Illegal Surveillance Allegations

Overview

Illegal surveillance allegations (불법사찰 의혹) refer to suspicions that state intelligence agencies, investigative agencies, military intelligence agencies, and others collected, wiretapped, or monitored the communications, location, personal details, and activities of individuals or organizations without following procedures prescribed by law, or in ways that exceeded the scope of their duties. Because this directly conflicts with the core values of the constitutional order — the confidentiality and freedom of private life, the secrecy of communications, and democratic control — it generates significant political and legal repercussions. Indeed, whenever such suspicions have been raised, they have been followed by hearings of the National Assembly Intelligence Committee, special prosecutor and Board of Audit and Inspection investigations, and prosecutorial and police investigations, repeatedly triggering debates on intelligence agency reform.

Concept and Legal Standards

Illegal surveillance can be broadly divided into ① wiretapping of communications conducted without a court warrant, ② out-of-purpose inquiries into communication fact-confirmation data (call records and originating base station information), ③ location information tracking, ④ monitoring of the activities and personal details of civilians, and ⑤ theft of information through hacking and the distribution of malware. Relevant laws include Article 17 (Confidentiality and Freedom of Private Life) and Article 18 (Secrecy of Communications) of the Constitution, the Protection of Communications Secrets Act, the Personal Information Protection Act, the Act on the Protection and Use of Location Information, the National Intelligence Service Act, and laws concerning military protection facilities. The Protection of Communications Secrets Act in principle requires a court warrant for communications-restricting measures such as wiretapping, prohibits use for purposes other than those stated and provision to third parties, and provides for criminal punishment in case of violation. The National Intelligence Service Act likewise stipulates a prohibition on involvement in domestic politics and limits on the scope of duties.

Historical Background

In South Korea, controversies over surveillance have existed since the era of the Korean Central Intelligence Agency (중앙정보부) and the Agency for National Security Planning (안전기획부). Numerous testimonies and documents have been made public showing that in the 1970s and 1980s there was extensive monitoring and surveillance of politicians, journalists, and student activists, and even after democratization suspicions of political involvement by intelligence agencies did not cease. In the 2000s, suspicions of surveillance of civilians by the military's Defense Security Command (기무사) became an issue, and in the 2010s the National Intelligence Service's introduction of hacking programs, cyber psychological warfare, and the comment manipulation incident successively came under scrutiny. In 2018, suspicions emerged that the Defense Security Command had drafted a document examining the imposition of martial law, leading to discussions on reorganizing and downsizing military intelligence agencies. In each case, investigations, trials, and parliamentary inquiries proceeded, and loopholes in the scope of duties and internal controls were pointed out.

Issues and Control Mechanisms

The core issue is the balance between national security and investigative efficiency on the one hand and the protection of citizens' fundamental rights on the other. The activities of intelligence agencies are inherently secret, making external oversight difficult, and suspicions are often revealed belatedly through whistleblowing or media reports. Control mechanisms include closed-door reports to the National Assembly Intelligence Committee, internal audits of the National Intelligence Service, audits by the Board of Audit and Inspection, investigations and sanctions by the Personal Information Protection Commission, oversight of communications data management by the Korea Communications Commission, and judicial review of warrants. However, issues such as the effectiveness of Intelligence Committee reports, the obligation of post-hoc notification, the statute of limitations, and the allocation of investigative authority remain tasks for improvement.

Representative Types of Allegations

Wiretapping of communications and out-of-purpose inquiries into call records
Surveillance of the activities of politicians, journalists, civic organizations, and labor unions
Theft of personal information using hacking tools and malware
Leaks of internal information by investigative agencies and the drafting of surveillance reports
Suspicions of psychological warfare related to elections and public opinion and links to opinion manipulation

Latest Trends

In the course of the declaration of martial law at the end of 2024 and the subsequent investigations, suspicions were raised that intelligence agencies, the military, and the police compiled lists of specific individuals or considered operating surveillance and arrest teams, and in 2025 the National Assembly and investigative agencies continue to work to uncover the truth. Strengthening oversight of intelligence agencies and establishing internal checks have emerged as major agenda items in the political sphere, and the need to revise the Protection of Communications Secrets Act and the Personal Information Protection Act is being discussed once again. At the same time, as surveillance and tracking technologies using facial recognition, location information analysis, and generative AI spread, the regulatory vacuum regarding digital surveillance has emerged as a new issue. The Personal Information Protection Commission and academia are proposing alternatives such as ensuring the effectiveness of the principle prohibiting use for purposes other than those stated, conducting prior impact assessments for algorithm-based surveillance, and establishing an independent external oversight body for intelligence agency activities. Internationally as well, similar surveillance and wiretapping scandals have been reported one after another, making the securing of intelligence agency transparency and democratic accountability a common task.
