What the group claims

In 2022, Fukoku Co., Ltd. celebrates its 90th anniversary.Since our founder, Shinkichi Koga, began manufacturing and selling futons in Yanagawa City, Fukuoka Prefecture, Fukoku has consistently been of service to our customers through "textiles."Today, we enjoy patronage from a wide range of industries, from futons (bedding) to the automotive, housing, and nursing care fields, but all of this is a business that derives from the "textile = thread" that we have known since our founding.In 2009, we created a new brand logo,which is "CCC Chasic."• Date bases. accounting. sales. purchasing. drawings. prototypes. production cycles. https://fukoku-jp.com/

Disclosure context

About Spacebears

Spacebears is a recently emerged ransomware group first observed in April 2024, operating with apparent financial motivations and demonstrating a broad targeting approach across multiple sectors and geographic regions. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their targeting pattern suggests a professional operation focused on maximizing financial returns rather than geopolitical objectives. With 117 known victims since their emergence, Spacebears has shown particular focus on organizations in the United States, Germany, Spain, Italy, and Canada, with their attacks primarily affecting technology, healthcare, manufacturing, and business services sectors, indicating they likely employ opportunistic targeting rather than sector-specific specialization. Their attack methodology, initial access vectors, and specific technical capabilities have not been extensively documented in public reporting from major cybersecurity firms or law enforcement agencies, limiting detailed analysis of their operational procedures and tools. Due to the group's recent emergence and limited public intelligence reporting, notable high-profile campaigns and specific victim details remain largely undocumented in established threat intelligence channels. The group's current operational status appears active given their recent emergence timeline, though comprehensive analysis is constrained by the lack of detailed public reporting from authoritative cybersecurity sources. The group has been linked to 185 public disclosures across our corpus. First observed on a leak site on April 29, 2024; most recent post July 13, 2026. The operation is currently active.

If your organisation is affected

A listing by Spacebears means Fukoku Co. Ltd. appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, JPCERT/CC (Japan), as required for your jurisdiction.
Monitor for the data appearing on Spacebears's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim.
