea (2026)

South Korea's Democratic Party-dominated National Assembly amended the Act on Promotion of Information and Communications Network Utilization and Information Protection to prohibit distributing 'false or manipulated information' online with intent to harm or gain illicit profit; the Korea Communications Commission may impose fines up to 10 billion won (≈$7.7 million) and courts can award five-times punitive damages. Press-freedom groups and smaller progressive parties condemned the law as an unconstitutional restraint on journalism.

The National Assembly passed legislation criminalizing the creation and distribution of non-consensual sexually explicit deepfake content (up to 7 years imprisonment) and, uniquely, even its possession or viewing (up to 3 years or 30 million won fine). The law was a direct response to a nationwide crisis in which AI-generated deepfake pornography of female students and staff circulated in Telegram group chats, with over 800 cases investigated in 2024 alone.

Amendments to the Network Act enacted in January–February 2024 (Act No. 6360 revisions) took effect, mandating timely cybersecurity-incident reporting by information and communications service providers, introducing a simplified ISMS certification tier, and requiring identification service agencies to protect 'connecting information' (CI). The amendments also established a system for ordering and auditing remedial actions after breaches.

The Constitutional Court ruled that Network Act Article 44-5 — requiring websites with more than 100,000 daily visitors to verify poster identities via Resident Registration Numbers — violated constitutional rights to freedom of expression and informational self-determination, noting the system had not reduced illegal postings and had driven users to foreign platforms. The ruling dismantled the world's most sweeping mandatory online identity-verification regime for ordinary speech.

The Korea Communications Commission (KCC) was established by merging the Korean Broadcasting Commission and the Ministry of Information and Communication, becoming the top broadcasting and telecoms policy authority. Simultaneously, the Korea Communications Standards Commission (KCSC) replaced the Information and Communication Ethics Committee as the dedicated content-standards body with administrative power to order URL blocking and content deletion — publishing a publicly accessible list of blocked sites.

An amendment to the Network Act expanded the real-name verification requirement beyond election sites to cover any website averaging over 100,000 daily visitors, compelling portals like Naver and Daum to collect Resident Registration Numbers before allowing users to post. This created the most expansive mandatory online identity-verification scheme in any democracy and became the legal target of the 2012 Constitutional Court ruling.

An amendment to the Public Official Election Act required users to verify their real identities using Resident Registration Numbers before posting on election-related websites, making South Korea the first country to impose mandatory identity disclosure for online political speech. The measure was justified by concerns over anonymous smear campaigns during elections.

KISA was created in April 1996 as the government's operational arm for internet security policy, cyber-incident response coordination, and safe-internet promotion. It became the technical infrastructure behind cybersecurity enforcement, working alongside content regulators to implement national-level blocking and breach-response directives.

South Korea amended the Telecommunications Business Act to create the ICEC, widely considered the world's first government body specifically tasked with regulating internet content. The ICEC was charged with identifying and blocking material harmful to public order, national security (especially pro-North Korea content), and social morals, establishing a template for administrative internet censorship that later bodies like the KCSC inherited and expanded.
