A weekly reported late in 2009 that progressive personages are under intensive surveillance by IS, and then IS director Won Se Hun ordered his inferiors to find the one behind the leakage of inside information.

On his instructions, IS agents who had been involved in the operation for watching heavyweights and civilians of south Korea reportedly secured in secrecy private information of the director and chief editor and other leading officials of the weekly and hacked their cell phone messages.

Many innocent people fell victim to IS illegal surveillance and investigation.

Disclosing the above-said facts, MBC said that IS acted as Won's private detachment.
