Japanese electronics giant Casio has revealed that the recent cyberattack was carried out by a ransomware group and confirmed that the incident has resulted in a data breach.
Casio said last week that it had detected unauthorized access to its network on October 5. The incident resulted in a system failure and some service disruptions.
In an update shared on its website on Friday, the company said the incident was the result of a ransomware attack that involved hackers obtaining personal information, as well as confidential files belonging to the company and its affiliates.
While Casio’s investigation into the data breach is ongoing, it has determined to date that the compromised information could include personal and other information on employees, the personal information of business partners, information on individuals who applied for a job, and information on some customers.
The data breach also impacts information related to contracts, invoices, and sales, as well as internal legal, financial, HR, audit, sales, and technical documents.
The ransomware group named Underground, which has been around since at least July 2023, has taken credit for the attack, claiming to have stolen over 200 GB worth of files from Casio systems.
The cybercriminals claim to have obtained legal documents, employee personal and payroll information, NDAs, patents, financial documents, projects, and other confidential files.
The hackers have started leaking the stolen data, which indicates that Casio has refused to pay a ransom.

Indeed, Casio has confirmed a data leak, urging people to refrain from spreading the stolen information “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”.
“In the event of the sending of spam emails or related fake information, slander against those who have been the targets of the leaked information, employees of the Company and its affiliated companies, or other nuisance behavior, we will work closely with the police to respond strictly, protect the privacy and safety of all those involved, and strive to minimize secondary damage,” Casio said.
