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 SEL, also known as Safety Engineering Laboratory, was listed on the qilin ransomware group's data leak portal. The group states it exfiltrated internal data during a ransomware incident. No exact number of affected individuals has been disclosed, and the precise volume or sensitivity of the stolen files remains unclear from available reporting. The listing appeared on April 20, 2026, following the group's standard practice of publishing proof of compromise when victims do not pay.

Industry research from sources such as DoxxScan™ continuous monitoring indicates that employee or customer records exposed in such incidents frequently include names, contact details, and other personal information that can be repurposed for identity theft or further attacks.

Why This Matters for You and Your Family

When a laboratory or engineering firm suffers a breach, the data rarely stays contained. Internal files can hold email addresses, phone numbers, project details, or even personal records of employees and partners. If your information or that of a family member was connected to SEL, it may already be in the hands of criminals who specialize in turning stolen data into profit. Credential leaks like this one often cascade into account takeovers across other services where the same passwords or email addresses are reused.

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.
