Nissho Electric Manufacturing Co., Ltd. Data Breach

Nissho Electric Manufacturing Co., Ltd., a Japanese company specializing in electrical components for the manufacturing sector, was identified as a victim by the Qilin ransomware group on September 28, 2026. This listing was observed through SOCRadar’s Dark Web Monitoring capabilities. The nature of Nissho Electric’s business, particularly its role in industrial supply chains, potentially makes it an attractive target for ransomware operations. The Qilin ransomware group has been exceptionally active, claiming 249 other victims in the preceding 60 days, positioning them as one of the most prolific groups currently tracked. The manufacturing sector represents a significant portion of Qilin’s targets, accounting for nearly a quarter of all reported incidents. Geographically, the United States, Germany, and the United Kingdom are the most frequently targeted countries, with a notable and consistent pattern of targeting Japanese entities. Recent Qilin listings have included companies like SKLG, IKEGAMI TSUSHINKI COMPANY LIMITED, Mitsuwa Trading Co., Ltd, and ASCII Group, all of which overlap with Nissho Electric’s sector and geographic profile, indicating a potential focused campaign.

A stealer-log query was performed against the domain nisshodenki[.]com. The query returned no records, which indicates that no credentials associated with this specific domain were found in the queried dataset. However, the absence of returned records does not definitively confirm that the organization is unaffected. It is possible that credentials may exist under alternate corporate domains, within personal email aliases used for business purposes, or on third-party industrial procurement portals not covered by this specific query. Therefore, “null” in this context means no confirmed signal was detected by this particular scan. The potential for infostealer-harvested credentials to support ransomware operations remains a significant concern. If compromised credentials exist, they could provide threat actors with initial access to corporate networks, potentially through compromised Microsoft 365 accounts, VPNs, or other remote-access portals. Such access could then be leveraged for further reconnaissance, lateral movement, and ultimately, ransomware deployment. The specific targeting of Japanese industrial manufacturers by Qilin, as seen with Nissho Electric and other recent victims, suggests a strategic focus. Given the observed pattern of Qilin targeting Japanese industrial entities, it is recommended to continue monitoring the domain nisshodenki[.]com for any future Qilin activity. A comprehensive credential audit across all corporate email and remote-access systems is advisable. Furthermore, other organizations operating within the same sector and geographic region should consider this incident a shared threat indicator, prompting a review of their own security posture and monitoring capabilities.
