Master Manufacturing Co., Inc. Listed by Dark Project Ransomware Group

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

Master Manufacturing Co specializing in custom metal stamping and production services has fallen victim to a significant cyberattack. Hackers reportedly exfiltrated 36 gigabytes of sensitive data from the company’s servers. The stolen information includes SQL databases containing personal data, as well as technical plans and schematics for custom metal parts. The breach raises serious concerns regarding intellectual property theft and potential privacy violations for employees and clients.
— from Darkproject’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.

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.
