From BBC News:
“South Korea’s military cyber command, set up to guard against hacking, appears to have been breached by North Korea, the military has said.
A spokesman told the BBC that classified information was thought to have been stolen, although it is not clear exactly what data was accessed.
The North has previously been accused of hacking into banks and media outlets but never the South’s military.
Pyongyang has in the past rejected allegations of cyber crime involvement.”
