Reported Details of the Breach

Public reporting indicates that Delta Manufacturing, a company specializing in custom electric heating elements for aerospace, medical, food, and chemical industries, had its systems compromised in a ransomware incident. The attackers successfully exfiltrated internal files before encrypting systems or otherwise disrupting operations. Available reporting describes the exposed data as including customer and employee details along with contracts, all accounting records, and invoices. The exact number of individuals affected remains unknown at this time.

The incident follows a pattern seen in many ransomware cases where initial access leads to data theft followed by public threats to release or sell the information. interlock listed Delta Manufacturing on its leak site on March 18, 2026, giving the company a limited window to respond before further publication of the stolen files.

Why This Matters for You and Your Family

If you or any member of your family has ever done business with Delta Manufacturing, your personal or financial information may now be in the hands of criminals. Employee records, customer contracts, and accounting documents often contain names, addresses, phone numbers, email accounts, payment details, and sometimes Social Security numbers or tax information. Once this type of data leaves a company’s control, it rarely stays contained.

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.
