What this law does

Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.

Article 48(1) prohibits intruding into an information and communications network without legitimate access authority or beyond the scope of permitted authority. The Supreme Court held in Yanolja Co. v. GC Company (2021Do1533, 12 May 2022) that scraping publicly available data without defeating an authentication or access-control measure did not violate this provision as charged.

Paragraph (4), added January 23, 2024, separately prohibits installing, transmitting, or distributing a program or technical device whose purpose is to bypass a network's normal protection or authentication procedures, reaching a scraper's own circumvention tools directly even though paragraph (1)'s basic prohibition predates it and remains the article's core text.
