The National Intelligence Service (NIS) under the Lee Myung-bak government told a senior prosecutor investigating former President Roh Moo-hyun to leak information about Roh receiving an expensive watch to the press to humiliate the former president. It was confirmed that the NIS conducted a project to support conservative groups by connecting them to public and private businesses. On October 23, the National Intelligence Service reform committee received a report of the investigation results by the task force overseeing the eradication of long-established irregularities and recommended that the government request a prosecutors' investigation.

As for the alleged involvement in the investigation of former President Roh, the NIS reform committee confirmed that former NIS director, Won Sei-hoon received a report including plans to "highlight former President Roh's double standards and the necessity for an investigation that knows no sanctuary on and offline to prevent the spread of public opinion sympathetic to the former president" in internal NIS meetings on April 19 and 20, 2009. One senior official who was a close aide to Won met with Lee In-kyu, the head of the Central Investigation Division at the Supreme Prosecutors' Office at the time, on April 21 and suggested an investigation without detaining the former president. At the same time, he said, "Since the receiving of an expensive watch is not an important issue, leak the information to the press and use it to disgrace him somewhat. We think it would be appropriate to carry out the investigation without detaining him."

The task force also confirmed that NIS agents personally requested cooperation from the press. According to former director Won's instructions to "highlight the double standards of former President Roh Moo-hyun" in April 2009, four NIS agents including the official overseeing the press in the Domestic Intelligence Division contacted the president of SBS and asked that the broadcasting company actively cover the investigation on former President Roh. The agent in charge of KBS requested cooperation from KBS asking them not to cover the Chosun Ilbo article on the intelligence service's alleged involvement in the investigation published on May 7, 2009. It was revealed that the NIS also delivered 2 million won in cash to Ko Dae-young, the director of the KBS newsroom at the time.

The intelligence service drew up plans to foster conservative organizations to strengthen their role in fighting left-wing groups and stopping them from interfering with state administration and from devising pro-North schemes, upon request from the secretary for civil society at Cheong Wa Dae's Office of the Senior Secretary for Political Affairs in 2009. They started by supporting conservative groups through public corporations in 2009, then expanded the project by including private corporations in 2010. In 2011, they included online media outlets among those subject for the support and continued to expand the project.

On April 14, 2009, the secretary for civil society asked the National Intelligence Service to block the funding of left-wing groups by the five public enterprises and to redirect the contribution and advertisements to 27 conservative groups and 12 Internet media outlets that they selected, and Won ordered the Domestic Intelligence Division to carry out the request.

In 2010, they expanded the project from existing public enterprises to the Federation of Korean Industries (FKI) and large businesses. The NIS reform committee announced, "We confirmed that the intelligence service's leadership received frequent reports year round on how eighteen conservative groups were matched with seventeen companies and received over 3.2 billion won in funding." The NIS divided the organizations into different grades and funded them according to their categories. Three groups including the Korea Freedom Federation were categorized as grade-S, five groups including Mediawatch grade-A, four groups including the National Action Campaign for Freedom and Democracy in Korea grade-B, four groups including the Hansun Foundation grade-C, and two groups including Zeitgeist (Sidaejeongsin) grade-D. Companies, both public and private, were forced to fund the conservative groups including the Federation of Korean Industries, Samsung, Hyundai Motor Company, LG, SK, Hanwha, Lotte, Hanjin, Doosan, Hyundai Heavy Industries, GS, LH Corporation, K-water, Korea Hydro & Nuclear Power, Korea Expressway Corporation, Korea National Oil Corporation, and the Korea Development Bank.

The latest investigation also confirmed that the senior officials at the intelligence service received frequent reports throughout the year on how forty-three conservative organizations (including seven online media outlets) received over 3.6 billion won in funding in the form of donations and advertisement contracts from eighteen companies including FKI (with the exception of public corporations) in 2011.

In 2012, the intelligence service also drew up plans to match companies with conservative groups to provide over 5 billion won in funding, but the project was abruptly ended with important political events including two major elections beginning in the second half of the year, along with the online comment controversy.

As for the intelligence service's alleged monitoring of civilians using the hacking program RCS created by an Italian hacking team, the NIS reform committee collected data from the computers and cell phones of a total of 213 people related to international crime and terrorist groups based on a review of RCS servers. However, the reform committee said that the data gathered were all linked to people with alleged connections to North Korea, terrorist groups, and international crime.

As for the intelligence service's involvement in the leaking of the personal information of Chae Dong-wook, former public prosecutor general, the reform committee was not able to uncover meaningful statements or facts other than the statement that the NIS agent Song had given during the trial.
