GS Yuasa Lithium Power Listed by Akira Ransomware Group

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Reported Details of the Breach

Public reporting indicates the incident is a ransomware attack in which Akira gained access to GS Yuasa Lithium Power’s network and removed sensitive corporate files. The number of individuals whose personal data was taken remains unknown. No exact date of initial compromise has been disclosed. The leak site posting explicitly lists categories such as client info, contracts, and technical specifications related to high-profile projects.

Internal files exfiltrated include project data described as “BOEING satellite and other interesting directories.” The attackers have not yet published the full archive but have signaled an imminent release.

Why This Matters for You and Your Family

When a specialized manufacturer like GS Yuasa Lithium Power loses control of contracts, client lists, and technical drawings, the ripple effects reach ordinary people. Employees, contractors, and customers whose names, emails, or contact details appear in those files can face increased phishing, identity theft, and harassment. If your employer or a company you do business with uses these batteries in satellites, defense systems, or industrial equipment, your information may now sit in an attacker’s archive.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
