Holiday Builders Listed by conti Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Holiday Builders Listed by conti Ransomware Group (reported December 22, 2021) 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.
People connected to Holiday Builders may face downstream consequences from the exposure of internal company files, even though the number of individuals affected remains unknown. The incident centers on a listing posted by the Conti ransomware group on 22 December 2021, in which the group stated it had taken data from the organisation.
Because the scale of the data and the identities of those potentially involved have not been published, affected individuals have limited visibility into whether their own information appears in the material. The practical question is what the files contain and how that material could be used.
Breaking down the breach
Holiday Builders appeared on the Conti ransomware group’s leak site on 22 December 2021. The group claims to have exfiltrated internal files during a ransomware operation. No figure for the volume of data or the number of people affected has been released, and the organisation has not confirmed or denied the claims in public statements available at the time of reporting.
Details on the method of initial access, the duration of the intrusion, or whether encryption was deployed alongside the data theft are not included in the available information. The only confirmed public element is the listing itself and the group’s assertion that internal data was removed.
Who is conti?
Conti is a ransomware operation that emerged publicly around 2020 and became known for a double-extortion model: encrypting systems and also copying data for later publication if a ransom demand was not met. The group maintained a leak site where it listed victim organisations and, in some cases, uploaded samples of stolen material.
Public reporting on Conti’s activity shows repeated targeting of mid-sized companies across multiple sectors, with operators often using commodity initial-access techniques before deploying custom ransomware. The group largely ceased visible operations after a series of law-enforcement actions and infrastructure disruptions in 2022.
Holiday Builders and its sector
Holiday Builders operates in the residential construction sector, building homes and managing related contracts, suppliers, and customer records. Companies of this type routinely maintain files on employees, subcontractors, home buyers, financing arrangements, and project documentation.
A breach at such an organisation can therefore touch both personal identifiers and commercial information that is not normally public. The absence of Reported Details about the contents of the exfiltrated files leaves open the possibility that any of these categories could be present.
What was likely exposed
The only description provided is that internal files were taken. No inventory of file types, no list of data fields, and no confirmation of personal information have been released by either the organisation or the group.
Organisations in residential construction commonly store employee records, customer contracts, financial documentation, and supplier details. Whether any of these categories appear in the material claimed by Conti is unconfirmed.
What's at stake
Internal files can contain information that enables targeted fraud or account takeover if personal or financial details are present. For the organisation, the exposure may complicate relationships with customers, lenders, and regulators even if the precise contents remain unknown.
Because the number of individuals involved is undisclosed, the incident’s reach cannot yet be measured. The primary uncertainty is whether the files contain data that can be directly linked to specific people.
If your data was in this claimed breach
Individuals who have done business with or worked for Holiday Builders can take the following steps while waiting for further disclosure:
- Monitor bank and credit accounts for unusual activity.
- Place a fraud alert or credit freeze with major credit bureaus if statements or tax documents could be affected.
- Run a free exposure scan of their email address against known breach data sets to check for additional appearances.
- Retain any future notification from the company for details on what was taken and any offered remediation.

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.
