3-D Engineering Listed by ALPHV Ransomware Group

If you are a customer of 3-D Engineering Corporation, here’s what is being claimed, and what it would mean for you.

3-D Engineering Corporation was founded to meet the growing demands for high quality outsourced Engineering Services. We recognized in 1998 as we do today, the need for High Quality, Cost Effective Solutions essential for today’s technology based companies. Since our inception, we have worked relentlessly to identify and integrate key engineering and manufacturing capabilities to serve our clients needs. Our core set of best practices and industry knowledge spans the entire product development life-cycle. This ranges from product requirements definition, analysis, concept creation, design d

3-D Engineering Listed by ALPHV Ransomware Group

On October 23, 2023, 3-D Engineering Corporation appeared on the leak site of the Alphv ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the Michigan-based engineering services provider. The company, which has offered outsourced product development and manufacturing support since 1998, has not yet published a public breach notification detailing the volume or exact nature of the exposed data.

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.

Details in the Leak-Site Listing

The Alphv leak page, accessible via the onion address hosted on ransomware.live, states that attackers gained access to 3-D Engineering’s network, encrypted systems, and removed unspecified internal files. The disclosure indicates the data was taken prior to encryption and is now available for download by other threat actors. No customer record count is provided, and the listing does not specify whether employee personal information, client contracts, CAD files, or financial documents were included. The group typically posts proof packets and sets a short payment deadline before full data publication; the exact deadline listed for 3-D Engineering has since passed.

Why This Matters for You and Your Family

When an engineering firm like 3-D Engineering suffers a ransomware breach, the information stolen often includes details that can be linked to real people. Employees, contractors, and clients may have had names, addresses, dates of birth, Social Security numbers, or direct-deposit banking information stored in the compromised files. Even if you never worked there, your data could appear if you were a vendor, customer, or if an employee reused a password shared across personal and work accounts. Once that information reaches dark-web marketplaces, identity thieves and stalkers can weaponize it for months or years.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently contain email addresses, usernames, phone numbers, and project notes that map directly to individuals. These fragments become the starting point for doxxing chains: an attacker links your work email to a personal gaming account, then to a family member’s address, building a complete profile. Credential leaks of this type routinely cascade into account takeovers on Steam, Roblox, Discord, and other platforms used by children and teens. A single exposed password from an engineering firm can therefore endanger not only your finances but also your family’s online safety and physical privacy.

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.
