The kainz-haustechn. Listed by lockbit2 Ransomware Group (reported April 18, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On April 18, 2022, kainz-haustechn. appeared on the leak site maintained by the LockBit 2.0 ransomware group. The listing states that internal files were taken from the organisation, though the number of people affected and the exact nature or volume of the data have not been publicly confirmed.
What happened
The only confirmed information is the appearance of kainz-haustechn. on the LockBit 2.0 leak site on the reported date. The group claims to have exfiltrated internal files during a ransomware operation. No further details on the timing of the intrusion, the method of access, the scale of the data taken, or any ransom demand have been disclosed by either the organisation or the group.
Who is lockbit2?
LockBit 2.0 is the name used by a ransomware-as-a-service operation that first appeared in public reporting in 2019 and released an updated version in 2021. The group supplies encryption tools to affiliate attackers in exchange for a share of ransom payments. Its standard approach involves encrypting files on targeted systems and threatening to publish stolen data if payment is not received. The group has listed organisations from multiple countries and sectors on its leak site, though each listing remains an unverified claim until independently confirmed.
About kainz-haustechn.
kainz-haustechn. operates in the building-services sector, providing heating, plumbing and related technical installations. Companies of this type routinely collect and store customer contact details, contract information, project specifications, supplier records and internal operational documents. A breach at such a firm can expose both personal data of clients and proprietary business information that is not normally available to the public.
What was likely exposed
The facts released so far refer only to “internal files exfiltrated in ransomware attack.” No specific categories of data, such as names, addresses, financial records or technical drawings, have been identified. Organisations in this sector commonly hold customer account information, service contracts and employee records, but the precise contents of the files claimed by the group remain unconfirmed.
Why it matters
Exposure of internal files can create practical risks for individuals whose details appear in contracts or service records, including potential misuse for fraud or unwanted contact. For the organisation, the incident may complicate client relationships and require additional security measures. Because the number of affected people and the sensitivity of the files are unknown, the full scope of consequences cannot yet be assessed.

Standard precautions include reviewing bank and credit accounts for unusual activity, changing passwords on any shared accounts, and enabling multi-factor authentication where available.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
