ACR1.COM Commercial Roofing Listed by qilin Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
ACR1.COM Commercial Roofing was listed by the qilin ransomware group on March 27, 2026, after internal files were exfiltrated in a ransomware attack affecting an undisclosed number of people. Individuals who may have had dealings with the company should review any communications or accounts for signs of exposure and take appropriate protective steps.
What happened
ACR1.COM Commercial Roofing was added to the Qilin ransomware group’s leak site on the reported date. The group claims to have stolen internal data from the organisation. No further details on the timing of the intrusion, the method used to gain access, the volume of material taken, or any ransom demand have been made public. The number of individuals whose information may be involved is also unknown.
Inside qilin
Qilin operates as a ransomware-as-a-service group. It develops encryption tools and maintains a leak platform where stolen files are posted when victims do not meet its demands. The group has previously targeted organisations in construction, manufacturing and professional services. Its standard approach includes both encrypting systems and copying data for later publication or sale. Listings on its site represent the group’s own assertions and are not independently verified in every case.
About ACR1.COM Commercial Roofing
ACR1.COM Commercial Roofing provides roofing services to commercial clients. Companies in this sector routinely collect and store project specifications, contract details, financial records, employee information and communications with customers and subcontractors. A breach at such a firm can expose both the company’s own operational records and data belonging to the businesses and individuals it serves.
What was likely exposed
The only information released so far is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been confirmed. Organisations of this type commonly hold names, addresses, contact details, financial documents and project-related correspondence. Without a published inventory, it is not possible to state which of these categories, if any, were included in the material taken.
Why it matters
Exposure of internal files can lead to follow-on fraud, targeted phishing or misuse of commercial information. For employees, the risk may involve personal identifiers or payroll data. For clients, project or contract details could be used to impersonate the company or its partners. The organisation itself faces potential operational disruption and the cost of restoring systems and reviewing its security controls.
If your data was in this claimed breach

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.
