Thiekon Constructie Listed by INC Ransom Ransomware Group

If you are a customer of Thiekon Constructie, here’s what is being claimed, and what it would mean for you.

Thiekon Constructie BV is a company from Reijen (Netherlands) with more than 40 years of experience in steel structures and zinc coatings. It is the only one in the country with its own hot-dip galvanizing plant, which allows steel processing within a single company. The company performs fabrication and assembly of steel elements (from small parts to complete structures) and provides powder coating service on request. This provides a centralized approach to work using steel, zinc and painting technologies.

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.

Reported Details of the Incident

Public reporting indicates that Thiekon Constructie, based in Reijen, was listed on the incransom leak portal with samples of allegedly stolen data. The company, which has more than 40 years of experience in steel structures, zinc coatings, and powder coating services, appears to have been targeted in a typical ransomware operation involving both encryption and data theft. No exact victim count or full list of exposed file types has been publicly detailed beyond the broad description of internal files. The incident follows the group’s standard pattern of publishing victim data when ransom demands are not met.

Why This Matters for You and Your Family

When a company like Thiekon Constructie suffers a breach, the information inside its files can easily include names, addresses, contact details, and financial records of customers, suppliers, and partners. If your family has ever worked with a steel fabricator, construction firm, or similar business in the Netherlands, your personal data may now sit in an attacker’s archive. Once leaked, this information does not expire; it can be sold, traded, or used months or years later to target you with phishing, identity theft, or physical scams. Children’s names linked to a parent’s work address can also surface in gaming communities or social platforms, creating unexpected exposure.

The Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one company. A single exposed email, phone number, or home address becomes the starting point for an identity chain that links your professional life to personal accounts across the internet. Attackers cross-reference the data with information from earlier breaches, building a map that can reveal your children’s usernames, school details, or gaming profiles. Credential leaks of this kind frequently cascade into account takeovers on email, banking, or social media, followed by demands for payment or further data release. Available reporting describes these chains as accelerating once initial records appear on dark-web leak sites.

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.
