Casio Computer Co., Ltd., the renowned Japanese electronics manufacturer, publicly acknowledged a serious security breach on Saturday, revealing that a recent ransomware attack impacted their network and compromised sensitive data. This admission followed a claim from the Underground ransomware group, which announced responsibility for the attack on October 10, 2024, after purportedly leaking stolen data on its dark web portal.
On October 5, 2024, Casio experienced significant system failures across some servers. Upon investigation, the company discovered indications of unauthorized access, leading to substantial disruptions in service provision. "The preliminary findings indicate a cyberattack utilizing ransomware, prompting us to shut down affected servers on both our internet and internal networks," said a company representative during a press briefing on the incident.

In an effort to confront the breach, Casio engaged with an external cybersecurity specialist to conduct an in-depth forensic investigation. The company's proactive measures included the formation of a task force to restore operations and secure affected internal systems.
Casio promptly notified law enforcement on October 6 and communicated with the Personal Information Protection Commission on October 7. They further escalated the situation by formally reporting the matter by October 9, showcasing their commitment to transparency and accountability.
While the full extent of the damage is still being evaluated, Casio indicated that the leaked data encompasses a range of sensitive information. This includes, but is not limited to, internal documents related to legal, financial, and human resources planning, as well as audit and sales information from the company and its affiliates. "The integrity of our business and our partners is paramount, and we are doing everything in our power to address this situation comprehensively," the spokesperson remarked.

Specifically noted in their disclosure was that some customer data might have been compromised. "It includes information about customers utilizing services from us and our affiliates, as well as personal data of individuals who previously interviewed for employment with us," the notice detailed. However, they clarified, "No credit card or other payment information was accessed, as this data is not stored in our database."

Services like CASIO ID and ClassPad.net were fortunate to remain unaffected due to operating on separate servers from the one breached. Nevertheless, Casio urged customers to remain vigilant in light of the incident. "Please be aware that there is a possibility that your personal information may be misused to send you unsolicited e-mails such as phishing e-mails or spam e-mails. If you receive any suspicious e-mails, please do not open them and delete them immediately," advised the company.
Impact and Legacy
In addition to safeguarding their own interests, Casio emphasized the importance of cooperation in managing the fallout from this incident. They requested that individuals avoid sharing any leaked information on social media or other platforms, warning that doing so could exacerbate the situation and violate the privacy of those affected. "Please refrain from spreading this information through social media, as it could increase the damage caused by the leak of information, violate the privacy of those impacted, and potentially encourage further criminal activity," the company implored.
