Casio has issued a series of updates, including a prior notice on October 8 regarding the unauthorized access and its consequences.

Investigation Findings

Preliminary findings indicate that while Casio has taken considerable steps to enhance its cybersecurity posture in response to a rising wave of cyber threats, gaps in defenses against phishing emails and the security of its global network—including overseas offices—were exploited.

Fortunately, the investigation did not reveal any compromise of customer databases or personal information systems.

However, it has been confirmed that sensitive internal documents containing the personal information of employees and business partners were leaked. The company is diligently working to identify affected individuals and will reach out to them directly.

Personal Information Exposed

The leaked data includes:

• Employee Information: Details of 6,456 individuals, including names, employee numbers, emails, and internal affiliations. A subset of employees had additional personal information such as gender, date of birth, and even family details disclosed.
• Business Partner Data: Information on 1,931 contacts across Casio and its subsidiaries, including names, email addresses, and company details.
• Customer Information: Personal details for 91 customers, specifically related to purchases requiring delivery and installation.

While sensitive internal documents were exposed, Casio clarified that no credit card information or insider-related data was compromised.

In light of this incident, Casio is enhancing its IT security protocols across all operations, especially in its overseas offices.

The company has committed to a thorough review of its information management systems and fortifying employee training regarding cybersecurity practices.

Most services affected by the attack have resumed, although some individual services remain temporarily suspended. Casio has expressed sincere apologies for the disruption faced by its users and stakeholders.

Casio has noted that some employees have received unsolicited spam emails possibly linked to the breach.

The company urges those affected to refrain from sharing sensitive information via social media to mitigate potential secondary damage.

Casio is cooperating closely with authorities to address this issue and to take action against any malicious activities stemming from the incident.

Casio is dedicated to rectifying this breach and ensuring the continued security of its systems. The company reaffirms its commitment to providing reliable products and services while fostering a safe working environment for its employees and partners.

Casio extends its deep apologies for any distress caused by this unfortunate event.
