This group also have support from the Chinese hackers group and many the times they performed many operations together.
From the research in this 1 week since the attack it is only assumed that North Korea is behind this cyber-attack. Google researcher Neel Mehta found out that coding style of this attack is very similar to previous cyber-attack which was done from the North before. Kaspersky Labs also hinted that it might be North Korea behind this global attack as the way of coding of Lazarus and WannaCry is very similar to each other. North Korea has always been supporting and defending their cyber criminals. So there is no wonder that the North Korea Government secretly supporting and defending this global cyber crisis too.
