From:  The FBI’s North Korea evidence is nonsense 

The reason it’s nonsense is that the hacker underground shares code. They share everything: tools, techniques, exploits, owned-systems, botnets, and infrastructure. Different groups even share members. It is implausible that North Korea would develop it’s own malware from scratch.

As a fan of author Tom Clancy’s early works I found this quote funny.  From: Researcher: Sony Hack Was Likely an Inside Job by a Woman Named “Lena”
