Casio reports an IT system failure following a network breach over the weekend

Japanese tech giant Casio suffered a cyberattack after an unauthorized actor accessed its networks on October 5, causing system disruptions that impacted some of its services.

The disclosure comes from Casio Computer, the parent company of the Casio brand, which is widely known for its watches, calculators, musical instruments, cameras and other electronic devices.

“Casio Computer Co., Ltd.” confirmed on October 5th of this year that a third party accessed its network in an unauthorized manner,” said an announcement posted on Casio’s website today.

“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 company says it cannot provide further details to the public while the investigation is ongoing, noting that it is working with an outside specialist to determine whether personal data or other sensitive information was stolen in the attack.

While Casio says the incident is causing service disruptions, it hasn’t specifically specified what will be affected.

Casio says it reported the incident to the relevant data protection authorities and measures to restrict access to external actors were immediately implemented.

BleepingComputer reached out to Casio to learn more about the incident, but comment was not immediately available.

Meanwhile, no ransomware groups have yet claimed responsibility for an attack on Casio.

About a year ago, Casio reported another data breach incident in which hackers managed to gain access to the servers of its education platform ClassPad.

This breach exposed customer data from 149 countries, including names, email addresses, countries of residence, service usage details, purchase information, license codes and order details.

The latest cybersecurity incident comes at a difficult time for Casio, as the company recently informed shareholders that the company will incur extraordinary losses of nearly $50,000,000 due to a major workforce restructuring.
