Japanese technology giant Fujitsu on Friday confirmed that it fell victim to a cyberattack that likely resulted in the theft of personal and customer information.
According to the company, it discovered that multiple work computers within its environment were infected with malware and disconnected them from the network.
Furthermore, Fujitsu said in an incident notification written in Japanse, the investigation into the attack has revealed that files containing personal information and customer information were likely stolen.
“After confirming the presence of malware, we immediately disconnected the affected business computers and took measures such as strengthening monitoring of other business computers,” a translation of the incident notification reads.
The company continues to investigate how the malware infection occurred and whether data has been leaked.
Fujitsu also says that it has informed the relevant national authorities of the attack and that it has started notifying the potentially affected individuals and customers.
“To date, we have not received any reports that personal information or information about our customers has been misused,” the company says.
Fujitsu did not share details on the type of malware attack it fell victim to, but ransomware might have been involved. The typical response to ransomware is to disconnect systems to contain the incident and data theft is encountered in most ransomware incidents.
The company has yet to reveal what type of personal information was stolen and how many people might have been affected, and whether the breach is limited to its Japanese offices.
SecurityWeek has contacted Fujitsu for additional details on the cyberattack and will update this article as soon as a reply arrives.
In 2021, several Japanese government entities disclosed impact from a data breach involving Fujitsu ProjectWEB, a tool for sharing data within and outside business environments. Fujitsu eventually retired the vulnerable tool.
