agy.com Listed by Black Basta Ransomware Group

On November 03, 2023, industrial manufacturer AGY appeared on the leak site of the Black Basta ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the company, which produces high-performance glass fiber yarns and reinforcements used in electronics, aerospace, defense, and consumer markets. Anyone whose personal or employment data touched AGY’s systems may now be exposed.

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.

Primary Disclosure Details

The Black Basta leak site entry for agy.com states that attackers extracted internal files but does not specify the volume of data taken or name the exact record count. The disclosure indicates the material was obtained through a ransomware deployment, a standard claim on these sites. No customer, employee, or partner numbers are published, and the listing does not detail which categories of files—such as spreadsheets, emails, or databases—were allegedly stolen. The notice simply states that the data is now available for download by anyone who pays the group’s fee or waits for it to be released publicly.

Why This Matters for You and Your Family

When a manufacturing company like AGY suffers a breach, the exposed internal files often contain information that reaches beyond the corporate perimeter. Employees’ personal details, vendor contact records, and partner agreements can appear in the same archives. If your name, address, email, phone number, or Social Security number was stored in any of those systems, it is now at risk of being sold or published. For families this can mean sudden spikes in targeted phishing, identity-theft attempts, or unwanted solicitations that affect household finances and peace of mind.

November 03, 2023 marks the moment the data became openly advertised for extortion. Once ransomware groups list a victim, the clock starts for both the company and every individual whose records were swept up.

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.
