Casio Confirms Ransomware Attacks and Leak of Confidential Information

Earlier this month, Japanese electronics giant Casio suffered a ransomware attack that led to the theft of personal and confidential data.

The company initially revealed that a cyberattack had led to disruptions in its systems. However, upon further investigation, the company  confirmed it was a ransomware attack .

“On October 5, a system failure occurred on some of our servers, rendering several systems unusable. After investigating the incident, we confirmed that the servers showed signs of unauthorized access,” Casio said. “In response, we requested an outside security specialist to conduct a forensic investigation. On the same day, we took measures to shut down the servers that had suffered unauthorized access from the internet and our internal network, since we suspected a cyber attack using ransomware.”

The stolen information includes sensitive details about employees, job applicants, business partners and customers. Though credit card data was not compromised, the Underground ransomware group exposed and leaked other private information.

Casio's services, such as CASIO ID and ClassPad.net, remain unaffected.

Here’s a list of potentially leaked information, according to the latest Casio update:

• Employee personal information  (including temporary and contract employees)
• Limited personal information belonging to the employees of affiliated companies
• Personal information of Casio’s business partners and some of its affiliated businesses
• Personal information of individuals who participated in previous interviews in the company
• Information about some customers who use services provided by the Company and some affiliated companies (credit card info was not included)
