On May 02, 2023, Austrian company hasenauer-anlagenbau.at appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack. The number of records affected remains unknown, and the precise data types contained in the files have not been detailed by the group.

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.

Reported Details from the Listing

The LockBit 3.0 leak page explicitly lists hasenauer-anlagenbau.at as a victim and claims successful data exfiltration. It presents the company’s own description of its work in water, heating, cooling, air and climate systems but does not publish sample files or specify what internal documents were taken. The disclosure indicates the data is held for extortion purposes, a standard LockBit tactic. No customer record count is provided, and the exact date of initial compromise is not stated in the listing.

Internal files exfiltrated is the only description of compromised material given. The leak site does not quantify the volume of data or name specific databases or servers that were accessed.

Why This Matters for You and Your Family

When a local business that handles planning, installation, and service contracts for homes is breached, the files taken can easily contain names, addresses, phone numbers, email addresses, and payment details of residential customers. If you or your family have ever used an Austrian installer for heating, cooling, or climate-control systems, your information may be among the stolen material even though the exact number of affected individuals is unknown.

Businesses like this often store project documentation that links customer identities to physical locations. A single leaked spreadsheet can give attackers the combination of personal data and home addresses they need to escalate from simple identity theft to targeted harassment or burglary planning.

The Doxxing and Identity-Chain Risk

Exposed internal files frequently contain more than names and addresses. They can include employee contact lists, supplier contracts, email correspondence, and notes that link online handles to real-world identities. Once attackers possess these connections, they can chain one breach to another, locating your gaming accounts, social-media profiles, or family members’ accounts that reuse the same email or password.

Credential leaks like this one cascade into account takeovers and doxxing chains. Children’s gaming accounts are especially vulnerable because parents often share email addresses across family services. A single exposed business file can therefore expose an entire household’s digital footprint.

LockBit 3.0 Track Record

Public reporting attributes LockBit’s first appearance to 2019. The group rebranded as LockBit 3.0 in early 2023 after law-enforcement action against earlier infrastructure. Notable prior victims include numerous small and mid-sized businesses across Europe and North America, many in the construction, manufacturing, and professional-services sectors. Their typical playbook begins with initial access via compromised remote-desktop credentials or phishing, followed by rapid lateral movement, data exfiltration, and then dual extortion: demanding ransom for decryption and threatening public release of stolen files. The group routinely sets short deadlines and leaks data when payment is not received.

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.
  • Rotate any password you used at hasenauer-anlagenbau.at or any related supplier site, and enable 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught in hours instead of months.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
  • Let remediation specialists handle ongoing takedown requests across data brokers and leak sites for you.

The incident shows how quickly a single compromised vendor can pull ordinary families into a ransomware operator’s extortion machine. Staying ahead requires more than changing one password; it demands continuous visibility and expert help. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.

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.
