The RGB is regarded as North Korea's primary intelligence and clandestine operations organ.[4] Although its original missions have traditionally focused on clandestine operations such as commando raids, infiltrations and disruptions, the RGB has since come to control most of the known North Korean cyber capabilities, mainly under Bureau 121 or its speculated successor, the Cyber Warfare Guidance Bureau.[4]
It was headed at one time by Kim Yong-chol as the first head of the RGB.[5][6]
The RGB was established in 2009 to consolidate various intelligence and special operations agencies of the North Korean government, meaning that units previously tasked with "political warfare, foreign intelligence, propaganda, subversion, kidnapping, special operations, and assassinations" were merged into one single organization.[11]
In August 2010, an RGB agent posing as a defector was caught by South Korean police for planning to assassinate Hwang Jang-yop, who had defected from North Korea in 1997. The previous month two North Korean spies had been imprisoned for plotting to murder Hwang.[12] North Korea denied involvement, but the later defector "Kim Kuk-song" said that he had personally directed the July 2010 operation.[13] "Kim" also said "I can tell you that North Korean operatives are playing an active role in various civil society organisations as well as important institutions in South Korea.".[13]
A defector, a former senior colonel known by the pseudonym Kim Kuk-song, whose identity has been verified by the BBC, had a senior position in the RGB until 2014, and revealed much information about the Bureau's activities in a 2021 interview with the BBC.[13]
On October 31, 2017, two suspects were arrested by Public Security police in Beijing in an attempt to assassinate Kim Han-sol.[14] They were part of a seven-man team sent by the RGB.[15]
On November 12, 2021, an alleged RGB agent led an operation in Japan to illegally obtain foreign currency to shore up the North Korean economy by ordering two South Korean nationals to conduct a business that was against their official status of residence.[16]
On February 15, 2022, an upcoming UN report mentions that the RGB is involved in running several service-related industries throughout Cambodia.[17]
The foundations for North Korean cyber operations were built in the 1990s, after North Korean computer scientists returned from travel abroad proposing to use the Internet as a means to spy on enemies and attack militarily superior opponents such as the United States and South Korea. Subsequently, students were sent abroad to China to participate in top computer science programs.[18]
The cyberwarfare unit was elevated to top priority in 2003 following the US invasion of Iraq.[18]
Reconnaissance missions are also partially overseen by the General Staff Department (GSD) of the Korean People's Army (KPA). As of 2014, experts argued that "North Korea does not seem to have yet organized these units into an overarching Cyber Command."[11]
Until 2017, many North Korean spies were arrested in South Korea. But far fewer were arrested in the following years, apparently as the North started using new technologies rather than old-fashioned spying. In particular, high-profile defectors warned that Pyongyang had created a body of 6,000 skilled hackers.[13]
