The BlackSuit ransomware gang claims Responsibility For Kadokawa ransomware attack

The BlackSuit ransomware gang is claiming responsibility for a June 8th cyberattack on Kadokawa Corporation, threatening to publish stolen data unless a ransom is paid. The gang has set a deadline of July 1st for the ransom, warning that the released data will include contacts, confidential documents, employee data, business plans, and financial data.

Kadokawa Corporation is a major Japanese media conglomerate involved in film, publishing, and gaming, including the well-known game developer FromSoftware. The company reported net sales of approximately $1.6 Billion USD in 2023. The cyberattack caused service outages across multiple Kadokawa Group websites, significantly disrupting the company’s operations as they share the same data center. This attack particularly affected the popular Japanese video-sharing platform Niconico.

“In response to the system failure, Kadokawa is working on building a secure network and server environment,” explained the Wednesday update.

“Its top priority is to restore the accounting functions, which are fundamental to its business activities, and to normalize the manufacturing and distribution functions in the publication business, which generate considerable revenue. The accounting functions, owing partly to measures in an analog manner, are expected to be restored in early July.”

BullWall Executive, Carol Volk had this comment:

“As Kadokawa rebuilds its systems, focusing on the protective aspects of ransomware containment is crucial. A robust ransomware containment system offers significant benefits over simple Endpoint Detection and Response (EDR) solutions. While EDR is essential for identifying and mitigating threats, a comprehensive ransomware containment system ensures that sensitive data remains secure even during an attack. This approach not only detects but also isolates and neutralizes threats”

Cigent CGO Brett Hansen follows with this comment:

“Restoring critical functions and rebuilding the network is table stakes after a major attack and fortifying against similar threats. That said, it is more a matter of protection, than detection to ensure data remains safe during an attack. When data is protected at rest, it can remain safe during an attack. There are multiple ways to ensure an attacker in-system still cannot steal or encrypt your data. zero-trust, MFA, hidden partitions and encryption are all proven methods of protecting data at rest when properly implemented.”

I wish the company luck in restoring their systems. But in this day and age, you need a plan to keep the bad guys out, and a plan to fix everything if they do get in. I am not sure about the first part of this, but this organization is certainly testing the second part right now.
