Troves of data were stolen from the company.
Casio was compromised last week in an ‘unauthorised access’ incident in which masses of data were stolen.
According to The Record, the intrusion which saw the exfiltration of troves of data, including confidential, financial, and legal documents, employees' personal and payroll data, non-disclosure agreements, patent and project information, and incident reports purportedly stolen from Casio's systems.
The company said in a statement that it is “currently investigating the details, and an external specialist agency is also investigating to confirm whether any personal information or other important information has been leaked”.
The company said the unauthorised access had caused a system failure, resulting in the inability to provide some services.
Casio said 91,921 “items” belonging to customers in Japan were leaked, while 35,049 items belonging to customers from other countries were exposed. The company did not clarify what they classified as an “item.”
