elmatic.de Listed by blackbasta Ransomware Group

On February 20, 2024, German engineering firm elmatic.de appeared on the leak site operated by the Black Basta ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The company, which specializes in planning, construction, maintenance and renovation of buildings and production facilities as well as energy management and thermal apparatus development, has not yet published a public breach notification detailing the number of people affected or the exact records involved.

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 582 companies.

Details from the Leak Site

The Black Basta leak page for elmatic.de states that data was stolen and is being held for extortion. The primary disclosure does not quantify the volume or specific categories of information taken, nor does it list any deadlines for payment. It simply presents the company name, a sample of presumably stolen documents, and the standard ransom note format used by the group. Public mirrors of the onion site, such as those aggregated on ransomware.live, preserve this listing exactly as posted.

Internal files were allegedly exfiltrated, according to the disclosure. No customer, employee, or partner record count is provided, leaving the full scope unknown to the public at this time.

Why This Matters for You and Your Family

When a company like elmatic.de that works on commercial and residential building systems suffers a breach, the exposed data can easily include contracts, contact lists, employee details, or operational blueprints that reference real people. If your employer, your home builder, your energy-management provider, or any firm you have dealt with uses elmatic.de, your personal information may now sit in an attacker-controlled archive. Even without exact victim counts, the reality is that ransomware operators rarely limit themselves to corporate secrets; personal identifiable information often travels with the rest of the haul.

February 20, 2024 marks the moment this particular dataset became public. From that date forward, anyone whose details appear in those files faces an elevated risk that the information will be sold, swapped, or used to launch further attacks against them or their families.

Doxxing and Identity-Chain Risks

Stolen internal files frequently contain spreadsheets that link names, email addresses, phone numbers, physical addresses, and sometimes dates of birth. Attackers and subsequent buyers can chain these pieces together with information from other breaches to build detailed profiles. A work email from the elmatic.de leak can be matched to a personal account exposed elsewhere, revealing family members, children’s schools, or even gaming usernames. These chains accelerate doxxing because one exposed credential often unlocks multiple online services that were never directly targeted.

Credential leaks of this nature routinely cascade into account takeovers on gaming platforms. Children’s accounts tied to a parent’s reused email or phone number become easy secondary targets, turning a corporate ransomware incident into household-level harassment or identity theft.

Black Basta’s Known Track Record

Public reporting attributes the first Black Basta operations to early 2022. The group rapidly gained notoriety for double-extortion tactics: encrypting victim networks while simultaneously exfiltrating data and threatening to publish it unless a ransom is paid. Notable prior victims have included large manufacturing companies, healthcare providers, and professional services firms across North America and Europe. Their typical playbook begins with initial access gained through compromised remote desktop credentials or phishing, followed by lateral movement, data theft, deployment of their custom ransomware, and finally posting samples on their leak site when negotiations stall. The exact name “Black Basta” is the label they use themselves and the one tracked by law enforcement and cybersecurity firms worldwide.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught in hours rather than months.
  • Rotate any password you ever used at elmatic.de or any related service, replace it with a unique passphrase, and secure the account with 2FA through an authenticator app instead of SMS.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often chain back to the same addresses or parent emails exposed in corporate leaks.
  • Let remediation specialists handle takedown requests across data brokers and leak forums on your behalf while you focus on securing your own logins.

The elmatic.de listing is a reminder that ransomware operators continue to treat stolen personal data as leverage long after the corporate ransom deadline passes. Staying ahead requires more than changing one password. Start your DoxxScan trial and combine its continuous monitoring, AI-powered identity-chain mapping, and hands-on remediation by specialists with basic hygiene to reduce the chance that this or any future breach turns into lasting harm for you or your family. DoxxScan is also effective for protecting gaming accounts because credential leaks like this one routinely cascade into account takeovers and doxxing chains.

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.

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.
