"I'll show you what we found." 

He shows us what was inside a recently 5discovered North Korean internet server. 

"There's 6a bunch of working files in here." 

Files including sketches and video from North Korea, which 7resemble the animation from two shows 8produced and streamed by American companies. Amazon's "Invincible" and another coming soon called "Iyanu: Child of Wonder", set to stream on Max, which along with CNN, is owned by Warner Brothers Discovery. There's no 9evidence that the studios knew that any 10proprietary work was on a North Korean server. 

"At some stage in this production process, these files appear to be being worked on by the North Korean."

There's a clip of "Iyanu", which hasn't been 11released yet. Williams says a lot of American production work is 12outsourced, particularly to China, where it could then be 13subcontracted to North Koreans without the American company's 14awareness. 

"It's very common. Numerous Chinese companies have been 15sanctioned by the U.S. for working with North Korea, not just in animation, but in other areas as well. 

A draft of one animation has Chinese instructions translated into Korean. There's also this production sheet in English for "Invincible". 

"Is there any evidence that the American studios knew about this?" 

"We didn't find any evidence that they had any direct knowledge of any of this. We found the names of some animations, we found the names of some U.S. companies, but nothing that 16concretely tied that back to the U.S. companies."
