Korea Internet & Security Agency (KISA) is moving to bolster its response together with landline and internet phone providers.
Korea Internet & Security Agency (KISA) said on the 8th that it will hold a "briefing session for providers to strengthen capabilities to respond to illegal spam" on the 11th at SETEC in Seoul for landline and internet phone (VoIP) providers.
The session was prepared to raise providers' understanding of the law and their on-the-ground response capabilities, as obligations for information and communications service providers to take measures to prevent illegal spam were strengthened under the amendment to the Act on Promotion of Information and Communications Network Utilization and Information Protection, promulgated in March.
Since the government drew up a "comprehensive plan to prevent illegal spam" in 2024 through a joint effort by related ministries, text spam has been on the decline. According to Korea Internet & Security Agency (KISA), the number of reported and detected spam texts fell about 91%, from 150.2 million in the second half of 2024 to 102.88 million in the second half of 2025.
By contrast, during the same period, reported and detected voice spam cases surged more than 60%, from 5.04 million to 8.73 million. In line with this, the role of landline and internet phone providers in blocking voice spam is becoming more important, Korea Internet & Security Agency (KISA) noted.
Korea Internet & Security Agency (KISA) will use the session to brief providers on their obligations to prevent illegal spam, methods for monitoring and taking action against illegal spam, the current status of real-time voice spam blocking, and procedures for handling civil complaints. It will also share plans and timelines to disclose to the public the volume of spam reports by each landline and internet phone provider. The session is open to anyone in charge of spam-related work at landline and internet phone business sites.
Heo Hae-nyoung, head of the User Protection Division at Korea Internet & Security Agency (KISA), said, "To effectively block illegal spam, active on-site responses and swift action are essential along with institutional improvements," adding, "We will continue to raise providers' understanding of the law and support the strengthening of response capabilities to produce tangible reductions in voice spam that the public can feel."
