Casio, a major Japanese electronics manufacturing corporation, has acknowledged that personal and secret information was compromised as a result of a ransomware incident earlier this month after the Underground ransomware operation accepted credit for the intrusion.
Last week, Casio announced that it had discovered unauthorized network access on October 5. The incident led to a system breakdown and some service disruptions.
The Underground ransomware group said in a post on its dark web claimed credit for the attack, exposing a number of papers supposedly taken from the Japanese tech giant’s computers.
The cybercriminals claim to have gotten legal documents, employee personal and payroll information, non-disclosure agreements, patents, financial data, projects, and other confidential material.
While Casio’s investigation into the data breach continues, it has determined that the compromised information may include personal and other information on employees, personal information on business partners, information on job applicants, and information on some customers.
Casio also lost invoice and sales transaction data, as well as other documents containing legal, human resource planning, financial, audit, sales, and technical information as a result of the event.
However, neither credit card information nor its service systems were compromised, according to Casio, which cautioned against sharing exposed information online while an investigation is ongoing.
“Please refrain from spreading this information through social media, etc., as it could increase the damage caused by the leak of information on this case, violate the privacy of those affected, have serious effects on their lives and businesses, and encourage crime,” said Casio.
We earlier reported that one of the biggest telecom providers in the United States, Comcast, has revealed that a ransomware attack on Financial Business and Consumer Solutions (FBCS), a third-party debt collection service provider, exposed the personal data of around 238,000 customers.
