What Symantec research into Buckeye using Shadow Brokers Leaked tools before they where leaked actually means
Symantec posted an article on May 6th under the title (Buckeye: Espionage Outfit Used Equation Group Tools Prior to Shadow Brokers Leak) that was taken out of context in most news publications including the New York Times.
This research shows that at some point the China government got a copy of the same tools that where exposed from the NSA by the group Shadow Brokers.
