Background on the Ransomware Attack
On October 5, a ransomware attack targeting Japanese electronics giant Casio affected millions of its systems, leading to the compromise of sensitive personal data. The attack was attributed to the Underground ransomware gang, which claimed responsibility for stealing over 200 gigabytes of information from Casio’s infrastructure.
Update from Casio Regarding the Breach
Casio has issued an official update confirming the extent of the cyberattack and its impact on the company’s operations. The company acknowledges that it has been working to address the issue as comprehensively as possible, but some internal documents, including personal data, have been leaked.
Affected Individuals
The breach has impacted approximately 8,500 individuals, including employees, business partners, and customers of Casio. Personal data compromised includes but is not limited to names, employee numbers, email addresses, phone numbers, and ID card information. Additionally, the sensitive data of more than 1,900 Casio business partners and over 91 customers has been exposed. Notably, no credit card or payment information was accessed during the attack, as Casio’s systems for handling customer personal data were unaffected.
The Nature of the Ransomware Attack
The hackers exploited phishing tactics to gain access to Casio’s network, citing "deficiencies in the company’s measures against phishing emails" as a potential reason for the breach. According to Casio spokesperson Ayuko Hara, the company did not negotiate with the ransomware group responsible for the unauthorized access and emphasized that it has "not responded to any requests from malicious actors."
Response from Experts
Cybersecurity experts have expressed concern over the sophistication of the attack and its potential implications. David Pescatello, a cybersecurity analyst at Flipp Press Release Management, commented on the targeted nature of the breach and suggested that such incidents highlight the importance of robust cybersecurity measures to protect sensitive data.
