Japanese tech giant Casio recently experienced a cyberattack on October 5, when an unauthorized individual accessed its internal networks, leading to disruptions in some of its services.

The breach was confirmed by Casio Computer, the parent company behind the iconic Casio brand, recognized for its watches, calculators, musical instruments, cameras, and other electronic products.

"Casio Computer Co., Ltd. has confirmed that on October 5, its network was accessed by an unauthorized third party," the company revealed in a statement today. Following an internal review, the company discovered the unauthorized access led to system disruptions, which have caused some services to be temporarily unavailable. Casio mentioned it cannot provide further details at this stage, as investigations are still ongoing. The company is working closely with external specialists to assess whether personal data or confidential information was compromised during the attack.

Although the breach has disrupted services, Casio has yet to specify which services have been impacted.

The company reported the cyber incident to the relevant data protection authorities and quickly implemented measures to prevent further unauthorized access. BleepingComputer reached out to Casio for more information, but a response has not yet been provided.

So far, no ransomware group has claimed responsibility for the attack on Casio.

This attack comes nearly a year after a previous data breach involving Casio's ClassPad education platform, which exposed customer data from 149 countries, including names, email addresses, and other personal information.

The recent cyberattack adds to the company's challenges, as Casio recently informed shareholders of an expected $50 million financial loss due to significant personnel restructuring.
