Russian cyber criminals have claimed the cyber attack on Japanese technology multinational company Casio.
In a statement on its website, the company said it detected unauthorised activity on its network on 5 October, which resulted in a system failure.
While the threat actor behind the incident was initially unknown, the Russian threat group Underground, which appeared for the first time only a few months ago, claimed the incident on its dark web leak site.
The threat group allegedly stole 204.9 gigabytes of data, including confidential documents, legal documents, personal employee data, confidential non-disclosure agreements, employee payroll, patent information, company financial documents, project information and “incidents”.
Additionally, while the group is reportedly a ransomware group, the data appears to have been published and is available for free download, suggesting that either negotiations fell through or the incident was not a ransomware attack in the first place.
As Cyber Daily reported yesterday (10 October), Casio is aware of the incident and is currently investigating.
“Casio Computer Co., Ltd. confirmed that its network had been illegally accessed by a third party on October 5th of this year,” the company said in a statement translated from Japanese.
“After conducting an internal investigation, it was determined that the unauthorised access had caused a system failure, resulting in the inability to provide some services.”
The company added that it has launched an investigation into the breach to determine if any data has been accessed or compromised.
“We are currently investigating the details, and an external specialist agency is also investigating to confirm whether any personal information or other important information has been leaked,” it said.
“After becoming aware of the unauthorised access, we promptly reported it to the relevant authorities and have implemented measures such as restricting access from outside.
“We deeply apologise for causing great concern and inconvenience to all those involved.”
Cyber Daily is currently awaiting additional commentary from Casio.
