Runtec Listed by Lynx Ransomware Group

If you are a customer of Runtec, here’s what is being claimed, and what it would mean for you.

Runtec was listed on Lynx's leak site. Lynx claims to have stolen internal data. This is the group's claim, not a confirmed finding.

On May 2, 2025, Japanese logistics company Runtec Co., Ltd. appeared on the leak site of the lynx ransomware group, confirming that internal files had been exfiltrated during a ransomware attack. The breach affects anyone whose personal or business records passed through Runtec’s temperature-controlled food transport and storage network, which serves households and companies across Japan.

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.

What Public Reporting Shows

Public reporting indicates that Runtec, founded in 1953 and now part of the SENKO Group, was hit by ransomware operators who stole internal files. The company specializes in refrigerated transport and storage of food products with a nationwide network of branches headquartered in Fukuoka. Available reporting describes the data as internal files; exact volume and specific record types remain unconfirmed by the company. The listing appeared on the group’s leak site on May 02, 2025, following standard ransomware tactics of initial access, data theft, and public extortion pressure.

Why This Matters for You and Your Family

When a logistics provider that moves food across Japan suffers a breach, the ripple effects reach ordinary households. Delivery records, customer addresses, contact details, and supplier information can easily contain enough personal data to fuel identity theft or phishing campaigns aimed at you or your family. Internal files exfiltrated often include spreadsheets or databases that link names, phone numbers, and delivery locations—information that can be combined with other leaks to build a detailed profile of your daily routines and financial relationships.

Even if you never directly contracted with Runtec, your information may appear if you ordered groceries, used meal-kit services, or received shipments through retailers that rely on their network. The exposure puts your family’s privacy at immediate risk because stolen logistics data frequently surfaces in follow-on fraud schemes.

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.
