This is interesting. Apparently the mystery cyber attack that shut down a range of South Korean banks and crippled parts of its media also hit a US-based North Korean human rights group. Suspicions obviously turn to Pyongyang, particularly after its earlier claims that it was the target of a US/South Korean cyberattack. Of course, if a country besides North Korea wanted to test its offensive cyber capabilities, also attacking organizations outside of South Korea would be a good way of covering their tracks. At this point the forensics would focus on where the attack came from. That’s why all the stories at this point are about suspicions.
