Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group BlackSuit (formerly Royal) on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

Our team gained access to the Kadokawa network almost a month ago. It took some time, because of the language, to figure out that Kadokawa subsidiaries' networks were connected to each other and to get through all the mess Kadokawa's IT department made there. We have discovered that Kadokawa networks architecture was not organised properly. It was different networks connected to the one big Kadokawas infrastructure being controlled through global control points, such as eSXI and V-sphere. Once we have gained access to the control center we have encrypted the whole network (Dwango, NicoNico, Kadokawa, other subsidiaries).
