clc-tn.com Listed by settra Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On June 30, 2026, the domain clc-tn.com appeared on a listing associated with the settra ransomware group. The entry described the target as City Lumber Company, a building-materials supplier operating in Tennessee, and stated that internal files had been removed during a ransomware incident. No figure for the number of individuals affected has been released, and the full scope of the data involved remains undisclosed in public reporting.

Inside the incident

The only confirmed public detail is the listing itself and the brief description of exfiltrated internal files. No date of the underlying intrusion, volume of data, or encryption status has been published. The organisation has not issued a statement confirming or denying the claims, and independent verification of the files’ contents has not been made available.

The group behind it: settra

Settra is a ransomware operator that maintains a public leak site where it lists organisations it claims to have compromised. Like other groups in this category, it typically combines file encryption on victim systems with the removal of copies of data, then uses the threat of publication to press for payment. The group’s listings are presented by the actors themselves; independent confirmation of each claim is not automatic and must be assessed case by case.

Who is clc-tn.com?

clc-tn.com is the online presence of City Lumber Company, a supplier of building materials based in Tennessee. Companies of this type routinely maintain records that include customer accounts, supplier contracts, pricing information, delivery schedules and internal operational documents. A breach at such a firm can therefore expose both commercial data and any personal information that customers or employees have provided in the course of business.

The information in question

The listing refers only to “internal files.” No inventory of specific data categories has been released. Organisations in the building-materials sector commonly hold customer contact details, order histories, credit or payment information, and employee records, yet the precise contents of the exfiltrated material in this case have not been confirmed.

The real-world impact

Exposed internal files can reveal business relationships, pricing structures and operational procedures that competitors or other parties might exploit. If customer or employee personal data is present, those individuals face the ordinary risks associated with leaked contact or account information, such as targeted phishing or attempts to misuse credentials. The organisation itself may incur costs related to investigation, notification and remediation, though the scale of those costs is not yet known.

If your data was in this claimed breach

Individuals who have done business with City Lumber Company or who work there should monitor their email and financial accounts for unusual activity. Enabling multi-factor authentication on any accounts that may share passwords with the affected organisation is a standard precaution. Readers can also run a free exposure scan of their email address against known breach data sets to determine whether their information appears in publicly reported incidents.
