Seoul: North Korea has changed its secret
communication frequencies or encryption system to prevent
spying by South Korea following the death of its leader Kim
Jong-Il, a report said on Saturday.
Seoul is struggling to gather intelligence following the
changes, which came after the first order given by Kim`s son
and successor Jong-Un was apparently leaked to the South
Korean media, according to the Dong-A Ilbo.
"It appears that the North Korean military is changing
the frequency bandwidth or encryption system out of the fear
that the South Korean military is wiretapping," the South
Korean daily quoted a military intelligence source as saying.
North Korea announced on Monday that Kim Jong-Il had died
of a heart attack two days earlier.
South Korean media have reported that Kim Jong-Un issued
his first order shortly before the death was announced,
instructing troops to halt field exercises and training and
return to their bases.
The order is reported to have been issued in encrypted
code by wireless frequencies to all troops, which the South`s
intelligence service decrypted.
South Korea`s spy agency has come under fire for failing
to learn about his demise before it was officially announced.
But President Lee Myung-Bak has defended his intelligence
chief and rejected opposition calls for him to be sacked.
