North Korea: Games the DPRK Plays

North Korea is shuffling the missiles of April, The Japan Times reports in "North Korea sows confusion over launch":

North Korea has been repeatedly moving multiple missiles around in an apparent bid to confuse outside intelligence gatherers ahead of an expected launch, Yonhap reported Thursday.

Musudan Missiles

According to intelligence analysis cited by the South Korean news agency, two midrange Musudan missiles have been repeatedly moved in and out of a warehouse facility in the eastern port city of Wonsan.

At the same time, at least five mobile launch vehicles have also been spotted swapping positions in South Hamgyeong Province. They are believed to be launch platforms for short-range Scud missiles, which have a range of 300 to 500 km, and medium-range Nodong missiles, which can travel 1,300 to 1,500

km.

“There are signs the North could fire off Musudan missiles any time soon,” an intelligence source said. “But the North has been repeatedly moving its missiles in and out of a shed, which needs close monitoring.”

Nodong

Another source suggested Pyongyang was hoping to “fatigue” South Korean and U.S. intelligence gatherers who have been on a heightened state of surveillance alert since Wednesday.

In addition, the South Korean government has verified hacking done by the NORKs, as reported by Yonhap in "Gov't confirms Pyongyang link in March cyber attacks":

Amid escalating tension on the Korean Peninsula, the South Korean government on Wednesday announced that North Korea was behind the massive hacking attack that paralyzed networks of local financial firms and broadcasters last month.

The March 20 incident marks the latest attack in Pyongyang's growing pursuit of technological warfare. While the communist state has denied allegations, it has been blamed for a series of cyber attacks on the Web sites of South Korean government agencies and financial institutions in the past few years.

North Korea is known to operate a cyber warfare unit of 3,000 elite hackers who are trained to break into computer networks to steal information and distribute malware.
