North Koreans hacked Sony Pix?

Kurt Baumgartner has published the blog post, describing similarities between Destover wiper (used in the Sonny attack), Shamoon wiper (used to attack the Saudi Aramco in Saudi Arabia and the Rasgas company in Qatar in2012) and the DarkSeoul attacks against several banks and media companies in Seoul, South Korea in 2013.

“The above list of commonalities does not, of course, prove that the crew behind Shamoon is the same as the crew behind both DarkSeoul and Destover. But it should be noted that the reactionary events and the groups' operational and toolset characteristics all carry marked similarities. And, it is extraordinary that such unusual and focused acts of large scale cyber-destruction are being carried out with clearly recognizable similarities.”

The evidence suggests that hackers from North Korea are behind the attack on Sony.
