The company said affected customers were contacted separately. Its July 9, 2024 investigation notice did not publish an affected-person total or list the specific data fields.
What happened in the Fujitsu incident?
The incident was malware activity on Fujitsu internal business PCs, not a publicly reported breach of a Fujitsu customer service. Fujitsu first disclosed the issue on March 15, 2024, saying malware had been found on multiple PCs and that files containing personal or customer-related information might have been vulnerable to unauthorized removal. The investigation was ongoing then, and Fujitsu said it had received no misuse reports at that point. Fujitsu’s March 15 notice
On July 9, 2024, Fujitsu published its investigation results. It said it confirmed 49 business PCs with malware infection or related copy-command and file-transfer activity. All were used on Fujitsu’s internal network in Japan; the company said it found no impact on business PCs in network environments outside Japan. Fujitsu’s July 9 investigation notice
The figure of 49 refers to computers, not affected people or customers. Fujitsu said it found no additional affected PCs beyond those initially detected.

What personal or customer information was involved?
Fujitsu said some files that may have been taken contained personal information about some people or information related to certain customers’ business. The company did not publish a total number of people affected or enumerate the information fields in its July 9 notice. It said affected customers were informed separately and that necessary actions were being taken. Fujitsu’s July 9 investigation notice
The wording matters: Fujitsu said files may have been fraudulently removed. That is not the same as confirming that every potentially exposed file was copied or that all customer or personal information was taken.
Were Fujitsu customer services or customer networks accessed?
Fujitsu said the implicated computers were not used to manage cloud services it provides to customers. Its investigation found no trace of access to customer-facing services and concluded that the incident had not spread beyond company business computers, including into customer network environments. Those are Fujitsu’s findings, rather than an independently published account of the investigation. Fujitsu’s July 9 investigation notice
Did Fujitsu report misuse of the information?
As of its July 9, 2024 notice, Fujitsu said it had received no reports of misuse. Its statement was time-specific: “At present, Fujitsu has not received any reports of misuse of personal or information related to customer’s business.” Fujitsu’s July 9 investigation notice

No. The 2024 malware event involved Fujitsu’s internal business PCs. It is distinct from both the 2021 incident involving a Fujitsu-managed project-information-sharing tool and the separate 2024 MICJET/Takamatsu certificate misdelivery matter.
For context only, Japan’s transport ministry reported approximately 76,000 email addresses in connection with the separate 2021 project-tool incident. That number does not describe the 2024 internal-PC malware event. Japan’s transport ministry report on the 2021 incident Fujitsu Japan’s notice about the separate Takamatsu matter is available here.
