Japanese electronics giant Casio Computer Co., Ltd. has disclosed a significant cybersecurity incident involving unauthorized access to its network. The breach, detected on October 5, 2024, resulted in system failures and service disruptions, highlighting the ongoing challenges companies face in securing their digital infrastructure.
In an announcement released today, Casio revealed that the unauthorized access caused widespread system failures, preventing the company from providing some of its services.
"As a result of an internal investigation, it was determined that this unauthorized access caused a system disruption, and some services are currently unavailable."
The full extent of the breach remains under investigation, with Casio enlisting the help of an external specialized organization to determine if any sensitive information, including personal data, has been compromised.
In response to the breach, Casio has implemented immediate mitigation measures, including restricting access from outside its network and notifying relevant organizations.
Notably, this is not the first time Casio has faced cybersecurity challenges. Last year, the company disclosed a data breach incident where hackers gained access to the servers of its ClassPad education platform.
While technical details about the nature of the attack remain scarce, the incident bears hallmarks of increasingly sophisticated cyber operations targeting large corporations. The ability of the attackers to gain unauthorized access and cause system failures suggests a well-orchestrated campaign.
