Bonacio Construction Breached by RansomHouse: Ransomware Claim — What’s Alleged & What To Do
Bonacio Construction was breached by RansomHouse on June 30, 2026, with business data exposed. Check whether your information was involved and take protective steps.
Breaking down the breach
The only confirmed information is the date the claim appeared and the identity of the listed organization. RansomHouse asserted that it had taken business data belonging to Bonacio Inc., a firm described in the listing as operating in construction, real estate development, and property management. No independent confirmation of the data’s authenticity or scope has been published, and the number of people potentially affected remains unknown. Initial reports contain no information on whether files were encrypted, exfiltrated, or both.
Who is ransomhouse?
RansomHouse is a ransomware group that has operated since at least 2021 and is known for publishing stolen data on a dedicated leak site when victims decline to pay. The group typically uses double-extortion tactics, combining encryption of systems with the threat of data release. Its targets have included organizations across multiple industries, and it has maintained a public presence through claims posted on its site and on data-breach tracking platforms such as Breachsense.
About Bonacio Inc
Bonacio Inc. provides full-service construction, real estate development, and property management. Organizations in this sector routinely maintain records related to project bids, client contracts, financial transactions, employee information, and tenant or property-owner details. A breach affecting such a firm can expose operational and commercial information that is not always subject to the same regulatory scrutiny as personal health or financial data.
What was likely exposed
The listing refers only to “business data.” No further categories have been disclosed. Companies of this type commonly hold project documentation, vendor and subcontractor records, financial statements, and contact information for clients and employees. Because the exact contents remain unconfirmed, it is not possible to state which specific records, if any, were taken.
The real-world impact
Exposure of business records can lead to competitive disadvantage, contract disputes, or follow-on fraud attempts if contact or financial details are involved. For individuals whose information appears in those records, the primary risks are phishing, account takeover, or misuse of personal identifiers. The organization itself may face operational disruption and costs associated with investigation and remediation, though the scale of any such effects has not been reported.
If your data was in this breach
Individuals concerned about possible exposure should monitor their financial accounts and credit reports for unusual activity. Changing passwords for any accounts linked to the organization and enabling multi-factor authentication where available are standard first steps. Readers can run a free exposure scan of their email address to check whether their information has appeared in known breach data sets.

Publicly posted by ransomhouse — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
