Casio Confirms Data Breach Following Ransomware Attack
Japanese electronics giant Casio has confirmed a significant data breach following a ransomware attack that occurred in October 2024. The attack, carried out by the notorious “Underground” ransomware group, compromised the personal information of approximately 8,500 individuals. This includes employees, business partners, and a limited number of customers.
The incident began on October 5th when phishing emails successfully infiltrated Casio’s IT systems, granting the attackers unauthorized access to sensitive data. The attack resulted in disruptions to Casio’s operations and the theft of personal information such as names, contact details, dates of birth, and in some cases, tax identification numbers.
The Underground ransomware group claimed responsibility for the attack on October 10th, demanding a ransom payment to prevent the release of stolen data. However, Casio, following the advice of law enforcement and cybersecurity experts, refused to negotiate with the attackers.
In a public statement, Casio’s Chief Information Officer, Hiroshi Tanaka, expressed regret over the incident:
We deeply regret that this incident has occurred and recognize the distress it has caused to those affected. Protecting the privacy and security of our stakeholders is of the utmost importance to us. We are taking this matter very seriously and are committed to learning from it to prevent future occurrences.
Tanaka also outlined steps the company has taken since the breach, which include upgrading its IT security infrastructure, conducting a comprehensive review of its systems, and providing cybersecurity training to employees to prevent phishing attacks.
The company has been working closely with law enforcement and cybersecurity specialists to investigate the incident and limit potential harm. In addition to issuing personal notifications to impacted individuals, Casio has offered free credit monitoring services for a year to help protect against identity theft.
