200GB of Data Stolen in Casio Cyberattack, Hackers Claim

The major Japanese company Casio is still recovering from a ransomware attack that occurred nearly two weeks ago. Ayuko Hara, a company representative, told the tech publication TechCrunch that the prospects for full recovery remain uncertain.

“Since October 5, our servers experienced a system failure that rendered several of them unusable,” Hara reported. Following this, Casio shut down its systems to prevent further damage from spreading.

These measures impacted order and supply processes, particularly in the domestic market. Customers in Japan are greeted with the message: “Due to delivery system issues, shipping times are currently undefined.” However, Casio’s global website is operating as normal at the time of publication.

A week after the attack, the company confirmed that its systems had fallen victim to ransomware, resulting in the compromise of sensitive data. The hacker group Underground claimed responsibility for the attack and posted samples of the stolen information on its dark website.

Hara noted that the attackers left a threatening message indicating their intention to publish the stolen data, though Casio reportedly has not received a ransom demand. The representative declined to comment on the company’s next steps or any contact with the criminals.

The investigation is ongoing, and the exact extent of the data breach has yet to be determined. Nevertheless, the hackers claim to have stolen over 200 gigabytes of data. The only piece of good news is that, according to the company, Casio’s customers’ credit card information was not compromised.
