South Korea’s top HUMINT agency probes potentially catastrophic data breach
July 29, 2024 1 Comment
IN A HIGHLY UNUSUAL move, authorities in Seoul have publicly acknowledged a data leak that may have resulted in the outing of a number of South Korean undercover human intelligence (HUMINT) operatives abroad. The South Korean Ministry of National Defense said on Sunday it was investigating an alleged link of highly sensitive data belonging to the Korea Defense Intelligence Command (KDIC).
Formed under American tutelage in 1946, KDIC is today considered South Korea’s most secretive intelligence agency. It operates under the Defense Intelligence Agency (DIA), which makes it part of the Ministry of National Defense’s chain of command. Unlike DIA’s civilian counterpart, the National Intelligence Service, KDIC rarely surfaces in unclassified news reporting, and it almost never issues press releases. Its operations primarily involve HUMINT activities, thus making it South Korea’s most active HUMINT-focused agency.
Predictably, KDIC’s primary intelligence target is North Korea. The agency gathers much of its intelligence on the North through an extensive network of undercover officers operating with diplomatic credentials. KDIC also handles non-official cover (NOC) operatives, who are located mostly in Asia. There have been periodic claims in the unclassified literature that some KDIC NOCs have operated inside North Korea at times –though such claims remain speculative.
On Saturday, the Seoul-headquartered Yonhap News Agency alleged that classified information relating to KDIC had been “leaked”. According to Yonhap, the leak included personally identifiable information about KDIC official and non-official cover personnel stationed abroad. The report claimed that the leak was discovered by South Korean authorities a month ago, and that the discovery had resulted in the recall of several KDIC undercover operatives serving overseas “due to concerns over their identities being exposed”.
The Yonhap report claimed that, according to an ongoing probe, the leak may have originated from a personal laptop computer belonging to a civilian KDIC employee. The employee has since claimed that the laptop had been hacked, but some investigators believe the suspect may have “intentionally left the laptop vulnerable to hacking by North Koreans”.
According to an official statement released on Sunday by the Ministry of National Defense, the case is “currently under investigation by military authorities”.

THE INTELLIGENCE CHIEFS OF the United States, Japan and South Korea are to meet behind closed doors this week. The meeting will take place nearly two years after a major diplomatic spat between Japan and South Korea threatened to significantly harm intelligence cooperation between them. In November of 2019, the South Korean government threatened to terminate the General Security of Military Information Agreement (GSOMIA). The agreement was initiated in 2016 under American tutelage, with the aim of facilitating the sharing of intelligence between South Korea and Japan about North Korea’s missile and nuclear programs.
A NORTH KOREAN ACTING ambassador, who is believed to be the son of one of the most senior officials of the ruling Workers’ Party of Korea (WPK), reportedly defected with his family to South Korea, according to sources. Two South Korean news outlets, the Yonhap News Agency and the Maeil Business Newspaper, reported the alleged defection on Monday. They both cited sources in the South Korean government.
A former deputy director of South Korea’s spy agency has been given a prison sentence for diverting funds from the agency’s clandestine operations budget, in order to aid South Korea’s disgraced former President, Lee Myung-bak, who has himself been sentenced to 15 years in prison.
Officials in South Korea and China have cast doubt on rumors circulating in recent days that North Korean Supreme Leader Kim Jong-un may be dead or close to dying. The rumors about Kim’s demise began to circulate on April 15, when the North Korean leader failed to participate at an official ceremony held to mark the birthday of his grandfather. Known as the Day of the Sun —a public holiday in North Korea— the annual event commemorates the birth of the country’s founder, Kim il-Sung.
South Korea appears determined to reject calls from the United States to maintain an intelligence-sharing agreement with Japan, as relations between Seoul, Tokyo and Washington continue to experience tensions. The South Korean government has been issuing warnings since August that it will
South Korea has formally terminated an intelligence-sharing agreement with Japan, as relations between the two countries have reached their lowest point since they formally recognized each other in 1965. Seoul’s decision is the latest move in a tit-for-tad row sparked by the use of forced Korean labor by Japan in World War II. South Korea is demanding financial compensation for the use of slave labor, including sex slaves, by Japanese occupation troops during Korea’s annexation by Japan from 1910 until 1945. Last month, Tokyo responded to a mass boycott of Japanese goods by South Korean consumers by limiting the export of electronics to be used in South Korea’s ship-building industry. A few days ago, Tokyo also removed South Korea from the list of countries with the ability to fast-track their exports to Japan.






South Korean court upholds sentence for university professor convicted of espionage

The convicted agent, identified only as “Qing”, was reportedly spotted and recruited by an espionage cell, referred to as “Ken Jake”, which was led by Chinese Chief Case Officer Liu Nannan whilst completing his PhD in Taiwan. The cell’s primary focus was the collection of high-value secrets from South Korea and Taiwan, through human intelligence (HUMINT) targeting. Investigators stated that the intelligence “Qing” collected included details on the American THAAD (Terminal High Altitude Area Defense) mobile missile defense system, US-South Korea joint military exercise plans, Taiwan-related activities, and the location of a South Korean Navy vessel.
“Qing” operated between May 2024 and March 2025, using social media to approach and offer cash payments to soldiers. He also employed espionage equipment—including a camera hidden in a wristwatch—to evade face-to-face meetings while transferring stolen material. “Qing” also made several trips to South Korea’s Jeju Island to establish a dead-drop infrastructure for facilitating physical intelligence exchanges. He also met with individuals he believed were recruited military assets. The spy cell recruited Navy Corporal Jung Da-jung and Choi Hong-jae, a military conscript who reportedly received ₩ 7.1 million (about US $5,100) in exchange for providing military intelligence information. “Qing” also allegedly infiltrated anti-China/pro-Taiwan independence groups and attempted to gain close access to an unnamed female Taiwanese politician.
Following an undercover investigation by the South Korean Defense Counterintelligence Command (DCC), Qing was arrested in March 2025 by South Korean authorities while carrying out a dead-drop exchange on Jeju Island. DCC Lead Investigator Bang Tu-Cheol posed as an active-duty military asset and built credibility and trust through feeding fake documents to “Qing”. This eventually led to “Qing” meeting Bang on Jeju Island. The operation uncovered a broader network vulnerability when Chinese intelligence reportedly sent material obtained from Choi to Bang for cross-verification. South Korean investigators identified a technical link to Chinese-language file-sharing infrastructure, which allowed them to connect previously separate espionage cases. This discovery helped expose the wider “Ken Jake” cell.
