Sanko Air Conditioning Co., Ltd. Listed by Qilin Ransomware Group

If you are a customer of Sanko Air Conditioning Co., Ltd., here’s what is being claimed, and what it would mean for you.

Sanko Air Conditioning Co., Ltd. was listed on the qilin ransomware leak site. The group claims to have stolen internal data.
— from Qilin’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

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.

What Public Reporting Shows

Public reporting indicates that Sanko Air Conditioning was listed on the qilin leak portal with a notice that internal company data had been exfiltrated. The exact volume of records and the total number of people whose information may be exposed remain unknown. Available details describe the exposed material as internal files rather than a structured database of customer records, though such files frequently contain employee names, contact information, contracts, and other personal data.

December 7, 2025 marks the public listing date. The qilin group’s standard practice is to give victims a short window to negotiate before releasing samples or the full archive. No independent verification of the stolen data contents has been published, but ransomware.live tracks the listing as active.

Why This Matters for You and Your Family

When a company that handles residential or commercial air-conditioning contracts is breached, the information inside its files can include your name, home address, phone number, email, payment details, and sometimes the names of family members listed on service agreements. If those details reach the open web, they become raw material for identity theft, phishing campaigns, and harassment. Even if you never directly hired Sanko, vendor lists, subcontractor records, or employee spreadsheets can still expose ordinary households.

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.
