Comcast REUP FOR SALE reports that internal files were exfiltrated in a ransomware attack carried out by the spacebears group, the incident becoming public on 15 December 2025. Affected individuals should check the organisation’s breach-notification resources or contact Comcast directly to determine whether their information was involved and what protective steps to take.
What happened
The listing reported on December 15, 2025, states that an archive of approximately 2 TB contains samples of files from Comcast REUP FOR SALE. It describes the contents as including DWG drawings, PDF plans of various cities with infrastructure details, and other materials related to the Genesis project. The material is presented as a single lot for sale, with instructions to submit contact information through a feedback form. No confirmed count of affected individuals or confirmation of the exfiltration method has been made public.
Who is spacebears?
Spacebears is a ransomware group that has been publicly documented operating by encrypting systems, exfiltrating data, and posting victim information on leak sites when ransom demands are not met. The group’s typical pattern involves claiming responsibility for intrusions through such listings and offering portions of stolen material for sale. Its listing of Comcast REUP FOR SALE constitutes an unverified claim by the group; independent confirmation of the breach details has not been established in available reporting.
Who is Comcast REUP FOR SALE?
Comcast REUP FOR SALE appears to be an entity connected to Comcast Corporation, based on the corporate website referenced in the listing. Organizations in this sector routinely manage large volumes of engineering, planning, and infrastructure documentation. A breach involving such material can expose operational details that extend beyond the company itself to public infrastructure projects.
The information in question
The listing names internal files exfiltrated in a ransomware attack, specifically an archive of roughly 2 TB that includes DWG drawings, PDF plans of cities with infrastructure elements, and files tied to the Genesis project. The exact scope of any personal or customer data within those files remains undisclosed. Organizations of this type commonly hold records related to network infrastructure, project planning, and vendor communications, but the precise contents of the offered archive have not been independently verified.
Why it matters
Infrastructure-related files can reveal details about physical systems, city layouts, and project specifications that may be of interest to parties seeking to understand or interfere with those systems. For the organization, the incident adds to operational costs associated with incident response and potential remediation. For individuals, the primary exposure would arise if personal identifiers or account details were present among the internal records, though no such confirmation exists at this time.

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.
